how do you change the UJ's on a front prop

(1/3) > >>

nickW:
ive never changed UJ's before so does anyone have any tips

its a disco 1 front prop

denviks:
you will definatly need a vice  :wink:  once you have removed the prop take out the 4 circlips.  now mark the position of the uj to the prop so that it all goes back together the same way. ( balance ). now you can use a dreft to tap out the shells on the ends of the uj. push it through one way and remove that side and then push it the other way to remove the other shell. you can use 2 sockets in a vice for this. one bigger one that the shell goes in to and one smaller one to push the shell though.

before fitting the new uj make sure everything is nice and clean. half fill the new cap shells with grease making sure roller bearings are in the correct place. now reasemble...

easy huh...... :wink:

Strange that  :shock: guess what I've been changing this morning  :wink:

Hardest part is getting the circlips out as they're either stuck in the groove or just want to keep jumping back into place  :evil: New UJ was only £4.90 inc from our mate John Craddock  8)

Didn't sound like a UJ gone though, sounded more like something vibrating in the n/s/f wing. The air cleaner housing was rubbing the turret, but I packed that, even took the air intake off from in the inner wing, but the noise persisted (albeit intermitent)

The holes in circlips are tapered, so depending which way they are put in, the circlip pliers will either work a treat removing them or be a pain in the ***.


Or to put it another way, make sure you put the circlips back on with the smaller hole facing out.
