Connecting Rod Cleaning Procedure; Connecting Rod Measurement Procedure - Suzuki XL7 2007 Service Manual

1D-174 Engine Mechanical:
3. There is a locating dimple (1) on the compression
rings near the end for identification. Install the
compression rings with the dimple facing up.
4. If the new ring does not reduce the clearance to the
proper specification, install a new piston.
5. If the new piston does not meet clearance
specifications, the cylinder block may need to be
oversized to 0.25 mm (0.010 in). There is only one
size of oversized pistons and rings available for
service.

Connecting Rod Cleaning Procedure

1. Clean the connecting rods in solvent.
WARNING
!
Refer to "Safety Glasses Caution: ".
2. Dry the connecting rod using compressed air.
3. Remove the connecting rod cap and clean the
threads.
4. Remove the connecting rod bearing and discard.
Never reuse a connecting rod bearing used in a
running engine.
Connecting Rod Visual Inspection Procedure
1. Inspect the piston pin bushing (4) for scoring or
damage.
2. Inspect the connecting rod beam (1) for twisting or
bending.
3. Inspect the rod cap (2) for any nicks or damage
caused by possible interference.
4. Inspect for scratches or abrasion on the rod bearing
seating surface.
NOTE
DO NOT scrape the rod or rod cap.
5. If the connecting rod bores contain minor scratches
or abrasions, clean the bores in a circular direction
with a light emery paper.

Connecting Rod Measurement Procedure

Piston Pin End
NOTE
Measurements of all components should be
taken with the components at normal room
temperature.
1. Using an outside micrometer, take 2 measurements
of the piston pin in the area of the connecting rod
contact.
2. Using an inside micrometer, measure the connecting
rod piston pin bore.
3. Subtract the piston pin diameter from the piston pin
bore.
4. Compare the clearance measurements with the
"Engine Mechanical Specifications".
