A Land Rover gearbox and transfer box is a big lump to deal with. It’s heavy and will not sit on the bench without rolling around. If you have a spare gearbox it tends to sit on the floor in the corner of the workshop and get slid around wearing out the sump plug among other bits underneath.
I have made up a frame to solve all above (actually I have three now). It is easy to make and saves a lot of time and maybe injury. It is a couple of bits of box section and two bits of flat stock suitably drilled and bent (hit with a big hammer in the vice, what my Dad called “Cold smithing”) then welded together. It bolts onto the transfer box mountings and allows you to remove all the other parts in man sized lumps. If you turn it on end it makes re-fitting the bell housing much easier. With a block of wood it will sit on its side.
Best of all, it will not roll off the bench and land on your foot.
I have also made up a lifting frame out of a couple of bits of steel and some chain. It hold the ‘box in the correct attitude for refitting in the vehicle. The angle iron at the front will need a bit go “sculpturing” with the angle grinder and you may need to replace the bolts at the front with studs (easily obtainable from Craddock’s/Paddock as the gearbox is covered in them and they only cost pennies).
The thing bolted to the front output flange is my universal stopping-things-going-round tool. Again, well worth the effort.
