This service manual is a guide to servicing of Mitsubishi forklift trucks of 1.0 ton, 1.25 ton and 1.5 ton (FB10KRT, FB12KRT, FB15KRT) models. The instructions are grouped by systems to serve the convenience of your ready reference.

Do not operate this truck unless you have read and understand the instructions in the SERVICE MANUAL.

The hydraulic pump is a gear pump, driven by a pump motor. The drive gear 2 is splined to the armature shaft of the pump motor.

With a high-pressure gear pump, oil tends to leak from the high-pressure side to the low-pressure side through clearances at the ends of each pump gear (internal oil leakage). This leakage reduces pumping efficiency (or pump’s volumetric efficiency).
In order to prevent the internal oil leakage, this hydraulic pump is designed to direct a portion of pump delivery oil to the back of the bushings 4 and 5. The oil pushes the bushings against the ends of the gears 2 and 3, thus minimizing the clearances between the gears and bushings (see the drawing above). This design can ensure high pumping efficiency for an extended period of time by making up for the clearances as the bushings and gears wear.
