87 WR430 disc brake conversion

I ended up using a COM10T bearing; had to grind 0.006" off to make it work.

Swinger is sorted. Now to lace up the rim and figure out the master cylinder placement.

why did you change that it looks like an 87 swingarm
are the oem not available?

It is indeed an '87. The replacement bearings that I was able to find were $95 or so. The COM10T is apparently still in common production; $20. The specs work out and taking 0.006" off is no big deal. Perhaps a poor choice on my end but I'm giving it a go.

I had no idea the bearings were that much
thats 95x all the bearings? there are a few bearings involved
my dealer still has NOS and he gives me a decent price on these type things

I am interested in how you mount your brake reservoir
i measured the swingarm and concluded the 92 wheel fits, but i am milling my swingarm for the 92 axle
the caliper mount seemed like the only real problem as it needed a little taken off the back to allow the wheel to align the sprocket
what did you do with the caliper mount

I was able to source most of the required parts from Halls. That one bearing was quoted at $95 (not from Halls as it is not available from them). The good news is the bearing is still available; just more expensive than I wanted. I did not like the price on the swinger bearing parts either so decided to make them from drill rod (silver steel for those across the pond). Since I've the capabilities to do this class of work it just seemed to make sense to make them. I'm thankful they are still available as most folks will need simply to purchase them.

Who's your local dealer? I thought only Halls was the only dealer who stocked vintage parts.

very small dealer, sold these when they were new

I machined the bushing to accept the 15mm axle. Made it ~ 0.30" thinner on the face and also took off ~ 0.050" from the caliper at the anchor location to allow as much room as possible for the anchor weldment and to allow the caliper mount full front to back travel. It's a tight fit but seems workable.

Nice work. I always thought about doing that to my bike but I don't out ride the brakes anymore. (I got old)

85-88 swingarm bearings are hk2216-2brs
available anywhere, they are not husky specific. just like the wheel bearings, pick a good brand and just order 6302-2rs..
if you buy them packaged as "husqvarna bearings" they are triple price..

both of these are still "common production"

This how I mounted mine on my bike. Seems to work well and is out of the way.

where did you put the reservoir ??

That 1 has a built in reservoir

Like 86 400 XC said that one is built in. It's off a 2010 250 TC

that solves a big question for me
as the air box was in the way with my 93 master reservoir

is there a window for level checking?

Yes it's on the back. You can see the outline of if you look closely

They should tell people these things...
