pto belt comes off cub cadet model 123 with 42" deck
My pto belt keeps coming off. I have a cub cadet model 123 with a 42” mower deck (3 spindles). I have read many old posts on this site about this issue which leads me to believe I have a wrong belt or mule drive idler pulley or both. I have the telltale grooves in the front axle.
Questions:
1. What is the correct outer diameter of the mule drive idler pulleys?
I have one (the original I assume) that is ~3.3” OD and a replacement for one
that had a binding bearing that is 3.0” OD.
2. There are two holes in each side plate. What hole should the mule drive idler pulley rod be in and why are there two holes? One is more forward and down and the other is more back and up. (see attached image)
3. Could someone kindly verify that these part numbers I looked up are correct before I go ahead and order?
PTO to mower deck belt (3/8” W x 81” L): IH-473462-R4
mule drive idler pulley: IH-61176-C92
mower deck spindle drive belt (½” W x 77” L): IH-477599-R2
I’m not having a problem with the mower deck spindle drive belt but according to the part number I looked up, the one I’m currently using is 1” shorter than it should be and about 1/16” thinner in width so I may as well get the right one.
4. Where would you order these parts from?
a.) cubcadet.com
b.) ccspecialties.org
c.) messicks.com
d.) somewhere else
Thank you
