Need the DAEWOO D2366 crankshaft (150107 00187) without the factory wait?

We supply 40Cr forgings-each batch sourced from a top-500 Chinese mill and formed with our own tooling-then finish-machine, induction-harden and dynamically balance the DAEWOO D2366 crankshaft in-house. The shaft drops straight into Doosan/Develon excavators, delivers the same fatigue life as the original, and ships from stock in days instead of weeks, cutting both downtime and cost.

Product Advantages

(1)Material Advantage – Forged Steel 40Cr

Using 40Cr forged steel, the crankshaft is designed to last. It performs far better than cast iron alternatives, with strength levels that keep it from bending or cracking under pressure. In real working conditions, customers typically see 3–5 years of reliable service, even in demanding operations, helping reduce maintenance stops and unplanned downtime.

(2)Multi-Stage Heat Treatment for Durability

Tempering → Medium-Frequency Induction Hardening → Stress-Relief Tempering
Hardened layer depth: 3–5 mm
Surface hardness: HRC 52–58
Delivers the optimal balance of core toughness and surface wear resistance

(3) Precision Journal Grinding

CNC machining achieves Ra ≤0.4 μm surface roughness and ≤0.005 mm roundness
Enhances lubrication film stability, reduces friction, and minimizes early wear
Ensures smooth engine operation when paired with dynamic balancing

(4) Stringent Quality Control

Over 30 inspection steps from forging to final packaging
Includes ultrasonic testing, magnetic particle inspection, and dynamic balance checks
Optional third-party certificates available for hardness, balance, and tolerances

150107 00187 ISO certification

Application

FAQ (Answering Common Questions)

Q: How close are the journals after you grind them?

A: We stop the wheel when the air gage reads 0.005 mm out-of-round and the stylus says Ra 0.4 µm

Q: Got proof of quality?

A: Sure. We can e-mail you a third-party sheet that lists hardness, balance runout, and induction-hard depth-same lab that audits us twice a year.

Q: How long before I'm back under the cab?

A: Most customers get three to five years of 10-hour shifts before the first signs of wear.

Q: Will it take the torque spike when the bucket stalls?

A: No drama. The shaft is forged from 40Cr, heat-treated, and spin-tested to handle the engine's peak without twisting the keyway.
