Question about Garden
Craftsman lt3000 42" mower deck. replaced pto clutch cable..and installed the new carriage bolt included in the kit, however had a terrible time removing the locking nut from the old carriage bolt and a difficult time tightening that nut on the new bolt. I finally used vise grips to hold the bolt and the pulley guard tight to the idler arm because it didn't matter if the bolt got screwed up...now I want to replace idler arm and brakes and have gotten bolt most of the way off, but can't find a way to hold that bolt and guard close to the idler arm to finish the job...got to be a trick to this, but I haven't found it

Compare the new pulley to the old one. I think you'll find you have been supplied with the wrong pulley.
Very best regards

I think your best bet would be a junkyard or used parts like You Pull It.There seems to be no store that has the bolt. there are plenty that have the pully.

>>You have to Hold the Shaft on the Blade Side with a Pipe or Strap Wrench or Depending on the Model, you can Block the Blade an Hold the Shaft so the Pulley Nut can be Loosened/Removed.

I have the exact same model MTD tractor with same problem. It began when the bolt that extends through the idler arm assembly broke and subsequently damaged the pulley. Upon examination of the broken bolt, I found that the threaded end that extends below the deck is significantly smaller that the rest of the bolt. I got a larger bolt with the same size threads, bored out the hole through the deck and it made the whole idler assembly much stronger. the deck still has some vibration and some unusual belt harmonics, but it appears to be working. Compared to most other tractors of this size, this deck is very complicated.

Did you obtain the correct replacement belt AND pulley. Double check your part numbers against the parts list for your machine. If you verify that they are correct, double check the belt routing, make sure it didn't get on the wrong side of a belt guide and is in the correct configuration. Look at your idler pulley and make sure the release spring is doing its job pulling it back from the applied position. Make sure that the arm for the pulley moves freely where it is bolted to the deck, it could be bound up with rust or debris. You should have a lot of slack in the belt when it is in the released position. If it does not then either it is the wrong part or improper installation

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.
