Oil pump - Reassembly

Oil pump
Oil pump - disassembly
KOHLER therefore recommends that the oil pump be handled
as an assembly from a service standpoint
KOHLER does not recommend that the oil pump be
disassembled, then reassembled for purposes of installation on
the engine except during emergency situations.
Rotate the crankshaft until the crankshaft timing pulley keyway
is vertical as shown. Remove the oil pump assembly retaining
bolts. When the crankshaft timing pulley keyway is vertical, the
oil pump drive keyway A will be at 3:00 o’clock allowing removal
of the oil pump assembly via relief B.

The engine control components are all on the cylinder head.
The cover contains part of the lubrication duct of the camshaft
and of the rocker arms, as well as part of the engine vent
system.
