This is a genuine part that is sourced directly from the original equipment manufacturer for use with Murray lawn mowers and garden tractors. It is the part that helps to apply tension on the transmission belt. Over time it may wear out or get damaged eventually requiring a replacement to ensure your equipment runs great. Keep in mind this high-quality component is made of durable materials and is sold as an individual item. Check the owners manual and the diagrams of your model for the exact location and the correct installation of this pulley. You will need a wrench set to remove the old pulley and secure the new one.

Raise front of Murray tractor by using ramps or a jack and jack stands. Put wheel chocks on both sides of the tires to prevent any movement. Push brake/clutch pedal all the way down and engage parking brake. This will take belt tension off of the idler pulley so it can be easily removed and a new one installed. Lower the mower deck as

Install new pulley and reinstall the nut. I did not have information on how much torque to apply to the nut so I tightened it to a point where I felt it was not over tightened. .Undo the parking brake and carefully bring the tractor back down to the ground and you\'re good to go.
Note: You should examine the drive belt for any damage the frozen idler pulley bearing may have caused to the belt and replace it if necessary. Replacing the drive belt is a major task and I was lucky my drive belt was o.k. for a few more years.
I really appreciated that eReplacement Parts had an OEM part for my 20 year old Murray tractor.

Pulled the spring tensioned arm back and held it with a screw driver (long one).
Took the lock nut off.
Found spacers at local hardware store and had to put 5 or so washers below the pulley. This was necessary to make the pulley high enough to not pull the belt off.

It was hard to work in the confined space - my arms barely fit in there. Had one wheel off in the rear and had it up on jack stands.

Motion belt, idler pulley and mover deck belt worn out.
Removed the mower deck, lifted front end of lawn tractor, removed belt guides front and rear. Removed idler pulley, loosened bracket above the trans axle pulley, a spring, and shift linkage.
