First off I need to apologize for some miss-imformation that I put out here.

I recieved the Timken bearings #W205pp the other day. Today I got the bearing puller/installer tool and pulled the first bearing. I compared the stock 9276 bearing to the new timken and found the timken bearing is wider then the stock HD bearing. Inner and outer diameters are the same.

Well I went back to my sources and the one website claiming that the bearing they carried was a replacement for the stock HD bearing is wrong. So I went to Timkens website and found product information on the w205pp bearing. Its still a single row bearing but its the same width as a double row bearing. It has extra space for prepacked lubricant

You can see the difference in the picture with the bearings side by side. The second picture is the spacer that goes between the bearings in your wheel to keep pressure and depth on the inner part of the race that spins the bearings. The scratch line on the right side of the spacer is the amount Im going cut off.

If my measurements are correct, after re-installing this with the new wider bearings the depth should be correct and no additional outer wheel spacers are needed.

This is trial and error for me. Im looking for a possible solution to this problem with the failing bearing for the front

Gotta hijack your thread for a minute. Every time I see a picture of your trike all I can think is WOW! That RoadGlide nose on a trike is OUTSTANDING, and I love the color scheme. You've got one good looking scoot!

Hijack over.

 

Thank you for compliment

How many miles do the old bearing have on them? Did they have rough spots. Keep us updated.

 

I had between 15k-20k miles on these bearings. What I found after removing the left bearing and pulling on the inner race there was a small amount of play. I would hear a howling when I would make either a sweeping right turn or if I powered through the right turn.

I am getting the inner spacer cut tomorrow and hopefully the indy shop will call and tell me the narrower spacers are in from Drag Specialties.

 

New bearing are installed in the wheel. Had the inner wheel spacer milled down 3/16" Both new wider bearings protrude about 1/32" out of the bearing cup on each side of the wheel. I got the spacers that go between the forks and the wheel from Drag Specialties today. I thought I had my measurements correct but ended up milling one spacer to narrow. Now waiting on another spacer to arrive to mill to the correct width.

 

I have attached a few pictures of my wheel with the new wider Timken bearing. The bearings are just about flush with the rotors on both sides. What I had to do, was to have the inner sleeve milled down to be slightly shorter.

I have 3 seperate inner sleeves #41900-08 each one was stock for comparison. All 3 were slightly different in length brand new. Also in the front wheel is a bearing spacer that is on the left side. This spacer is #43903-08 in my parts book. This spacer is only on the left side of your front wheel and has to stay in the wheel.

To keep the bearings spaced evenly and keep them as flush as possible to the out part of the wheel, the inner sleeve #41900-08 has to be cut down so you have about 3/16" of the sleeve sticks out past the inner spacer #43903-08 on the left side of the wheel.

After installing the new bearings I have been working on sizing the outer wheel spacers that go between the forks and wheel. So far I have one done and will have the second one milled down a little more tomorrow to finish.

Thanks much for the info.

 

Just a fyi, the DK bearing which are the bearings HD is using #9276 is made in India.

I think and this is just my opinion, any narrow single row bearing manufactured with the limited amount of grease that they all come with due to the space of the bearing assembly, will have to be checked after 10k miles because of the number of failures in this mileage range. This might ensure you wont have a bearing failure past 10k miles
