FAQ

Q1: How do I confirm this 4TNE82 crankshaft fits my engine?
A: Verify your engine model number matches “4TNE82” exactly. For Komatsu engines, check the nameplate on the valve cover or engine block. Measure the crankshaft journal diameters and overall length against your existing part. If possible, compare the casting numbers on your old crankshaft with our specifications. Our technical team can assist with cross-referencing if you provide your engine serial number.

Q2: What installation precautions should I take?
A: Professional installation is recommended. Ensure the crankshaft is clean and free of shipping preservatives before fitting. Check main bearing clearances using plastigage, and torque all bolts to manufacturer specifications. Replace main and rod bearings simultaneously for optimal performance. After installation, verify crankshaft end-play and rotate the engine by hand to confirm smooth operation before starting.

Q3: What maintenance extends crankshaft life?
A: Regular oil changes with the correct viscosity grade are critical, as oil starvation is the primary cause of crankshaft failure. Monitor oil pressure consistently and address any drops immediately. Avoid engine lugging or over-revving, which can induce torsional stress. Inspect the harmonic balancer (if equipped) for deterioration, as a failed balancer can transmit damaging vibrations to the crankshaft. Periodic bearing inspection during major overhauls helps detect early wear patterns.
