This is...Includes valve plates, valves, and gaskets. Poor performance, or does air leak out of the intake air filter while the unit is running? This is probably the problem. Damaged/sticking valves is a common issue when you have low compression, and can also cause the motor/engine to stall and too much pressure in the pump’s crankcase. Be sure to clean the head and cylinder very well so as to remove all of the old gasket material and build-up (carbon and rust) when re-installing.... [+] | $196.93 | | | - |

If there are only surface deposits of aluminum from the...If your crank is grooved, replace it to ensure that your rebuild will not be in vain. If there are only surface deposits of aluminum from the bearings, then remove them with a soft wire brush and then polish your crank. The crankshaft translates rotational motion to reciprocating motion in a compressor pump. A crankshaft has “journals”, where the connecting rods ride on. A crank can be damaged by running the pump too low on oil, or if the drive belt is too tight. Make sure the output shaft (where the pulley installs) is not warped, and if you hear knocking, stop the unit immediately and disassemble the pump. When conrods seize onto the crankshaft, the journals must be polished of all aluminum (or iron) deposits before new conrods are installed. If pitted deeply, the crankshaft must be replaced....
