Has anyone got a diagram showing the dimensions to make a home made flange holder & puller for a 5-speed gearbox? Thanks :thumb2

I want to use the services of one of our contractors to have them fabbed up.

If you can get a dozen made I guess there will be a market here - depending on the price of course.

I'd be interested ih acquiring one.

I think there's a drawing on the www.powerboxer.de site.
Using that drawing I built myself a flange puller and it worked flawlessly.
Total cost was around 8 £s including four bolts with nonstandart threads and sizes (removed bolts are too short for that drawing).
But as I mentioned before on a previous thread, taking the gearbox to an auto mechanic is generally the most logical way (at least in Turkey).
Because other than the puller there are several things you should also have like a sturdy adapter to fix the gearbox to the bench and a strong helper (high forces are involved in disassembly and assembly - around 200nm).

Heres mine.

You can work out the dimensions from this. The stuby little handle clamps in a vice. Bolts are 8mm fine metric thread.

My "special" tools

A strip of 1/8"x1" steel two holes offset so you can get a socket on the output nut..long enough to clamp in a vice.

Old forged spanner with two holes drilled..used original bm bolts if I recall with a ball bearing 'twixt it and the shaft.

Worked fine on the R100GS before last. Heated the end cover with a camping stove and pulled it off. Looked in cringed put it back and sold the beast:D

cost £0...

This is what i made...You use the original bolts
Tighten them up like you were fitting the driveshaft... Sometimes the flange will pop off as you tighten the bolts
If not lift the gearbox just off the floor with the bar and hit the centre with a hammer the shock then removes the flange...Used it loads of times and it's never failed...Cost peanuts to make...Theres no need for a lot of these fancy expensive tools just a bit of injunuity
