On my 128, there is one 1/4 inch groove worn in the front axle from the mule drive belt. The only time the belt comes in contact with the axle is with the mower(38 inch) in the fully raised position with the PTO engaged. Dad said the original belt did the same from brand new<!-/quote-!><hr size=0></blockquote>
That's very interesting indeed....
I don't know what differences, if any, there might be between your CC 128, mule drive with a 38" deck and my CC 127, mule drive with a 42" (deck P/N 42U113) mower deck set up, but I can tell you this: with the PTO engaged, I can raise my deck all the way up or down and my front mule pulleys are ~1/2" away from touching the front axle when on the level. A good share of my mowing is with the deck all the way up (due to uneven ground) and altough it is rough, hilly and bumpy ground, the axle has NO cuts in it to date.
I believe my center deck pulley is OEM and I'm running a 1/2" x 82" PTO-to-deck (main drive) belt and the tensioner nut "K" (located at the front hanger) adjusted to provide 3-5/16" distance from center of the mule drive pulley to inside surface of the hanger. For reference
, this measurement is outlined at Illust. 3-6 on page 3-7 of the Blue Ribbon Service #GSS-1398, IH Service Manual for Cub Cadets, 72, 104, 105, 124 & 125 and IH Equipment.
