Been obsolete for at least 5 years... Only choices are second hand or refurbished with poly...  ;)

Are there any about or is it a diy poly job?
Possibly some from Poland, but easy enough to diy :y

I can't remember the name of the Polish company but when I inquired a ways back they had problems. Do you know if they are all sorted now for the Omega polys?

This is when they discover that your diff mounts are knackered....

Nick, Can the diff rubber mounts still be bought and do you know the part number?


They've been NLA for ages. Repairing existing ones is the only option.


Like this, stripped and clamped in a jig:





and with the polyurethane cured:

Can you provide the measurements of the jig and where did you get the correct polyurethane mix from?

Thanks

Andy, that jig is way over the top for one offs. It's intended to be reusable, which is why it's cobbled together out of ScrapbiniumTM
If your mounts are still more or less attached, you could make a jig from thin board, glue, nails and some aluminium foil in about 5 minutes. Once you've made the jig, cut as much of the rubber out with a hacksaw, then finish the rest with a wire-brush in an angle grinder.


Correct polyurethane? Who knows? It's just the stiffest that was readily available. You need about 300g to do both mounts. Get some black pigment; it just looks better:

So the foil is to go in between the board and the poly.  :y

If they say the bushes are knackered I'll have ago.  :y

As for the black pigment. Would some old ink cartridges do for that?

Fixed properly ;)


The pigment is a couple of quid when you order the polyurethane so it isn't worth trying something else. And it only needs a couple of grams for the small mix we need.
