prop shaft - which way round for petrol?

Post by sonic23 »

I don't know if it really matters - but on a petrol syncro, should the rubber donut be at the front of the van or the back?
My old one was fitted to the front, and i seem to remember someone telling me it was the wrong way round for a petrol
cheers,
Rich

I think you meant to say, if you convert a petrol to diesel, well done for fitting an engine far more suitable to the Syncro :wink:

well the van doesnt seem to mind at all but i am sure that there must be some german logic in the difference between petrol and diesel prop shaft rubber placement.
i would love to know what it is.

i only converted my petrol van to diesel so that i could run it on vegetable oil. i know it isnt the final solution but it is a very viable stopgap when you have as many restaurants as we do around st ives.
i would do the other van too if i had the cash.
although next time i will choose an engine with a turbo and an intercooler. my doka is a bit slow.

Probably something as innocent as minimizing a possible source of driveline vibration? The 1.6 diesel is quite a rattler compared with its silky smooth petrol powered cousins; putting the flexible donut as far away from a source of vibration may have been considered a good thing ?

Well thats my feasible theory number 1; any more out there?

Yeah, what you really need in a low-geared vehicle is an engine with a limited rev range and narrow power band :rofl
I hate 4 pot diesels, they all rattle like an old taxi :wink:

Ok ok...If I hadn't wasted so much time sorting out that deal-gone-sour it would be fixed, so both it and I would have done a few muddy miles by now ...I was however very impressed by what can be achieved with a DG at syncropendence, courtesy of Si.
I still hate diesels and I found Dokas to be claustrophobic. Don't want one. :shock: There, I've said it.
