Gearbox swap


Julian

Recommended Posts

I'm hopefully going to put my rebuilt gearbox in my Series 3 next week and I've got two questions so far:

1. Is it a good idea to replace the pilot bearing in the flywheel/crankshaft end?

2. Taking up the floors has been the normal struggle with rusted screws and spire nuts, does anyone do these items in stainless?

Cheers Julian.

Change the bush, change the release bearing, i might even go so far as to say change the rear crank seal while you're at it.

Stainless screws for the floor pans are all very well, but stainless and ali in the presence of saltwater* is a very bad combination. If you're going to use stainless fixings in ali you should really using nickel plated stainless. I have improved my 88 by putting the transmission tunnel on top of the floors, and by welding steel blocks to the diaphragm, so that the tunnel can be removed from the top, without removing the floors. When I rebuild the bulkhead, it will get blocks welded to it so that the floor pans are fitted similarly.

*you get the underside splashed with saltwater ever year, thanks to our wonderful highways department who insist on covering our roads with salt every winter.

Did a little more work today, floors, seat base, and roof off now so I can lift the GB out with my chain hoist and 'A' frame.

1. Will the gearbox come back far enough with the Fairey OD still on or should I remove it first?

2. Look at the state of this gearbox mount, look carefully and you can see it has a split in it due to it rusting right through - unbeliveable given how much oil these things leak!

I'm sure new ones are not available, has anyone got a good one they would like to sell me? Failing that I'll have to get some 1/8th plate and weld some patches on :-(

Cheers Julian.

gearbox will come out with overdrive still on, just remember, its only an ali casting though so try not to raunch it into the crossmember too much.

ej, im interested to know what you mean about the steel blocks? cant quite picture that, also i keep meaning to put my tunnel on top of my floors every time i take the bloody thing out, but never have the time to make sure its all watertight when done, so i keep "leaving it for now"

That's where you're going wrong - forget about watertightness, allow plenty of leakage then the water can run out faster than it can run in ;)

Its not a very good picture but its the only one I've got....

The red bit is the bit that bolts to the bulkhead, and now has a 30x6 block welded to the back of it. Then the cream bit is the bit that connects the first piece to the tunnel, which I put in place, drilled through, and tapped the steel block I'd welded on. You can see the welds at the bottom of the photo where the tunnel bolts to this bit.
