Thumbs up Tightened Steering Stem Bearings

My Wee sometimes didn't feel as secure as I thought it should on some fast runs, especially downhill. Tire pressure was right, and the forks are braced and lowered. There was no noticeable looseness in the steering stem when I jacked up the front and wiggled the forks or wheel, but I checked anyway.

I followed Black Lab's excellent instructions, and at step 13, to get more inside space, ovalled the wrench by squeezing it in a vise. Worked great.

The bearing lock nut was almost loose. With the front wheel off the floor and the handle bars & cables/hose off the steering, the front wheel flopped to one side or the other. I tightened the lower lock nut firmly hand tight,* the upper lock nut firmly wrench tight, and put everything back together.

My bike rides better. It is more stable at indicated 80 mph, and even feels better around town. Thanks, Black Lab. I have an All Balls roller bearing kit coming for the bike. (I know, the All Balls kit has Chinese bearings, but the good Japanese roller bearings of this size are adequate for rear wheel bearings for a Toyota Cressida, so the Chinese bearings should do fine in the lightly loaded steering stem. Plus, the All Balls 22-1003 kit includes seals.)

*I checked with a friend who is a great machinery mechanic, as well as with another friend who is an excellent all-makes motorcycle mechanic. Both agreed with me that firmly hand tight was good for bearings in this application. For a high speed application, like tapered roller bearings in a wheel hub, there needs to be end play (Timken says .001" to .007" axial clearance), but not in this type of a low rotation speed service.

"Older people who are reasonable, good-tempered, and gracious will bear aging well. Those who are mean-spirited and irritable will be unhappy at every period of their lives.

"Let each of use properly whatever strengths he has and strive to use them well. If he does this, he will never find himself lacking."

It is I that needs to thank you.

Possibly, you would pick up a stick, and along with me, continue beating the "dead horse" on this issue that I am passionate about?

Safe riding!
