Main Pump (Kawasaki)
Oil filling and Air Venting
Cautions During Starting Operation
1. Check pipings for proper installation.
2. Check that the rotating and suction / delivery directions are correct.
3. Before starting the prime mover, make sure the pump free of any load.
4. After starting, continue the idling for a while to vent air completely from the circuit.
5. Check the pump and pipings for oil leaks and abnormal vibrations.
6. When the pump is attached to a gear box, check that the box is full of oil to its proper level.
TROUBLESHOOTING
General Cautions
This section describes the countermeasures to be taken if any abnormality is detected during the operation
of the Kawasaki swash plate type axial piston pump.
The general cautions are as follows:
1. Consider the condition before starting work.
2. Judge the nature of the abnormality, before starting work. Especially, judge if it is a problem in the
circuit or caused by the regulator or attached valves and determine that something is truly wrong with
the pump or not.
3. Read and understand the maintenance manual before disassembling and follow the right
disassembling procedures.
4. Even when any section is to be disassembled, not to make dust or let it enter into the pump.
5. Since the parts are finely finished, handle them carefully to prevent damage.
Check Pump Proper for Abnormalities
The pump is often fitted with a regulator, accessory valves and associated pump. It is very difficult to find
the cause of the failure. Investigate the following items, and the abnormal point will be revealed.
1. Check filter and drain oil
Check filter elements for excessive amount of abnormal impurities. Since the shoes and cylinder may
give off worn metal particles, a small quantity may be detected there. However if a excessive amount
of metal particles is found in the filters, it should be considered that shoes may be damaged.
Similarly, check drain oil in the pump casing.
2. Existence of abnormal noises or vibrations
Item Caution
Applied
Type
Oil filling. Fill the pump casing with oil. Inside the pump there are high-
speed sliding and moving parts, such as bearings, pistons/
shoes, retainer, etc. If not filled with oil, these parts may suffer
some serious problems, such as seizures damage. All types.
Air venting. When air is left in the circuit or pump, it may cause a malfunction
or damage. Completely vent air. All types.
