Point 4: Journal bearing cap
[Disassemble]
• Before removing the journal bearing, measure the
crankshaft side gap. Measure it in either method
because there are the next two methods.
1)Install a dial gage on the cylinder block, and move a
crankshaft in front and back, and measure the side
gap as shown in the right figure.
2)Put a thickness gauge in the clearance between
thrust metal and crankshaft directly, and measure it.
Side gap standard
0.13 to 0.23
[Reassemble]
• If the side gap exceeds the standard, replace the
thrust metal with an oversized one.
• 0.25 mm Oversized thrust metal (0.25 DS)
Thrust metal assy code
119810-02940
[Disassemble]
• Remove the bearing caps, cap bearings, and thrust
metals. Place each thrust metal with identification of
the position and direction.
• Carefully install each thrust metal so that the grooved
one is positioned away from the cap.
[Reassemble]
• Do not confuse the upper and lower main bearing
metals. The upper main bearing metal (block side)
has an oil hole, and the lower one does not. The
"wheel and arrow" marks on the cap shall face the fly-
wheel.
