5. DISASSEMBLING AND ASSEMBLING

[1] HYDRAULIC PUMP

IMPORTANT

• The hydraulic pump is precision machined and assembled: if disassemble once, it may be unable to keep

its original performance. Therefore, when the hydraulic pump fails, replacement should be done with the
hydraulic pump assembled except when emergency repair is unavoidable.

• When repair is required, follow the disassembly and servicing procedures shown below with utmost care.
• Be sure to test the 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.
