Ok

A = B = 15.0mm
C = 6.9mm although not relevent really
D = 10.0mm
E = 145.0mm
F = 26.0mm althought not relevent really
G = 58.5mm
H = 86.5mm
I = 77mm although not relevent really

Overall width = 190mm
Thickness of tool = 19.5mm+

Only other bit not there is the diameter of the round quadrants, but that can be measured from the gearbox case.

Thanks Nutcase, This is a great help!
Thanks

I'll update my rebuild tomorrow with pics, but if people are looking to get a press for this job, especially pressing the rear pinion bearing off, get something bigger than a 6 ton one - it was right on the limit before the bearing started to move!

8790552 Stack height tool. 195.0mm - 195.1mm if using a depth tool. 900, 99?

Someone buy this before I decide to buy a spare

Usual disclaimer, not me selling

Would a 6-12" depth micrometer with a 6" foot be an acceptable substitute?

All you need is to weld a T, then cut it to a length of 195mm from the bottom of the "crossbar" to the bottom of the T.

Tried out my new and improved way of setting the pinion bearing preload. The block is bolted through not only the 40mm particleboard bench, but also through 25mm softwood underneath. The holes through the bench are sleeved with 2mm wall thickness stainless tube to spread the load out.



A reminder of how I used to have to do it - sitting on the floor, much much harder.

Great stash of inner drivers you have there nutcase.

[nutcase]

Some of them are quite heavily worn. When I've got enough, and there is demand, I'll get them refurbished.

How are you doing that? Flame welding and then reground?

[spg1]

Nutcase, the block you have bolted to the table, is that only saab or would a transmission shop have one of those? Im asking because the tools you have are, I would think, next to impossible to get.

[crwchf01]

Nutcase was fortunate enough to score some dealership tools. The block on the table is not the problem, but the fitting ring that is made to fit the pinion. Check your local auctions or older transmission shops that may want to sell seldom used tools.

I have absolutely no idea

The block is an adapter - probably simple to get made. As crwchf01 says, it's the rings that fit in the adapter that are hard to get (you can just see in the background a split one for the input shaft - couldn't find one anywhere so had to buy new. Not cheap

[S900t8v]

bought new from Saab?

[nutcase]

SPX who are the official distributor.
