Thread: Engine and/or gearbox changes in IIa (etc)

Yes; some of the fasteners that hold the transfer box on are inside the casing.

I put a nut behind the intermediate shaft and used a lever on it to push the shaft out in increments but that was on the workshop floor where it was easy to work on.

Removing the seatbox isn't that difficult and two blokes with a pole and straps can get both boxes out easily enough,

Cheers Charlie

You just need to drain the oil, drop the pan, unbolt the handbrake, then unbolt the lock tab which holds the intermediate shaft in place, then use a crowbar or tyre lever to remove the intermediate shaft and gear.

ok sounds a bit more straight forward. Thanks Charlie and Ben!

to get it out without pulling the engine the tetris is as follows

unbolt Tcase
remove Tcase
support gearbox on cross member
remove lower bell housing bolts
support engine/bell housing on cross member
remove all the bits from the bell housing and the shifter
unbolt bell housing from engine
pull backwards and down
pull back further lift up and slide forwards rotating as you go
lift gearbox and bell housing out through cab OR lower to ground and slide out from under vehicle.

IF your going to goto that much effort it is easier to pull the engine and Tcase ASSY out as a single unit by removing the seatbox. then reach in with the engine crane and pull the trans out through the door. If you dont have an engine crane or some really strong friends then split the Tcase off.

You will NOT get the 6cyl. engine out with the gearbox on.After reamoving manafolds altanator oil fillter dissy dipstick tube and anything else you can possably reamove, start removing body pannels.Yes it is that tight a fit!As for the gearbox it all depends how strong you and your back are,I always use an engine hoist through the inside with the seat box removed.Eric

I haven't removed the seat box in a LandRover for over 15 years, and have removed gearbox and transfercase as separate entitities in both 4 and 6 cyl vehicle dozens of times. If the gearbox is going to be overhauled, the transfercase need to come of anyway. The only differences, aside from the couple of hours saved from not removing and refitting the seat box, is that you'll be lying on your back while removing the transfer, and you'll be handling 2 relatively lightweight components instead of one heavy awkwardly unbalanced assembly.From memory 4cyl boxes came out from above, whilst 6cyl boxes came out from the bottom after rolling the box on its left side and removing the low range lever pivot bracket from the bell housing. This is for vehicles with non removable t/case crossmembers of course.

I am emotionally scarred after mating up my Holden to the LR GB (on the floor!!!) and am convinced it's next to impossible in-situ. I'm reluctant to proceed further with the resto till I sort this out to my satisfaction.

The 3rd crossmember holds the GB mounts & appears to be fairly minor in the scheme of things.

If it wasn't there, engine & GB should come out together easily: lift, push car back (my crane won't roll loaded due to a poor concrete floor), a bit of a tilt to clear the 2nd crossmember & "Robert's your father's brother!"

Can it be cut off, have brackets/cleats welded on and then bolted back in place? Has anyone done it??

what you want is a nice chunk of 8-12mm plywood and a sheet of metal or checker plate to put down.

My crane rolls fine on it and Im often using it on sand, grass and even mud.
