MORTCH oil pump for 49-50cc two-stroke JOG Minarelli engine

Oil pump for 49/50 cc two-stroke engine

A standard oil pump designed for the popular family of JOG Minarelli two-stroke engines of 49-50 cc, factory-marked 1E40QMB or 1PE40QMB. This engine type is fitted to many brands and models of scooters, mopeds and small off-road vehicles, so the pump has a wide range of service uses.

Function of the oil pump

The oil pump is responsible for precisely metering oil into the fuel mixture in a two-stroke engine, which is crucial for proper lubrication of the cylinder, piston and crankshaft bearings. A faulty or worn pump is one of the most common causes of overheating and premature wear of a two-stroke engine.

Application and compatibility

The part fits directly as a replacement for the original pump marked JOG 3KJ-13100, installed in JOG type engines used in scooters, mopeds, mini quads and mini choppers with a 49/50 cc drive.

Material and build

The pump is made of metal, as a compact module mounted inside the engine housing and mechanically driven from the crankshaft.

When to replace the pump

Replacement is recommended when there are symptoms of insufficient engine lubrication, such as excessive smoke, loss of power or unusual engine knocking - especially if other causes have been ruled out.
