Test procedure List of checks The purpose of this procedure is to check a number of points before and after dynamometer testing. It is suited to engines with electronic control (TIER 2). Failure to carry out these tests may lead to an incorrect power reading. Always check the following points before starting a PTO power test. Reminder: Wait until the running-in period has elapsed (minimum 100 hours) before testing an engine on the dynamometer. This period is necessary to ensure that measurements are carried out under suitable conditions.
1. Visual checks Make sure that the supply and return lines are correctly fitted (not trapped or kinked on installation, etc.). Check that the engine serial nΒ° read with MΓ©tadiag is the same as the one indicated on the engine identification plate and if there are any error codes.

Check the level: Mark (K): Minimum level. Mark (J): Maximum level. A level above level (J) affects engine power and increases temperature. Example: Overfilling will significantly affect performance during high speed road operation.
