Normal Wear: Remanufactured engine products, like all mechanical devices, need periodic parts service and replacement to perform correctly. Our warranty would not apply if damage to the product has occurred because of misuse, lack of routine maintenance, shipping, handling, warehousing or improper installation. Similarly, warranty is void if the serial number of the product has been removed or the product has been altered or modified with aftermarket performance enhancing parts.


The life of a mechanical device depends upon the conditions under which it operates, and the care it receives. Wear, when caused by dirt, dust, spark plug cleaning grit or other abrasive material that has entered the engine because of improper maintenance, is not covered by warranty.

Our warranty will not extend to cover repairs if:

  1. Problems caused by parts that are not our original (remanufacturer) parts.
  2. Damage as a result of Overheating, Lack of Lubrication, Fuel Wash or Contamination.
  3. Damage resulting from Pre-Ignition or Detonation - Including but not limited to melted or broken piston, broken piston rings, damaged cylinder heads, leaking head gaskets, etc.

  6. Any product used for competition, racing or related purposes.
  7. Any product to which a device or accessory not conforming to original manufacturer’s specifications has been installed.
  8. Damage as a result of electrolysis, including but not limited to, deterioration of engine components as a result of excessive electrical current.
  9. Improperly maintained coolant, and/or any product on which periodic maintenance services required by the original manufacturer have not been performed.
  10. Crankshaft Thrust Surface worn due to excessive forward pressure placed on the rear of the crankshaft.

  16. Engine or equipment parts broken by excessive vibration caused by a loose engine mounting, improper attachment of equipment to engine crankshaft or other abuse in operation.
  17. Lack of routine tune-up or adjustment of the engine.
  18. Engine or engine component failure, i.e., combustion chamber, valves, valve seats, valve guides or burned starter motor windings, caused by the use of alternate fuels such as, liquefied petroleum, natural gas, altered gasoline, etc.

No warranty shall apply to products installed on any Recreational Vehicles over 11,000 pounds Gross Vehicle Weight which includes most Class A, Class B and Class C Motor Homes and Bus conversions. Additionally, please be aware that the only engines designed expressly for large motor homes should never be used in such an application.

Products used in competitive racing or on commercial or rental race tracks are not warranted.
