Water pump(pump) MTZ (240-1307010А-02)with the pulley

Water pump MTZ-80, MTZ-82 and their modifications on the device and principle of operation similar to the pump 260-1307116-M installed on the tractor MTZ-100 MTZ-102. The pump takes from the bottom radiator tank of chilled liquid and produces its feeding into the cooling jacket of the engine, wherein the heated liquid is displaced from it into the upper tank.

Copious vapor, water leakage or oil in the system, as well as increased noise and knocking are signs of a faulty pump. In addition, the volume of the working fluid is significantly influenced by the degree of wear of impeller blades, the wall of the housing and seals of the pump. Pump 240-1307010-And must be replaced or repaired when detected in his body cracks. The replacement may be subject to worn bearings and seals cushion and cuffs. If the axial displacement in the bearings of the roller is more than 0.6 mm, the cushion is also replaceable. The pump bearings should be lubricated every 60 hours of operation, while the bearing cavity is filled with grease until it appears from the inspection bore.

Mechanical seal impeller should be checked for their technical condition. Textolite washer seals may have signs of wear and ring mark to a depth not exceeding 0.5 mm, the thickness of the washer shall not be less than 2.5 mm. the Cuff should be no through breakthroughs. If after assembling the pump, the cuff is set by the direction of the flaps with springs in the side bearing. Tightening torque of hub nut must be 16-19 H-m pre-assembled roller pump should freely, without jamming the impeller to rotate by hand.
