Quick prop fitting question
Is it best to smear a small amount of something on the prop output shaft to ease the fitting into the gearbox oil seal ?
gearbox oil ?
grease ?
nothing ?
thanks

I would use a smear of gearbox oil.

Wipe a smear of gearbox oil round the lip with your finger...
...try hard not to mess up the two oilseal lips when you do insert the propshaft end.

Normal!
There should be a little trickle of oil into the chamber where the propshaft end fits over the splined shaft. There should be a seal at the very end
(as in this topic) that stops the oil dripping out once the prop is fitted.
If you tip the box back before fitting the prop then you should get a slow drip of oil - if not, there's a problem that needs fixing.

nice one david - a 'clever' mate said the box was knackered...
second point, do i fill it thru the top plate (type 9) near the front or thru the small lug hole on the side (if there is one) cos it seams easier to
do from the top. Is the level marker clear? i've lost loads since i first moved it all those decades ago...!

Any handy tip for not messing up the two oil seal lips ?
Because that seal was a bitch to change on account of the effort it took to remove the old one !!!

Joel,
I drilled a hole in the top plate and welded in a threaded boss - one of these days I'll put a dipstick in the brass plug!
giveme... just keep it oily, line it up carefully, and make sure that the end of the prop is nice and smooth where it enters.

The Sierra has a level plug the gear box should be filled through this to get the right level --- and the car should be level while you do it..Better
a fraction under filled than over -- over fill it and you will knacker the clutch.
With propshaft ou oil will leak out out, whel fitting the shaft clean off anny surface rust off the end and wipe with an oilly rag before fitting.
Changing oil type 9 oil seals is a 60 second job once the shaft is off, just hook it out wth a screw driver and tap the new one home using a large
socket as drft.

Forgot to mention why there's an 'oil leak' when the prop's out - as the rear axle goes over bumps it pushes the front end of
the prop in and out of the gearbox - the dribble of oil is to keep the splines lubricated. The oil seal stops the dribble going onto the floor!

Trouble is, you can't get at the level plug when the transmission tunnel's fitted! (Unless you drill a hole through the panel on the
passenger side - a real PITA to get at, as well). That's why I fitted a plug in the top.

Not mine the thing was stuck solid - completely destroyed the old seal getting it out. However found that an old piston from a sierra front brake
caliper was just right for drifting the new one in. Total time taken was about 20 mins !!! Not long but still longer than your 60 sec Britishtri
