Introduction
The problem that is identified now has a known permanent solution. Components to perform repairs are limited at this time. Review the solution below for further details. Problem
Caterpillar is aware of recent failures of the 8N-1721 Connecting Rod and the 8N-1984 Connecting Rod on certain diesel and gas applications of 3300 engines. Primary failure mode is a ventilated cylinder block due to the connecting rod crank end failure. All failures have occurred before 500 hours in service. Root cause has been identified and the team is working to resolve the issue. Solution
A "Quality Hold" is active for all new assemblies that utilize the 8N-1984 Connecting Rod and the 8N-1721 Connecting Rod manufactured between 01April 2011 and 31December 2012. The "Quality Hold" is applicable to all Morton service stock also.Cat ® Reman has identified a list of part numbers for Service kits, Piston Packs, and Rod Assembly boxes that may contain defective factory connecting rod assemblies. Dealers are advised not to use any factory new connecting rod assemblies that are found in the kits or assemblies prior to examination. Refer to Table 1.
