How to Replace a Damaged AH143573 Knife Guard for John Deere Combine Harvesters

Replacing a damaged knife guard on a John Deere combine harvester can be a simple process if you have the right tools and knowledge. In this guide, we will explain step-by-step how to replace an AH143573 knife guard for John Deere combine harvesters.

Step 1: Safety first

Before starting any maintenance work on your machinery, always make sure that it is turned off, and the keys are removed from the ignition. This will prevent any potential accidents or injuries while working on your combine harvester.

Step 2: Remove the damaged knife guard

The first step in replacing a damaged knife guard is to remove the old one. To do this, you will need to locate the damaged knife guard and loosen the bolts that hold it in place. You can use a socket wrench to remove the bolts, and make sure to keep them in a safe place for later use.

Step 3: Clean the knife holder

With the damaged knife guard removed, you will now need to clean the knife holder thoroughly. This will ensure that there is no residue or debris left behind that could interfere with the new knife guard's installation.

Step 4: Install the new knife guard

After cleaning the knife holder, you can now install the new knife guard. Start by positioning the new knife guard in place, and then attach it with the bolts that you removed earlier. Make sure to tighten the bolts securely.

Step 5: Check the alignment

With the new knife guard in place, you will need to check its alignment to ensure that it is positioned correctly. You can do this by turning the combine harvester's rotor by hand and checking the knife guard's clearance. If the clearance is too tight or too loose, you may need to adjust the knife guard's position, so it sits correctly.

Step 6: Reassemble the combine harvester

With the new knife guard in place and correctly aligned, you can now reassemble the combine harvester. This involves putting back any parts or covers that you removed earlier, such as the panels or shields.

Step 7: Test the combine harvester

Before using the combine harvester, you will need to test it to ensure that it is working correctly. Start the combine harvester, and then allow it to run for a few minutes to ensure that everything is working as it should.

Step 8: Clean up

Finally, clean up your workspace and dispose of any old parts or debris safely. You can now use your combine harvester with confidence, knowing that it has a new AH143573 knife guard installed.
