22.3
thrust
The 3.OL engine uses a
bearing (shim) located on
the number 3 journal
Upper and lower bearings
(for center)
22.6 Main bearing designations for the 2.OL and 2.4L engines -
the thrust bearing is installed in the number three cap and saddle
13 Install the number one (top) ring in the same manner. Make sure the
mark is facing up. Be careful not to confuse the number one and number
two rings.
14 Repeat the procedure for the remaining pistons and rings.
22 Crankshaft - installation and main bearing
oil clearance check
Refer to illustrations 22.3, 22.6, 22. I!, 22.13 and 22.15
I Crankshaft installation is the first step in engine reassembly. It’s as-
sumed at this point that the engine block and crankshaft have been
cleaned, inspected and repaired or reconditioned.
2 Position the engine with the bottom facing up.
3 Remove the main bearing cap bolts and lift out the caps. Lay them out
in the proper order to ensure correct installation
(see illustration).
4 If they’re still in place, remove the original bearing inserts from the
block and the main bearing caps. Wipe the bearing surfaces of the block
and caps with aclean, lint-free cloth. They must be kept spotlessly clean.
Main bearing oil clearance check
Note:
Don’t touch the faces of the new bearing inserts with your fingers.
Oil and acids from your skin can etch the bearings.
22.11 Lay the Plastigage strips (arrow) on the main bearing
journals, parallel to the crankshaft centerline -
5 Clean the back sides of the new main bearing inserts and lay one in
each main bearing saddle in the block. If one of the bearing inserts from
each set has a large groove in it, make sure the grooved insert is installed
in the block. Lay the other bearing from each set in the corresponding main
bearing cap. Make sure the tab on the bearing insert fits into the recess fn
the block or cap.
Caution:
Theoilholesin the blockmustlineup with theoil
holes in the bearing inserts. Do not hammer the bearing into place and
donlnick orgouge the bearing faces. No lubrication should be usedat this
time.
6 The flanged thrust bearing must be installed in the number two cap
and saddle (counting from the front of the engine) on 2.6L engines. On the
2.OL, 2.4L
(see illustration)
and 3.OL engines the thrust bearing must be
installed in the number three (center) cap and saddle.
7 Clean the faces ofthe bearings in the block and the crankshaft mahi
bearing journals with a clean, lint-free cloth.
8 Check or clean the oil holes in the crankshaft, as any dirt here can g0
only one way - straight through the new bearings.
9 Once you’re certain the crankshaft is clean, carefully lay it in position
in the main bearings.
