Camshaft: Testing and Inspection
Runout
1. Set suitable V-blocks on surface plate. Support outer camshaft journals on V-blocks.
NOTE: Check camshaft journals for out-of-round before checking for runout, or an out-of-round condition on the center journal could be
confused for an excess runout condition.
2. Set up D78P-4201-B or equivalent Dial Indicator with Bracketry to check center bearing journal.
3. Zero dial indicator.
4. Slowly rotate camshaft to determine overall runout. If runout exceeds 0.03 mm (0.0012 in.), replace camshaft.
