1022-3 RUN-IN-INSTRUCTIONS Engine Lubrication When the engine rebuild is complete, fill the engine crankcase with Case HDM oil and install new engine oil filters. NOTE: If Case HDM oil is not used, use only a Series 3 DS or CD Service Classif~cation oil that has the proper viscosity rating for prevailing air temperature. Refer to vehicle Operators Manual. After the first 20 hours of operation, change the engine oil while the engine is hot and replace the the engine oil filter Is. DO NOT DRAIN OIL UNTIL THE ENGINE HAS BEEN OPERA TED 20 HOURS. Change the engine oil and filterls at the recommended intervals thereafter as outlined in the Operator's Manual. Break-In Procedure for Rebuilt Engines (With a Dynamometer) The following procedure must be implemented when using a PTO dynamometer to break-in the engine. The dynamometer will insure control of the engine load at each speed and will eliminate over stressing new parts during break-in. During the break-in, continually check the oil pressure, coolant level, and coolant temperature. STEP 1 TIME ENGINE SPEED "10 Minutes 1000 RPM DYNAMOMETER SCALE LOAD*' None 2 3 4 5 6 "10 Minutes 1800 RPM 20 Minutes 1800 RPM 20 Minutes 1800 RPM "*'30 Minutes 100 RPM below rated speed Retorque the cylinder head bolts using the this service manual. None 1/3 1/2 3/4 procedure described in Section 2015 of *'Based upon normal dynamometer scale load at rated speed for the particular vehicle model. Reduce this scale load as indicated. "The most ideal break-in procedure would be to constantly vary the throttle between 750 to 1000 RPM for the first 10 minutes and from 1000 RPM to 1800 RPM for the next 10 minutes. The purpose of this changing RPM is to vary the lubrication and coolant flow. "*'30 minutes at 3/4 load is a minimum amount of time the engine should be run. It is recommended that whenever possible the engine (especially turbocharged diesels) should be run for four (4) hours or more at the above speed and load before checking the full engine horsepower or before using the engine for heavy field work.

1022-4 Run-I n Procedure (Agricultural Tractors) For the first 8 hours of field operation stay one gear lower than normal. For the next 12 hours DO NOT "lug" the engine. Prevent "lugging" by shifting to a lower gear. The engine must not be "lugged" below its Rated Engine RPM during the early hours of life. Run-In Procedure (Construction Equipment) For the first 8 hours, operate the engine at full throttle maintaining a normal load. DO NOT baby the engine, but avoid prolonged converter or hydraulic stall. Engine must not be "lugged" below its Rated Engine RPM (Do not exceed 10 seconds of stall). Run-In Procedure (Power Units) For the first 1/2 hour, operate engine at 2/3 rated RPM with a light load or no load. For the next (1) hour, run engine at 80 to 90% load at rated RPM (but not over 2000 RPM). Then full load and rated RPM as required in application.
