Genuine Sinotruk HOWO Fuel Filter 612630080087 (CX1023E) for Weichai WP10 & WP12 Engines

The 612630080087 (CX1023E) is a high-efficiency spin-on fuel filter specifically engineered for the Weichai WP10 and WP12 engine series used in Sinotruk HOWO heavy trucks. Given the sensitivity of modern high-pressure common rail systems, this filter provides the necessary 5-10 micron filtration to remove fine particulates and moisture that can lead to injector clogging or pump erosion. As a staple in our Sinotruk spare parts inventory, the CX1023E ensures your engine maintains peak performance even under the harsh operating conditions of long-haul transport.

Pro-Tips for Replacing your CX1023E Filter:

1. Seal Preparation: Before installing the new 612630080087, apply a light film of clean diesel fuel to the rubber gasket. Avoid using grease, as it can cause the gasket to slip or swell incorrectly.

2. Pre-Filling: To prevent airlocks in the common rail system, it is advisable to pre-fill the filter with clean, filtered diesel before spinning it onto the filter head.

3. The Hand-Tight Rule: Spin the filter on until the gasket makes contact with the base. Tighten it by hand an additional 3/4 to 1 full turn. Never use a filter wrench for tightening, as over-torquing will deform the seal and make the next removal extremely difficult.

4. Air Bleeding: Once installed, use the manual priming pump on the engine to purge any trapped air. If you notice a “stutter” on the first start, there is likely still air in the 612630080087 housing.

5. Leak Check: Start the engine and let it idle for 3 minutes. Inspect the base of the CX1023E for any “sweating” or fuel weeping.
