Today I finally went to the guy who's helping me getting the Getrag rebuild. He's actually an old colleague of PieterVN :)
We had a bit of trouble splitting the cases, turns out we forgot to put the trans in neutral. (I was probably asking to many questions lol).
However in the end we got it split. (When doing it the correct way, all of the gears/shafts stay in the rear housing.)
This is the worst mating surface of a syncro ring the transmission has (this is on the input shaft, 4th gear if I recall correctly)
However, it's still fine and will be reused again
I do have some wear on the selector shaft, there is a little roller that's pushed against this shaft and it's worn in a bit. The selector shaft is quite expensive so I suggested I might be able to laser weld and rework the shaft.
(By laser welding you can also weld + add hard material)
Parts..
Housings got put into a washing machine, however I will also glass bead blast them like I did on my transfer case + apply the ceramic coating.
Overall we spend 3,5 hours disassembling the trans, pulling of the gears and syncro's from the main shaft were the hardest part as they were really stuck on there!
I'll be buying new bearings or the input output and idle shaft. needle bearings for the gears won't be changed as he explained these don't see a lot of rotations.
After getting home, I went to the workshop. as I'm getting the bolts plated for the Getrag, I decided to also disassemble the alternator and steering pump to get some more parts to plate, to make it worth while.
Alternator looks a big old, but still works fine.
And disassembled! rear bearing is definitely shot, I'm guessing that's the reason why I got some humming noise coming from the engine
I'll also replace the voltage regulator as it's pretty cheap anyway
Are there specs for the minimum diameter of the commutator? I'll probably get it resurfaced if not as it's pretty grooved
Also needed to find out if I got a Vickers or Lemforder pump, it's a Vickers!
Can't wait to get these bead blasted, will be quite the difference
I already started the disassembly but got stuck on the rear half, not sure how to get it further disassembled
Trying to be as organized as possible, I'll print this picture and when it's time to assemble I only need to put the correct bolts-screws on the same place.
A little empty.. I also want to remove the engine mounts as I need to replace these when doing the X3 rack swap. the alu mounts will also get coated and bolts plated!
