FAQ

Q1: How can I confirm this crankshaft will fit my Yuchai engine?
A: Please check the model number stamped on your engine block. This crankshaft is specifically designed for the YTR4105, YTR4108, and YT4B2 models within the LR4105 series. If your engine number begins with these prefixes, this part is likely the correct one. We also recommend comparing the physical dimensions and the number of counterweights with your old crankshaft.

Q2: Does this crankshaft come with bearings or a thrust washer?
A: This listing is for the crankshaft only (part number YTR4105.040301FE). Main bearings, connecting rod bearings, and thrust washers are typically sold separately. We recommend replacing these components with new ones during your engine rebuild to ensure proper oil clearance and long service life.

Q3: What is the proper installation procedure for this part?
A: Installation should be performed by a qualified diesel mechanic. Key steps include: 1) Thoroughly cleaning the engine block and bearing saddles. 2) Checking the crankshaft journals for any shipping damage. 3) Lubricating all bearing surfaces with assembly lube. 4) Torquing the main bearing caps to the manufacturer’s specified sequence and torque settings. Incorrect installation can lead to premature engine failure. Always consult the Yuchai service manual for your specific engine model.
