J15/Riot driveshafts

Hi
How did you folks calculate the amount of driveshaft that needs taking out, trial fit and guestimate or just measuring and calculating ?

Thanks

I cut the originals in half then offered them up, marked the amount that needed to be removed, cut that out, tack welded them back together and then sent them off to a specialist machining company to use as patterns for a new set.

I didn't want welded and sleeved drive shafts so I paid out for a new set guaranteed up to 300bhp, plenty obviously.

Yep - exactly what i did - without the welding! Cardboard sleeve and gaffer tape.

Push in to full depth and then pull out to having the outer edge of the tripod flush with the end of the cup, then work out half of the difference so that the tripod end up in the middle! Simples!

You only end up removing about 25-30mm, and in most cases they are the same left and right.

A couple of builders have had them friction welded.

I had mine made by the guy in Chesterfield that JP recommends.

Really nice job and perfect fit.

Similar but different, had mine friction welded by CPS Drivelink.

I used XR2 driveshafts - fit straight in.

Paul AS - 7/1/13 at 06:49 PM

How come I didn't know it was that simple? Jeremy??

nickm - 7/1/13 at 08:13 PM

Thanks Fellas
Might try theXRr2 route first as its the easiest and might be cheaper by the time i have paid for the welding but i believe they are rare.
Dont expect a video of a J15 anytime soon though as i cant even post stills on here.

Thanks

Well that's a very interesting twist......

Tell us more....what model xr2?, do the xr2i ones fit...do you have actual lengths...was it the cvh engined xr2s?

Apologies, but this is exciting news :-)

Hi
I had heard that before from Riot builders but they are very very rare if you find some after youve ordered yours give me the details !!!

I have a pair of XR2 driveshafts left over from my first engine install that may be up for grabs if anyone wants them? Open to offers...

Here's a photo of them installed in my Mojo with a 1.25 Zetec SE.

Im suprised it hasnt been mentioned before, it is well known on riot/mojo build threads.
But anyway, MK2 XR2 (cvh engined ones) fit straight in. You need to find a specific CV joint for the OS inner though, i cant remember which it is, but I will do some digging.

monkeyarms - 8/1/13 at 08:36 AM

From, and thanks to http://www.r1ot.com/nov06.htm

Finally I have got the drive shaft issue figured out. If have MkII Ford Fiesta XR2 drive shafts and you need new CV joints, on the outer joints ie wheel side standard XR2 CV joints are fine. On the inner side you will need to note that there are two kinds of CV joints available. This one is used on cars from 1986 onwards and where the boot fits it will foul the block This CV joint was used on pre 1986 cars and has a longer body which will also allow a greater "plunge" to take up any slack and give a greater range of movement its AMK number is TDL3602 and it's only suitable for use with XR2 drive shafts. The drive shafts for the smaller engine cars have a smaller diameter on the splines and will require different CV joints (obviously).

Ed why didnt you use the XR2 shafts when you swapped to the 1.7 engine?

Madinventions - 8/1/13 at 01:21 PM

The XR2 O/S driveshaft is a single piece and didn't clear the exhaust when I upgraded to the 1.7 Puma engine (I used the stock Ford catalytic converter). I now have the Puma type driveshaft which is split into 2 parts with a central bearing support.

Puma type:

XR2 type:

If I had used a better manifold with the cat in the silencer, I would've kept the XR2 driveshafts but it was cheaper to chop up some Puma dirveshafts rather than buy a new cat...

Hi Madinventions
I have sent u a u2u

Found this thread that may be relevant:

http://www.locostbuilders.co.uk/viewthread.php?tid=173483

Relates to cars with uneven drive shaft lengths.

nickm - 10/1/13 at 08:34 PM

Hi
Did speak to Jeremy and he reckoned torquesteer wouldnt be an issue with my car, the support bearing is put onthe other d/shafts to try to eliminate that.
Im hoping for 145=150hp dont know about higher outputs. I drove a puma 1700 for 3 years a cracking little car and pulled like a train when the vvt kicked in would this affect those with vvt ?.

Nick M

theprisioner - 10/1/13 at 09:06 PM

My view is it should only affect those with dissimlar driveshafts lengths ie those without the central bearing.

monkeyarms - 11/1/13 at 10:28 AM

I think people are over thinking this issue of unequal drive shafts. Im sure both styles will be fine.

A Mojo with a 1.8 zetec on throttle bodies has unequal shafts with no issues it seems.

From and with thanks to http://www.mymojo.co.uk/



Just pick a method that suits your build and enjoy

Jenko - 11/1/13 at 02:09 PM

Agree....plus these are not the wheels doing the steering, so can't imagin this being an issue.

nickm - 19/1/13 at 08:02 PM

Hi Ed
Are you out there i have sent you a u2u with a few measurements

Thanks

Nick M

Madinventions - 20/1/13 at 12:01 AM

Hi Nick,

Sorry - fell off the radar there a bit! I've found the OS driveshaft but so far have not been able to locate the shorter one. Situtation hasn't been helped by being too damed cold to be in the garage much, but I will don my best wooly hat tomorrow and venture out there to have another good look for it. As soon as I've located both I'll check those measurements for you.

Apologies for the delay.
Ed.

Bit slow on take up with this thread! It is my car pictured a few posts up... good to see people are still finding the website a useful resource!

Unequal length shafts are indeed only an issue on FWD, never noticed any problems on mine. Will shortly be back on the road with 2.0 zetec & iB5 gearbox out of a Ka so will have to see how the XR2 shafts hold up!

BTW, the Mojo was originally designed around CVH engine / gearbox / driveshafts / uprights of a Mk2 XR2 which is why these are a straight fit. I just chose to go to a zetec instead. As Mr Ford seems to like a lot of carry over standards, the Mk2 shafts fit into much more modern iB5 gearboxes, the splines, seals etc all just work.

Another bit of info - the XR2 shafts are different (chunkier) than lesser Mk2 Fiesta versions. They had to cope with 96bhp after all...
