To ensure optimal performance of your Sinotruk howo parts, please adhere to the following installation guidelines:
-
Compatibility Verification: Ensure the gearbox model matches the "Fine Teeth" specification. Do not mix fine-teeth shafts with standard-teeth countershaft gears.
-
Lubrication: Pre-lubricate the splines and gear teeth with heavy-duty transmission oil (API GL-5 grade recommended) before installation.
-
Bearing Inspection: Always inspect or replace the input shaft pilot bearing and main shaft bearings to prevent axial play.
-
Seal Integrity: Replace the front oil seal during assembly to prevent gearbox fluid leakage.
-
Alignment: Use a professional alignment tool to ensure the input shaft is perfectly centered with the clutch pressure plate and flywheel.
