Phan 14 #1 Posted September 29 Hello, I am wondering when I should replace a drive belt / engine belt. My B100 has uncomfortable noises (not from the engine) but from the belt. I found the replacement part for the belt is Toro 7473: OC measures 82" and Top 5/8". Also, I need a mower deck belt model 0537sc03 serial 1051044. My belt of this mower is OC length 143" Top 3/4" which I use for 312-H. It is appears incorrect ??? I found that the belt should be OC length 141" Top 1/5". Please see below. Does anyone have any opinions? Does anyone have any opinions? Share this post Link to post Share on other sites
peter lena 8,682 #2 Posted September 30 @Phan belt driven issues are also related to ROUGH PULLEY ISSUES ! thats the rotational / movement drag , would personally go over every movement point , ROUGH / RUSTY / NOISY ? lubricaTE AND REPLACE AS NEEDED . BELT IDLER PULLEYS , are a heads up on to related SPINDLES , that 37 " deck is known for issues , would try to get a 36" R/D deck or a 42" s/d deck that will easily hook up to your tractor , the hitch on your tractor , is very easy hook up on other decks , pete Share this post Link to post Share on other sites
gwest_ca-(File Mod) 11,078 #3 Posted September 30 The 05-37SC03 uses a regular 4-sided belt. There should be flat idler pulleys for the wide back side of the belt. Drive and spindle belt 110265 (1/2" x 141.00") 1 Share this post Link to post Share on other sites
