to ensure that the lubricating oil in the crankcase can be
discharged quickly and completely. When replacing,
place an oil pan under the engine and unscrew the oil
bolt A to release the lubricating oil. Check the plug
gasket for damage, and replace it with a new one if it is
damaged. When the lubricating oil is completely
discharged, install and tighten the oil drain bolt and

REMOVAL AND INSTALLATION OF
OIL PUMP
The two-stroke oil pump is related to the effective
lubrication of the engine piston, cylinder block,
crankshaft and other thermal parts, so the inspection of
the oil pump is particularly important.
The lubrication of the heat engine part of the KT250
model engine must be a special two-stroke engine oil
by mixing gasoline into a special burning oil. Adjust
the opening of the oil pump according to the throttle to
mix a proper proportion of the burning oil. A proper
proportion of combustion oil can lubricate the piston,
cylinder block, crankshaft, connecting rod, etc., and
effectively protect the engine.
When disassembling the oil pump, first remove the oil
pump cover on the right cover of the engine, and then
remove the two fastening screws of the oil pump to
remove the oil pump. When reinstalling, install it in the
reverse order of the removal.
NOTE
: The tightening torque of the oil pump screws is
5N.m.
