Gardner ENGINES

Like Windrush I too spent hours rebuilding Gardners. Part of the problems of the late 70’s and on, can I think be laid at the door of the Lorry manufacturers’ and oil companies’ marketing men. The buzz words at the time were unladen weight and standardization. The result was that the lorry builders fitted radiators that simply weren’t up to the job in their quest for light weight; the Seddon Atkinson 400 being particularly bad. This worked OK for the ■■■■■■■ and Rolls, but the Gardner ran cooler and would overheat at a lower temperature than the other makes. It was also a time when little notice was taken of maintaining year round anti-freeze strength, nor of ensuring that the water was not too hard. The radiators on so many of the engines taken apart were blocked. With the Gardner climbing the hills slower than other engines, the airflow was insufficient to prevent overheating. Oddly most of the engines I saw had seized nos 2 and 5, so as is so common, different parts of the country experience different problems.

The oil companies were going big on the idea of “fleet oils” to suit every vehicle from the company car to the maximum weight HGV . These most certainly did not suit the Gardner, which polished its bores and gummed up the rings on these oils. Gardner themselves were to blame because chromium plated liners on the LXC made the problem even worse.

I suppose it is a toss up for which job I hated more: trying to fit the cambox oil return O ring on a Gardner, or pulling the heads down to something like 400 lb ft on a ■■■■■■■ 180/220 in a fixed cab.

gingerfold:
Hugh Gardner, the autocratic MD of Gardners, would not contemplate turbo-charging a Gardner engine. He considered it to be “cheating”, irrespective of where the marketplace had moved on to by the 1970s. His brother John, who with Hugh had designed the world’s first successful direct injection diesel engine for automotive purposes in 1930 was more open minded, and John’s son Paul was tasked with a secret project to design a turbo-charged Gardner. It was carried out in the spares warehouse, away from the main factory and Hugh Gardner’s prying eyes, but undoubtedly he knew what was going on. When Hawker Siddley bought Gardners in 1976, and Hugh eventually retired, Hawker’s experience of turbo-charging from its Lister engines division was used by Paul Gardner.

Incidentally, Hugh Gardner’s stance on turbo-charging echoed that of W.O. Bentley in the 1920s. Bentley, who was principally an engine designer would not contemplate supercharging his car engines, which had been successful at Le Mans, and by the late 1920s were rivalled by more powerful (but less reliable supercharged Mercedes). Although Bentley is principally remembered for its four consecutive wins at Le Mans in the late 1920s, including its famous supercharged four and a half litre blower Bentleys, the supercharging of Bentley engines was initially a private venture, started by Tim Birkin, one of the Bentley racing team drivers, funded by the Hon. Dorothy Paget, and extremely wealthy and very eccentric lady.

The fact is there’s a big difference between making a reliable forced induction engine that’s designed from the outset to be run with forced induction compared to just bolting a supercharger or turbocharger onto an existing naturally aspirated engine design that’s not designed for it.The likes of WO and Hugh Gardner were rightly thinking along those lines in their views as the state of the art stood (at that time).They knew that there was no way that the existing technology,which they had at their disposal,was up to the job.The Birkin specials actually proved WO correct by not being able to win in their own right they were just able to stand up to forced induction a bit longer than ze German machines could which meant the Mercs broke first in trying to stay with the supercharged 4.5 litre Bentlys thereby allowing the more reliable naturally aspirated speed six to win.

Luckily for the civilised world it was the likes of Rolls aero division who were working at the real cutting edge of making forced induction work reliably as the state of the art stood in WO’s and Hugh Gardner’s time.

But having said that there’s always the exceptions which prove the rule.In that case it would be the success of effectively just turbocharging the production naturally aspirated Merc V8 in the group C C 9 and C 11 cars and the way in which the Leyland 680, ■■■■■■■■■■■ the Detroit two strokes took to being turbocharged like ducks to water.However there’s no way that engineers like WO and Hugh Gardner would have based the future of their companies on those types of exceptions in the future which no one at that time even knew about and which as history showed,the basis of Gardner’s engineering followed that general rule that engineering,that’s not designed from the outset to be run with forced induction,usually won’t be up to the job as a retro fit or an after thought.

Which just leaves the question of if only we could have seen what the Jag V 12 engine could have done at Le Mans with forced induction and wether,like the 680,■■■■■■■■■■■■■■■ and the Merc V 8 it would have been one of the exceptions which proved WO’s and Hugh Gardner’s rule. :wink:

Well, well, well, it would appear that Carryfast is sticking up for the Patricroft Powerhouses :open_mouth:

In some ways the fact that Gardner would not (rightly) turbocharge a design that was not meant to be turbocharged is a good thing. It meant that their engines were likely to last a hell of a lot longer, but it also contributed to their demise. Everyone else redesigned things or designed new engines to accomodate turbocharging and the rest is history :wink:

Folk tend to blame engine manufactures for problems, but often it is the ancillary components that are the weak link in the chain. I agree with cav551 that radiators were part of the problem, we always sent the rad away whenever an engine failed and they usually had a blockage somewhere, and that was running with 50% antifreeze. When the Foden Haulmaster came into our fleet they were fitted with the wrong radiator cores so had to be swapped under warranty, Foden supplied the new cores and we fitted them, also the cylinder heads were found to be troublesome on the 6LXC’s so LXB heads were fitted, again under warranty. You cannot beat a good tall radiator which is higher than the engine, you get a good head of water so that the head etc is always well covered with coolant. BMC had that problem when they fitted the inclined 5.1 and 5.7 engines in the FJ series, they used a low mounted crossflow radiator that was plagued with airlocks resulting in appalling warranty claims for blown head gaskets and dropped cylinder liners, yet the same engine when fitted in the earlier FH series with a tall radiator gave very little trouble.

^ + 1.

Probably more a case of sticking up for the reasoning behind WO’s and Hugh Gardner’s resistance to the idea of forced induction engines as the state of the art stood during their time.

Although to be fair maybe it was more a matter of luck than judgement that ■■■■■■■ and GM/Detroit just happened to have designed some non turbocharged motors by accident that turned out to be happier and better running with turbocharging than they were running in non turbo form as they’d been designed at the outset. :bulb:

Which just leaves the case of the Leyland 680 in being the real loss because of the stupidity of those who should have known better in not making something like the DAF 2800 line first instead of just handing the initiative to the Dutch on the basis,that unlike the American engineers,they couldn’t be bothered to actually find out what the thing was capable of before just giving it away.Although to be fair again how many British customers were asking Leyland to put a turbocharged engine in it’s products before the Dutch started work on the job and/or at the same time as US customers were calling on ■■■■■■■ to provide more power in it’s products :question: . :bulb:

As Bewick,rightly,points out during the 1960’s and 1970’s many,if not most,British customers still thought that the (correct for the time) 1930’s type thinking of WO and Hugh Gardner was still the state of the art for a truck engine at that time and were still paying for the privilege while moaning about being offered a Guy Big J with a turbocharged ■■■■■■■ in it because Gardner’s couldn’t keep up with the demand in the domestic market for their old 1930’s technology. :open_mouth:

And on that bombshell Bewick seems to have shot down his own case that the demise of the British truck manufacturing industry wasn’t mostly the fault of the customers in the domestic market and proved mine that it was. :open_mouth: :smiling_imp: :laughing:

I found this picture in the Gardner archives, it was taken during the meeting they had to upgrade their product line and bring the company into the 20th Century :wink:

Although having said that we’ve established that the thing was so slow going up hills that it couldn’t provide sufficient airflow through the rad to stop itself from being cooked,whatever rad was in it,and in the winter it was a case of wether the driver could get home in time before frost bite set in because of the lack of heat. :open_mouth: :smiling_imp: :laughing:

I don’t mind at all,unless of course,CF was stood behind with his trousers round his ankles !!! Bewick.

Sadly I’m too young to have driven one but remember riding in Dads’ B501 AUD, a Foden 8w that had a badge proudly proclaiming “Gardner 270 turbo”… :laughing:
Eaton Twin Split, Wilcox alloy body…Dad loved it and would drive it even today over modern kit. He reckons oil use was no worse than any other wagon Smiths ran but the 270 did struggle on the get-go compared to the Cat 300s that ended Smiths association with Gardner (last Gardner was C reg).
Oddly, I loved the pull cable to stop it as quite often that was my job :laughing:
Said lorry had one major breakdown, on it’s final trip empty to head office to have it’s signwriting removed for sale; I believe it decided to leave a piston near the bosses’ house! :laughing:

Sent from a driver who’d love to drive an 8w with the 180…just for the experience.

Evening all, great contributions from everyone, windrush, cav551, superb inside, (literaly) real working knowledge. gingerfold has probably more knowledge of Gardner, the company, based on close and valid research, than anyone outside of the actual business. Bewick, and others have put their money down and run them, 6&8 cylinders, in whatever chassis they came, and know first hand the success or failure in operation of these engines. cav & windrushes point about installation being critical to success in operation is a very valid one indeed, and often overlooked in the heat of argument as to the quality of the product, or its manufacturer.
In the early pioneering days of diesel engined vehicles, late 1920s to early 1930s, you had MAN, Daimler Benz, ■■■■■■■■ AEC, Dennis, Saurer, Leyland,an Gardner. The only engines with direct injection into piston cavity combustion chambers being ■■■■■■■■ Gardner and Leyland. From those early days Gardners fuel economy, coupled to light installed weight,and dependable longevity, was the bench mark for all others to meet, let alone exceed.

That Gardner was ill served by some of its managements decisions is without doubt, particularly regarding control of labour cost inflation, resulting in the long protracted strike , from which it never really recovered. In todays world the economic argument put to a more market aware and realistic Union, would perhaps have resulted in a less damaging course of action. But that is supposition based on hindsight, and ignores the apparent intransigent management stance.

The market changed, a premium price for a (reputation wise), premium product, that would last for many, many years, did not hold in the 80s. Larger groupings, and centralised purchasing functions of transport companies, the rapid change from outright acquisition, to hire for a defined period, (encouraged by the rush to “off balance sheet funding”, encouraged by the introduction of SSAP21 Standard Accounting Practice). The consequential short first ownership life, coupled with the indefinable damage caused by Gardners previous dismissive attitude towards its customer base, both vehicle assemblers, and end users, did them no favours in the domestic market place. And Gardners aparent lack of realisation that its European licence builders, Bernard in France, and Kromhout in the low countries could have helped provide product to supplement their first supply problems in the late 60s, early 70s did not help.

Then along came Hawker Siddley, lots of investment, at the wrong time, and perhaps in the wrong direction, but they saw Gardner as undoubtedly the Jewel in their crown. The world was moving away from Gardners naturally aspirated designs, true just bolting on a Turbocharger could , and did bring its own problems, in France Willeme had all but lost its premium reputation by turbocharging its 13.45litre straight 6 586TC from 190 to 255hp, with the consequential unreliability, (and forced the adoption of AEC engines). The LXC 10.45 litre gave 201 BS hp, but the market required 200hp plus, (and the LXC had real quality problems). The 6 LXDT, 12.7litres giving initially 270hp, was uprated to 290 hp, and I believe intercooled versions were tried at 310hp by Perkins. But the confusion in marketing remained with Perkins, for at the same time they had the 15.5litre 6LYT. Right at the start of its life, in the mid eighties with a power output of 350hp, but designed to give 500,hp plus, with a net installed weight lighter than any 300hp engine of whatever swept volume at the time. Remember Volvo were yet preparing to launch their 16litre engine. But where would this new engine be produced, Patricroft? but part was closed to save money. I understand that plans were mooted to assemble engines at Bus Engineering at Chiswick! Did this ever happen, and can our more knowlegeable contributors fill in the final demise of Gardner, truly a tragedy of Shakespearean proportions! Cheerio for now.

At this late hour I am quite unable to absorb and process this very well crafted and most informative spiel of “Saviem’s” So I’m going to turn in !! To-morrow is another day when I will eagerly return to this comprehensive post and apply “my undivided” attention.While I will be engrossed in the task no doubt “Saviem” will be charging round the village on the J D annoying the early morning Church goers !!! Cheers and Good evening all !

Now you mention the bus engine division Saviem you really do open that can with the worm label :open_mouth:

Did the bus engines suffer from the same cooling issues as the lorry engines :question: I would say not, the bus has to continually stop and start, which generates a lot of heat, some buses run a rear engine layout, which again causes cooling problems, but they never seemed to be broken down all the time. The smoking issue never seemed to be a problem either, not when compared to the lorry engines anyway. Come to think of it, the showmen love them and used them as generators, they never smoked or overheated :exclamation:

To be fair to Gardner’s their truck engines were really developed from industrial and marine units, well documented in gingerfolds excellent book, and it was Trevor Barton of Nottingham that first had the idea of fitting one in a Lancia bus that his company ran. Of course at that time the engines were all cast iron as weight wasn’t a problem, but when hauliers started fitting them to replace thirsty petrol units the LW/LK range’s came into being with alloy components. If you look at a pre war LW and compare it to a 1970’s LXB there is not a lot of difference externally so the basic design still remained close to the marine units of the 1920’s, apart from the use of aluminium components for crankcase etc. That Gardner remained faithfull to that design for around fifty plus years must be testament to a proven design in the first place, it was just the fact that the transport world moved on very rapidly during the seventies and eighties requiring more power for higher weights that proved their downfall. Their place in road transport development cannot be doubted though.

The surprising thing is how the Gardner fans never give up even when the evidence is overwhelming although full marks to the Arriva driver for trying his best to finish it off but it just wouldn’t give up like all of them. :open_mouth: :smiling_imp: :laughing:

This thread really goes to show one thing, those who remember the pre 70s Gardner have a totally different opinion than those who remember the Gardner’s of the 80s :open_mouth:

In my Dad’s day the best lorries on the road were Atkinsons and Fodens, they had a Gardner engine in them, without exception. Both companies thrived for many years and their products were the backbone of British Haulage, so those old Gardners can’t have been that bad :open_mouth:

In my day anything with a Gardner was not a lorry I wanted to drive, by that time things had moved on and the industry had changed, lucky me :sunglasses:

Gardner are a legend in the lorry world, and rightfully so, it is a great shame that they never continued to innovate as they did at the start :cry:

That’s the thing in 1960 there was no motorways and lorrys trundling up and down the a roads of Britain and this was what the Gardner was built for. By 1980 we had hundreds of miles of motorway and lorrys running heavier and at 60 miles an hour plus and the older engines just didn’t cut it.
The only Gardner powered truck I haver ever drove was a well work e reg 1988 foden with the 270 turbo and it wasnt bad but I was told at the time it was bought new the same truck with a cat 3306 or l10 ■■■■■■■ would have been about 4k cheaper and were both quality engines and the ■■■■■■■ in particular was very good on fuel.

I had a 230 6lxct and she would do 9.5-10mpg. replaced it with a 270 6lxdt and that was a lot nicer to drive although in the same truck,that dropped the mpg to around 9. Next Foden was a 3306 Cat and 8-8.5mpg was about the best you could get. That extra fuel used was money in my pocket and that was why hauliers bought them. To be honest I have had a NHC 250 ■■■■■■■ and a L10 and neither could hold a candle to the Gardner for fuel consumption.

I think we often don’t take into account the speed we cover the gound at when comparing fuel usage.

I’ll lay odds that a 14 litre ■■■■■■■ driven by someone competent following a Gardner engined truck of equal weight would be just as economical, in practice when i drove Gardners they were good for a mxiumum of 60 mph and that was only either downhill or after miles on the flat building up speed, look at a hill and they died.
Whereas with a 290 or higher 14 litre ■■■■■■■ you’d be up to 60 in no time and probably, as i was, cruising at 70 most of the time.
I’m quite sure that any Gardner able to keep up with a big cam ■■■■■■■ would have used just as much fuel.

I drove L10’s as well now and again and to be honest didn’t find them as economical as the 14 litre ■■■■■■■■ they were working all the time and never running easy.

Believe this or not, at around 38ton with a bulk tipper trailer 7 to 7.5 mpg was the norm with a 1984 build E320 14 litre ■■■■■■■ at a cruising speed of 70 @ 1100 rpm and that truck seldom ever needed a downchange on any motorway gradient, i once did an economy run, though admittedly much lighter load , and kept it to 55 mph which must have been around 900rpm and recorded 12.4 mpg.

Freely admit i hated Gardners as driver (of sorts :open_mouth: ), if the ones i’d driven had at least turned out reliable then that would have been something, once i got issued with ■■■■■■■ i then had trucks engines that were always on top of the job and simply, given decent servicing, always started instantly and never once let me down in literally millions of miles.
