FAQ

Q1: How do I confirm this oil pump fits my specific Xinchai engine?

A: Check your engine’s identification plate for the model number (e.g., 490BT or 495BT). Verify the existing part number (490B-31000 or 490B-31000A) on your old oil pump. This pump is a direct replacement for these specific models. If your engine is a different variant, please contact us with your engine serial number for cross-reference.

Q2: What is the recommended installation procedure and maintenance interval?

A: Installation should be performed by a qualified diesel mechanic. Ensure the gear housing is clean and lubricate the gears with engine oil before installation. Torque mounting bolts to manufacturer specifications. We recommend inspecting the oil pump during major engine overhauls (typically every 2000-3000 operating hours) or if you notice a drop in oil pressure.

Q3: What should I do if the oil pressure is low after installation?

A: First, check that the oil pickup tube is properly sealed and submerged in oil. Verify the oil filter is not clogged and that you are using the correct oil viscosity. If pressure remains low, inspect the pump for debris or damage during installation. If the issue persists, contact us with your order number and engine details for warranty support.
