MAIN BEARINGS (Cont’d)

Installation

Check the bearing spread as listed [A].

Limit – 2.93 inch (74,5 mm)

Check to see if the bearing has enough tension, so that

finger pressure is needed to fit the bearing into the cap

[B].

Check the crankshaft journals before installing the main

bearings. (See Page 7–68.)

Make sure to position the bearing halves in their correct

locations [C].

Lubricate the new bearings. Install them by putting the

end without the tab into the block and rotating the

crankshaft until the tab is on its seat.

Install the other bearing half in the bearing cap. Lubricate

the bearing and install the cap on the engine block.

Lubricate the bolts, install them finger tight only.

Install the center main bearing and thrust washers [D].

The thrust washer must be installed so that their oil

grooves are turned to the rotating face of the crankshaft.

Repeat the procedure until all the main bearings and caps

are installed.
