Prior to performing any service, reference the Disassembly and Assembly Manual.
RENR8328 - 789C, 793B and 793D Off-Highway Trucks Power Train
KENR8397 - 793F Off-Highway Truck Power Train

Replace the former 214-1555 Pump Group with a new 341-4837 Pump Group. The new pump has an improved seal package for use with a wet sump and an added breather plug to reduce external contamination.

In addition, Group 2 may have a missing or mis-assembled seal on the 233-4670 Tube. This is part of the 193-6223 Pump and Motor Group-Rear Axle Lube. The 233-4670 Tube should be inspected to ensure (2) 061-9455 Seals are installed.
