description

This crankshaft is the core rotating component of heavy-duty C15 diesel engine. It is forged from high-strength alloy steel in one piece with integrated counterweights. Main and rod journals are induction hardened and fillet rolled, with full internal oil galleries. Stress relief, MPI crack inspection, journal precision grinding and dynamic balance test are finished before delivery. C15 engines are widely installed on 740 articulated trucks, 374, 385 excavators and high-power generator sets under cyclic heavy impact load. The one-piece design eliminates loose counterweight bolt failure, it is a popular overhaul spare part for C15 powertrain.

Part number: 461-3043
Alternative name: Crankshaft GP
Fit engine: CAT C15 diesel engine
Fit machine: 374, 385 series excavator, 735, 740 articulated mining truck, high-power industrial generator set

Advantages

1. One-piece forged steel without separate counterweight bolts, removes risk of loose or falling counterweights.
2. Fillet rolling reduces stress concentration and improves fatigue fracture resistance.
3. Uniform hardened journal layer resists wear and pitting for mining impact duty.
4. Internal oil galleries deliver stable oil flow for main and connecting rod bearing lubrication.
5. Factory dynamic balance reduces vibration and protects damper, oil seals and timing gears.
6. Compatible with multiple C15 construction variants, widely stocked for overseas mining fleets.

FAQ 

Q1: Can 461-3043 fit 3406E engine directly?
A1: Not interchangeable. 3406E and C15 differ in stroke, crank throw and flange. Verify engine serial number.
Q2: Can journals of this crank be reground after wear?
A2: Check remaining hardened layer depth first. Regrinding is allowed only if sufficient hard layer remains.
Q3: Must timing gear be replaced together with crankshaft?
A3: Inspect gear teeth. Replace if pitting, cracks or chipping are found.
Q4: How to store the crankshaft for long term?
A4: Coat journals, flange and sealing surfaces with anti-rust grease, support on multi-point fixture to avoid bending.
