Hi,

I've recently rebuilt my engine for the first time following sticky's book, etc. It's gone pretty well but I've been suffering jumping out of gear in mostly second but occassionally thrid gear. It's not every time and seems that after it's jumped around a bit it eventually goes in and stays in until I change gear again. I didn't replace the sliding dog when I rebuilt it so does this sound like the problem? I've tried adjusting the cables but it doesnt feel like it's the cables causing it, though I could be wrong. My next idea was to open up the casing, check the endplate and after that replace the sliding dog.

My main question really though is can I replace the sliding dog with the engine in place and back wheel on? After spending ages messing about I just want it sorted, so if anyone can give any tips on the easiest, quickest, least disruptive way to get in there and get it sorted it'd be really appreciated.

Cheers.

Check your cabling first.....

I've tried that - tightening them, loosening them, to be honest I'm not sure how tight they should be but niether seems to make much difference. I can sort of feel it falling out of gear and then back in again without putting any pressure on the lever. I'll try readjusting again to be on the safe side anyway before I get my hands dirty.

It could be sliding dogs and/or gearbox shimming. If you buy the sliding dogs with a modification with 2 of the arms cut at 45 deg you can change it in place.
My thoughts are that if you are that far into the gearbox its not much more to take the hub off anyway, making the dogs easier to fit and check things over.

Check that you have fit the gear swivel baseplate the right way around. Also if you have rubber gators on the gear cables they can compress and force the gear swivel to move and drop into a neutral in between the gears.
