Hi all,
Is there a recommended torque setting for tightening down the nut
on a front spindle to hold the disk brake rotor on? I have the old
Brit Leyland ring-bound Spridget shop manual (circa 1970) and there's
no torque spec in there. How tight is adequate, and how tight is
too tight, i.e. shortening bearing life(?) or some other problem(?)
Some background info for anyone patient enough to read -
I've got the Frontline larger disc brakes installed, with all new
wheel bearings, and yes, the bearing thrust orientations are
correct. But seems like over the past year, my right side rotor has
loosened up just a bit. When I installed last year, the bearing was
a sliding fit into the race rather than a press fit. So I took it
apart this weekend and put some light prick punch marks in the race.
That tightened the bearing fit in the race fine. No sign of any
bearing wear at all either.
But I still have a little bit of play, even after tightening the
hub nut a bit more than I usually do - I probably went one cotter pin
setting farther than usual. (Yes, I know there are two cotter pin
holes at 90 degrees.) Don't know where the play is - seems like
everything fits together smooth but snug.
Putting various feeler gauges in the rotor-caliper gap indicates
that the total play at the rotor edge is 0.006. I can see it and
feel it when I torque the rotor back and forth, and it's more
noticeable with a wheel on of course.
Is this a lot of play, or is it normal and not worth being
concerned about? I sure can't feel it in the handling, I just don't
want to smoke a wheel bearing because something's not right.
Thanks for any info/suggestions -
