I admire your enthusiasm, it's something I probably wouldn't have a go at .

Very very heavy,, after all they are out of a truck

But very very heavy take care

Box out would be better, not so easy but there's fair bit of work in taking bits of off to get the the motor out then putting it all back. Need to make sure it's supported well with jacks or think it can be done through the cab with crane through the transmission tunnel.

I used ratchet tiedowns to remove gearboxes on my cabstar.
Used them as slings from the chassis rails. Took tiedown out of ratchet, fed end over one rail, then under gearbox, over other rail, put end back into ratchet, connected hooks together and put a bit of duct tape around hooks as a safety measure.
Had 2 slings at front between bellhousing and gearbox, and 2 slings at back of gearbox. Tighten 1 sling in each pair up to gearbox, other slings just a little looser. Undo gearbox and propshafts etc, pull gearbox back on slings, release 2 tiedown holding weight until next tiedowns take weight. Repeat alternating slings until gearbox on ground or if only doing clutch down and back enough to do the job.
Reverse proceedure to lift gearbox, slings also help in lining gearbox up as you can change front and rear height to get angle right.
Tip 1.. leave gearbox in gear before you undo it. You can then turn output flange to rotate the splines to line up with clutchplate.
Tip 2... get some longer bolts(about 25mm longer)for the bellhousing. Use about 4 of these when reinstalling gearbox, it makes lining up easier when there is still a 50mm gap between bellhousing and engine. Tighten these up lightly until you feel some resistance, rotate the gearbox output flange until the splines on the clutch engage ( the flange should stop moving when they lock in). Tighten the bolts up a little more. Fit the slave cylinder and operate the clutch. This will release the pressure plate and align the driven plate. The gearbox should then be able to pushed all the way home. Fit remaining bolts and replace longer bolts with originals.

Cheers for the advice Turtle_au only reason pulling the motor came about was due to the previous owner swapped motors and converted it to gas him self so now having to pull the old gas kit out wires are all over the joint all heater hoses need to replaced and he's stripped the threads on the exhaust manifold and inlet both mounts need to be changed and think it's done the rear main seal...

Yeah, it's easier to all those work on the engine while it's out of the engine bay, I reckon.
Heavy job for sure. Good engine crane is all you need.

This seems like a good tip except that I didn't understand it, LOL.
Anyone that knows how to do it would be so kind to explain?
