(d) Check the piston pin fit at room temperature.
Coat the piston pin with engine oil and push it into the con-
necting rod with your thumb.
15. INSPECT CONNECTING ROD BOLTS
Using vernier calipers, measure the minimum diameter of the
compressed bolt at the measuring point.
Standard diameter: 8.1 - 8.3 mm (0.319 - 0.327 in.)
Minimum diameter: 8.0 mm (0.315 in.)
If the diameter is less than minimum, replace the connecting rod
bolt.

16. INSPECT CRANKSHAFT FOR RUNOUT
(a) Place the crankshaft on V-blocks.
(b) Using a dial indicator, measure the circle runout at the
center journal.
Maximum circle runout: 0.06 mm (0.0024 in.)
If the circle runout is greater than maximum, replace the crank-
shaft.

17. INSPECT MAIN JOURNALS AND CRANK PINS
(a) Using a micrometer, measure the diameter of each main
journal and crank pin.
Diameter:
Item | STD⬜⬜ mm (in.) | U/S 0.25⬜ mm (in.)
Main journal | 61.984 - 62.000 (2.4403 - 2.4409) | 61.745 - 61.755 (2.4309 - 2.4313)
Crank pin | 51.982 - 52.000 (2.0465 - 2.0472) | 51.745 - 51.755 (0.0372 - 2.0376)
If the diameter is not as specified, check the oil clearance. (See
page EM-71 )
(b) Check each main journal and crank pin for taper and out-
of-round as shown.
Maximum taper and out-of round:
0.02 mm (0.0008 in.)
If the taper or out-of-round is greater than maximum, grind or
replace the crankshaft.
