How to install the Main Bearings and Crankshaft on Lincoln Navigator?

On VS engines, the bolts used are what is commonly known as "torque-to-yield" bolts and cannot be used again once removed; these include the main bearing cap bolts and side bolts, but the conventional bolts such as the main cap side bolts and jack screws are reusable. Starting the assembly of the engine, the crankshaft and engine block should be clean and checked for any daamges and the position of the engine should have its bottom lacing up. You should now turn the engine until the main bearing cap is visible, and then unbolt and lift off the cap, making a point of placing the caps in an order that you will remember easily. Bearing inserts that fitted initially need to be withdrawn and the bearing surfaces ought to be cleaned. New main bearing inserts are to be fitted and oil holes in the bearings ought not to be damaged while fitting. The position of flanged thrust bearing must be correct depending on the type of the engine. Depose with witness the crankshaft and the bearing faces then put the crankshaft into its rightful position. It is recommended to check the oil clearance of the main bearing with the help of Plastigage without shifting the caps and without damaging the Plastigage. If clearance is measured with error, ensure that no obstructions were in the way at the time of measurement. Customer states after checking, wipe off Plastigage residue. For the final position of crankshaft, use oil to affected areas for the bearings, fit caps followed by tightening the bolts in the right manner. For the tightening of the V6 engines, put RTV sealant on the threaded area. On V8 engines it is important to replace the jack screws in case they were removed, the thrust washers should be greased and the main caps have to be properly fitted. Loosen new main cap bolts due to gasket removal, then apply specified torque to re-seat crankshaft. Upon that check the crankshaft end float and rotate the crankshaft and look for binding and finally fit the rear main oil seal.

Lincoln Navigator Crankshaft

The Lincoln Navigator Crankshaft converts straight-line thrust from the pistons into smooth rotary power. This rotary power ultimately turns the transmission, axles, and wheels. The Crankshaft is located in the block of the engine, on precision main journals, and the connecting rods grip offset throws that turn a throw with little friction. Both early and current Navigator models use the same basic layout. The difference comes from power levels which dictate material choice. For example, lower output Lincoln engines are made from cast iron while forged steel is applied for higher horsepower versions. Finally, heavy loading requires the Crankshaft to remain rigid so nothing compromises performance. Regular service is vital because oil carries off heat and dirt. If neglected, grit will score the journals, widen the clearances, and cause engine knock which indicates a hurt Crankshaft. Although designed to outlast the truck, a damaged Crankshaft requires complete engine removal, numbering caps, replacing bearings, properly torquing everything, and careful alignment so the rebuilt Lincoln power plant turns freely. The Navigator has labeled the steps as difficult. So take your time on the reinstall because each Navigator main cap must return to its original location to protect oil clearances in the Lincoln engine.

We provide a wide range of Lincoln Navigator Crankshaft at the optimal prices. If you need Lincoln Navigator Crankshaft, you can shop with confidence on our website. All our OEM parts come with a manufacturer's warranty and are delivered to your doorstep with a fast delivery service.
