- Firstly, park your Lazer Z on flat ground and turn off the ignition key.
- Next, set the parking brake and elevate the posterior of your mower with a jack if you have one. This will help you disassemble the clutch.
- Locate the clutch and take a photo to compare after replacing the clutch.
- Then unplug your mower’s battery connection.
- Look for the electrical connection of the Exmark PTO clutch near the engine’s chassis, detach the wire, and pass it through the frame to the mower’s bottom.
- Gently reduce the tension on the deck belt and release it from the clutch pulley.
- If you have an impact gun and matching socket, it can be a good PTO clutch removal tool to unbolt the screws.
- Now, before removing the three screw bolts, bring the piston up to TDC contraction stroke. Otherwise, there can be a risk of getting the rope may lash around the valve, and it is not easy to remove.
- Detach the spark plug reverse the position of the piston a little.
- Insert the four and a half recoil rope into a cylinder but leave the head sticking out.
- Slowly remove the bolts spinning them counter-clockwise. Then the piston will then collide with the rope preventing the crank from rotating.
- Then, hold the clutch and gently pull it off from the engine shaft.
After taking it off, you can check the power flow and resistance with a multimeter.
If the clutch displays optimal digits, you may not need to replace the clutch at all. If it doesn’t, then repair it or replace it with a new one. These instructions also apply to how to remove clutch from zero-turn mowers.
