Easy Lawn Mower Repair
Great experience. Website had an exploded view of my lawn mower so it was easy to find and order the parts. Parts arrived earlier than estimated. The parts I ordered were a exact copy of the old ones so everything fitted correctly.

Easy repair. Part fit as expected
The blade adapter on my TroyBilt push mower with Honda engine had the inside key broken out of the wall. Apparently from hitting something. I sourced a new blade locally (old one was worn out) but could not find the adapter anywhere. I measured the engine shaft to be sure it was 25mm and it was. Ordered the new adapter from eReplacementparts using the p/n from the TroyBilt parts diagram for my mower. Installed new blade, new adapter and used the old bolt and bell piece. Did not have a torque wrench so just tightened the bolt as tight as it would go. Back in business.

Turn the mower over. Remove the old part and replace with the new using a 3/4 " socket. Couldn't be easier.

1. Remove spark plug wire

3. Turn mower on its side
4. Use an appropriate wrench to remove the bolt, the blade, and the blade adapter. Be sure to wear leather gloves when handling the mower blade.
5. Replace the blade adapter, the blade, and the bolt. BE SURE TO TIGHTEN THE BOLT SO THE BLADE DOES NOT COME OFF! You may need to wedge a piece of wood between the blade and the mower deck to keep the blade from rotating while tightening the bolt.

First I removed the blade bolt and the blade support then the blade. I had to tap the blade adapter with a mallet to remove it from the shaft. I then cleaned the shaft up. Lined up the key inside of the new adapter to the key slot on the engine shaft and tapped it on with the mallet. I placed the blade on the adapter then the blade support and tightened it all up with the blade bolt.

Drilled out broken screw, and used an easy out to remove it. Removed the blade adapter by tapping on it. I then install the new one by lining up the key inside of it with the key slot on the engine shaft. And I tapped it on. I then attached the blade to the adapter with blade support. And the blade bolt and tightened it into the shaft. Works great now.
