Disassembly and Reassembly

13. Use plastigauge to check the clearance
between the connecting rod bearings and the
corresponding crankshaft rod journal.
a. Place a piece of plastigauge on the
crankshaft rod journal.
b. Install the bearings in connecting rod and
rod cap.
c. Install the connecting rod and rod cap with
the index marks aligned as shown in
“Figure 79: Connecting Rod and Cap
Installation” on page 53.
d. Install the connecting rod nuts and torque
them to 25.0 ft-lb (33.9 N•m). Do not
allow the connecting rod to rotate on the
crankshaft rod journal.
e. Remove the rod cap and check the
plastigauge to determine the clearance of
the connecting rod bearing. The
recommended rod bearing clearance is
0.0008 to 0.0024 in. (0.0203 to 0.0610
mm).
Figure 78: Check Plastigauge
14. If the rod bearing clearance is too large, use
undersize bearings and have a competent
machine shop grind the crankshaft to fit the
undersize bearings.
Assembly
1. Place the piston on the connecting rod and
install the wrist pin and the snap rings.
2. Install the bearings in connecting rod and rod
cap.
3. Apply apply refrigerant oil to the piston and
place it in the sleeve.
4. Place the piston and sleeve in the compressor
body. Take care to prevent damage to
crankshaft from the rod bolts. Install the rods
so the index marks face the other rod on the
same rod journal. See “Figure 79: Connecting
Rod and Cap Installation” on page 53.
5. Install the connecting rod cap. Make sure the
index mark on the cap is aligned next to the
index mark on the connecting rod as shown.
Index marks may point toward the front or
rear of the compressor.
6. Install the connecting rod nuts and torque
them to 25.0 Ft-lb (33.9 N•m). Rotate the
crankshaft after each rod assembly is torqued
to check that the components move freely.
