Drive shaft length

[macdeb]

Guys, does anyone know the length of the drive shafts please? as I want to upgrade them before the inevitable happens. Ideally I want to get them ordered and delivered so I can swap over weekend rather than take them off, measure then have to wait a couple of weeks for delivery.
cheers.

I have a pair of driveshafts from a BTR car and access to a gkn rolling chassis so can measure both types if required.
Will do it this afternoon.

sorry OP

Thanks for all input guys, so they are same BTR/GKN and also on Cerbera, good,
but how long are they?

Just wondering if some kind soul may measure one?
Tied up at Malvern show with work for 4 days, then Debs moms funeral Monday, then work in Bournemouth Tuesday and Wednesday.

My 48cm measurement as previously posted was as accurate as I could get for the full length of the driveshaft (still have CVs on) so had to use a flat edge on either end of shaft. I don't suppose an extra mm or 2 would be critical for the length anyway (feel free to correct me...) Would be useful if somebody could double check - measure twice cut once... However I guess the key measurement you require is between the slots for the circlip?

If nobody gets back I will try and find time to bash the CVs off and measure up.

So....

Driveshaft lenght 477mm

First circlip outer groove is 5mm in from the end.

Circlip groove 2.25 mm (as accurate as I can get.

Second circlip outer groove is 36mm measured from end of shaft.

Distance inner edge of inner circip groove to inner edge inner circlip groove the other side 405mm.

Caviat. Measured by steel rule and circlip and circlip groove measured with calipers.

In a rush now - off to pub, but will double check all this tomorrow and might even do a drawing. Would be good if someone else could verify..

Cheers Matt, just the stuff.

Hi Mac,

Sorry, prob too late for you been a bit tied up everything I own being broken, but the Mrs went out on the piss and left be babysitting so had some quality time in the garage.

I also found my digital callipers so got some more accurate measurements and put them in a pretty picture.

So to put this thread to bed....

Watch him Matt....... He'll have you making him a set next........

Don't use diagram posted just yet, wait for confirmation it looks as if it may be wrong

What happened to the group buy idea???
Guess that was a good thing we missed it then.
What exactly is wrong with the diagram Mac?

Group buy seemed to fade out, so couldn't be arsed to wait.
The OE shafts fitted to my car [BTR diff'] are 22mm shorter. I've was led to believe they are all the same be it BTR/GKN/Griff'/Chimaera, but it may not be the case. Hoping someone may say, 'it's ok to fit as there is room' otherwise I have two unbreakable driveshafts for sale at knockdown price for cars with GKN diff'.

[macdeb]

Cheers Matt
I have taken the other side off and the lengths are identical each side. [BTR diff']

[macdeb]

Thanks Gary, it would be nice to have the definitive answer if indeed they don't fit so as to save any others having the same problem at least.

Anthony, with you but some parts suppliers seem unwilling to divulge details unless you are purchasing from them. That's business I suppose.

QBee said:

Mac, how long ago did you buy them, and was it by mail order? The distance selling regulations allow you time to reject the goods if they are incorrect I believe.

Hi anthony, appreciate the thought [crikey, people will be talking about us again for different reason ] But I ordered the length as indicated on a diagram provided by Matt who was trying to help in all sincerity and I'm not for one minute going to blame him. But, it appears he has GKN diff' and he measured the shafts from that so I supplied incorrect information to the manufacturer. What I was trying to avoid was having the car off the road whilst waiting for them to be made and delivered but I'm now faced with having it off the road for longer.
I'm going to try a 'dry build' with them tomorrow night and see if any clearance difficulties, if not I'll try them, but if there is I'll need to sell on [ideally to someone with a GKN diff' that's in the market for some unbreakable shafts at discount] before I can order some more as that would mean I would've spent £800 for them [£400 a pair] which is no good.

The solution is simple.
Modify all 4 wishbones by 22mm and flair the arches to accomodate the new wheel positions.

Get back on the lurve train bloke, cus' yer no use here

Quinny said:

I can't see why they can't be made shorter.... It's only machine time....

11 mm off each end, lengthen the splines and re machine the circlip grooves....just leave the old groove unused..

Edited by Quinny on Tuesday 22 July 14:32

What I thought [almost] though the start of the splines are the same from middle on both sets so the splines on the new are longer IYSWIM. So I thought machining off 11mm either end and putting a circlip groove in, job done but they're saying not possible. If they were too short I'd understand.
unless I have it wrong,
which is always possible,
I hate getting old.

i swapped a gkn for a btw diff. the old driveshafts fitted just fine

Edited by SteveSPG on Tuesday 22 July 16:57

neal told me this, but how come the differing shaft lengths Steve? Am I being paranoid?
