Information:
Start By:a. remove oil panb. remove oil pump 1. Remove bolts (1) and bearing cap (2). Remove the bearing half from the cap.
If the crankshaft is turned in the wrong direction, the tab of the bearing will be pushed between the crankshaft and cylinder block. This can cause damage to either or both the crankshaft and the block.
2. Remove the upper half of the main bearings as follows:a. Turn the crankshaft until tool (A) can be installed in the crankshaft journal oil passage. Install tool (A).b. Turn the crankshaft in the direction which will push the upper main bearing out, tab end first.c. Check the condition of the bearings. (See Guideline For Reusable Parts, Main And Connecting Rod Bearings, FORM No. SEBF8009 and SEBD0531). Both the center and two end main journals have no oil hole. To remove these bearings, put a thin piece of soft material, (that will not damage the crankshaft journal), against the end of the bearing opposite the tab. Hit the bearing with the soft material until the tab of the bearing is free from the groove in the block. The following steps are for the installation of the crankshaft main bearings. Put clean engine oil on the main bearings for the assembly. Also, be sure the tabs on the back side of the main bearings fit in the grooves of the main bearing caps and cylinder block.3. Clean the surfaces in the cylinder block for the main bearings. Use tool (A), and install new upper halves of main bearing (bearings with the oil hole) in the cylinder block. Do not put oil on the back of the bearing.4. Clean the surface of the main bearing caps for the main bearings. Install the new lower halves of the main bearings in the main caps. Do not put oil on the back of the bearing.
Install the main bearing caps with the sequence number to the right, 1 through 7, front to rear.
5. Put main bearing caps (2) in position on the cylinder block. Put engine oil on the bolt threads and the contact surfaces of the bolt heads, and install the bolts. Tighten the bolts on the side where the main bearing tabs are located to a torque of 54 7 N m (40 5 lb.ft.). Tighten the bolts on the opposite side to a torque of 54 7 N m (40 5 lb.ft.).6. Put a mark on each bolt head and the bearing caps. Turn the bolts that are opposite the main bearing tabs an additional 90° 5° turn. Then turn the bolts on the side where the main bearing tabs are located an additional 90° 5° turn. 8. Check the end play of the crankshaft with a dial indicator and magnetic base. The end play must be 0.07 to 0.24 mm (.003 to .009 in.). The end play is controlled by the thrust bearings, which are part of main bearing No. six.End By:a. install oil pumpb. install oil pan
