New Clutch Gearbox Removal And Refit

[grey pearl]

Hi There, I am new to posting on this site as registering proved positively frustrating, so I've been on the UK site as it was easier to get on, probably my computer skills lacking,Anyway I'm here now so I have this problem.

I have a GTR33 my first one,and everything was going fine until I decided to have a go at the skyline launch, just one, to see how fast it would do 0-100, 6000 and dropped the clutch, unfortunately I over ran the clutch in 1st and 2nd and that was alright but when I got home I had a look under the car and to my dismay found smurf blood all over my once pristine gearbox.

So after reading 114 pages of transmission and clutch problems on this forum I have a fair grip on the weaknesses of the drivetrains on these vehicles, and what parts to change etc.I rang Jim Berry and after a few long discussions have bought a replacement clutch suitable for up to approx 350 kw which I hope to achieve in the future.

Whilst doing my homework on the subject I ran across a company in Sydney called award gearboxes and after speaking extensively with Terry decided on upgrading my series 1 gearbox internals to the series 3 spec while I'm paying for the box to come out, replace the leaking seal,and upgrade the clutch.

The dillemma then was who to take my car to in Melbourne that would do a good job of remove and rebuild box and put it all back together without mistakes and without bending my new clutch fingers as often happens.I have looked everywhere on this site and have either missed, or can't find any lists of recommended workshops that could do all of this in house reliably and order all of the necessary parts for the box internal upgrade.

More than that I would like any supported recommendations from you people who know of such a place from your experiences to get me out of this headache,if you can't tell me openly on the site because of policy you can PM me,It would be much appreciated as my car hasn't moved out of the garage since the oil discovery as I don't want my flywheel getting any more oil than necessary on it as I wish to re-use it.

I would also like to share some reliable info I have gleaned about synchro's in gtr boxes that there seems to be confusion over on the postings I've seen on this forum. The redline shockproof oil only masks the notchiness in these gearboxes for a short time in most cases and not at all in others as in my case,the reason is that the redline oil is actually too effective and slippery to allow the sychro hubs to slow down The baulk ring or synchro to the right meshing speed for fast smooth changes, a certain amount of friction is required to achieve this so a more conventional oil like VMX80 allows this to happen properly whereas the ultra slippery smurf's blood doesn't.

Solution Either pull the box down and bead blast the sychro hubs to create the right amount of friction and use them again and use VMX80 or replace the hubs with new ones and use the more conventional oil to avoid the problem re-occurring prematurely again.Of course no gearbox lasts forever especially abused ones but just thought I would share that with those confused by the conflicting messages about oils and notchy gearchanges, any disagreement with this info can be overcome by speaking with Terry 0296380822.

I am expecting possible problems down the track if I ever get this work done, of my pedal box breaking from the 4000lb clamp pressure of the new clutch and wonder how to remove the existing pedal box to replace it if it breaks with a nismo one, are the Nismo ones bullet proof or do most of you just re-weld the stock one and have success with that.I'm not sure from what I've read as to whether the stock one suffers from not enough weld or the material being too thin, any info greatly appreciated.Also have any of you fixed them in the car without removal and what is the proceedure for getting them out??Cheers hope you can help me with all this and I hope to keep my posts shorter in future please forgive me this time as I have been struggling with these questions for some time and couldn't get to talk to you because of my registering problems.Grey Pearl out

There is a guy at Windsor called Stuart Wilkins that I have heard of....I haven't used him but have heard his name mentioned very positively a few times by different acquaintances of mine in Syd...He trades as Stuart Wilkins motorsport..I think they specialise in Datsun / Nissan racegear and rally prep and have done so for many years...At least give him a call...Dont have his number but Google should help you out...

If you are in Newcastle PM me and I will tell you who NOT to go with...

PS welcome to the forums...
