②if the measured cylinder pressure
is lower than the normal value, pour a small amount of clean engine oil from the spark plug,
turn the crankshaft a few times, so that the piston ring and cylinder wall are evenly covered with oil film, and retest the cylinder
pressure. If the cylinder pressure measured after pouring oil is greater than the last cylinder pressure value, please dismantle the
machine and check the piston and piston ring.
5. Use the spark plug tool to install the spark plug in place and tighten it with a fixed torque (fixed torque: 14±1 N.m
).

Assembly
1. Remove 3 m6×30 hexagonal flange bolts counterclockwise with a torque wrench (or air batch) and an extended outer hexagon
socket -
8#, remove the water pump from the engine, and then remove the φ36×1.9 acrylic o
-type ring, 18.2×2.4 EPDM O-ring
and two φ8×
14 hollow positioning pins.
2. Use a torque wrench (or air batch) and an extended outer hexagon socket
-8# Assembly 4 m6×22 hexagonal flange
full-threaded bolts and 1 m6×10 top pin bolt (zinc
) on the water pump cover counterclockwise. Zinc), remove the
water pump
cover, water pump cover sealing ring, 2 copper gaskets and 2 φ8×14 hollow positioning pins.
3. Use a 12# wrench to rotate counterclockwise to loosen and remove the water pump blade, and take out the water seal moving
ring ceramic and water seal moving ring rubber.
Take out the water pump shaft, use a flat-blade screwdriver to extend from the bearing hole until it contacts the water seal, and
then tap it slowly to knock out the water seal.
