Engine Break In Procedure (Heat Cycles)

Reeve Industries LLC recommends the 10-10-10 method for engine break in. Our technician(s) will perform the first portion of the procedure. The second two portions are the responsibility of the client to perform. Failure to do so may result in reduced engine life.

The Purpose

The purpose of the engine break in procedure is to mate the new engine components properly and uniformly without extra stress. The heat cycling method reduces scoring and premature wear of the cylinder/piston and ensures increased engine performance and longevity when performed properly.

Before you begin

DO NOT EXCEED 3,500-4,000 RPM (about half throttle) in the break in procedure. Failure to comply may result in premature engine wear.

DO NOT IDLE THE ENGINE OR HOLD AT A CONSTANT RPM for the break in procedure. Failure to comply may result in uneven surface wear and reduce engine longevity.

The Procedure

1. Run the engine for 10 minutes while varying engine RPM (Revving the engine)

2. Let the engine cool completely for an additional 10 minutes (longer is better but not required)

Repeat steps 1 and 2 in the same order one additional time.

The Result

Properly executing the engine break-in procedure guarantees that the newly replaced or machined components fit together and seal effectively, without enduring unnecessary stress. This process enhances both engine performance and longevity, providing you with dependable power for countless hours ahead!
