Rebuilding a Type 9 box - how easy?
supercat - 10/3/08 at 02:13 PM

Hi Chaps,

Looking at rebuilding my gearbox as some of the seals are weeping and I'm sure it could do with some new bearings - is this a job that can be done reasonably easily at home? Any tips from anyone who has done it?

Cheers,
James

I had to replace the alloy rear casing on my type 9 once, what a pain in the back side that was. Loads of springs and pins, a real pig of a job. I'd leave it to the experts to overhaul unless you are very familiar with the construction on the type 9

Changing the oil seals is reasonably easy...

As the above postings.

Reasonably straight forward job to change the oil seals.

It all gets a lot more involved if you are going to start changing bearings.

You'll need a very clean area to work in, a photographic memory and the paitence of a saint

If components other than bearings are going to be required, it is likely to be an expensive overhaul.

I have overhauled a few boxes in the past. Its nice to know all is well.

The older Haynes book of lies for the Sierra covers gearbox rebuilds.

I was looking at this last night. My version seems to cover taking the whole thing apart but with no mention of oil seals.

Is it as simple as pulling them out of the ends and replacing?

The two end seals are easy to do, the back simply taps out, the other one up front also taps out once you've removed the 4 bolts and cover.
