Operation Manual
Lubrication
The powerend is lubricated via 80W90 gear
oil (non detergent only) in the sump of the
housing. The journal bearings, crossheads,
and connecting rod bushings are supplied oil
via gravity from a collection trough above the
crossheads. The powerend has a level require-
ment to ensure oil lubricates the crank- shaft
tapered roller bearings and stays in con-
tact with the crankshaft. Front to back level
specication is 7° and side to side level is 10°.
Both a low oil level shutdown and a high oil
temperature shutdown are available as op-
tions.
The powerend oil has a recommended maxi-
mum temperature of 190°F and can be com-
fortably run in most environments. Extremely
hot or cold envi- ronments (i.e. Middle East,
Canada) may require oil cooler or synthetic oil.
