The ISUZU 6WG1 crankshaft is the main rotating part of the 6WG1 diesel engine. This model, produced as an aftermarket replacement for OEM numbers 1-12310715-2 and 8-98172014-0, is made from forged steel 42CrMo. It is widely used in heavy-duty machines such as Hitachi ZX450/470 excavators, John Deere 450DLC loaders, ISUZU Giga trucks, and inland marine engines.

Why Choose This Crankshaft

 

Customers look for three things in a crankshaft: strength, accuracy, and long service life. Our ISUZU 6WG1 crankshaft is built with all three in mind. Forged 42CrMo steel gives the shaft higher tensile and fatigue strength than cast iron. Journals are polished until the surface feels smooth to the touch, cutting friction and extending bearing life. Heat treatment follows three stages-quenching, induction hardening, and tempering-so the surface hardness reaches HRC 52–58 with a 3–5 mm hardened layer. This makes it strong enough for long hours in construction and transport work.

Quality Control

 

No shaft leaves our factory without inspection. Engineers record over 30 checks per piece:

  • Dimensional accuracy (journal roundness ≤0.005 mm)
  • Ultrasonic inspection for internal cracks or inclusions
  • Hardness testing to confirm the 52–58 HRC range
  • Dynamic balance with residual imbalance ≤10 g·cm/kg
  • Visual check for coating, scratches, and rust protection

Packing & Shipping

 

Each ISUZU 6WG1 crankshaft is treated with rust-preventive oil, fitted with plastic journal caps, and packed in plywood boxes. For in-stock models, dispatch can usually be arranged within 3–5 working days. Bulk and custom runs follow production planning, but we aim to keep lead times shorter than industry norms.

FAQ (Answering Common Questions)

 

Q: Is this the original ISUZU 6WG1 crankshaft?

A: No. It is an aftermarket crankshaft, but all sizes match the OEM drawings, so it can be fitted directly without modification.

Q: What makes forged 42CrMo better than cast iron?

A: It offers higher tensile strength and toughness. In real use, it lasts longer and is less likely to crack under heavy load.

Q: Can I buy just several items for testing?

A: Yes, we accept trial orders. Many customers start with a small batch before buying in bulk.

Q: Do you provide inspection certificates?

A: Yes. We can supply in-house test reports or arrange a third-party inspection upon request.

Q: How do you ship overseas?

A: Standard packing is export plywood cases with oil coating. We usually send by sea.
