erjarrett Report post Posted March 30, 2017 Just recently converted the CAT C7 sealed fan bearing to a bearing that can be lubricated. If interested see attached file. Ray CAT C7 FAN BEARING REPLACEMENT VER_1.pdf Share this post Link to post Share on other sites
wolfe10 Report post Posted March 30, 2017 Very nice job of documenting the conversion. In order of reliability: Greasable that is greased. Sealed Greasable that is NOT greased. Be sure to purge all air out of the grease hose extension before installing it to the fan hub. Share this post Link to post Share on other sites

jrock Report post Posted March 30, 2017 That opening looks like it gives really good accessibility to the front of the CAC for cleaning Share this post Link to post Share on other sites
