Steering tapered bearings

[Incubus]

Tomorrow I take apart the triple tree because the steering on this old XS1100F is stiff. It could be the grease has just hardened up from 15 years of inactivity. It could be the bearings are toast. In order for me to know how careful I have to be, I need to know the price of carelessness before I start. Does anyone know a good source for these bearings? I'm looking for something reasonable, but at the same time of sufficient quality to last as long as the originals. A 27-year warranty would be very cool.

I would be very nice to find bearing part numbers that I could use to call the local bearing house, if needed. Does anybody know the generic number for these bearings?

Thanks

Patrick

Bearing supply place can cross them to what you need.....

XS11 upper steering head bearing part #HR32005XJ
25mm bore x 47 mm OD x 15mm ht

XS11 lower steering head bearing part #HR32006XJ
30mm bore x 55 mmOD x17mm ht
This is from a local bearing house in my town listing is for tapered roller bearing in metric sizes.
These are NOT Yamaha part numbers.
The #s on the actual bearings I took out are upper #32005JR
lower #32006JR
I'm just now working on adapting an R1 front end to my XS11E
it might work?
Cheers, 50gary

I got my bearings from Zanotti's (http://www.zanottimotor.com/) and if I remember correctly, upper and lower bearings were around 25 bucks apiece. If you do get them from here, they're not pre-greased, so you'll have to do that yourself.

After painstakingly tapping in the upper into the tube, I decided not to mess with the one on the triple tree stem. Totally worth the 10 bucks to have a shop use their hydraulic press.

+1 for the hydraulic press. I spent maybe an hour trying to get that one stupid bearing off before conceeding that it was pressed on... Do yourself a favor and have a shop press off the old one and press on the new one.

Also, make sure you have a drift pin or something that you can use to take out the bearing race from the frame side.

And of course, everyone's favorite trick for installing bearing races - put the new race in your freezer for a bit to shrink it

If for some reason you can't find the correct bearings in town (doubtful), you can get them from partsnmore.com - everybody's *favorite* Canadian store...a little sarcasm there by the way. The bearing set is actually timkin, so no worries...just don't buy the mirrors

Lacking a press, you can cut into the bearing with a dremel and use a chisel to snap it. Falls right off then!

That's the way I do 'em, Randy. (Cutting wheel in a die grinder)
Save the old races. Grind down the outer diameter on a grinding wheel(so they'll slid nicely in and out of the steering head) and use them to protect the new ones as you press(pound) them into place.
Same for old wheel bearings.

Just took apart the triple tree and found tapered roller bearings. Top was grease hardened and some rust, bottom was no grease but Okay. Cleaned both and found some brenelling(?) on upper but I think Okay What pre load do I put on the bearings when reinstalling? Using the notched nuts is there a way to use them to determine the proper torque, snug-up back off one notch etc?

Here's the thread you want to check out for the correct torque for the steering head bearing.

There - post number 2000 and I didn't even have to fluff my way in. All I had to do was post a link to something I already posted once!

While not the "official" procedure, I just tighten them up till there is no play or binding, kinda like a wheel bearing on a cage.

DOUBLE GURU... DOUBLE GURU!

snip) FWIW, my Yamaha shop manual says to install the bottom ring nut to 7.2 - 8.7 ft-lbs, and "do not over tighten it". A bit further on, they continue"When assembly is complete, check the steering stem by turning it from lock to lock. If there is any binding or looseness, readjust the steering stem tightness". (snip

I assume that bearings, nuts etc are greased up otherwise the torque will not be right I can use a 6" hook spanner and fish scale pulled to 15 Lbs should give me about 7.5 ft Lbs of torque, right!
