This week started with a trip to Devon to relocate engine bits and a ton of other stuff that are cluttering up my garage and workshop at home.
I was planning to paint the body frame this week, but following 2 months of 30 degrees and me needing to be 200 miles away from the project it has done nothing but fucking piss down with rain.
Gearbox rebuild seemed like a stupid thing to concentrate my time on. There are companys who will provide a rebuild box but these jobs are way the wrong side of a bag of sand. How hard can it be and what is the worst that could happen?
The workshop manual makes reassuring noises like no special tools and in scope of home mechanic etc
The LT95 gearbox for the early Range Rover is a 4 speed (with synchromesh) unit. The box has an integral transferbox complete with high/low ratios and a centre differential.
The whole thing is fiendishly heavy. but it can be broken down pretty easily but some large sockets are needed
first step was to lob some racking on the bench, there is a lot of bits
Bellhousing comes off but the rest of the main casing is a single unit. I have already removed the oil pump at this point
with bellhousing and oil pump out of the way, the next thing to remove is the front bearing plate that supports the forwards end of the mainshaft and layshafts. On most gearboxes these are in constant mesh.
The mainshaft is still held in place by selector forks and also the transfer gear at the other end of it.
Here is the layshaft it comes as a big lump. The layshaft drives the oil pump at its forward end.
removing the gear selector plate exposes the gear select rods and folks.
Bottom rod is for 1st and 2nd gear selection. Middle rod is 3rd and 4th and the top rod with the spring gate is for reverse.
Next I need to work on the transfer box at back end of the box which is separated by a bulkhead inside the casing. Gearbox and Transferbox have their own oil supply.
Luckily there are loads of access holes on the casing. Here I am looking down on the centre diff and the transferbox intermediate gears, high and low ratio
This is the rear drivers side of the box, I have removed the difflock mechanism from the forward end of the transferbox that connects to the front propshaft.
And the rear speedo housing that supports the transmission brake and flange for the rear propshaft. at this point the centre diff unit can be pulled out.
to pull the gearbox mainshaft out I must first release this slip ring and pull the transfer gear from the end of the main shaft.
And that is pretty much the casing empty and ready for cleaning
