Item
Examine the
connecting rod
bushing for damage.
Examine the Connecting Rod Bushing for Wear:
(1) Measure and record the Inside Diameter (ID) of the
connecting rod bushing.
(2) Measure and record the Outside Diameter (OD) of the
piston pin.
(3) Calculate and record the clearance by subtracting the OD
of the piston pin from the ID of the connecting rod
bushing.
• If the clearance is less than or equal to the "Service
Max." clearance in the latest revision of the Service
Table of Limits - SSP-1776, the connecting rod
bushing and piston pin are acceptable with regards to
connecting rod bushing wear.
• If the clearance is greater than the "Service Max."
clearance in the latest revision of the Service Table of
Limits - SSP-1776, remove, discard and replace the
component(s) that exceed(s) the manufacturing
dimensions according to the latest revision of the
Service Table of Limits - SSP-1776.
