I need to replace the bushing in a two-circlip sleeve gear. Anyone have a trick for getting the circlips out?
 
As per Mick Hemmings Video on Gearbox rebuilding:
Use a small ball end Dremel tip diamond grinding burr between the groove of the circlip. Work the burr down till it gets to the bottom of the groove in one location so as to create a divot. Move the circlip end over the new divot you created and use a pick or small watchmakers flat screwdriver to pry it out.
Try using a small watchmaker screwdriver first to see if you can pry it out, if at all possible, then if that fails go to the more drastic measure of removing the circlip with the burr trick.
Cheers,
Tom
 
Greg,
I would use the longer bushings as these have a better friction value when pressed into the sleeve gear. that is why the circlips were introduced because the shorter bushes had a tendency to walk. Mrk 3 type:
Yes, it's a MKIII, with 2 circlips. Pretty sure they always had the longer bushings and there is no room to "walk".

It looks like someone tried to ream them - the marks and the sloppiness are not wear.
 
Those sleeve gear bushes don't receive much splashed lubricant in service, tucked away as they are, so best keep an eye on them!
Don't run the bike in neutral for long periods of time like waiting for a long train. The main-shaft is the only thing revolving with the clutch pack in neutral and the layshaft and it gear sets is not spinning which would be feeding oil up to that sleeve gear from the bottom of the gearbox. I agree. The sleeve gear bushes and the first gear layshaft bush always seem to take the beatings. Keep an eye on the triplex chain or belt drive tension as too tight puts a lot of pressure on those sleeve bushes. Nuff said.

The trains here in the UK, and even on the continent, are nothing like as long as you have in Canada, as the distances here are so much smaller, plus there's less abundance of natural resources, but that's a really good point CNN.

Made several very small screwdrivers out of small screwdrivers - no help. So, I used the burr method - was easy to do and they came out just fine. I used a pointed metal burr, not a ball-end and not diamond.

Real shocker - when the first circlip flew across the shop, I saw it land :)

working in a small cardboard box( around your hands /item) may help with flying components. We’ll leave cats to work entirely in a box☺️…..
