Universal joint in propshaft - can I disassemble/reassemble?

[charlie_pank]

I have a 2 piece propshaft and I want to get the rear section replaced with a TRT. I know Bailey Morris will do this for me, but I was wondering, if I get them to send me a TRT of the right length, attached to half a UJ, is splitting the old UJ and then linking up the new one something I can do myself, or best left to the experts?

For something spinning at high speed right next to your body I would always leave it to the experts !

If you have the following items it is pretty straightforward;

 

1. Circlip pliers

2. A vice

3. Socket with inside larger than bearing cups

4. Socket with outside smaller than bearing cups

(You will be using these as a spacer to press out the bearing)

 

General idea is to remove circlips, put large socket on one side and small socket on the other and press the cups out into the large socket IYSWIM.

That's it? great, I can do that!

Many moons ago I decided I was fed up with getting ripped off by garages in SE London, so I began working on my car myself. The future Mrs Pank expressed some concern that I was changing the brake pads, and 'what if I got it wrong?' etc... My response was this: 'I'm following the instructions clearly laid out in the Haynes manual. It's either me doing it or some teenager down at Kwik-fit. Who do you think is going to have a greater vested interest in getting it right?'

Edited to add: Much easier if you don't push the cups through to the middle of the yoke.

You will need to get the assembly balanced.

Beat me o it mic!

Beat me o it mic!

 

By about 14 hours

 

Maybe ask the supplier if they balance each section individually or the whole assembly?

Fairly common job on Land Rovers. Never needed to balance a rebuilt u/j, a long as the new one's orientated the same way as the old one in terms of the location of the grease nipple. I just mark the shaft with a paint pen, and have never had any snags.

Another thing that i always do is fill the new u/j cups with grease as it seems to keep needle rollers against the sides of the cup when refitting u/j.

You need to balance it as one part is being replaced, not just the u/j!

We just sent BM the two piece propshaft, and they converted to TRT and balanced it all. Wasn't hugely expensive and I think most people would recommend this route for the balancing.

 

The Caterham tunnel is a bit narrow, so make sure they know this and fit a narrower tube.

 

[charlie_pank]

Thanks VE, that's my plan. There seems to be plenty of room inside the tunnel at the moment. I can't imagine they would make it thick enough to be a problem!

Sorry, misread the original post.

Forgive my ignorance - converted to a what?

[Myles]

Although amusingly, I find that my Westie was built with one (once the reverse box was removed): 😬 😳

Torque Resilient Tube?

 

I think these shafts are made from 2 tubes, one inside the other & bonded together with a rubber

[charlie_pank]

Yep - reduces the drivetrain shunt from the bike-box

And now I've read a little around it, I'm glad that I've never dared do anything other than a granny-start in this car!

 

Admittedly more out of sympathy for the poor ickle clutch rather than the gearbox and/or prop, but still...

So you have the legend that is DH2's old car ? That was a work of love, followed his progress and he helped out on the Craig's Phoenix GSXR1000 build (an ex Caterham 21 owner) from which I got a lot of help.
