Craftsman LT2000 Drive Belt Diagram(Fixed)

If you own a Craftsman LT2000 lawn tractor, it’s important to know how to properly maintain it to ensure it runs smoothly and efficiently.

One crucial component of the LT2000 is its drive belt, which helps transfer power from the engine to the transmission.

In this post, we’ll provide a detailed Craftsman LT2000 drive belt diagram and explain how to replace the drive belt yourself.

Let’s dive in.

Craftsman LT2000 Drive Belt Diagram

Before we dive into the steps for replacing the drive belt, let’s take a closer look at the Craftsman LT2000 drive belt diagram.

The LT2000 has two belts: a ground drive belt and a mower drive belt.

The ground drive belt is responsible for transferring power from the engine to the transmission, while the mower drive belt powers the blades.

Here’s a breakdown of the Craftsman LT2000 drive belt diagram:

  • Engine pulley: This is where the ground drive belt starts. The engine pulley is attached to the engine’s crankshaft and spins as the engine runs.
  • Idler arm: The idler arm is a pulley that helps guide the ground drive belt and keeps it tight. It’s attached to a spring that helps maintain tension on the belt.
  • Transmission pulley: This pulley is located on the transmission and receives power from the engine via the ground drive belt.
  • Mower deck pulleys: The mower deck pulleys are where the mower drive belt begins. There are usually two pulleys on the mower deck that the belt wraps around, and they help power the blades.

How to Replace the Craftsman LT2000 Drive Belt

Replacing the drive belt on your Craftsman LT2000 is a relatively straightforward process. Here are the steps you’ll need to follow:

  • Disconnect the spark plug wire to prevent accidental starting.

  • Remove the belt from the engine pulley by carefully slipping it off.
  • Install the new drive belt on the engine pulley, making sure it’s properly seated.
  • Route the new drive belt around the mower deck pulleys in the same pattern as the old belt. Make sure it’s properly seated on each pulley.
  • Pull the arm toward the back of the mower and slide the belt over the pulleys to reattach the belt to the idler arm.

Craftsman LT2000 Drive belt Replacement

Here are the general steps to replacing the drive belt on a Craftsman LT2000:

1. Park the tractor.

Make sure the tractor is on a level surface and engage the parking brake to secure it.

2. Remove the mower deck.

Depending on your specific model, you may need to remove the mower deck to access the drive belt. This is usually done by disengaging the belt tension and removing the deck from the brackets.

3. Locate the belt routing diagram.

There should be a belt routing diagram on the tractor, typically located near the pulleys. If not, consult the manual or search for the LT2000 drive belt diagram online.

4. Loosen the belt tension.

There is usually a belt tensioning system that needs to be released to relieve tension on the old belt. This can involve loosening an adjustment bolt or releasing a tensioning lever.

5. Remove the old belt.

Carefully slide the old belt off the pulleys, making sure to note its routing according to the diagram for later installation.

6. Install the new belt.

Following the belt routing diagram, slide the new belt onto the pulleys.

7. Re-tension the belt.

Use the belt tensioning system to tighten the new belt properly. Ensure there is enough tension to prevent slippage, but not so tight that it causes strain on the components.

9. Reattach the mower deck (if applicable).

If you removed the mower deck, now is the time to reattach it and secure it back onto the brackets.

10. Test the tractor.

Start the engine and engage the drive to check if the new belt is functioning correctly. Listen for any unusual noises and ensure the tractor moves smoothly.

11. Adjust if necessary.

If the belt is not running smoothly or you notice any issues, double-check the routing and tension of the belt. Make adjustments as needed.
