Factory Rb20det 5 Speed Gearbox Cefiro

[adrnln]

HI all as topics

Are the FACTORY 5 speed RB20DET gearbox's, fork, pivot ball, the same as all other RB20DET R32 gearbox's

I have a 5 speed manual Factory build Cefiro and have blown up my gearbox and have just ordered and received a RB20DET from a R32 after many many issues (clutch and other ) I have put the gearbox in and found that I don't have the full reach of my clutch and is bearly driveable ( grindes nearly every gear)

Clutch master and slave are brand new but still unable to get any pressure to my clutch and seems I am unable to fully disengage the clutch hence the grinding.

I have asked around and people seem to think that either the fork, throw bearing, bell housing or all the above are different from FACTORY 5 speed RB20DET Cefiro to the RB20DET R32 Skyline.

PLEASE help

ive got a r32 box in my ceff which seems to be ok. they both look the same.

ive had probs with aftermarket slaves pushrod being too short by 5-10mm!!

How did you fix the problem??

Ok put a longer pushrod and still not fixed

Now have been told to try change my gearbox oil to a 15 40

lets see what this does

i fixed it like you tried,by making a longer pushrod.

changing the box oil wont fix it.

sounds like air in the line,you did bleed the air out of the system?

Have had a made look into it for me and have now found the real problem. No sprigot bush!! BUT in saying this the last box I took out didnt have one aswell but still worked fine.

Having a auto engine put in after I blew the previous one up sprigot bush was never put in but did not seem to effect the driving of the gearbox/engine??

Go figure

Well getting one during the week and will let you know how it went

There is a difference in 5th gear. The ceffy box has a taller 5th gear being a 'family car'

the problem is the thrust bearing carrier. use your old carrier.

Hmmmmm

seems to all work ok for now.

will assess when I next pull the box out cause we all know its enevitable
