12. Remove the connecting rod caps after setting the
crank pin at bottom dead center (BDC) for each
cylinder. Remove the piston/connecting rod
assembly by pushing on the connecting rod. Take
care not to damage the crank pin or cylinder with
the connecting rod.
13. Remove the bearing from the cap. Keep all caps/
bearings in order.
14. Remove the upper bearing halves from the
connecting rods, and set them aside with their
respective caps.
15. After removing a piston/connecting rod assembly,
reinstall the cap on the rod.
16. To avoid mix-up during reassembly, mark each
piston/connecting rod assembly with its cylinder
number.
17. Unscrew the bearing cap bolts and bearing cap
side bolts in sequence 1/3 turn at a time; repeat the
sequence until all bolts are loosened.

18. Remove the bearing cap bolts (A) and bearing cap
side bolts (B), then remove the bearing cap (C).
19. Lift the crankshaft (A) out of the engine block, being
careful not to damage the journals.
20. Reinstall the main caps and bearings on the engine
block in the proper order.
1. Remove the crankshaft from the engine block
(see page 7-12).
2. Clean the crankshaft oil passages with pipe
cleaners or a suitable brush.
3. Check the keyway and threads.
4. Measure out-of -round at the middle of each rod
and main journal in two places. The difference
between measurements on each journal must not
be more than the service limit.
5. Measure taper at the edges of each rod and main
journal. The difference between measurements on
each journal must not be more than the service
limit.

6. Place the engine block on the surface plate.
7. Clean and install the bearings on the No. 1 and
No. 4 journal of the engine block.
8. Lower the crankshaft into the engine block.
9. Measure the runout on all of the main journals.

The difference between measurements on each
journal must not be more than the service limit.
1. Remove the piston from the engine block (see page
7-12).
2. Check the piston for distortion or cracks.
3. Measure the piston diameter at a point 16.0 mm
(0.63 in.) from the bottom of the skirt.

4. Measure wear and taper in direction X and Y at
three levels in each cylinder as shown. If
measurements in any cylinder are beyond the
oversize bore service limit, replace the engine block.
If the engine block has to be rebored, refer to step 7
after reboring.
5. Hone any scored or scratched cylinder bores.
(see page 7-17).
6. Check the top of the engine block for warpage.
Measure along the edges and across the center as
shown.
