Please can someone confirm "up to 2A638133" means up to 2002? Why would Paddock's Bailey-Morris prop only suit TD5s up to 2002? I wonder why they don't stock HD props for Pumas?

Okay - enough to think about for a while and loads of good info. Thanks again Gents (and Gentesses) Bow down Tell someone you love them today because life is short.

I brought my props direct from Bailey Morris. Very nice people.

A mate of mine had a vibration on his Tdci, he fitted new prop, but this did not help, so altered the fazing of the uj's and that sorted his issues, he did this with advice from Gwyn Lewis.

Thanks for the info Andy - on your and other people's advice, I will be contacting Gwyn Lewis to see if he can help.
Embarassed er... what's "fazing the ujs"? Tell someone you love them today because life is short.

Phasing the UJs refers to the alignment of the UJs on either end of the prop in relation to one another.

Basically, a UJ is not a constant velocity joint and induces variations in the rotational frequency (manifested as vibrations) when operated at an angle. To combat this the UJs are aligned so as to off-set this as much as possible.

For the rear prop (which has equal and opposite operating angles at each end) this means the UJs should be in phase - and the variations cancel each other out. The yokes should line up. On the front prop the operating angles are not equal (as the diff nose points up slightly) so the correct angle is slightly off being lined up. 30 degrees rings a bell but don't quote me on it. This doesn't completely cancel out the vibration but it does as best as is possible. This is part of the reason Land Rover went to a double-cardan front prop on posher vehicles - as it removes this driveline vibration source.

At any rate the propshaft should have alignment marks on the tube section either side of the sliding joint to allow the correct reassembly if it is split for servicing.

Thanks guys Bow down

That would explain why the vibration improved when I refitted the handbrake drum...
Are there 4 possible phase positions or just 2? Otherwise I'll look tomorrow Thumbs Up

There are as many as there are splines on the shaft!

It shows this chassis number on microcat too. must be the last Td5 number.

the prop is splined so you can adjust the phase by rotating it a spline at a time.

are those angles correct on a puma with the the difference in gbox angle mounting compared to a td5?

if you are just trying to see if the rear prop is at fault have you tried removing it and driving without it for a bit? i am guessing you may of as you mention vibration reduced when you refitted the handbrake drum. Cheers

Unfortunately, Gwyn Lewis can't do rear props for a 110 Puma Sad

Oh well - plenty of other ideas now - determined to get it balanced and checked in-phase Thumbs Up

There are businesses who specialize in drive shafts and every part that comes with it. I just finished a project with one and IIRC they had spicer quite high up their quality list. Scaling the real deal.

Actually, I must say that Gwyn is an incredibly friendly and helpful guy - I've learned a lot in a very short time, also a bit about how the Puma propshaft was developed by GKN at the start. He was involved. Apparently some testers even refused to drive the test vehicles until vibration problems were fixed Shocked

He also confirmed that the Puma setup is "not exactly optimal" which is why GKN had significant problems at first. Apparently the stock propshaft is already semi-wide angle to cope with the standard geometry and lifting a Puma more-or-less demands a DC.

As Gwyn seems to be planning on buying a Puma, I hope it will result in even better modified Puma parts Wink Tell someone you love them today because life is short.
