TALMADGE 71 #1 Posted May 9, 2016 (edited) is 300 too much and what do i need to look for as far as what breaks first on these things?? and will it fit the 520H Edited May 9, 2016 by TALMADGE Share this post Link to post Share on other sites
doc724 924 #2 Posted May 9, 2016 Not much breaks but the seals will leak. Times should be squarish at ends, not like shark fins. If sharkfins, the tines are worn out. Make sure there is a mid idler with tension spring. Belts are expensive. A helper spring is not needed for hydro. Share this post Link to post Share on other sites
TALMADGE 71 #3 Posted May 9, 2016 Thank You sir. Im kinda lost on mid idler. Is that the pulley assembly on the front side that operates the tiller. Share this post Link to post Share on other sites
WHX?? 46,404 #4 Posted May 9, 2016 Mid idler would be the assembly that's fits in the miidle right side attach bracket.and strings the belt waaaaay back to the tiller. Not the worst price if in decent shape like doc says says.It might fit a 520 but would need the model to be sure. Share this post Link to post Share on other sites
312Hydro 473 #5 Posted May 9, 2016 (edited) That will fit a 520h. Here is a pic of the mid mount idler. You can easily make a variation of one,just do a search on the forums Edited May 9, 2016 by 312Hydro 2 Share this post Link to post Share on other sites
