In Cummings diesel generating sets in the operation, low oil pressure unit of the transmission components will cause poor lubrication, if the circuit block will appear, holding cylinder scuffing, bearing clearance is too large, directly affect the normal use of the Cummings diesel generating sets. Cummings diesel generating sets of low oil pressure in the main and the following aspects associated with:

1, Oil cooler cooling system radiator core blockage; external void blocked.

2, The use of maintenance: Engine overload; oil change on time, to ensure the correct use of oil filter. Only according to the correct maintenance to ensure the normal use of the unit.
 
3, Dirty lubrication system oil filter; oil suction pipe is blocked; oil pressure regulator failure.

4, Mechanical adjustment and repair of the bearing clearance; improper engine overhaul; need; or main bearing connecting rod bearing damage.
