Confirm fitment: Ensure 1014400908 matches your engine model (WP15NG, WP13, etc.).
Inspect new unit: Check for dents, cracks, or deformation — especially around the flange.
Clean engine block surface: Remove old gasket residue, dirt, or oil sludge completely.
Verify accessories: Have new gasket (1001799606), drain plug, and washer ready.
Position the Oil Pan: Carefully align the oil pan with the engine block's lower face.
Install Gasket: Place new gasket (1001799606) evenly without twisting.
If using liquid sealant (e.g., Weichai RTV), apply thin bead (~3mm) only where specified.
Insert Bolts: Start all mounting bolts finger-tight to ensure even alignment.
Torque Sequence:
Tighten bolts in a crisscross (diagonal) pattern
Use calibrated torque wrench
Final torque: Typically 18–25 N·m (confirm exact value per service manual)
Apply multiple stages (e.g., 50% → 75% → 100%) to avoid warping
Install Drain Plug: Insert with new copper/composite washer; torque to 35–45 N·m
Refill Engine Oil: Add recommended grade and quantity per engine specs.
Leak Test: Run engine for several minutes, then inspect entire oil pan seam for seepage.
