NOTES FOR DISASSEMBLY
DISASSEMBLY OF TIMING TOOTHED-BELT
(1)
Record the rotation direction of toothed-belt for correct re-
mounting.
Notes:
Adhering of water or grease to the toothed-belt will sharply
shorten its service life. So, after disassembly, try your best to
avoid the toothed-belt, toothed-belt wheel and tensioner from
being contaminated and adhered by water or grease. No need to
clean these parts. Replace it if it is seriously contaminated.
In case water or grease is found on these parts, check the front cover
oil-seal, camshaft oil-seal and water pump if there exist leakage.
DISASSEMBLY OF OIL PUMP TOOTHED-BELT
WHEEL
(1)
Assemble the cock on the cylinder block.
(2)
Insert a cross point screwdriver of 8mm diameter to fasten
the balancing shaft on the left side.
(3)
Disassemble oil pump toothed-belt wheel nut.
(4)
Disassemble oil pump toothed-belt wheel.
DISASSEMBLY OF CRANKSHAFT BOLT
(1)
Fasten the flywheel with special tools.
