www.changlin.com.cn Make sure the o-ring seals for the fill orifice (A) and pilot (B) are correctly installed on the fuel injection pump and are not damaged. Lubricate the mounting flange with clean 15W-40 engine lubricating oil. If the pilot o-ring (B) has a colored stripe, it cannot be reused. When installing a new striped o-ring, lubricate only the gear housing bore, not the o-ring. Caution: The fuel pump drive gear inside diameter and the shaft outside diameter must be clean and dry before installing the pump. A non petrolium based cleaner should be used to clean the drive gear and shaft mounting surfaces. Failure to do so will result in gear slippage in the retarded direction. NOTE:
The oil feed o-ring (A) for PES. P fuel injection pump will be located in the gear housing. Slide the pump shaft through the drive gear and position the pump flange onto the mounting studs. Use your fingers to tighten the mounting nuts. Use your fingers to tighten the capscrews for the support bracket. 113 / 149 pages
