BREAK-IN PROCEDURES FOR REMANUFACTURED ENGINES
This engine has been rebuilt to give long, satisfactory service. Protect your investment by following these instructions before installing or starting the engine.
Dear installing Mechanic/Technician; This engine has been carefully remanufactured to precision standards, and will perform properly IF the person making the installation takes certain steps. An engine is a complex component that requires the highest degree of technical knowledge to install. It is recommended that you, the installer, have an A.S.E. certificate or the equivalent before you accept the RESPONSIBILTY of properly installing an engine.

When a properly remanufactured engine fails to give satisfactory service, it can be due to detonation, pre-ignition or “lugging”, overheating or excessively rich air-fuel ratio, under lubrication, dirt, coolant seepage, ineffective air filtering. The above-mentioned reasons for failure are the responsibility, and under the control, of the installing mechanic/technician not the engine remanufacture.

Please Note: These recommended installation procedures and instructions are a partial list intended only as a guide. If you are not qualified to undertake this installation, do not attempt it, as you may be liable for resulting engine failure.

Replacing all of the following with new or rebuilt/remanufactured units is recommended: valve lifters, oil pump, pushrods, rocker arms, spark plugs, points (if applicable), condenser, motor mounts, oil filter, air filters, water pump, thermostats, PCV valve & grommets and clean lines (Note: a plugged line or faulty valve may cause excessive oil consumption and blow by), carburetor (may be rebuilt) and make sure the EGR valve is operating to OEM specifications. Follow the manufacturer’s installation procedures making special note of proper torque values. Also, inspect the rocker cover baffle for possible restrictions.

Contamination is an engine’s worst enemy. We strongly recommend that you thoroughly clean parts that will be attached to the rebuilt/remanufactured engine. Upon initial start up the engine, the RPM must be raised between 1500-2000 RPM for 10-20 minutes for proper camshaft break-in. Do not let the engine remain idle for long periods of time. Make a test run at 30 miles per hour and accelerate at full throttle to 50 miles per hour. Repeat the acceleration cycle from 30-50 miles per hour at least 10 times. If traffic conditions will not permit this procedure, accelerate the engine rapidly several times through the intermediate gears during the check run. The object is to apply a load to the engine for short periods of time and in rapid succession soon after engine warm up. This action thrusts the piston rings against the cylinder wall with increased pressure and results in accelerated ring seating.

Passenger Car and Light Truck

Drive vehicle normally but avoid sustained high speed during the first 100 miles. **First oil and filter change should be completed after 500 miles of driving and before 1000 miles has been reached. **

SUGGESTED PRECAUTIONS FOR REMANUFACRTURED ENGINES

You the customer and we the remanufactures have a mutual interest in this engine. We both want it to perform properly and give long, satisfactory service. This engine has been carefully remanufactured to precision standards, and will perform if the mechanic making the installation takes certain steps. Following is a list of causes for a remanufactured engine to fail early in service, and suggested procedures to prevent failure. When a properly remanufactured engine fails to give satisfactory service, it is usually due to: burnt pistons, damaged cylinder heads caused by detonation, pre-ignition or “lugging.” Piston scuffing or seizing is usually caused by overheating or excess fuel, bearing and crankshaft wear caused by under-lubrication, dirt or coolant seepage, excessive piston and cylinder wear caused by dirt, ineffective air filtering, excessively rich or lean air-fuel ratio.

We recommend these precautions as a guide:

LUBRICANT RECOMMENDATIONS FOR “BREAKING-IN“ REMANUFACTURED ENGINES

Follow the recommendations of the engine manufacturer for proper viscosity and type of oil to be used during and after the “break-in” period. It is important to use heavy-duty detergent oil, which contain EP (extreme pressure) additive right from the start. Special “break-in” oils should not be used unless specified by the manufacturer. Older engines without oil filters may require special considerations, such as the use of non-detergent oils unless otherwise specified by the manufacturer.

Consult the owner’s or service manual for the latest manufacturer’s recommendation on oil selection.

Be sure to prime the oil pump, oil lines and fill the oil filters with oil using an auxiliary pump, operating the internal oil pump with a hand drill or an external pressure tank connected to the oil pressure gauge or sending unit fitting before starting the engine. It is desirable to fill the crankcase in this manner. If using an air pressure tank be sure it does not run out of oil and blow air through the lines. Proper valve lash or clearance must also be set to proper specification Proper air-fuel ratio is vital in today’s engines. Be sure the carburetor or fuel injection system has been remanufactured to manufacturer’s specifications. Manifold and cylinder head surfaces should be checked and in good condition (resurface if necessary). Be sure the cylinder heads and manifolds are torque and re-torqued in proper sequence if required. Air seepage can cause lean air-fuel ratio, which causes detonation or improper ring seal causing loss of oil. Check fuel pump for proper pressure. Vacuum lines must be properly routed and connected to the appropriate fittings to ensure operation of emission control devices and related engine controls. Clean the intake manifold to remove deposits from the various passages. Important: replace filter elements. Thoroughly check engine accessories, which are to be reused. Clean them internally and externally before installing. Check the exhaust thermostat control (commonly called the heat riser) to be certain it is free and operating properly. Check the exhaust gas re-circulation valve (EGR valve) for proper operation. Ignition or diesel fuel injection systems should be properly serviced or calibrated, and engine timing set to proper specifications. Be sure to use spark plugs of the correct heat range and gap as specified by the engine manufacturer. Check electronic sensors and sending units for proper operation. . Rebuild or replace the radiator and hose lines to ensure they are free from deposits so that the cooling system can function properly. Restrictions can cause overheating. The coolant used should be compatible with aluminum engine components and blended to a mixture of no more than 60% antifreeze and 40% water. We recommend that a good sealer with rust inhibitors be added to the cooling system. This will tend to prevent rust and scale deposits and guard against coolant seepage. Thermostats should be checked or replaced with one of the correct temperature. Use the proper pressure cap as specified by the engine manufacture, and make sure it is properly sealed.
