As above, gtir crank has larger flywheel bolts. If you use a de or det crank from an s body you will need to use the matching flywheel. Clutch is the same throughout all det's though.

That's great advice chaps, I'll definitely be asking for the exact part number.
Cheers

if you want to save a few quid I have got a very good crank here that I may sell but there not cheap as hard to get hold of crack free

Very good of you as there hard to come by these days

Bit of a lull this weekend as i'm waiting for the engineering co. to pull their finger out with the block, head etc  
So as stared at where the engine was and scratched my arse for a bit and noticed a leak coming out the gearbox/tranny joint.  


So its been decided for me, the tranny has to come off.
Could anyone give me some advice please;    
The tranny and gearbox dont share oil right, as they are completely seperate assemblies?
Is it simply a case of removing the n/s drive shaft and unbolting rear prop shaft and sliding out?

I tried to drain the tranny oil, is this the right plug because b'jesus it will not fuckin budge!


Also one of my jobs is to treat the front x-member, does this simply unbolt?

Its all been happening this week.

just bought new CP 86.5 piston kits plus all my rebuild parts from Erics. Hopefully have them before Christmas.
I've also dropped the gearbox/tranny assembly and split them ready to stripped and refurbished.

Can you buy gearbox rebuild kits? Eg new bearings, seals etc?  

Some from Nissan some are no longer availible but most bearing places should be able to match them

Yeah, ill strip it down and make a list of the real bearing and seal numbers shown on the parts, then i can buy the whole lot from anywhere. The Nissan part numbers wont mean anything to anyone outside Nissan and like you say are probably not available.

Has anyone written these part numbers down before? If so it would be quite a useful thing to have.

Nissan still do bearings & it only 2 nachi ones that you ideally want from nissan as all others can be exact match/make sourced from any decent bearing supplier. seals can be sourced from bearing suppliers etc but prefer nissan if budget allows, especially so for input shaft seal .

Like you say if you get any numbers for both bearings and seals please list them. Is there a diagram with all part numbers on that Nissan page ?

gearbox/transfer box diagram with all seals marked in red is in another thread, I'll list gearbox bearings & a diagram when get some free time .

You have been quiet lately Mr B

^ lol, missing you too woody, just busy, working away from home too which sucks .

Bet wrapping all those pressies is hard work and the north pole is realy cold huh

Got the gearbox stripped and ready to inspect.
Bit of a pain removing the shift rails but all sorted now,


Theres signs of moderate micro-pitting on all flanks as you would expect on a 100k gtir but not enough to cause macro-pitting or spalling that would generate whine. The gear roots were all manufactured to have full fillets and were shot peened and look great, no cracks or signs of interference.
Ill check the floats and baulk ring thickness next but the gearbox is looking shit loads better then the block did.

Just measured the float and baulk ring wear (clearances)
All in spec except 2nd gear which has 3x float and zero clearance.


Can anyone confirm if 2nd gear is dual cone?
In the workshop manual the exploded view shows only a single, but further into the manual it sshiws 2nd gear has both inner and outer cones?
I suppose ill find out soon enough once i pull the bearings off and slide the synchro off.

2nd and 3rd are dual cone after all

want me to make your day Neil?

That gearbox you have there is worth more money than you paid for your entire car you lucky bugger

Heres a pic of stock gearset, note the straighter cut gears in yours and the larger teeth where as stock are helical cut gears. Looks like a quaife gearset to me
Made your day haven't I lol

Oh my days lol so he has. Thats a sweet find..

That's awesome, go have a beer and celebrate, Christmas has come early

Well bugger me
I thought quaife were all spur gears (0 helix), so with these having some helix to them i thought they were stock.
Well, well, happy days, Christmas has come a bit early
Ho, ho, ho
