FAQ

Q1: How do I confirm this kit fits my specific Xinchai 495BT engine?
A: Please check the engine nameplate for the exact model number (e.g., 495BT or 4D30G31) and the serial number. Compare your current part numbers (especially the cylinder head or block numbers) with the OEM references 495B-04001-1A or 495B-01005B. If your engine uses a different prefix (e.g., 495B-04002), please contact us with your engine details to verify compatibility before purchase.

Q2: What is typically included in this overhaul repair set?
A: This kit generally includes: piston set with rings, cylinder liners, main bearings, connecting rod bearings, thrust washers, and a full gasket set (head gasket, valve cover gasket, oil pan gasket, etc.). Some variations may include oil seals and valve stem seals. For a detailed list of all components in the specific kit you are ordering, please request the packing list before shipment.

Q3: What is the recommended procedure when installing this overhaul kit?
A: Professional installation by a qualified diesel mechanic is strongly recommended. The engine block must be thoroughly cleaned and inspected for cracks or wear. Cylinder bores should be honed to the proper crosshatch pattern. All bearings must be installed with correct oil clearance, and head bolts should be torqued to the manufacturer’s specifications in the correct sequence. After installation, perform a compression test and check for oil pressure before starting the engine. Break-in procedures should follow standard diesel engine guidelines.
