restoring a Up-Tite 87 250 XC...

[wrx]

just replace that roller with an aftermarket MSR chain roller. that 30 yr old one was gonna fail on you anyway.

I MADE MINE CHECK WITH PHIL OR ANDY BET THEY HAVE BOXES FULL

I messed up...
...was working on getting new parts back on the polished swing arm. Pressing new bearings into a thirty-year-old NOS chain roller cracked the roller. I should have warmed up the roller first, maybe that would have prevented this:

These original rollers are hard to find. Argh! At least I didn't crack the bottom one. XC bikes have 2 rollers. WR bikes have 1 lower.
The needle bearings are easy to source and halls will have your washers. Take a look at my disc brake conversion for part numbers. I used a different bearing for the large one.
Next, considering whether to clean up this linkage knuckle. Originally they used a fiber washer, now wasted, as an outer spacer... I think. Don't think new fiber washers are available.
Bearings look good, was thinking of just cleaning and greasing it up good. I can get some of the bearings - but not all.
Anyone have any ideas on how to service this?

Halls has your washers and the needle bearings are easy to source.

Thanks, Darrel.
I'll give Halls a call.

 

[Darrel78]

Thanks, Darrel.
I'll give Halls a call.

Let me know if you need me to size up one of the COM10T spherical bearings for you. The Husky bearing that I found available was über expensive.

COM10T, is that the bearing at the top and bottom of shock? 15 11 332-01. I have a NOS pair of those.
Hall's has responded with the linkage parts they have. I'll get those parts. But still will be missing some bearings.
I'll let you know what I don't have.
Thanks.

It's the big bearing in the lower link. 15 11 256-01

I see. There are 2 bearings there. I don't have any of those.

I was told by a knowledgable source that one of the linkage bearings is not made or available any more by Husky or anyone else. I don't remember which one.
Do you know anything about this?

I talked to Hall's today, they are sending what they have... I don't know exactly what I will receive, since their part #'s are not Husky part #'s. (maybe Cagiva part no.?)

all you need is a hunk of 954 bearing bronze and a lathe theres an aussie on here that made it work if push comes to shove i might be the first yank

I just refurbished my 87 when I changed the brake over to disc and ran into the same issue. Part numbers are changed but Halls had the bearings for the shock and all the associated seals. The ends of the spherical bearings are not available from Halls nor are the spacers the needle bearings ride on. Several of the vintage parts suppliers can get these parts so they are available just pricey. As I've a lathe I made the parts I needed that were not readily available. I've a COM10T bearing heading my way. I'll size it to fit and send it to you for evaluation if you like. Seems two are required; only one of mine needed replaced.

We'll get you to the other side of this rebuild easy!

oh hi Darrel u get your project yet?

Darrel, that's cool. Thanks.
My needle bearing spacer is OK but it is worn. I'll just reuse it and keep it greased.
Yep, two COM10T bearing types. One for the vertical link the other for the wishbone end.
I'll inspect all the bearings and see how they look.

You should post a pic of the 87 430 w/ rear disc brake. It would be nice to see it. A friend of mine just did his 87 430 WR with a KTM disc brake. My 430 Auto could definitely use one.

oh hi Darrel u get your project yet?

No, not yet. Another couple of weeks yet. On another note, I had brother pick up a Buell M2 for me. ( I hear he still has room on his trailer)!

Here we go. I made a bracket that bolts on to carry the master cylinder. Used a WXE wheel.

how did you fit the wheel i have an interference of about .050

 

[Darrel78]

Mine seemed to fit ok. Search up "disc conversion" for my article. I think I gave all the dimensions there.

Getting the wheels ready. Had to grind the rear spokes to remove them. Sending front and rear spoke / nipples samples to Buchanan to make SS spokes up.
Here's the rear brake drum before Evapo-rust.



After Evapo-rust-- nice.
