Just wondered what sort of height distance people get away with between gearbox and axle - having swapped the engine in my SWB Marlin I have quite a difference in height between the two, also as I have a long MG gear box, my propshaft will end up quite short which is not going to help the angle. I guess taking the lowering blocks out has also dropped the relative position of the axle. I have read all the theoretical stuff on the web, but wondered what peoples practical experience was. For those who have Marlins it would be interesting to know at what it is like on other cars.
I recall that Terry Coventry had this problem with his V8 Marlin and after destroying several UJs ended up using CV joints.
ReplyDeleteThey could fit these to any prop shaft I would have thought. QT
ReplyDeleteservices are good at this sort of thing in Devon.

Propshaft Clinic in Bradford offers them too - and I've always had good service/advice from them (the place, not the UJs as I've not got any of them). Problem might be diameter - UJs that will work at greater angles on Land Rovers etc seem to be larger diameter - so might not fit in your transmission tunnel. Don't foget the changing distance between axle and gearbox as the axle bounces up and down - dunno how a Marlin prop works, but on a Ford box, the prop slides in and out on a spline as the axle moves - you need a minimum amount of engagement to be sure of not breaking it, you could end up either dropping off the end, or binding up as the prop is jams against the end of the box. Dutton prop must be all of 18" long, but we get away with 8"+ of axle movement - full droop to full bump without signs of damage to the UJs - which is not something we could say about the original prop . ..
