Yeah it is, basically what’s the best way to get paint out the thread?

Underdog1:
Well.. I ended up getting the grease nipple threaded in, huzzah! Can get the rear end all bolted up...
Maybe not. After I installed the swingarm I was moving the swingarm down to get the shocks bolted up and I managed to snap the grease nipple off against the engine casing somehow..






Really annoying. Might be because i had the grease nipple pointing forward towards he front of the bike, must be a really tight clearance thought.

On another not in having an issue getting my front wheel bearing retainer in, it’s a pattern part and it seems the threads are ‘tighter’ than the oem one I’ve got (which is mangled) a anyone else noticed this?

Underdog1:
Rear wheel laced up


And this is as far as I can get the front bearing retainer in, even tried hitting it with the impact driver  ::)

MCTID:
Mine was just the same......it was an absolute pig to get it out.....you should have seen the 'Heath Robinson' affair I rigged up on my Workmate to remove the rear Bearing Retainer (I'd stripped the rim off it - so it was just the hub).

I bought new Bearing Retainers but they also proved tight to insert so I asked my local Machine Shop to 'ease' out the threads in the Hubs......which worked a treat......well worth £20 for both Hubs.

The way I looked at it was that I wouldn't like the next person who stripped a Bearing out to go through what I had to.

Might go down this route, was it the hub the machines the threads in or the bearing retainer? Might hold tight on lacing the front wheel up. Seems a bit of a joke to have these things staked in, on what planet are these things backing out?

Once all the bearing retainers are in I was thinking of putting a glob of locktite down each stake hole rather than restaking - any issues with this?


On a more positive note I got the snapped grease nipple out the swingarm



The first time in history an easyout has worked
