Subject:Information on a New Engine Preluber Tool

Models:1990-2002 All Cars and Light Duty Trucks



A new engine Preluber tool has been developed as an essential tool. This tool will be automatically shipped to all tier one and tier two dealerships. The new tool is known as J-45299 ENGINE PRELUBER.


Object Number: 863255  Size: SH

The J-45299 ENGINE PRELUBER consists of a two gallon container, hand pump, flexible hose, adapter set and a two sided laminated instruction sheet. The engine preluber will inject clean engine oil into the engine oiling system. Following the instructions included with the tool will allow the main bearings, connecting rod bearings and the oil pump to be properly lubed. When prelubing the engine with more than the minimum recommended amount of oil, the camshaft bearings and other valve train components may also be lubricated.

Notice:  Neglecting to prelube or improperly prelubing a new, remanufactured or serviced engine prior to the initial start-up may lead to premature bearing failure in the engine.

This tool should be used when installing a new engine, remanufactured engine or an overhauled engine. This tool and procedure should also be used when the crankshaft or connecting rods have been removed from the engine for any reason.

Any dealers or other interested parties can purchase this tool directly from Kent Moore by calling 1-800-345-2233.
