Removing the Old Mower Belt

Begin by ensuring the mower is completely powered off and the spark plug wire is disconnected to prevent accidental starting. Position the mower on a flat surface and, if necessary, tilt it carefully to access the underside where the belt is located.

Locate the belt deck and the pulleys that guide the belt. The mower belt 174368 typically runs around the engine pulley, idler pulleys, and the blade pulley. Before removing the belt, take note of the belt routing or refer to a belt routing diagram specific to your mower model.

To remove the old belt, release the tension by loosening the idler pulley. This often involves using a wrench or socket to rotate the idler pulley arm to relieve tension on the belt. Once the tension is released, the belt can be slipped off the pulleys. Pay attention to any clips or guards that may need to be removed to free the belt.

Dispose of the old belt properly, as worn or damaged belts can cause mower malfunction or safety hazards if reused.

Installing the New Mower Belt 174368

When installing the new belt, confirm it matches the specifications for your mower model. The mower belt 174368 is designed to fit specific pulley sizes and layouts, so incorrect belts can lead to slippage or damage.

Follow these steps to install the new belt:

  • Route the belt according to the mower’s belt path diagram.
  • Place the belt around the engine pulley first, then around the blade pulley.
  • Loop the belt over the idler pulleys, ensuring it sits correctly in the pulley grooves.
  • Apply tension by moving the idler pulley arm back to its original position, ensuring the belt is taut but not overly tight.
  • Reattach any belt guards or clips that were removed during disassembly.

Check that the belt moves freely and does not rub against any mower parts. This will help prevent premature wear.

Testing the Belt Installation

Before resuming normal mower operation, perform a functional test to verify the belt installation:

  • Reconnect the spark plug wire.
  • Start the mower engine and observe the belt’s movement.
  • Listen for unusual noises such as squealing or grinding, which may indicate improper tension or misalignment.
  • Engage the mower blades to confirm they rotate smoothly.
  • Shut off the mower and inspect the belt for any signs of slipping or misplacement.

If any issues are detected, turn off the mower immediately and recheck the belt routing and tension.

Step-by-Step Procedure for Removing the Old Mower Belt 174368

Proper removal of the old belt is essential to avoid damage to mower components and to facilitate an easier installation of the replacement belt. Follow the steps carefully:

  1. Access the Belt: Remove the mower deck if necessary. This may involve loosening bolts and detaching linkages that connect the deck to the mower frame.
  2. Release Belt Tension: Locate the belt tensioner pulley. Use a wrench or lever to move the tensioner, relieving tension on the belt.
  3. Remove the Belt: Slide the belt off the pulleys starting with the tensioner pulley, then the drive pulley and spindle pulleys. If the belt is damaged or stuck, carefully cut it with a utility knife.
  4. Inspect Pulleys and Components: Check all pulleys, tensioners, and bearings for wear or damage. Replace any defective parts before installing the new belt.

Installing the New Mower Belt 174368

Installing the new belt requires attention to routing and proper tension to ensure optimal mower performance and belt longevity. Refer to the mower’s belt routing diagram, often found on the mower deck or in the owner’s manual, to correctly position the belt.

Step Action Important Notes
1 Route the belt around the main drive pulley. Ensure the belt sits in the pulley grooves without twisting.
2 Loop the belt around the spindle pulleys on the mower deck. Follow the specific path indicated in the mower’s schematic.
3 Engage the belt with the tensioner pulley last. Use the tensioner arm to allow the belt to fit comfortably.
4 Release the tensioner to apply proper tension on the belt. Check for appropriate tightness; the belt should have minimal slack but not be overly tight.

After installation, manually rotate the pulleys to ensure the belt moves smoothly without slipping or binding. Reinstall the mower deck if it was removed, securing all bolts and linkages properly.

Testing and Final Adjustments

Once the mower belt 174368 has been installed, perform the following steps to verify correct installation and operation:

  • Reconnect the spark plug wire to restore engine function.
  • Start the mower engine and engage the blades.
  • Observe the belt: Listen for unusual noises such as squealing, which may indicate improper tension or misalignment.
  • Inspect blade rotation: Blades should spin smoothly and at consistent speed without stalling or jerking.
  • Check belt tension again: After a short run, power down the mower and recheck belt tension, adjusting if necessary.

Proper maintenance of the mower belt will extend its service life. Periodically inspect the belt for signs of wear, cracks, or glazing, and replace it when these symptoms appear.
