- Measure the gear backlash using ST1 and ST2, and then insert the ST2 though the access window of case.
ST1 498247001 MAGNET BASE
ST2 498247100 DIAL GAUGE
NOTE:- Measure the backlash by applying a pinion tooth between two bevel gear teeth.
- Fix the bevel pinion gear in place with a screwdriver or similar tool when measuring.
Standard value: 0.13 - 0.18 mm (0.0051 - 0.0071 in)
- If the backlash is not within specification, select a washer from the table below.THICKNESS CHART
