Remove all main bearing caps except the No. 1 and 7 main bearing cap for 6 cylinder engine. The 4 cylinder
engine is depicted in the illustration.
Use a pin to roll out the upper bearings from between the crankshaft and cylinder block.
To make a pin, grind a 6 mm capscrew to the dimensions shown.
Install the pin into the lubricating oil hole in the crankshaft.
Rotate the crankshaft so the pin pushes against the end of the main bearing opposite the tank. Remove the main
bearing.
Follow this procedure to remove the other main bearings.
Inspect all main bearing caps and main bearing crankshaft journals.
Determine the size of the main bearing removed and obtain the same size for installation.
Refer to Base Engine Component Specifications for the dimensions of the standard and undersize main bearing
journals.
Caution: Do not lubricate the side that is against the cylinder block.
Apply a coat of Lubriplate 105® to the new upper main bearings.
Position the new main bearing on the crankshaft and install as far as possible by hand.
Using the pin, finish pushing the main bearing in slowly being sure it is aligned with the cylinder block. Make sure
the tang on the main bearing sets into the notch.
Caution; Make sure the pin does not slide under the bearing.
Install the lower main bearings into the main bearing caps. Apply a coat of Lubriplate 105® to the main bearings.
Caution: Make sure the caps are correctly installed with the number towards the oil cooler side of the engine.
Install a main bearing cap after each upper main bearing is installed to keep the main bearing in place while the
other uppers are installed.
Tighten the capscrews to 50 N*m [37 ft-lb].
Do not tighten to the final torque value at this time.
Use the same procedure to remove and install rear main bean ng cap, No. 5 or No. 7.
