Pin out! No swearing!

Some small dumbbell weights provided the perfect base with a hole to drive it out

Excellent hopefully the postman doesn’t delay, although you are on the other side of the world.

I’m sure postie will make it to this faraway land tomorrow tomorrow.

All the bits of the coupler cleaned up, pin de-burred and ready for the bushes

Silly question (well, hopefully not..) you didn’t remove the longitudinal staking in the pin did you? Reason for asking is that it looks like you have sanded it flatish. That’s the bit that holds the pin in the housing

So….

Refitted based on my indexing when removing

Image

Which was a bit vague to say the least! Reverse seemed to be where 4th should be

So using a guide online I adjusted it from scratch and then played around for a bit before….

Taking it up the road and it all felt good - much better than before I had the issue

So now to torque everything up and then go for a really good run to be sure

Thanks for the input and advice and to Jon for the bushes

Hopefully job done and it can come to the big event again

Nice ! I have always installed the bushing without removing the pin.....Never knew it was possible. Removing makes much more sense than leaving parts in the freezer and boiling jugs of water :shock:

Might also be worth putting some safety wire around the small set screw that connects to the gearbox shaft, so that it can't work free (the set screw can't be overtightened !).

Worth checking the shifter end also, there's another set screw that holds everything onto the shifter rod.....Mine worked loose and I ended up with only 4th gear.

Cheers Chris

Pleased to say just took it for a spirited run to petrol up and all good, more precise than I remember it before the issue so good news all round

How the hell did you manage to do that! No wonder you swore a lot

Indeed. I presume he pushed the flange through from the outside

It's always trouble when you start pushing the flange
