O.K. I"m starting to gain a tiny irritated. The belt on mine 50" gravely deck has damaged for the second time (after about 8 hrs usage each time). I tightened the idler to factory spec. Each time v the very same results. Any type of input/diagnosis would certainly be appreciated.

I believe I"m making use of a Sten OEM belt. Just how do I inspect for suitable alignment? I"m pretty lot a noob v Gravely"s and also learning as I walk so pardon me because that stupid questions.

This for the driver in avatar? I would pull out the deck, remove covers to see good. Turn each spindle and also see if nice and smooth and also loose, or kinda binding. Likewise wiggle them to see if any large play in them. The idler eight on plenty of decks rusts in ~ it"s pivot. If not basic moving, take it it off, clean up the pivot bushing till nice and totally free moving, bolt ago down. Make sure any kind of washers or spacers go back in orig an are or that will just tighten once bolting down, no what is need to do. Make certain that very same tension eight is no bent out of alignment. Look at for whereby the belt rides on that pulley-block if a flat one. Make certain that pulley also spins smooth and also easy. Most times negative pulleys just obtain replaced, have actually sealed bearings made right into them.NOW, simply realizing you may be talk the drive belt? about same things, make certain all the pulleys relocate freely and also with no big play. Grease castle if required? This deck must have a Mule journey with dual pulley device to drive? i don"t know what Gravely"s actually have. All the stress and anxiety arms need to move and also float, one usually has actually a feather for tension, other has the eye-bolt because that tensioning?? Make sure all pulley"s straight and no knicks or bends at outer edges that reduced into belts. Is there tiny metal bars or rods to help guide the belt, store it on pulleys when it is loose? missing ones may allow belt to relocate off the pulley some, then as soon as you connect it type of starts, but rolls over a spicy edge or something before seating? The guides protect against that. You have actually a hands-on for the deck? finest look into one if not, a parts and also owner"s users" if seperate. Examine the diagrams with what you are doing or owning.
