Thread: MT82 Adaptor shaft replacement - tools, tips and tricks

I'm about to attempt to swap out my Ashcroft MT82 adaptor shaft (blue version) for a LOF one piece (and seals on both gbox and tc). The gearbox has dumped all its oil and I've been told its likely the Ashcroft seals. Could be a blocked breather etc - plan to check, but I have the one piece LOF adaptor shaft now so might as well do all at once.

Few queries:

1. As far as I can tell will most likely need a slide hammer (get the male to male part out) + a bearing puller (get the female part off the gearbox shaft)?
2. Without the Ashcroft special tool how hard is it going to be to unscrew the oil chamber? Can I just chisel it with a screwdriver (not worried about damaging it)
3. Is there anyone in Sydney with any of the above three tools I could loan off them over a weekend for a slab of beer?

Any other tips and tricks for the job would be much appreciated.

Cheers,
Gus

I bought this tool @ TradeTools and it did do the job surprisingly. The previous owner/mechanic must have used too much locktite as we had to use an pipe extension on the end of the tool to get the leverage to loosen the female component.

Or something to get the male-male coupling out? - https://res.cloudinary.com/rsc/image...24/F0237754-01 ?

Will grab one of those.

Yes, one of those puller types should do the job…

For what its worth LOF shaft has caused no issues for me.
Good luck with your conversion

I had thought I've posted some of these pics and info here before...

Some other mods etc to do while you have it apart...
The diff lock lever (the long one in the pic) pivots on a rubbish bitey washer, remove the rod, thread it, thin down the white nylon spacer and put a nyloc on it, tight, as it wears over the years, tighten it up as needed.

Back of the transfer case, the centre shaft that the nut in the pic is on is often loose from factory as it has not been staked enough, remove it, tap the shaft out a bit, on the other side clean it up, put a good quality sealant, tap it back, tighten nut, stake correctly.

add 2 collars to the diagnal bolts on the top shift assembly

Thanks Dazza - these are great tips as well as the tools above. Appreciate your taking the time.

Had meant to do the shift assembly collars but never got round to it.

Also - do you think short of tracking down your little transfer case input shaft wrench doo-dad - chucking the box in 6th on chocked wheels should be enough to loosen off the Ashcroft? I have a puller (that I hope is up to the task) + the C Hook wrench now thanks to Robmacca
