it on blocks, or in workbench with appropriate size
mounting hole cut into it. Be sure unit is facing

planetary gear and into pilot bushing in output
shaft. Be sure tool bottoms against planetary

drive case (Fig. 172). Then position Dial Caliper
C-4962 over gauge tool.

through gauge tool slot until scale contacts end of
Gauge Alignment Tool 6312. Lock scale in place.
Remove dial caliper tool and note distance mea-
sured (Fig. 172).
