(c) Check the commutator circle runout. (1) Place the armature shaft on V-blocks. (2) Using a dial indicator, measure the circle runout. Maximum runout: 0.05 mm (0.00197 in.) If the circle runout is more than the maximum, replace the starter armature assembly. (d) Using a vernier caliper, measure the commutator diameter. Standard diameter: 29.0 mm (1.14 in.) Minimum diameter: 28.0 mm (1.10 in.) HINT: Be sure to measure the commutator diameter at the ridges. If the diameter is less than the minimum, replace the starter armature assembly. Standard undercut depth: 0.4 mm (0.0157 in.) Minimum undercut depth: 0.2 mm (0.00787 in.) HINT: Be sure to measure the commutator undercut depth at a cutout. If the undercut depth is less than the minimum, increase the depth using a hacksaw blade. 4. INSPECT STARTER BRUSH HOLDER ASSEMBLY (a) Using a vernier caliper, measure the brush length. Standard length: 14.4 mm (0.567 in.) Minimum length: 9.0 mm (0.354 in.) HINT: Be sure to measure the brush lengths at the protrusions. If the length is less than the minimum, replace the starter brush holder assembly. 3UR-FE STARTING: STARTER: INSPECTION; 2015 MY Tundra [08... |
