scope:

This valuable shop reference guide describes in detail ATA's TMC Recommended Practice for adjusting heavy-vehicle wheel bearings (RP 618, Wheel Bearing Adjustment Procedure).The wall chart describes a consistent method of achieving a verifiable wheel bearing end play of 0.001" to 0.005" (0.025 mm to 0.027 mm).The procedure applies to steer, drive, and trailer- axle assemblies using conventional double-nut or single-nut systems. If your maintenance operation wants to prevent premature wheel end component failure and increase seal and bearing life, this reference is a must. Size: 24" x 36"
