💎 Advantages of Our Premium Brand Crankshafts

• Forged and Nitrided Steel: Unlike cheap castings, our crankshafts undergo nitriding or induction hardening processes on the journals, preventing premature wear.
• Precision Dynamic Balancing: A Cummins or Cat crankshaft is factory balanced to eliminate vibrations that could destroy engine bearings and seals
• Optimized Lubrication Channels: Polished oil holes to ensure constant lubricant flow to every connecting rod under any pressure
• Fatigue Resistance: Capable of withstanding the most violent torsions during engine braking and starts with maximum load on inclines
• Micrometer Precision: Exact journal measurements that allow the main and connecting rod bearings to seat perfectly

🚛 Compatibility with Main Engines

• Cummins: ISX, ISX15, X15, N14, ISM, ISL, M11 and more
• Caterpillar: C15, C13, C12, 3406E, C7 and current series

Proper Storage:

• Store in a dry place, protected from moisture.
• Keep in its original packaging until the time of installation
• Avoid direct contact with the floor; use pallets or shelves.
• Protect from corrosion by applying protective oil if stored for extended periods.
• Do not store in contact with corrosive chemicals
• Keep away from areas with high humidity
• Store horizontally on suitable supports

Safe Handling:

• Crankshafts are extremely heavy; use appropriate lifting equipment
• Never attempt to lift a crankshaft manually without assistance
• Use slings and workshop cranes to move crankshafts
• Handle with extreme care to avoid impacts that may cause micro-cracks.
• Do not drop or subject to impacts
• Wear work gloves when handling
• Protect the stumps from bumps and scratches
• Check that the packaging is intact before opening

Critical Surface Protection:

• The main and connecting rod journals must be kept free of scratches.
• Do not use the stumps as gripping points
• Protect polished surfaces with clean paper or cloth
• Prevent dirt from entering the lubrication channels
• Keep the threads at the ends clean and protected.

Before Installation:

• Inspect the crankshaft for shipping damage
• Verify that the part number exactly matches your engine
• Measure the trunnions with a micrometer to verify tolerances
• Clean all lubrication channels with compressed air
• Make sure you have all the necessary components for installation
• Verify that the engine block is in optimal condition.

⚠️ Warning: Crankshafts are extremely heavy and critical components. Always use appropriate lifting equipment and follow safety procedures. A damaged crankshaft can cause catastrophic engine failure.

🔧 Why Invest in OEM Brand Crankshafts

Installing a crankshaft of dubious origin is the most expensive mistake a truck owner can make. A crankshaft from a reputable brand like FP Diesel or Cummins ensures that the journal dimensions are precise, allowing the main and connecting rod bearings to seat perfectly. This is the heaviest and most expensive part of the engine, and it must be flawless.

Benefits of using premium brand crankshafts:

• Total elimination of vibrations thanks to precision dynamic balancing
• Resistance to millions of combustion cycles without material fatigue
• Lubrication channels optimized for constant oil flow
• Perfect compatibility with OEM main and connecting rod bearings
• Guarantee that every horsepower reaches the transmission with total efficiency

Required Components When Replacing the Crankshaft:

• New Damper (Vibration Damper): Protects the crankshaft from destructive torsional vibrations
• High-quality seals: Prevent oil leaks at the crankshaft ends
• New main and connecting rod bearings: Ensure perfect tolerances and optimal lubrication
• New screws: The bench screws are single-use and must be replaced.
• Premium engine oil: Use oil that meets the manufacturer's exact specifications.

Installation Procedure (Summary):

• Thoroughly clean the engine block and mounting surfaces
• Inspect the block for cracks or damage
• Install the new main bearings in the block
• Lubricate the crankshaft journals with engine oil
• Install the crankshaft carefully using lifting equipment
• Install the main bearing caps with new metal parts.
• Tighten the main bearing bolts according to the manufacturer's specifications and sequence.
• Check the crankshaft end play
• Check the radial play of the metals with Plastigage
• Install the pistons and connecting rods with new bearings
• Install the damper and flywheel with new bolts
• Install the front and rear seals

Critical Torque Specifications:

• Bench screws require a specific torque and tightening angle.
• Follow the manufacturer's specifications exactly.
• Use a calibrated torque wrench and angle gauge
• Tighten in the correct sequence (usually from the center outwards)
• Never reuse bench vises - they are for single use only

Post-Installation Checks:

• Verify that the crankshaft rotates freely by hand.
• Confirm axial play is within specifications
• Check the main and connecting rod bearing clearance.
• Inspect for oil leaks at the seals
• Check the damper and flywheel alignment

Pro Tips:

• This is a repair that requires professional expertise.
• Use only specialized and calibrated tools
• Document all measurements and specifications
• Follow the manufacturer's service manual to the letter
• Consider balancing the entire assembly (crankshaft, damper, flywheel)
• Save all rebuild records for the engine history
