Broke my driveshaft

[GTR-240Z]

I managed to break a driveshaft at the pod today, thankfully a quick call to Steve and I'd managed to find a replacement cv so me and Matt borrowed Mike's car for a trip up to Pmac's to pick it up. Eventually got back to the pod and swapped out the shaft with the help of Tel in the pod car park.

So just wanted to thank Mike, Matt, Pmac, Steve, Tel and anybody else at the pod that help me today

And for those of you that want to see the buggered cv.

Fair play to all who helped out on this
Big kudos indeed to you all

So what's the next weak link ?

What type shaft was it from ?

What type shaft was it from ?

280ZX with Tripod CV type joints.

Darren your more than welcome, glad to be of (some) assistance

The problem is that these things are 30 years old and have sat underneath cars for those 30 years (loads of surface pitting, micro fractures, age brittleness)

Size wise they are more than adequate to support that sort of power but if the core metal isnt in good condition then it might as well be a straw

Maybe get the replacement set cut back, radiused, crack tested, cryo treated and powder coated.
Which will cost several hundred £ without the replacement shaft(s)

The alternative is to get a custom set up made

Shafts (Elite transmissions have a pattern from mine) £350-400
CV's (GKN) £50x4
Custom companion flanges £25 x 4
Boots n bolts £50

All in thats £750-800, fit and forget.....guaranteed to take even the power of a Samuri

Was great to see everyone getting together and helping you out Darren, that's a big part of what I feel being part of the club is all about.

I agree George it was a nice feeling that several club members got together and helped me get the car fixed so I could drive it home.

Think I will relook at my rear end setup (the car's not my own before anyone says) and will add it to my winter mod's and maintenance program.

Not enough power I definitely need more power


or prehaps some mechanical sympathy when launching

Bargain, group buy ?

I came across this which may be of interest, scroll down to the very bottom: Techno Toy Tuning - Your performance parts source for the old school cool!

It could be a bit too overkill so you may want to wait to hear what JMortensen comes up with on Hybridz, I know he's working on a stronger drive shaft solution.

I've always been a bit concerned by over engineering the drive shaft to prevent failure - in a way it's acting as a safety fuse. If it's too strong to break then something else down the line might, which may be more costly to fix or more dangerous when it fails. That's why I always keep a spare drive shaft in the back of the Z. Of course you can always strengthen all of the transmission components to engineer out failure.

Thanks for the link George. I'm already planning on a significant update in this area along with a load of other stuff I'm not happy with on the car. Going to be a busy autumn, winter, and spring I think.

4 bolt Z31 turbo? shafts seem to be the way to go
Getting them aswell as MM flanges seem more the prob?

Not at that time of night

Can't you repost it during the day

 

[GTR-240Z]

yeah agreed with 900ss I always enjoy your posts Steve so come on what did you post?

The Z31 CV's with Modern Motorsport flanges etc looks like a good setup. If you want to keep an R200. But I wonder what Z31 CV parts are like to obtain as Nissan seem to hold even less Z31 stuff than 240z's these days.

Currently I'm warming to these along with the custom shafts they supply

For costs, Z31 must be the easiest and safest ?
From what I've read I haven't seen any complaints/failures with them?
As said getting the parts ova ere is more the issue

One For Mr F?
Do the joints interchange/ share with other nissans?

 

[Wyn]

R200 diff
I take it the std 4 bolt diff output flange and inner hub flange of a 260 isnt the weak link ?
If not is there not a bolt on adaptor plate that allows cv shafts like these to be used?

Found a random pic lol
something like this x 2 per side

i wonder if these would be ok
