#1 Clearance

1. Measure the O.D. of the crankshaft journal with an

outside micrometer.

2. Measure the I.D. of crankshaft 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 bearing, install an undersize bearing by referring
to the table below.

2.3.4.e Replacing Crankshaft Bearing #1

(A) When Removing

1. Press out the crankshaft bearing #1 (2) using a crank-

shaft bearing (1) replacing tool.

(B) When Installing

1. Clean a new crankshaft bearing #1 (2) and crankshaft

journal bore, and apply engine oil to both.

2. Using the crankshaft bearing (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 bushing so that the oil hole
in the bushing aligns with the oil port in the con-
necting rod.
