#1 Clearance
1. Measure the O.D. of the crankshaft journal with an
outside micrometer.
2. Measure the I.D. of c rankshaft bearing #1 with an in-
side micrometer and calculate clearance.
3. If the clearance exceeds the allowable limit, replace
crankshaft bearing #1.
4. If the allowable limit is not attainable with a standard
size bear ing, install an undersize bearing by referring
to the table below.

2.3.4.e Replacing Crankshaft Bearing #1
(A) When Removing
1. Press out thecrankshaft bearing#1 (2) using acrank-
shaft bearing (1) replacing tool.
(B) When Installing
1. Cleana newcrankshaft bearing #1(2) and crankshaft
journal bore, and apply engine oil to both.
2. Using the c rankshaft bear ing (1) replacing tool, press
in the new bearing #1 (2) so that its seam (1) directs
toward the exhaust manifold side.
NOTE
Be sure to align the bus hing so that the oil hole
in the bushing aligns with the oil port in the con-
necting rod.
