That there is a two-fer. ID'd the belt rub and the bad bearing. Win-win. 2 1 Share this post Link to post Share on other sites
Bar Nuthin 3,262 #28 Posted Monday at 02:01 AM Getting the belt guard aligned is a tricky proposition. There's very little clearance overall so a gain at one spot creates a tight spot somewhere else. Ended up bolting down the guard and running the engine, then tapping around with small rubber mallet until I found the sweet spot where the noises disappeared. Sometimes you just gotta go with what works. 2 2 Share this post Link to post Share on other sites
Bar Nuthin 3,262 #29 Posted 3 hours ago Update - so the belt guard gradually went back to its rubbing and belt slapping. The only way I could get the proper clearance was to remove the front bracket bolt. Seems great now, except the front bracket is about an 1/4" above the hole it bolts into. I tried bending it but that wasn't working out. The only solution I can think of is to separate the spot welds and relocate the bracket.

There was one with three lines on it and one plain and they are definitely different. Apparently 7 & 8 HP. One is larger on the SG pulley end for a larger pulley and more clearance overall. I think its the one with the lines. Looks like you have the plain one. We was just yakin about this i was having a fit trying to get one to quit rattlin. Here I had the wrong one.

Bar Nuthin 3,262 #33 Posted 1 hour ago Now that I've eliminated the hot spots and the belt slap. I think I'll go with the plan to separate the spot welds and relocate the bracket. Share this post Link to post Share on other sites
