Gtr gearbox install

[boomtheroom]

Right So got my s3 r33 gtr gearbox to go into my 89 r32 gtr

Gotta do the pull to push conversion...so means draining the oil in the box to take the front plate off ,my understanding is the oil in the box currently is just a small amount of storage oil?

is that the case?

if so is it safe to refill the oil out of the box with the permanent stuff before attaching the transfer case  and getting it on the car or is there a good chance some will spill out the back

during this process? anyone done it this way?

Cheers!

Do you really want to go push clutch?

Would it not be easier to just drill and tap for the pull clutch on the R33 belhousing and use the bits you need from the R32?

Would it not be better to go all modern and concentric, if not wanting to retrofit pull clutch?

Sorry.. I meant push to pull conversion… 🙄

And me sorry too, because I followed your lead with brain switched off and I also actually meant "do you really want to go pull clutch?" So my 1st post should look like:

you got confused by you comment then brain fart happened 😄

[boomtheroom]

so... yeah ..any disadvantage of refilling the gearbox before attaching the transfer case  and putting back on the car?

can it possibly  come out the rear of the gearbox if tilted too far back?

[GTSBoy]

I wouldn't bother. Filling a gearbox is pretty easy when it's installed. Just use a squeeze bag, or a small pumpy pump.

Fit transfer to box first before fluids.

Not really sure of the order you are thinking, but you need front plate with chosen clutch pivot and xfer case on before you fit it in the car.

Yes you can fill the gearbox and transfer case before you install it, and no you won't lose any (or much) oil if you do it that way

If swapping pull to push, remember the Threebond not threadlocker on the input shaft front cover bottom 3 bolts when refitting, or else it will leak.

You can use either of the above but preferred is 1207C - the red / brown stuff as it is anti sag, cures faster, has higher temp rating and a superior oil resistance to the ones mentioned. Same stuff used on an RB26 sump.

Never used that CRC one but "appears" to be the 1207C equivalent. Threebond is actually what Nissan sells as their factory RTV from Japan (sourced from Australia).

Some people still use the 1215 grey as it cures slower on sumps, which gives more time when stuffing around fitting it - but it is definitely not as high temp or as oil resistant.

Took one bolt out looks like threadloc more than anything else was chalky to touch..

 

[boomtheroom]

Btw Anyone know what the torque settings are for these cant find anything in the workshop manual...

[BK]

Look harder, it's there. 15 - 20Nm something like that. Seriously though just use a 3/8 drive and tighten it moderately. The sealant on those lower bolts are definitely more important than the exact torque settings.

[Duncan]

CH-88 in the manual

[BK]

Transfer case to box torque settings yes, but below was referring to gearbox input shaft front cover

I'm sure Duncan will have that page handy for exact torque 👍

[Duncan]

No, sure enough p CH-54 mentions the sealant on the 3 bolts but no torque settings.

It is listed on SD-11 though
