SERVICE INFORMATION; Piston Replacement on VG33E Engines
Moly-Coated Piston Skirt Applied To # 3, # 4, # 5
Engines built before VG33-424030M (installed in the WD22, D22 and V41 series) and all VG33E engines installed in the R50 series used a non-coated
piston in cylinders # 1, # 2, # 5 & # 6. If it is necessary to replace a piston(s) in one of these Applied Vehicles, install non-coated pistons of the
appropriate grade into cylinders # 1, # 2, and # 6. Install moly-coated pistons of the appropriate grade into cylinders # 3, # 4, and # 5. Refer to Figure 1
for cylinder locations.
NOTE:
Coated pistons are designed to use a tighter piston-to-bore clearances than non-coated pistons to reduce noise and prevent scuffing.
