Thanks, I searched for "books" and got the "fact or fiction" group, and "Scriminger" produced nothing. It didn't occur to me to check under my model number.

Nice to know they're also available on kindle.

The books are listed on Motobins, cunningly hidden behind the menu item "books"

I don't remember needing my press to get the gears off just a regular mechanical gear puller the the bearing separator set I got from Harbor Freight.  If I was home I have detailed step-by-step pictures of the disassembly and assembly.

I can't find the Scriminger books on motobins.co.uk: is there a better place to look?

Hmm. My take is that if you need a 50t press to get a gear off the shaft that its internal condition is still as good as the day it was put on the shaft. What is relevant is the condition of the working faces of the gear a d they can be inspected without removal.

There is something that cost me a lot of money till a penny dropped - shims.

I spent a fortune on shims from BMW until I realized they are standard engineering shims. I bought 15 dollars worth at a supply company and I reckon that will be a lifetime supply

No I do not disagree at all.

The seperator/puller in the link you posted will change the bearings l, you will only run into trouble if you need to change the layshaft, some of the gears are a very stern interference fit.

But, to change bearings you will be just fine with the tool you have.
Thanks Tony,
And that bothers me. Because I would like to disassemble all 3 shafts to check and verify everything.
And I do not know anyone near me having a 50T press....

Yes, Justin, I've got the tools to remove the coupling and a sturdy bar to hold the transmission and lock it hard on the bench. Including the propane torch.
All I miss is a way to remove the old bearings, dismantle the shafts and reassemble them back. I thought an hydraulic puller (10 Ton) was sufficient but Tony disagree.....

It's been a long time since I rebuilt one but I don't remember using my press.  What Tony mentioned jogged some grey matter so I think that is how I did it.  You will need to make a tool for removing the nut that secures the front driveshaft yoke to the output shaft.  I also drilled a couple of holes in some angle stock and bolted it to the trans then in the vise.

I would post up some pics but I'm up in the mountains far away from me picture repository.
