Question about Garden
Judging by the diagram the spring mounts under the armbrake, the Bolt (#52) goes through the circular spring. One end of the spring goes into one of the holes near the bolt on the armbrake and the other ( after providing tension by turning the spring ) must attach to a non moving part on the deck to be able to provide the required tension Look for a small turned up piece of metal with a notch in it on the housing.
Hope this helps

Place the deck in the lowest position using the hydraulic piston (if applicable) or the manual cutting-height adjuster.
Remove the deck-to-PTO belt from the PTO by releasing tension on the idler-arm pulley. This is a spring-loaded handle that turns in only one direction by hand and relieves the tension on the belt. Slip the deck-to-PTO belt off the PTO pulley after the tension is relieved.
Remove the deck from underneath the mower or tractor.
Locate any belt stops and loosen them with the ratchet wrench and proper socket. Belt stops are located on the deck and are the small metal brackets that guide and secure the belt to the pulleys so it will not jump off when under heavy use, or stretch from normal wear.
Remove any pulley covers by removing the retaining screws using the ratchet wrench and a socket.
Loosen the idler-pulley retaining bolt (located on the underside of the mower deck) to replace the deck-to-PTO belt. Removing the bolt is not necessary. Loosen the pulley enough to wiggle the belt free from the pulley and remove and replace the belt.
Remove any arbor covers (if applicable) that conceal the arbor pulleys by removing the retaining screws with the ratchet wrench and a socket to replace the mower arbor belt.
Locate the tensioner pulley on the mower arbor belt to replace it. Loosen the tensioner pulley bolt enough to slide it and release tension from the belt. Remove the belt from the arbor pulleys and replace it.
Slide the tensioner pulley back leaving about 1/2-inch of play in the belt and tighten the bolt. Reverse the procedure to put the rest of the mower deck back together and reinstall on the mower or tractor.
