Things You'll Need
New motion drive belt
New mower drive belt
Craftsman DLT 3000 riding mowers make it manageable to have a large lawn. They allow you to cut the grass quickly and efficiently. After two years of mowing, the deck belts need to be replaced, as the belts will become misshaped through wear and tear. In order to safely replace the belts on a Craftsman DLT 3000, you must first remove the mower deck.
Remove Mower Deck
Position the attachment clutch deck into disengaged position. The clutch is located under the steering wheel.
Position the attachment (deck) lift to its lowest position. The attachment lift is the large lever on the right side of the deck. Place it as forward as it will go.
Remove the belt off the engine pulley. The engine pulley is located directly under the engine. Pull the belt that is wrapped around it.
Remove the retainer rings, anti-sway bar connecting the deck's center to the mower's frame.
Raise the deck lift up so the suspension arms are out of the way.
Move the deck away from the mower and onto a flat surface where the belts can be changed.
Replace Mower Blade Drive Belt
Unwrap the belt around the two pulleys on the left and right portions of the deck, which are called the right and left mandrel pulleys.
Remove the belt off the middle pulleys, which are called the idler pulleys.
Pull belt away from the deck.
Place the belt around the right and left mandrel pulleys.
Place the belt around the inside of the mandrel pulleys.
Replace Motion Drive Belt
Look under the motor. There will be a belt wrapping around pulleys in between the rear tires and under the motor. Remove the belt from the clutching and stationary idler pulleys--the pulleys directly behind the pulley under the engine.
Pull the belt off the engine pulley. The belt is only attached to the rear pulley, which is called the transaxle pulley.
Wrap the belt around the transaxle pulley.
Place the belt around the inside of the stationary idler and around the outside the clutching idler. Continue wrapping it around the engine pulley.
Replace Mower Deck
Place the deck away under the mower.
Lower the deck lift.
Reconnect the retainer rings, anti-sway bar to the center of the deck.
Replace the belt around the engine pulley.
Reengage the deck by positioning the attachment clutch upwards until it locks into place.
DLT 3000 tractors were made for a few years and the parts were changed over the years. Make sure you purchase the correct belts.
Wear gloves to prevent your hands from being pinched.
