EPA07/10 DD PLATFORM WORKSHOP MANUAL - ENGINE 18. The dial indicator should read 0.051 - 0.257 mm (0.002 - 0.010 in). If the gear lash is excessive between either camshaft gear and the number five idler gear, inspect the number five idler gear spindle, camshaft gear and camshaft housing. Repair as necessary. NOTICE: The camshaft journal area is lubricated by oil that has to travel through the rocker shaft. If the rocker shaft is installed incorrectly, oil passages do not line up. This results in insufficient lubrication and damage to the camshaft journals. Incorrect shaft installation may also result in the engine brakes not functioning and cause damage to the rocker arm bushings.
