Premier GP-30 Diesel Engine Operating Instructions
Lubrication and Greasing Instructions
The engine should be well oiled and greased in order to run properly.
You should regularly lubricate the engine to prevent it from squeaking. Use
light household oil and follow the lubrication points marked “L” in Fig. 5. Do
not over-oil. Use only a drop or two on each pivot point.
The locomotive’s internal gearing was greased at the factory and should not
need additional grease until after 50 hours of operation or one year, whichever
comes first. Follow the greasing instructions below. Note that in some tightly
packed engines you may need to move internal components temporarily in
order to access the gears.
1. To access the gear box, remove the cab from the chassis by unscrewing the
chassis screws as seen in Figure 6 and lifting the cab from the chassis.
2. Once the body is removed, remove the trucks by unscrewing the black
Phillips motor mount screw located on the underside of the drive trucks (see
Fig. 7 on pg. 13).
