Gearbox rear oil seal
Before i refit the prop, i figured may as well re-new the g/box rear oil seal that it slides through. Is removal of the old one a standard practice - it just pulls out? ( Auto box,prop removed).

Re: Gearbox rear oil seal
I've just replaced the rear seal on the auto box on my PI - just use a long thin screwdriver to lever it out. Make sure that tip of the blade is in the middle of the seal by the spring to ensure that you don't score the alloy whilst levering it out. It pops out quite easily once its moving. Use an appropriate sized socket to gently tap the new one in making sure its square before going at it too much! Alternatively, remove the spring on the old rubber seal, turn it round and then place a suitable socket in the groove and use it as a drift.

Re: Gearbox rear oil seal
They are commonly available at most places, but CW is generally considered on here as one of the better suppliers.
There are two types, the later rubber type with the tensioning spring, or the earlier type in which the seal is held in a metal surround. I used the later rubber type on my PI, as it was the same as the old one I was replacing.

Re: Gearbox rear oil seal
It's a good idea to pack the back of the seal with vaseline before you fit it, otherwise sometimes the knocking to fit the seal is enough to dislodge the spring out of the seal.

Re: Gearbox rear oil seal
Hi all I have a Triumph 2000 Mk1 engine and auto box in my 1948 Triumph Roadster. The rear seal is leaking and I want to know that if i can't pop the seal out as per suggestions below can I separate the extension housing in situ to gain access to the back of the seal . I would replace the extension housing gasket on reassembly.
I checked the Haynes manual for the Triumph 2000 and I think its possible but would like your comments please.
PS existing seal looks like it has a metal casing and the replacement from Rimmers is all rubber . I assume the spring is bonded in the lip of the seal as its not visible

Re: Gearbox rear oil seal
If you have enough room behind the box to be able to remove the tailshaft housing then I can't see why you would have problems removing the seal in-situ, but should the need arise the tailshaft housing can be removed without any problems. I can't be sure you'll be able to get at the back of the seal though as I've never tried it, but I would think you could, it just seems like a lot of work for nothing. You may want to remove the speedo driven gear first if you remove the housing, but I never have.

Re: Gearbox rear oil seal
I 'm not as experienced as 'harvey', but on the ones I have done, the rear seal pops out quite easily with the assistance of a long thin screwdriver. As said previously, just be careful that you don't score the alloy casing where the seal sits with the tip of the screwdriver whilst prising the seal out.

Re: Gearbox rear oil seal
Seal popped out real easy as stated above so thanks for that. I was a tad concerned that the splined shaft sticking out past might of made it awkward to get a proper purchase on it but was fine.
Incidently mine has a metal outer casing and oddly enough it looks as if there are a couple of flat spots on it where it has been rubbing. The housing is fine.
Bruce - i initially thought my seal had no spring but it is there - you have to turn it just enough to be able to view it sat against the inner wall.
