description

This crankshaft is the core transmission component of C18 ACERT engine with integrated counterweights. It is forged from alloy steel blank, quenched and tempered, precision ground on journals, oil passages polished and surface hardened, with dynamic balance test finished before delivery. It withstands high combustion impact load, widely used for overhaul of mining construction machinery, stationary generator sets and industrial pump units under long-time heavy load.

Advantages

• Pitch diameter of the crankshaft gear is 213.66.
• Designed to reduce vibrations and ensure smooth operation.

1. Integrally forged steel blank delivers excellent torsion resistance and fatigue resistance, suitable for mining heavy-load impact conditions.
2. Main journals and connecting rod journals are precision machined with stable wear-resistant layer, slowing bearing wear effectively.
3. Integrally machined and assembled counterweights with factory dynamic balance calibration reduce engine vibration and noise.
4. Built-through lubrication oil passages with reasonable layout ensure stable oil supply at high speed.
5. OE standard dimension for direct replacement, no extra machining required.

FAQ 

Q1: Can 430-2593 crankshaft fit C15 engine?
A1: Not interchangeable. C15 and C18 differ in crank throw and journal dimensions.
Q2: Can crankshaft counterweight bolts be reused?
A2: Reuse is not recommended. These are stretch bolts and better replaced during overhaul.
Q3: Which spare parts should be renewed together with crankshaft?
A3: Main bearings, connecting rod bearings, thrust washers, front and rear crankshaft oil seals and main bearing bolts are recommended.
Q4: What are the requirements for crankshaft storage?
A4: Place it on multi-point support fixture, coat journals with anti-rust grease to avoid bending from single-point stress.
