PLATE AS 2077752 - Caterpillar

ACTION REQUIRED
If the final drive has elevated iron/copper and/or debris on the magnetic plug, remove the hub cap to inspect each final drive.
If excessive spline wear between the first reduction carrier and the 2R sun gear is present, the carrier will need to be replaced. Excessive spline wear is determined if flakes are present on the mag plug and splines display wear to the point where material is chipping/rolling on the edge.
Hub replacement is determined via inspection with the same criteria as the carrier, at the time of carrier replacement and will be claimable as needed.
Reference UENR1065 for the "Disassembly and Assembly: 789D and 789D XQ Highway Trucks Power Train" for this work.
