REVALIDATION OF WARRANTY
FOR LONG-TERM STORAGE OF ENGINES
These procedures are intended to prevent oxidation and/or fatigue of internal engine and fuel injection equipment
components. If any engine has not been sold to the end user prior to nine (9) months after the manufactured build date
of the engine, the seller must revalidate each engine at this time, and every twelve (12) months afterwards for a maximum
of twenty-four (24) months for warranty coverage to be available, and provide written confirmation to WINCO inc that the
engine was revalidated. Warranty will be exhausted if the unit is still in the seller’s inventory after revalidation cycle.
1. Carefully inspect all external components for damage and/or corrosion
2. Rotate the engine approximately five (5) revolutions to prevent fatigue of internal engine components.
3. The engine must be protected from moisture intrusion and/or growth.
4. Circulate diesel fuel or fuel injection equipment calibration oil through the fuel injection equipment system
components, and ensure the fuel system remains sealed to prevent evaporation and/or contamination.
5. Fill the cooling system with coolant. If not installed in an application, the cooling system connections at the
thermostat housing and the water pump must remain dry and closed to limit environmental exposure and/or
corrosion.
6. The engine must be pre-oiled before start-up (see lubrication section for lubrication specifications. This involves
cranking the engine for one (1) minute at 10 second crank/10 second no crank intervals, while ensuring the engine
will not start, in order to circulate oil throughout the lubrication and turbo systems without damaging the starter
motor.
7. If the engine is installed in an application, “fogging” the engine is an acceptable method to protect the internal
engine components by operating the engine for 15minutes at 500-800 RPM, and nebulize the following amounts of
oil through the air intake system.
CAUTION: Exceeding the oil increments below may induce engine damage.
3-4 cylinder engines and per bank (8 cylinder engines)
60 grams
6
cylinder
engines
120
grams
12 cylinder engines (per bank)
80 grams
Service records indicating the requirements are performed must be maintained. Failure to comply with these storage
requirement procedures may revoke consignment privileges, and limit and/or void the applicable warranty on the engine.
