Propshaft fitting

I've had a search and can't find any posts about propshaft fitting.

What's the best way to put it on? I seem to remember there is an optimum distance from the gearbox for it to be positioned?

To put it on, drop the gear-box front beam to body down but don't remove the nuts, slide the prop as far as it will go to the clutch shaft end, and then locate the gearbox end of the prop. Tighten up the gearbox nuts, and then check the prop can still slide freely back and forth. If it doesn't, re-alignment of the engine mounts is needed most likely.

Most of that was from HAYNES, method worked for me. :D

As far as position goes, I remember Chris saying it should be 1mm or so of spline showing at gearbox end.

Yup, slide it on at the front, then back it a *long* way back. Me and Adam have always gone for about 1mm of splines, which means it's pretty tight up to the gearbox casing and neither of us has had spline failure.

I wouldn't undo the box, if you havn't undone it it won't have moved.

Cheers for that. I've got it on but unfortunately the splines on this clutch shaft are too stiff to see if it slides freely, even with a bit of WD40 on them. Should the engine mounts all be at the bottom of the travel in their slots?

Rear engine mounts had to be at the bottom of slots for me, for the lasers to point in the right place. Do you have Dai's front poly mounts? If so, they need shimming.

I've never managed a slidey propshaft, maybe that's saying something. It's a very light grip though, baby taps move it.

I do have Dai's mounts on the front, forgot they were too short! Is it a 3mm shim they need?

I managed to get the prop to move by just tugging on it, unfortunately it looks like whoever had this prop before installed (or most likely removed it) by hitting the end with a hammer. It definitely used to slide back and forth nicely for me on the old 1.4 clutch shaft, the splines on that were probably a bit knackered and too loose :)

Yup, 3mm shim!
