When reinstalling, make sure that cylinder numbers put on the
connecting rod and cap at disassembly match. When a new connecting
rod is installed, make sure that the notches for holding the
bearing in place are on the same side.
|
| (2) |
Replace the connecting rod if it is damaged on the thrust faces
at either end. Also if step wear or a severely rough surface
of the inside diameter of the small end is apparent, the rod
must be replaced as well.
|
| (3) |
Using a connecting rod aligning tool, check the rod for bend
and twist. If the measured value is close to the repair limit,
correct the rod by a press. Any connecting rod that has been
severely bent or distorted should be replaced.
|
Allowable bend of connecting rod :

|
|
| (7) |
If the plastigage shows the clearance is still incorrect, try
the next larger or smaller bearing. (Refer to crankshaft main
bearing selection table in this Group).
Recheck the oil clearance.
|
If the proper clearance cannot be obtained by using
the appropriate larger or smaller bearings, replace
the crankshaft and start over.

|
If the marks are indecipherable because of an accumulation
of dirt and dust, do not scrub them with a wire brush
or scraper. Clean them only with solvent or detergent.
