M113 Oil pump assembly internal cleaning
Im doing the rebuild of the engine and want to have a look in the oil pump. To see the addition wear and condition of the pump. The pump is in 3 parts with 2 gearhousings. Hold together with 4 M6 bolts. The pump has no gaskets. It has a machined surface with the steel gears inside
The first gear section are the same outside diameter. But the height is a little less then the second stage. The pump internals are not really having any wear only on 1 side of the gears the look like polished. this is where the gear tooth are touching each other, and how the gears are turning each other
i cleaned everything and put it back together. The bolts are put back on torque. 14,7 nm
for any questions just ask
