INSPECTION AFTER DISASSEMBLY
Shift Rod Components
• Check the working face of the shift rod and fork for wear, partial wear, bending and other abnormality. If any is found, replace with a
new one.
• Measure the clearance between the shift fork and sleeve. If it is out of specification, replace it with a new one.
Planetary Carrier
• Measure the end play of each pinion gear. If it is out of specifica-tion, replace the planetary carrier assembly with a new one.
• Check the working face of each gear and bearing for damage, burrs, partial wear, dents and other abnormality. If any is found,
replace the planetary carrier assembly with a new one.
