Replacing an air dryer is more than just swapping a part; it's about system maintenance. When installing your new Sinotruk howo parts WG9000360417, keep these field-tested tips in mind:
Full System Purge: Before installation, bleed all air tanks completely. Check for excessive oil or water in the drained fluid; if there's a lot of oil, your compressor may also need a service.
Verify the Heater Connection: The WG9000360417 features an integrated 24V heater. Ensure the electrical plug is clean and securely fastened to prevent the purge valve from icing up during winter operations.
Check the Governor Setting: This unit often includes an integrated governor. Ensure it is calibrated to cut out at the correct pressure for your specific HOWO model (usually around 8.1 to 8.5 bar).
Sealing Integrity: Use a light coat of grease on the O-rings, but avoid getting any lubricants inside the air ports. Use professional-grade thread sealant sparingly on the fittings.
Initial Cycle Test: After startup, let the pressure build until the dryer "blows off" (the purge cycle). This confirms the unit is functioning and the desiccant is ready for duty.
