SERVICE BULLETIN
Subject: Fan motor bracket change
The fan motor mounting bracket for the FME800, FME804, NME650 and NME654 has been changed.
The prior part, 02-2378-02, will no longer be used for production or as a service part.
The new part number is A38850-001, which is a sheet metal type bracket. In new units it will be connected to the fan shroud with 1/4 - 20 screws, pn 03-1645-01.
When replacing a prior bracket, use the original #8 screws but place a #8 flat washer under the head of the screw to prevent it from pulling through the bracket's clearance hole.
Production of NME654 with the new bracket began with serial number: 05051320012877 Production of FME804 with the new bracket began with serial number: 05051320013382
