## NHTSA's summary

This Technical Service Bulletin announces a new heavy duty tapered bearing fan support in place of the standard duty fan support. Certain applications have seen an increased number of standard fan support bearing failures. The heavy duty fan support is better suited for applications with increased failures of standard fan supports. The new heavy duty tapered bearing fan support is a bolt on replacement for the standard support. This is an update to a previously submitted communication.
