leaking gearbox

Post by jon parker » Fri Jun 22, 2018 1:25 pm

I have finally decided to do something about the pool of oil under the gearbox. Changed the input shaft seal (optimistic). Gearbox still leaks I guess it must be the seals by the axles and differential. Question: do I have to drop the gearbox in order to change them or is there another way? Is it worth changing the gaiters to see if that does it first?
thank you thank you Jon

Hi Jon

What gearbox are you running - IRS or split ?

If it’s IRS you can change the output shaft seals in situ. Not sure on a split, but someone will be along shortly.

Thinks it’s a big job though if split, depending on the leak origin.

Cheers

Jonny

I've got a split with standard trailing arm,
Thought it sounded too good somehow. Thanks for your reply.

It’s probably the axle tube gaiters. Notorious leak spot, especially if they are the split type with a row of small bolts along a seam. Mine ...... out took multiple attempts to stop it, but have finally cured it now.

Take it to your local petrol station that has a jet washer. Give the gearbox and engine a real good blast.

Then watch for new leaks. When it's filty you'll never tell where its coming from.

Could be gaiters that need reseating or they could be perished and need replacing.

But also very common for the output flange covers to be leaking past the gaskets.

Its possible to do both with the gearbox installed, PITA but possible.

The manual description details the procedure for setting the gasket thickness.
