Parts for Caterpillar 3412B – Crankshaft Section

The crankshaft system is the foundation of power delivery in the Caterpillar 3412B engine. Every rotation of the crankshaft translates piston movement into usable horsepower, making it one of the most critical components in keeping your equipment running at peak performance. To support reliable engine operation, Diesel Pro Power supplies a full range of premium aftermarket crankshaft components for the 3412B—including new crankshafts, gears, bearings, seals, dowel pins, thrust washers, and vibration dampers.

Complete Crankshaft Assemblies for Caterpillar 3412B

We carry new replacement crankshafts engineered to meet Caterpillar specifications for strength, durability, and balance. Both standard and wide bearing designs are available, ensuring compatibility with different 3412B configurations. Each crankshaft undergoes precision machining to deliver smooth operation and long service life.

Crankshaft Gears for Caterpillar 3412B

The crankshaft gear is a vital link in the timing system, transferring rotation to the camshaft and other driven components. Our catalog includes multiple gear options with different tooth counts, providing the right fit for your engine’s configuration. Manufactured from heat-treated steel, these gears are designed to withstand the heavy loads and constant stress of industrial and marine applications.

Dowel Pins and Alignment Components

Proper alignment of the crankshaft and gear assembly is essential for long-term reliability. Diesel Pro Power supplies precision-fit dowel pins that secure gears in the correct position, preventing slippage, misalignment, and premature wear.

Main Bearings for Caterpillar 3412B

Main bearings support the crankshaft within the engine block, reducing friction and enabling smooth rotation. We provide a full selection of standard and oversize main bearings, allowing for exact fitment during rebuilds and machining work. Options include oversize sets in .010, .025, and .050 increments. Each bearing is engineered for optimal load distribution and oil film retention, ensuring longevity under demanding conditions.

Thrust Washers for Caterpillar 3412B

Thrust washers control axial movement of the crankshaft, preventing excessive forward or backward play that could damage engine internals. Our thrust washers are precision-manufactured for durability and exact fitment. Two are required per engine, and we stock replacements designed specifically for the 3412B and the broader 3400 Series family.

Vibration Dampers for Caterpillar 3412B

A properly functioning vibration damper absorbs torsional vibrations created by crankshaft rotation, protecting the engine from damaging harmonic resonance. Diesel Pro Power provides high-quality dampers that restore balance and stability to the crankshaft assembly, prolonging engine life and reducing stress on bearings, seals, and gears.

Front and Rear Crankshaft Seals

Oil leaks at the crankshaft ends can cause costly downtime and potential engine damage. We supply both front and rear crankshaft seals for the Caterpillar 3412B. These seals are engineered from advanced materials to withstand extreme pressures and high operating temperatures, ensuring reliable performance in both industrial and marine environments.
