This manual provides operation, maintenance, and troubleshooting instructions for Sanlang's KFU2-40, KFU2-B40, KFD, and KFP vehicle chassis centralized…
The manual describes the concept and components of the vehicle chassis centralized lubrication system, including oil pumps, controllers, distributors, pressure sensors and associated piping. It explains how the system supplies timed, measured lubrication to dozens of friction points on buses, trucks and sanitation vehicles to extend vehicle life and improve operational efficiency.
Detailed sections cover component introductions, controller operation, installation and commissioning, routine maintenance, fault diagnosis, oil pump refilling methods, recommended lubricants, and a spare‑parts list. The document is intended for drivers and maintenance personnel responsible for correct system use and repair. This manual is written in Chinese.
| Applicable Vehicles | Bus, Truck, Sanitation Vehicle |
|---|---|
| Maximum Lubrication Points | 60 (KFU2‑B40) / 30 (others) |
| Drive Method | DC12V or 24V electric |
| Oil Tank Capacity | 3.0 L (KFU2‑40) / 1.2–2.5 L (others) |
| Distributor Model | ZXQ or QT86 |
| Control Method | DKQ controller or SL‑ECU controller |
The pump is started and stopped by a DKQ‑type or SL‑ECU‑type controller that sends start/stop commands to the motor.
The system works from –10 °C to +70 °C, and for some models down to –15 °C when using antifreeze grease.
Use NLGI‑0, 00 or 000 extreme‑pressure lithium‑based grease.
Up to 60 lubrication points.
