Make a note of the article"Fan V-Belt Part Number Has Changed For Certain Models With The 3204 Engine"in this issue.
--------------- END SUPPLEMENT ---------------Description of Change: All of the above machines equipped with the 3204 Engine have had a V-Belt part number change. Adaptable To: If the machine is equipped with a 3204 Engine and a 7N-5141 Fan Drive Group, the 8N-2818 V-Belt previously used has been canceled and replaced by an 8M-8336 V-Belt. Please make note of this in your parts books and service manuals.
The New Product Release will guide you to purchase an 8N-9004 Alternator Support Bracket Assembly if purchasing an 8M-8336 Fan Belt in place of the cancelled 8N-2818 Fan Belt. The 8N-9004 Alternator Support Bracket Assembly is a Parts Service bracket which is heavier than the 8N-2821 Bracket Assembly. This 8N-2821 Bracket Assembly was used on the early D3B, D4B, 931B and 935B models. The new bracket assembly may be purchased to replace the 8N-2821 Bracket Assembly used on earlier machines if desired.
The 8M-8336 Fan Belt will fit with the machine previously equipped with an 8N-2820, the Parts Service 8N-9003 of the later 1W-4267 Alternator Support Castings.
