LS 460 RWD V8-4.6L (1UR-FSE) (2010)
(e) Using a dial indicator, measure the commutator runout.
Maximum commutator runout:
0.05 mm (0.0020 in.)
(f) If the commutator runout is more than the maximum, correct it using a lathe.
(g) Measure the undercut depth of the commutator.
Standard undercut depth:
0.7 mm (0.028 in.)
Minimum undercut depth:
0.2 mm (0.008 in.)
(h) If the undercut depth is less than the minimum, correct it with a hacksaw blade.
3. INSPECT STARTER YOKE ASSEMBLY
(a) Inspect the resistance of the field coil.
(1) Measure the resistance between the lead wire and field coil brush lead.
Standard resistance:
Below 1 Ohms
(2) If the result is not as specified, repair or replace the yoke assembly.
