Why Choose This Reman 3406C Engine GP?

1. Cost Effective: Approximately 30-50% less than a new engine, while delivering like-new performance.

2. Core Exchange: Most suppliers offer core credit for your old 3406C engine assembly.

3. Dyno Tested: Each reman engine is hot-tested for oil pressure, compression, fuel system performance, and leak-free operation.

4. OEM-Spec Components: New pistons, rings, bearings, gaskets, and seals meet or exceed Caterpillar specifications.

5. Industry-Standard Warranty: Typically 1-2 years / unlimited hours (verify with supplier).

Signs You Need a Complete Engine GP Replacement

• Major engine failure (cracked block, spun bearings, seized crankshaft)

• Excessive oil consumption with blue smoke

• Loss of power across all RPM ranges

• High blow-by from crankcase breather

• Low compression on multiple cylinders

• Repeated repairs exceeding the value of a reman engine

• Preventative replacement at high hours (15,000-20,000+ hours)

Installation Recommendations

• Disconnect and label all electrical, fuel, coolant, and hydraulic connections.

• Remove the old engine GP and transfer reusable accessories.

• Inspect and replace engine mounts – they are typically worn.

• Align bellhousing and torque flywheel-to-converter bolts to specification (typically 120-150 Nm for 3406C).

• Install new starter and alternator (recommended).

• Refill with Caterpillar-approved engine oil (15W-40 diesel oil, API CK-4) and coolant (ELC or similar).

• Prime the fuel system before attempting to start.

• Perform initial startup and break-in: vary RPM for first hour, check for leaks, verify oil pressure (30-60 PSI at operating RPM).

• Retorque head bolts and adjust valve lash after first 100 hours (consult service manual).
