BEST 'ERGO' ?

kr79:
I remember reading years ago that the fixed head engine was reduced in size during the design to bring the weight under 1 ton. Dont know if theres any truth in it though.
Also that there was a high rejection rate on the production line but how many also slipped through the net.
So it could be poor tooling and casting that didnt help as it seems by all acounts you got one that was either super reliable or more likely one that [zb] it self on s regular basis.

There seems to be a difference in the reasoning given in some explanations compared to others for the capacity of the 500.IE some say it was all about space while others say it was all about weight. :confused:

It wouldn’t be surprising that ‘if’ it had been the case,that Leyland’s bean counters had been stupid enough to order just the downscaling of the 700,instead of ordering the designing a different smaller capacity fixed head engine,and then expected it to work,to have then had to think up an excuse quick to put the blame anywhere else but where it belonged when it inevitably didn’t work. :bulb: Which might be a possibility considering the documented reports that the thing was manufactured on new machinery which was purchased to do the job which would then make the excuse of so called out of tolerance machining less credible. :bulb:

It would also explain why Dr Fogg seems to have walked away because of his ‘issues’ concerning the use of the 500 engine design with no documented reports as to his exact reasoning for doing so.Especially if,to add insult to injury of using a too small engine capacity for it’s design aims,the beancounters then also effectively and erroneously butchered the 700 engine design,that he seems to have had faith in,to do it.All because of a bs weight saving crusade,let alone if it had been because Leyland needed something which would fit under the too small/low set ERGO cab. :open_mouth: :unamused:

However engineering logic says that there’s no way that the 500 could have had any connection with the 700 with both having had to have been two different engines.Which would have simply meant that the bean counters in control of Leyland chose the wrong option beween the two ideas possibly in view of the documented compromised engine space available with the ERGO cab.Then true to form tried to cover themselves by putting the blame elsewhere and using misinformation to change story of how it all happened from the outset.Especially if the whole thing had been the result of flawed thinking in following Mueller’s advice. :open_mouth: :unamused: :laughing:

As for the reliable 500’s v the grenades I’d bet that would have been a case of those that were used in the lighter weight applications running at a lot less than 32 t gross. :bulb:
