REPAIR COOLING SYSTEM. Disassembly, inspection and assembly of liquid pump
The design of the liquid pump is shown in Fig. 48.
Roller liquid pump rotates in two ball bearings
having a special on both sides
seal, which ensures retention of the lubricant
at the time of the pump overhaul
engine. Special lubricant is laid
in the bearing during assembly at the factory and
no additional lubrication during operation does not
is required. In the body of the pump shaft is sealed against the penetration of
Water featuring self-cuff, consisting of a washer
Lead-graphite composition, the rubber seal
and springs. To protect the ball from falling
water in them, accidentally leaked through the seal roll in
bottom of the case predusmorteno special drain.
The appearance of a leak of fluid from the drain holes in the
the operation of the engine indicates a fault
seal. In this case, razbborka liquid pump.
Removing the leak by closing the drain
not be allowed to avoid damage to bearings due to washout
lubricant. Liquid pump disassembly
produce in case of wear of ball bearings to replace them.
Disassembly make in the following sequence:
- Unscrew the bolt and compress with the impeller
impeller shaft with a special remover;
- Raskontrite nut clamp screw and remove the ball bearing
- Hold the front end of a liquid pump in a special washer
with a hole through which passed a ball, and hit
hammer on the mandrel, stubborn to the rear end of the roll, shake
roller ball out of the case ....
