MACHINING ROTORS
STEP 3: ADJUST FOR LATERAL Run-out
If the TRY AGAIN light is illuminated, the machine is unable to fully adjust for run-out. This dif-
ficulty could be due to looseness of fittings, irregular run-out, damage to wheel bearings or other
components, or other factors relating to set-up. The best procedure is to loosen the machine from
the adapter, check adapter and vehicle setup, rotate the adapter locator pin 180 degrees, and at-
tach the machine again. Make sure that the machine is adequately supported by the trolley. Run
the adjustment procedure and the machine will again adjust for run-out. If TRY AGAIN appears
repeatedly, there is most often a problem with the vehicle. You should dismount the machine and
check for a damaged wheel bearing or CV joint. Such problems will have to be addressed before
match-machining is possible.
If the machine seems to be having excessive difficulty in adjusting for lateral run-out, consult the
troubleshooting section on Page 33.
