Dismantling
The combined parts of the water pumps are detailed in the table of system components and parts information
1. Counterclockwise dismantling of 4 x M6 x 30 hexagonal flange bolts (environmentally friendly coloured zinc) on the
pump cover using a torque spanner (or Air Screw) and an extended hexagon socket - 8# and remove the pump cover
O-ring,
φ11.5 × φ1.8 EPDM O-ring and two φ8 ×14 hollow locating pins.
2. Use a word screwdriver to limit the water pump shaft one groove, use a 12# spanner to rotate clockwise to
loosen the water pump blade and remove it, take out the water seal dynamic ring and rubber.
Press the water pump shaft out, use a screwdriver to reach through the bearing hole to contact the water seal,
then slowly tap the water seal out.
Use a screwdriver to pry out the two oil seals and tap out the bearings to complete the pump disassembly.
(Note:
It is not recommended to disassemble the water pump and its internal bearings, oil seals and water seals
when the pump is running normally and without faults. The water pump shaft thread is a left-handed
reverse thread.)
