RUNOUT
1: Secure rotortowheel hubwith atleast twonuts (M12 x
1.25).
2. Check runout usingadial indicator.

Make surethatwheel bearing axialendplay iswithin thespec-
ifications beforemeasuring. RefertoFA section ("FrontWheel
Bearing", "ON-VEHICLE SERVICE").
Maximum runout:

3.
If
the runout isout ofspecification, findminimum runout
position asfollows:
a. Remove nutsandrotor fromwheel hub.
b. Shift therotor onehole andsecure rotortowheel hub
with nuts.
c. Measure runout.
d. Repeat stepsa.to c.so that minimum runoutposition can
be found.
4. Ifthe runout isstill outofspecification, turnrotor withon-car
brake lathe("MAD, DL-8700", "AMMCO700and 705" or•••
equivalent).
