What's easier

[Jarvo88]

G'day guys I've got to do a clutch and was wondering what's easier
Motor out tb42s
Box out

Don't really have the room or height to make getting under easy
How hard is it to get the box out never done one before never pulled a motor out ether lol
Cheers guys

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
I have only seen it done on a hoist with a transmission jack.
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...

Ouch Jarvo , sounds like it might be better to pull the lot .

[Jarvo88]

That's what I was thinking pull it out the I can get to everything else a lot easier and I won't be under it the whole time lol

[dom14]

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?

When I had to replace a clutch in my TB42e and saw the size and guessed weight I let a pro handle it....24 hr turn around and no effort by me and I do most of my own work usually. I think about $700 all up including tranny service.

I'm obviously not paid well enough...

Wouldn't bother. It really isn't that difficult to put an engine back in if you take your time and go smoothly. Angle of the dangle.
The pilot shaft does have a taper to the spigot and to the splines (and equally, the pilot bearing and clutch plate splines are tapered...) so it will usually line itself up no drama.
