Oddly enough, I don’t ever remember breaking down in the middle of nowhere, despite the massive distances we covered.
We did take maintenance seriously. I regularly cleaned out the oil bath air filter on the Scania 110. I could never believe how much desert would be in there! I’m sure a few days worth of that would have ruined the engine.
I remember finishing early one night close to an Oasis, up near Hail. For some reason, I decided that the engine was about to pack up and decided to finish for the night, just as it was going dark. It went dark very quickly at those latitudes, unlike in England, there was simply no twilight - perhaps 10 minutes (maybe longer, it’s a long time ago!) between light and dark. When I looked at the engine, the turbocharger was glowing red, something I’d never seen before!
The next morning, the sun was up and attacking by 6 am. I made a cup of tea and set off. The Scania didn’t break down. In fact - apart from a clutch problem made worse by myself, using tipper oil instead of brake fluid - it never did!
Heading back from Jeddah to Dammam, going up Taif, in the Saviem, I became aware of a high note ‘tic, tic, tic’ sound. Not something in my personal experience, but from previous discussions it sounded like a little end. Still 900 miles back to base, but I decided to let it develop!
The Saviem got me back to Dammam. Sure enough, that’s what it was. The ‘MAN’ garage in Dammam replaced it and I was back on the road.
As said before, the Saviem was not up to the hot summers of Arabia. The temperature gauge would shoot up after about 10 am and low or high fifth on the ZF splitter would be the highest you could go without going into the red.
Pat Conway said that the 1418 merc was the same - the Merc had a buzzer. Pat would change down as soon as the buzzer sounded. One of the other drivers on the same run (Toyota pickups from Dammam to Riyadh) said ‘that buzzer gets on your ■■■■ after a couple of hours doesn’t it!’ Pat was appalled, he changed down and slowed down, but hey, the Merc never seized up!
John.
