ENGINE - Engine AssemblyII-67
SERVICE POINTS OF REMOVAL
MllSBDF
32. DISCONNECTION OF POWER STEERING OIL PUMP Disconnect the oil pump with hoses from the bracket.
NOTE
The removed power steering oil pump should be fastened(by using rope, etc.) in a position that will not interfere
with the removal/installation of the engine assembly.
33. DISCONNECTION OF AIR CONDITIONING COMPRESSOR
Disconnect air conditioning compressor connector and re-
move it with hoses from the compressor bracket.
NOTE
The removed air conditioning compressor should be fas-
tened (by using rope, etc.) in a position that will not inter-
fere with the removal/installation of the engine assembly. OlA0177
37. DISCONNECTION OF ENGINE MOUNT BRACKETBefore removing the engine mount bracket installation
bolt, use a chain block or similar arrangement to suspend
the engine assembly (to the extent that there is no
looseness of the chain).
39. REMOVAL OF ENGINE ASSEMBLY After checking that the cables, hoses, harness connec-
tors, etc. are all removed, slowly raise the chain block tolift the engine assembly upward out of the engine
compartment.
SERVICE POINTS OF INSTALLATION MllSDAY
39. INSTALLATION OF ENGINE ASSEMBLY When mounting the engine, check to be sure that thecables, hoses, harness connectors, etc. are all in the
correct position.
