Veilside R33

Transmission disassembly issue R32

Recommended Posts

Hey guys,

Nearing the final stages of stripping my R32GTR transmission before blasting and powder coat (then new gearbox).

Mostof the hard work is done, but I’m stuck getting the casing separated from the gears (bell housing is already off).

See pics below - basically the 2 metal pieces which attach to/form part of the shifting mech are stopping me from sliding the gears out in both directions as they’re hitting the housing.

I can’t work out how to remove them so the gears can be removed. Anyone have experience doing this? It looks like there might be pins through them, but not sure if that’s unrelated.

Thanks,

Andrew.

Yeah you need to remove the roll pin that holds the shifter receiver onto the rail. Bonus points if you don't knock the pin into the transfer case and never see it again

That's where the roll pin proof rag (and grease) comes into play.

Awesome! That was my suspicion. Got the one facing the bell housing out using a skinny drill bit and tapping it with a hammer.

Rear facing one isn’t having any of it though. Persistence?
 

Any other major hurdles you’re aware of for the rest of the tear down?

you really need an appropriately sized pin punch and a bigger hammer

Got them out! Thanks guys.

Any thoughts on removing this unit?

Have all the 12mm’s out. Now looks like there’s a large central hex bolt and 2 star shaped bolts to go, if I’m right. Don’t have either of those bits unfortunately.

@Duncan @GTSBoy and one final question. I think my skills may have now outrun the requirement.

I need to remove the part circled in blue (for powdercoating) and it seems to me that the way to do that probably requires a bunch of bearings (in the red area) will need to be pulled. Does that sound right?

might be time to admit defeat and take it to the mechanic.

Yes, absolutely. The centreplate is the main structural part of the gearbox. Everything is assembled onto it. If you want to powdercoat it, you have no option but for a complete disassembly of the clusters from it.

I applaud you for having a go, but, Mate, you are so far out of your depth it's not funny. If you are having trouble disassembling a transfer case, you have absolutely no hope of disassembling the Gearset from the centre plate, let alone reassembling it correctly.

Seriously before you stuff something up, put the tools down now and take it to a gearbox place please.

Are you really doing all of this just for powder coating ? Just sandblasting the cases looks heaps better and is more practical. And cheaper.

Taking to a recommended transmission specialist today. It all needs to come apart anyway as the gears will be replaced with either a Getrag or PPG box. Agree that sandblasting looks good, but for the level of build we're doing it needs to be coated. The entire underbody (subframes, arms, diff, etc) has been stripped and will be coated while the car's on the rotisserie for paint.

Sounds like a it's going to be a big dollar show car ?

Big dollar, yes (unfortunately). Show car, no. But will look clean and the goal is an 8 second pass in street trim.... meaning it may be an completely different box altogether in the end, anyway.

So I guess "show quality" street drag then. Sequential or auto in the end I guess. 8's is a tall order with a H pattern.

Sounds like a full on chassis up build, can't wait to see it. You got a build thread for it ? Sounds interesting....
