Gearbox rebuild

[Wyn]

S14a box sat in my shed if you want one

At least that's what I think it is ?

£45 as is, as it was noisy in gear so prob wants a few bearings

Could be ideal for youz Zee car

I will definitely consider these boxes guys, just need to find the other stuff if anyone can help wouldn't even know where to look?

is this any good ? http://www.swmotorsport.com.au/index.php?cPath=16_71&&page=3

thanks for all these replies guys, can anyone point me in the direction of where to get the drive shaft from? all the other bits i can sort out.

You've already got one! You need to have a standard Z driveshaft shortened by 50mm.

 

[Craig_260]

oh awesome thanks Rich no other mods to it apart from that?

 

[richiep]

It needs the dust cover that partially shrouds the yoke removing. It's only held on by a couple of spot welds. Otherwise the driveshaft will not insert fully into the s14 box.

If you've not seen it, this site has a good description of the process:

As mentioned before, contacting pmac from this site is a good idea. He may be able to provide you with the parts and advice you need (he and Skiddell have provided these as complete or partial kits). The bellhousing machining is quite critical and I hear not all machine shops are actually willing/able to tackle it properly. Luckily pmac has a specific arrangement with a machine shop who can do it. He also has a jig to modify the later gearbox crossmember properly.

As for driveshaft shortening, that should be easier to execute. I had a quote of 70 quid for a driveshaft specialist near me in Cheshire (Firow Propshafts) to shorten, remove yoke dust cover, balance, and paint.

dug up my old thread saves making another on same subject.

So I have my box now my next question while its out i may as well do the clutch is it just the Datsun clutch I need or do i need to frankenstein one out of an S13 one as well?

Can't help on the clutch but did pmac sort the machining out etc - always handy to know a few contacts for when things inevitably go wrong!

Just a datsun clutch. 2 sizes, for 225mm flywheel or 250mm flywheel.
