The LT 1554 Cub Cadet idler spring is connected on the idler bracket at one end and to a special bolt under the left blade pulley cover on the other end. The easiest way to reconnect the spring is to:
-Remove the left cover over the left blade drive pulley (three bolts)
-Connect the spring to the idler bracket
-Connect the other end of the spring over the tall bolt under the cover
-Reinstall the cover
This is probably the large spring that tensions the idler pulley assembly for the main drive belt (the belt that runs whenever the engine is operating and runs between the upper engine pulley and the pulley on the transmission. It hooks on the idler pully assembly on the left side of the mower and then on a vertical bracket toward the front of the mower. You'll need a big screwdriver to get it back on. Put a socket wrench on one of the idler pulleys and pivot the entire idler assembly to release tension on the belt so you can snap the spring back in place with the screwdriver. Uncle Al
This is real easy on the 3.8 L engine Whether its front wheel drive or rear wheel drive all you have to do is locate your idler pulley and use a wrench that is the size of the nut on the idler pulley and move the idler pulley just enough to pull the belt off. Be careful to release the tention on the idler pulley slow it is under spring pressure. Use schematic under hood to put on new belt. This will take about 5 minutes to complete. Hope this helps.

The serpentine belt tension is not adjustable. It is set by a spring loaded idler pully. "Idler" just means that it is not used to drive anything. It is spring loaded to tension the belt and control belt position. The bracket for the idler pully has a square hole in it that is used to compress the spring during belt installation or removal. You can put a 1/2" drive ratchet or breaker bar in the square opening and apply pressure against the spring to remove the old belt or install a new one. Ratchets and breaker bars are normally used with a socket to loosen nuts, but no socket is required to use them in the idler pully bracket. If your belt is making noise or looks loose it probably needs to be replaced. Typical belt life is 3-5 years. The tension is set with an automatic tensioner. It must be replaced.
== == it is a free pulley that works as a tensioner on any belt bolted to hold or spring loaded An idler pulley usually tensions a belt.. eg supercharger belt is kept taut by its respective idler pulley
Disengage the idler arm lever ( it is a spring loaded arm located on your deck on left side). There is a bracket that holds it in place. Push arm forward over bracket then carefully allow arm to release all the way back. This will remove tension from belt. Then simply slide belt over pulleys keeping track of how they are aligned on pulleys. When installing new belt be sure belt is aligned in both front pulleys and be sure all belts are set in pulleys before reengaging idler arm lever.
Most rear wheel drive Pick up trucks with manual transmission have an idler to provide reverse.
Most idler pulley's are near the top and usually quite easy to get to. Press on the belt somewhere, enough to deflect it a couple inches and watch to see which pully is mounted on a tension spring. That is the idler pulley.

The 2006 Chevrolet Silverado four-wheel-drive pickup truck item idler arms are sealed. There are not any grease zerts. The idler arm will need to be replaced.
An idler pulley is a pulley that does not drive and is not connected to any device that is driven. It serves to either tension a belt or to route a belt to clear an obstacle.
