Rod change to gearbox interface

Postby DavidL » Fri Jun 29, 2012 8:33 pm

...for the want of a better title.

My gearchange was very loose and sloppy, but I've found out why, although I still need some info...

I found that
(a) the alloy cup which the gear lever's ball sits in (which is attached by rollpins to the main moving rod to the gearbox, and to a short tail going into the back of the alloy case) had become a loose fit on the long rod,
(b) the long (moving) rod had worn both itself and the bush it passes through at the front of the alloy case until there was about 2 to 3mm of slop, up, down, left, and right,
(c) the bolt which joins the forked end of the fixed rod to the gearbox is a very loose fit (in the tail of the gearbox). The bolt itself isn't worn enough to account for this.

(a) and (b) are problems I have managed to cure using new or newer parts, but (c) remains. I can't remember how this goes together - I presume there should be a rubber bush mounted in the gearbox hole which the bolt is a close fit in, but the last time I took one of these apart was about 20 years ago.

Can anyone remind me?

Sorry if this is in the wrong section, I suppose this section is meant more for answers than questions - please can someone move it if that's the case!

Update - it needs a bush, part number 13H7286, now on its way to me. I can foresee hours of fun removing the old one with the engine in situ...

Purely because I was digging through Photobucket for images for the forum, I came across this photo.

This is what I used to change the bush on the FD housing where the rod change yolk connects - bits of it were used to remove the old bush, other bits were used to draw the new one into position.

That's the old bush below the two long bolts, it was definitely overdue for replacement!

Sadly, I didn't qualify. I sometimes wish I'd followed a similar line to yours, but my "career" has been rather varied...
Children's portrait photographer, tractor driver/farm manager in Saudi Arabia, glider tug pilot, Class 1 HGV driver, computer programmer (that lasted much longer than all the others!), taxi driver, service driver for a BMW garage, computer programmer again, mobility scooter agent, is the story so far.

However, I'm thinking about quitting BMW if I can get my Class 1 (or LGV, I think they call it now) renewed, but I'm waiting for the weather to improve first!
