How Do You Adjust the Steering Stem Bearing?

DUH....
But, the setting is a torque value on the stem bearing adjust nut... which is impossible to torque because you have to turn it with a hook-end spanner that could not be connected to a torque wrench.
Anyway, I had my front wheel up and mine was set too tight because it had a sort of "detent" feel as I turned it, and it had definite drag to it. Felt much better after I loosened it a bit. The place I left it is nice and free but I don't feel any front to rear wobble in the fork with my hands pulling at the bottom.
I assume there is a better way to set it than just tightening until the play in the fork is gone?

Thinking the detent feel is when the ball bearings roll past dents in the race.
For consideration:
Z1E's tapered bearing
Good Luck!

Yea the detent is normal, first pothole the front wheel hits by 100 miles the races get a slight dent, and the dent gets a little bigger every pothole for the rest of eternity, so after 100,000 of them you'll definately have that nice detent in the straight ahead position.
Hmmm... I never thought of that. I guess that explains it.:laugh:

TA x L
= TW
L + A
L = Effective length of the wrench as described below.
Dial Wrenches = The measured distance from the center of the square drive to the center ring or notch on the handle.
Micrometer Wrenches = The measured length from the center of the square drive to the center of the handle, with the wrench set at the desired torque reading
A = The measured length from the center of the adapter drive to the center of the wrench square drive.
TA = (Desired Torque) The torque value designated for the fastener with or without an adapter.
TW = (New Setting) The torque setting on the wrench allowing for the added length of the adapter. This reading will be lower than the desired torque.
In my case, using the 7†spanner/adapter, and desiring 260 inch pounds of torque on the steering stem bolt, the formula looks like this:
260 x 8.17
= 140.0
8.17 + 7
So, I set my torque wrench at 140 inch pounds to apply 260 inch pounds of torque on the steering stem nut. Your numbers will be different depending on the length of your wrench and adapter and the amount of torque you desire.

I like the home made tool idea..... I make lots of useful tools (especially for my gunsmithing), most are made from either popsicle sticks or coat hanger wire...:laugh:
BTW: the manual spec on mine says 20 - 24 ft-lbs of torque on the stem bearing nut which seemed kind of high to me....
