I removed deck from mower so I could see moving parts better. I am 73 years young and laying on my side looking under mower was not my cup of tea. Upon removing deck I could see the results of 11 years of use. The parts were worn extremely bad and were hanging up and not releasing the Idler pulley when moving lever to dis-engage blades
... Read more. I should have ordered 2 Arm assembly Pad Brake but as it turned out one was not worn as bad as the other. The job was relatively easy. Just removed spring tensions first and laid them aside. Proceeded to remove nuts from carriage bolt. Put new parts on and put deck under mower. Mowed an acre of grass and had no problems. On a parts quality note..... The Arm Assembly pad Brake has a bolt on end that has a roller on it that is used in the disengage mode. On the original arm it was a thru bolt with nylon lock nut. The new one is just pressed in and I think it should have been spot welded where it come thru the arm. Only time will tell. If a person has a welding machine I would highly recommend putting a spot weld there as that bolt at times will have a lot of pressure on it as it slides around the edge of idler arm.

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.
The day before heading out of town on business the idler pulley seized up. I dropped the 54\" mower deck and confirmed the problem. I ordered the parts which arrived the day I got home from my trip. The parts all went together as planned and with a new belt that I already had on hand I was back in business. I was happy I could \"get cutti

Mandrel pulley got loose and rounded out the internal shaft hole, threw pulley off balance, whicn in turn, caused mower deck to uncontrollably shake, with excessive noise.
