Re-Manufactured Engine Break-In Procedures

Break-In Instructions:

Do not let the engine idle for prolonged periods of time. The idle time should never exceed 5 minutes during the first 3 hours of operation.
Re-torque the cylinder head bolts per OEM service manual specs after two hours of run time.
Operate the engine in the normal RPM range at approximately 75% load for the first three hours.
Limit periods of full load or full speed operation during the break-in period to short intervals of no more than 2 to 3 minutes at a time.
Before engine shut down, be sure to allow the engine operating temperature to cool down and stabilize by operating at no load for 3 to 4 minutes.
Vary the operating speed for the first 20 to 25 hours of operation, avoid running the new engine at a constant RPM.

Planned Maintenance:

Refer to and follow all OEM service manual requirements for all servicing intervals. Including: Head torque, valve adjustments, fluid changes, and belt checks. Always feel free to call us and speak to an engine technician if you are unsure of anything.


Check the exhaust system to see if the previous engine burned oil. Verify that the muffler isn't starting to plug up. Also, when running the new engine, make sure it burns out any and all excess oil left by the previous engine.
When installing all accessories, be sure to check for proper bolt lengths. Sometimes bolt holes intersect with moving internal components.
This engine is equipped with two heat indicators; the engine warranty will be void if any of these indicators are melted, removed, or tampered with.
