Wish me luck, I’m about to venture into new territiory and …
Change the bearings on my Coker…
never done anything quite so serious to one of my unis before, normally i wimp
out and ask the bike shop mechanic to do it for me.
So armed with " how to change your bearings" from the Unicycle sourse UK FAQ
I’ll head for the shed.
If you haven’t heard from me by sunday… send paul in to look for me.
bye sarah

I just did that last weekend, and they were very bad. I could barely rotate the
bearings with my hand. When you change them, make sure you put in bearings that
are sealed on both sides. The ones that were on mine were open on the one side
making it where lots of dirt and gunk could get in and destroy the bearing.

Well I’ve done it, not too hard a job, with as roger would say " the right
tools" I used a DM puller and it was quite easy to get the old ones off. They
were in dreadfull nick. One had shattered the outer ring, in the bearing
holder, its scored three groves into the holder. Fortunatly there was enough
left of the outer ring to get the puller around. The other one had a crumbling
shield so there were bits of the shield in with the ball bearings. My new
Bearings are sealed, hopefully they will last longer than the 100 miles I got
out of the last set.
I also put some 5 inch cranks on the wheel to try them out for size, even in
the short trip to work I could tell they were speedier. BUT the up hills were
harder and crosing a steep camber from the pavement caused problems when the
wheel got stuck
_______ HERE ______________ l___—
and I didn’t have the leverage to get it to roll out forwards. I suspect that I
will return to 6 inch cranks before too long, I’m not that good up hills.

The secret is having the correct tools… DM manufactures a special tool for
extraction of unicycle bearings. It is fantastic and enclosed the bearing
totally and pulls evenly. The other thing to use is a 3 leg bearing puller, but
the problem is getting one small enough for the 40mm bearings.

Hi Kevin.
An excellent bearing extractor from DM Engineering is now available from our
catalog, at: http://www.unicyclesource.com/DM_Engineering61634.html
Makes easy work of bearing removal.
