Drive Gears

Cleaning

Clean gears in solvent and dry with compressed air.

Inspection

Inspect gear teeth for concerns such as scores and nicks. Note condition of tooth contact pattern. If teeth are scored, replace gears.

Check drive gear backlash. Refer to Drive Gear Backlash (All Gears) in the Service Procedures portion of this section.

It is not necessary to replace gears in sets. Replace damaged gears and check backlash, runout, etc., to determine if any other gear should be replaced.
