FAQ

Q: How do I verify that this WP4G95E221 piston will fit my engine?
A: Check your engine’s identification plate for the model number (e.g., WP4G95E221) and compare with the piston part number stamped on your existing component. Measure the piston diameter and compression height if possible. For Weichai engines, the WP4G95E221 designation typically indicates the specific engine variant. Contact our technical support with your engine serial number for cross-reference assistance.

Q: What is included in the piston assembly package?
A: This WP4G95E221 piston includes the piston body with piston rings pre-installed (compression rings and oil control ring). The piston pin (wrist pin) and retaining clips may be included depending on the specific configuration. Please confirm your requirements at the time of ordering. The assembly is packaged in a plastic bag, box, and carton for protection.

Q: What maintenance is recommended after installing a new piston?
A: After installing this WP4G95E221 piston, follow proper break-in procedures: run the engine at varying loads (avoid prolonged idle or full load) for the first 50 hours. Change engine oil and filter after initial break-in. Monitor cylinder compression and oil consumption regularly. Always use the recommended oil viscosity and change intervals specified in your Weichai engine manual. Proper cooling system maintenance is essential for piston longevity.
