Suggested Engine Installation Procedures and Instructions:
GASOLINE ENGINES
Suggested Engine Installation Procedures and Instructions:
Installing By Mechanic Or Technician Our diesel engine has been carefully remanufactured to precision standards, and will perform properly IF certain steps are taken by the person making the installation.

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 ASE, or an ADS certificate or the equivalent before you accept the RESPONSIBILITY of properly installing an engine.

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

CAUTION, 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, push rods, rocker arms, oil pump screen with new screen, motor mounts, oil filter, air filters, water pump, thermostats, crankcase ventilation system, clean lines (Note: A plugged line or faulty assembly may cause excessive oil consumption), remanufactured or new fuel system components, new or remanufactured Oil-Cooler when applicable, remanufactured, turbocharger, and the supercharger intercooler.

Insure the EGR valve is operating to O.E.M specifications. (if applicable)

Follow the manufacturer's installation procedures; especially proper torque values. Inspect the rocker cover baffle for possible restrictions.

Contamination is an engine's worst enemy. We recommend that you thoroughly clean the parts that will be attached to the rebuilt/remanufactured engine.

Any and all parts not included with a remanufactured engine or engine component should be cleaned properly before installing on a new remanufactured 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 rebuilder.

CAUTION, 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, push rods, rocker arms, oil pump screen with new screen, 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 blowby), carburetor (may be rebuilt) and make sure the EGR valve is operating to OEM specifications.

Any and all parts not included with a remanufactured engine or engine component should be cleaned properly before installing on a new remanufactured engine.

Rubber Goods Don't overlook small parts such as belts, hoses (those that carry liquids and air) and motor mounts which become weak and worn with age. We suggest that these items be replaced at the time of engine replacement.

Be sure to service and inspect accessories such as alternator, starter, water pump, air compressor, fuel system, EGR valves and all sensors to avoid premature engine failure.
Flywheel
  • Install bolts with sealer or replace as required.
  • On engines that use a 1-piece full circle rear main seal and flangeless flywheel mounting system, over torque of the fly wheel bolts may distort the rear seal area and cause an oil leak.
  • Verify clearance between flywheel and seal housing.

Engine Start-Up
  • Do not under any circumstances use starting fluid.
  • Engine should start, excessive cranking may be present.

  • Pull off lines, if valve is defective, oil may be present.
  • Replace if above condition is observed, as it may allow transmission fluid to enter engine through vacuum system and prevent proper ring seal.
Exhaust Manifold Pressure & System
  • Replace oxygen sensor with a low pressure gauge.
  • Run engine at 2500 RPM for 1 minute.
  • High pressure reading should be less than 2.5 pounds.

  • Inspect exhaust manifold for internal and external cracks, especially on marine applications.
Engine Analysis OIL PRESSURE
  • Observe oil pressure reading immediately after starting the engine. If there is no oil pressure within 10-15 seconds, stop engine and check lubricating oiling system. Once recommended engine break-in period is concluded, oil sampling should be done to verify no premature or abnormal component wear occurrence.
Run-In
  • Run engine at part throttle and at no-load until it reaches operating temperature prior to applying any load.
Inspection
  • With engine running at operating temperature, check for coolant, fuel or lubricating oil leaks.
Cooling system
  • Verify that cooling system has reached operating temperature and circulated effectively and that the level is correct.
  • Avoid unnecessary idling periods, engine coolant temperature will fall below normal operating temperature range. Once normal cooling system operation has been verified appropriate coolant conditioner should be introduced to avoid cavitation and electrolysis.
Turbocharger (if applicable)
  • Visual inspection of leaks and possible vibrations should be observed. If there is any unusual noise STOP engine immediately.
  • Make an engine analysis data sheet (either a diagnostic printout or handwritten form) showing the status of the engine and the Engine Support System before installation, after installation and at the 500 mile checkup.
  • Check engine or service engine soon lights (computer-control problems).
  • Check for any trouble codes, this may be a clue to why the engine previously failed.
  • Check for correct vacuum hose routing and for vacuum leaks.
  • Replace distributor, wiring, coil, and spark plugs to avoid poor performance. On V-8's, check plug routing.
