All, need to reseal my Getrag as it is leaking from the case halves, also looks as if it was resealed previously. Did some searching and can't find a manual or diy anywhere. Does anyone know where to find a manual for our transmission, or a good DIY to pull the case apart?

Interesting story. A new mechanic at my go-to garage (old school shop that rebuilds anything from prewar to classic Porsches and Ferraris) told me he refurbished plenty BMW Getrag boxes. I told him that apparently it is very difficult to refurbish the Getrag 260 265 280 etc. He told me this is true but not for him as he has been doing it for over 15 years. He even showed me a Getrag box he just finished working on for an E28 535i with massive Turbocharged M30 engine.

What I will do is hand him my broken Getrag 280 spare to see if he can get it done. If so I will report back. Also I can already tell the M5 community that it will be much much cheaper than the 5K BMW is asking for a new box.

Would love it if someone had the specs for these, to know what the clearances are supposed to be.

For my toyota boxes they have the manuals available and all info, easy enough to follow.

Might have to find the mk4 supra manual and see if the getrag v160 overhaul is covered in that.

Reason being is that my 280's shifter shakes around in 4th unless I hold it further into the gate.

OP it shouldn't be too difficult to separate the case.
It needs a specific type of fitting for the puller but this shouldn't be beyond a good gearbox shop, particularly if, like Hugo's, they have done others.
The really tough bit is getting 5th gear off the shaft which requires something like 12 tons of force.
If it won't budge, either the puller or 5th gear breaks.
I don't think you need to do this if you're only resealing.

Here are some links I gathered from this forum whilst rebuilding mine:

This is the front case installing 23 1 000 set:

We used a toledo hydraulic puller kit to do my Toyota fwd e58 transaxle. For that we had to modify some other pullers to make them fit.

I'd be interested to have a go at the 280, to try and see why the shifter shakes around.

Ubersaloon, I'd say it is the one you are thinking of, #GA25266, because there's about 7k of receipts for what I'd consider a botched rebuild job lol.

I've had all the linkages refreshed including installing a UUC Evo3 (kept standard hight) with DSSR and it tightened it up but no dice on the vibrations.

There was also small chunk of a gear tooth attached to the magnet when the mechanics changed the oil years ago..

Resealing the box is not hard at all - however reinstalling the front case is a bit iffy without that front case tool. I'm going to make myself one of those. I've already made a nice stand to hold the transmision a la transmission case holder.

I have a spare gearbox in the garage I would like to rebuild fully i.a.w. the construction group manual. I want to hire this puller for the dreaded 5th gear... Giant Puller

Nice.
According to the specialist I used, there isn't enough room around 5th gear to properly seat a 3 leg puller so the 12 tons has to go via only 2 legs.
End result is above.

you might be right - hard to tell exact dimensions from the image. Either way I need to re-seal that box so I'll pull it apart up to the point of removing 5th... then have a look/measure.

here it is getting pulled from teh shaft using the factory tool:

Nope, no chance of getting a bearing splitter in there. The mesh with the layshaft prevents that.

Here's a decent photo of it. sorry about the poor lighting:

yeah i reckon so too. you could even make up a 6-10mm thick load spreader which would fit over the cog so the legs don't apply massive local pressure. Snapping a puller.. oh well. snapping off some teeth = disaster.

I've heard the same thing - that the current batch of rings are quite out-of-round. I did a partial rebuild last years. New input, output and layshaft bearings. Did not disassemble the gear-set though.

Mine was rebuilt in 2016-17 but I re-used the synchros.
I had 2 sets to choose from - one from the original box which was shifting fine, just very noisy, and one from a spare box which the specialist said were also good.
I don't recall which ones he used in the end but I have spares if you don't want to risk using new ones.
