New Piston and Liner Components Are Available For Certain G3516H Engines {1214, 1215, 1216, 1222, 1239}

Usage:

Engine: G3516H (S/N: GLM1-UP; GLN1-UP)

New cylinder packs are being made available for certain G3516H engines. Adding these parts to the engine has the potential to increase electrical efficiency.

Table 1 contains the part numbers needed to update one cylinder. When updating a cylinder all of the parts listed must be changed at the same time.

Note: All cylinders do not need updated at the same time. Engines can be run with new cylinder packs and previous cylinder packs both installed.
