SOURCE: i removed the number 3 main bearing cap and found

all the cars that I have worked on in the past have the thrust washer as part of the bearing shell which looks like a shell that has had both the sides folded up. not real sure about your motor but.
If it is like I said the shell comes as 2 halves, if you remove the bearing cap you should be able to push on one side of the bearing that does not have a little protruding piece that lock that half of the bearing from turning around.
If the surface of the crank that was rubbing on the block is rough and scored the crank will have to be replaced or machined depending on the damage that it has had done to it.
If you use it damaged you will ruin the bearing very quickly and have to start all over again

Torque for main bearings on a 2002 3.7 ltr. liberty?


the book is free to read? KJ
chapter 9s
(7) Before installing bolts, lubricate the threads
with clean engine oil, wipe off any excess oil.
(8) Install main bearing bedplate to engine block
bolts 11, 17 and 20 finger tight. Tighten these bolts
down together until the bedplate contacts the cylinder
block.
(9) To ensure correct thrust bearing alignment,
perform the following steps:
² Step 1: Rotate crankshaft until number 4 piston
is at TDC.
² Step 2: Move crankshaft rearward to limits of
travel.
² Step 3: Then, move crankshaft forward to limits
of travel.
² Step 4: Wedge an appropriate tool between the
rear of the cylinder block (NOT BED PLATE) and
the rear crankshaft counterweight. This will hold the
crankshaft in it's furthest forward position.
² Step 5: Install and tighten bolts (1-10) in
sequence shown in (Fig. 49) to 41 N·m (30 ft. lbs.).
² Step 6: Remove wedge tool used to hold crankshaft.
(10) Tighten bolts (1-10) again to 41 N·m (30 ft.
lbs.) PLUS 1/4 turn in sequence shown in (Fig. 49).
(11) Install main bearing bedplate to engine block
bolts (11-20), and torque each bolt to 28 N·m (20 ft.
lbs.) in sequence shown in (Fig. 49).
(12) After the main bearing bedplate is installed,
check the crankshaft turning torque. The turning
torque should not exceed 5.6 N·m (50 in. lbs.).

why not just read the chapter, here.

How many foot pounds of torque should I use to tighten the bolts that holds the crankshaft and the bolts of the pistonshaft on to the crankshaft?????


Ok, the main cap bolts (crankshaft) vary depending on 6 or 12 pt. head. 6 pt. head is just 14 ft. lbs. 12 pt head on the bolt requires it to be tightened in 4 stages, 16 ft. lbs., then 32 ft. lbs., then turn additional 90 degrees, then another additional 90 degrees. The connecting rod cap bolts (pistons) get 2 stages, 15 ft. lbs. then additional 90 degrees.

Replacing crankshaft pulley/balancer assy procedure. 1994 Merc Topaz 2.3 4cyl.


Crankshaft and Main Bearings REMOVAL & INSTALLATION NOTE: When draining coolant, keep in mind that cats and dogs are attracted by the ethylene glycol antifreeze, and are quite likely to drink any that is left in an uncovered container or in puddles on the ground. This will prove fatal in sufficient quantity. Always drain the coolant into a sealable container. Coolant should be reused unless it is contaminated or several years old. CAUTION
The EPA warns that prolonged contact with used engine oil may cause a number of skin disorders, including cancer! You should make every effort to minimize your exposure to used engine oil. Protective gloves should be worn when changing the oil. Wash your and and any other exposed skin areas as soon as possible after exposure to used engine oil. Soap and water, or waterless hand cleaner should be used. 2.3L Engine
  1. Disconnect the negative battery cable.
  2. Drain the cooling system and engine crankcase.
  3. Remove the engine from the vehicle.
  4. Remove the crankshaft front pulley, front cover, timing chain and sprockets, cylinder head, oil pan, oil pump and intermediate driveshaft.
  5. Remove the rear oil seal cover bolts and remove the cover.
  6. Remove the piston assemblies. NOTE: Mark the connecting rods and bearing caps so they can be installed in the proper cylinders.
  7. Remove the main bearing caps and bearing.
  8. Carefully lift the crankshaft out of the crankcase, so No. 3 thrust bearing surfaces are not damaged.
  9. Remove the main bearing inserts from the engine block and bearing caps. NOTE: For cleaning purposes, the oil gallery and coolant drain plugs can be removed. To install:
  10. Wash the cylinder block thoroughly to remove all foreign material and dry before assembling other components. Check to ensure all oil holes are fully open and clean. Check to ensure the bearing inserts and bearing bores are clean. Clean the mating surfaces of the crankcase and each main bearing cap.
  11. Install the main bearings in the cylinder block. Note that the center front bearing is a thrust bearing and the front upper bearing has a small "V'' notch on the parting line face.
  12. Lubricate the bearings with clean engine oil.
  13. Carefully lower the crankshaft into place. Be careful not to damage the bearing surfaces.
  14. Check the clearance of each main bearing as outlined in this section.
  15. After the bearing has been fitted, apply a light coat of engine oil to the journal and bearings. Install the bearing cap in their original locations . (refer to numbers on caps). The caps must be installed with the arrows pointing to ward the front of the engine. Oil the bolts and tighten to specifications. Repeat the procedure for the remaining bearings. NOTE: Turn the crankshaft to check for turning torque. The turning torque should not exceed 4.5 ft. lbs. (6 Nm).
  16. Install the pistons and connecting rod caps. Check clearance of each bearing, as out lined in this section.
  17. After the connecting rod bearings have been fitted, apply a light coat of engine oil to the journal and bearings.
  18. Turn the crankshaft throw to the bottom of its stroke. Pull the piston all the way down until the rod bearing seats on the crankshaft journal. NOTE: Guide the rod to prevent crankshaft journal and oil cooling jet damage.
  19. Install the connecting rod cap. Align the marks on the rods with the marks on the cap, and tighten the nut.
  20. After the piston and connecting rod assemblies have been installed, check the side clearance between the connecting rods on each connecting rod crankshaft journal.
  21. Install the rear crankshaft seal and cover. Tighten the bolts to 5–7 ft. lbs. (7–10 Nm).
  22. Installation of the remaining components is in the reverse order of removal.

Wiich is the torque specifications for crankshaft


Crankshaft endplay is controlled by the thrust bearing. Endplay tolerance is usually from 0.004"-0.006" for a crankshaft with a 2" to 2 3/4" main bearing diameter. If crankshaft endplay is too great, oversized thrust bearings or inserts may be available.

1. Check the connecting rod alignment If either the bend or the twist exceeds the specified limit,the connecting rod must be replaced. Bend per 100 mm (3.937 inch) Limit: 0.15 (0.0059) Twist per 100 mm (3.937 inch) Limit: 0.20 (0.0078)

2. Measure the connecting rod thrust clearance. Use a feeler gauge to measure the thrust clearance at the large end of the connecting rod If the clearance exceeds the specified limit, the connecting rod must be replaced. Standard: 0.16 mm - 0.35 mm (0.0063 inch - 0.0138 inch) Limit: 0.40 mm (0.0157 inch)

3. Measure the oil clearance between the connecting rod and the crankshaft.

    1. Remove the connecting rod cap nuts and the rod caps (12). Arrange the removed rod caps in the cylinder number order.
    2. Clean the rod bearings and the crankshaft pins.
      1. Carefully check the rod bearings. If even one bearing is found to be damaged or badly worn, the entire bearing assembly must be replaced as a set. Reinstall the bearings in their original positions. Apply plastigage to the crank pin.
      2. Reinstall the rod caps (12) to their original positions. Tighten the rod cap nuts. Torque: 54 Nm (40 ft. lbs.) Note: Do not allow the crankshaft to rotate.
      3. Remove the rod caps.
        1. Measure the width of the plastigage and determine the oil clearance. If the oil clearance exceeds the limit, replace the rod bearing as a set. Standard: 0.019 mm - 0.043 mm (0.0007 inch - 0.0017 inch) Limit: 0.08 mm (0.003 inch)
        2. Clean the plastigage from the bearings and the crankshaft pins.
