I have an older simplicity regent lawn mower deck # 1693792. When i engaged the deck it made a loud noise and when i looked under the belt was off the pulleys and the tensioner pulley/pulley mount was bent. Also the belt was double wrapped around the pto clutch pulley. I figure the belt was worn out, so i bought a new belt and straightend the tensioner. Started it and engaged the deck and the same thing happened. Any help is greatly appreciated. Thanks Kevin

Make sure all your blades move freely. Check all pulleys as well.

When was the last time you checked the idler pulleys and bearings and the spindle pulleys and bearings for wear or sloppiness. If it has been more than three years, that is where I would start. Also, you said you straightened the tensioner arm. Are you sure that all pulleys are level and aligned? These are a few things that will cause a thrown belt.

Before I put the new belt on i checked each pulley, they all spun freely. The one blade pulley is starting to make a little noise though. I checked them with a straight edge, but they weren't perfect. The one that was bent was off on one side by about 1/16th of an inch. Is this normal for a belt that comes off to bend a pulley?

Your deck was used between 2001-04, which makes it at least 10 years old. If you have never changed any of the pulleys or bearings, I would say now is the time. Throwing belts is the first sign of wear.

Please note: 1693792 is deck model #, you need to use Simplicity tractor model number when ordering parts or posting.
Had same problem with my tractor two years ago. Pages 32 & 33 illustrated parts breakdown & parts list with numbers will be helpful. Remove deck and inspect clutch lever assembly for being cracked, if so you can take it to auto repair shop and have them weld lever or purchase a new one. I would disassemble parts 1-16 and parts 1-10 and inspect for worn out parts, example: bolts bent, bushings, idler bearing worn out, this is where you're problem is. If it were me, I'd order part # 25 clutch lever assy. w/ bushings 1704520, #1 capscrew grade 8 1928957 two each, #11 washer 3/8 1924356, #15 spacer 1657242, #16 nut 1960339, #5 idler 1685150, #9 spring 1715435, #3 spring guard 1677135, #8 nut 1916950, # 10 nut 1919439, #2 washer 1922755, #7 lockwasher 1916965, #26 belt, you'll be be in good shape.
Tractor Parts This is a good time to clean topside & underside of deck, remove, clean, inspect, and dress up blades with file & balance blades, page 37 items 20 & 21 and replace if necessary. Also replace drive belt from engine to transaxle. Grease arbors at fittings as well as entire tractor. Before reinstalling deck, use oil squirt gun or grease on all moving parts, and lastly apply grease liberally to sector & pinion gears on steering shaft. Avoid getting grease or oil on belts, wipe off immediately.

I have the deck disassembled, it was in rough shape. Going to do a complete overhaul and hopefully this will solve my problem. Thank you for your help.
