Hex Flange Locknut

1. lowered deck
2. threaded bolt thru top washer, pulley idler, belt guide into hole, then put on bottom washer and lock nut.
3. used socket on top nut and wrench on bottom nut (due to clearance).
4. Took a minute or 2 to get bottom items on and started.
5. everything thightened in 2 minutes
6. routed belt back on pulleys
7. done, works as expected

The plastic was worn away by the drive belt on the pulley causing vibration. The carriage bolt wouldn't hold in it's square hole and it was difficult to get the original locknut off. I had to lift the whole tractor off the floor in order to hold tension on the carrier and bolt to back off the locknut. Then it was easy.

1. Separated mower deck from lawn tractor and cleaned both units thoroughly.
2. Removed and replaced tractor mounted idler pulleys, since bearings were noisy.
3. Disassembled mower deck - opted to overhaul blade tower supports (3) to clean and renew lubrication. RECOMMEND REPLACING THESE PARTS AS A UNIT, instead of overhaul.
4. Bearing failure had caused hole in deck-mounted pivot support bracket for belt tensioner to become elongated - opted to do nothing at this time.
5. Replacement pulley on pivot support was not sized to accept 7/16" dia bolt!!! Hardened spacer washer hole was too small as well. Re purposed another bolt from the ordered parts, and added washers as necessary to allow pulley to track properly without binding against the tensioner arm.
6. Removed and replaced other pulleys and hardware (these replacement parts were identical to the removed ones).
7. Installed new belt as per diagram on belt slip cover.
8. Reinstalled mower deck underneath the lawn tractor.

Works great!

Snapped a new wheel on and the new flange lock attached. I am so glad I found this website to obtain the new flange lock. Finding the necessary part was so easy and ordering as well was easy. The parts arrived very quickly before the next mowing need actually. Price at this site was the absolute best. Very grateful for their service. Thank you
