The JCP site is a law unto itself, the gearbox mounting is under the engine section!. I live in hope that they will discover hyperlinks between sections 'ere long. This is the link:

Thankyou very much that's brilliant

 

I just took mine out.

Guess I'll have to clean it up a bit...

it looks in the diagram that there is just one rubber/ spring seat on each spring?mine had 2 on each spring? has a previous owner cocked up do you think? thanks

 

Long story short: one for each spring.



There are two springs, an inner (#13) and an outer (#4).

The outer spring is assembled inside the unit that is contained by the buffer ring (#8) and the spring cup (#2). Place one rubber spring seat (#3) under the spring, the place the spring cradle (#5) on top of the spring (it is attached to the locating weight #6).

And here's where mine was mis-assembled: place the foam buffer (#7) on top of the spring cradle (#5). Mine had been assembled with another rubber spring seat (#3) instead of the foam buffer (#7). #3 and #7 are not the same part (and #7 costs a lot more). I was lucky that the replacement kit I bought had the correct foam buffer. (If you watch the Wheeler Dealer episode, you'll notice he assembles it with two #3's, and no #7 which is incorrect.)

In this pic, note that I had an extra #3 on top of the outer spring - not needed, so I removed it. Also note that the foam buffer #7 fits perfectly into buffer ring #8:


Once that is assembled (you have to compress the outer spring inside the unit and bolt it down, not easy), the inner spring is placed on top of all that and is compressed against spring seat that is attached to the tranny.

Here's how it looked ready to go in:



Interestingly, the diagram only show one rubber spring seat #11 on the top of the inner spring. I used one on the bottom as well, but you should be OK with only the one on top.

This pic show me lining it up, before it is bolted down:


Installed it all, and now the tranny hardly moves.
