CG125 motorcycle oil pump assembly, covering ZT-CG-0234 (with support), 0235 (shell), 0236 (gear) and other styles, fully match with different versions of CG125 engine lubrication system, directly replace the original oil pump without modification; Adopt gear type pump oil structure, pump oil pressure is stable, sustainable for the engine internal (crankshaft, connecting rod, etc.) components to provide sufficient clean oil, avoid dry friction and wear; The gear is made of high strength engineering plastics, and the shell/bracket is made of alloy, which is resistant to sun and oil corrosion, and suitable for long-term high-load working environment of the engine. The corresponding style is directly assembled in the corresponding position of the engine lubrication system, and the fixed parts can be tightened (it is recommended that professionals install to ensure the accuracy of the pump oil); Stable oil supply can greatly reduce the wear of internal components, which is the key component to ensure the long-term stable operation of the engine.
