Have been attempting to find the correct replacement belt for my 01 455 Marquis with numbers in the manual that read;
Dayco 20-9205 and Magnum 0201147.
After a great deal of research I found the following which will apply to ALL BEAVER OWNERS that are having problems with looking for Dayco numbers.
The Dayco 20-9205 is the serial number, the Magnum 0201147 is the part number. Dayco has discontinued these belts BUT,
Ms. Pat Hopper of Dayco Tech Support 1 800 331-7230 says her department wrote the specs for the Beaver belts and has the information that relates to size and ribs.
They can't give you a replacement, but with the EXACT size and ribs you can get NAPA or similar outlet. (by the way Gerald, thanks for your help and yes I did try Bend Parts first. They had nothing)
The NAPA/Gates belt that is the replacement for my Magnum part #0201147 is 25-081153. The 08 is for 8 ribs, the 1153 is for 115.3".
Ms. Hopper said she would be more than happy to assist anyone who calls her with a engine belt problem.
Good luck.
