I have a type 9 gearbox from a Sierra P100 deisel pick up which came with my kit. Now the chap i bought it from said that the gearbox has been checked and it's all ok. From what i remember from my last gearbox this one has a very thin link where the gearstick sits. The saddle (or what ever it's called) in the gearbox looks very worn to me and i'm sure std type 9 box's have thicker saddles. It also just looks wrong to me.

I have a friend who uses a gearbox chap for his A series mini gearbox's and he has quoted just under £30 to fit a new saddle thing.

Question is, is it worn, is it easy to replace and are they cheap new?

Here is a pic of what i mean:

Dead easy to replace...

Use a bit of wood through the top hole to tap off the aluminium cover from the back hole (oooer!)

Put the gearstick back on & put it into 1st. Take the gearstick back off again.

If you look down the hole you should now see the roll-pin that holds the little cranked bit onto the selector shaft. Tap this out and the crank should come off through the back hole with a bit of tugging.

Go to a scrapyard and do the same to an old type-9 box with a decent crank.

As the Haynes manuals say "assembly is the reverse of the disassembly" - just push on the new crank and tap the roll-pin back in.

£30 Pounds is a bit cheeky - it's a 10-minute job if you have the replacement to hand.

I don't know if you're aware of this, but the P100 gearbox uses totally different ratios for 1st, 2nd and 3rd from that of a standard Sierra, (remember, it is designed to lug around heavy loads) so you may not find it suitable to use for your application!!

Last Indy had a Transit gearbox which i believe had similar ratios and i loved 2nd gear!!!! It really flew in 2nd and 3rd so i'm happy to keep it.

Mine looked quite worn too when I took it off so I just made a little nylon bush to take up the slack then put it back together again and it's been fine since with no slackness.
