ME8200, ME9000, WSM

(6) Hydraulic Pump for Three Point Hydraulic System

IMPORTANT
• The hydraulic pump is precision machined and assembled : if disassembled once, it may be unable to
maintain its original performance. Therefore, when the hydraulic pump fails, replacement should be
carried out with the hydraulic pump assembled except when emergency repair is unavoidable.
• When repair is required, flow the disassembly and servicing procedures shown below with upmost care.
• Be sure to test hydraulic pump with a flowmeter before disassembling.
• After reassembly, be sure to perform break-in operation and ensure that there is nothing abnormal with
the hydraulic pump.
Removing Hydraulic Pump (ME8200)
1. Disconnect the delivery pipe (1), (2) from the hydraulic pump.
2. Disconnect the suction pipe (3), (4) from the hydraulic pump.
3. Remove the hydraulic pump assembly mounting screws and
nuts.
