scratchy mower clutch
My riding mower is more than 10 years old. I've had it a year. Today,
I replaced the back idler pulley on the deck: bad bearings. After installing the belt, I pulled to to see if the belt and the 4 pulleys worked freely. Pulling it forward, it was quiet, although there was more resistance than I expected. Pulling it backward caused a scratchy noise in the electric clutch. With the belt off, the clutch pulley was hard to turn and made a scratching noise in either direction. In spite of all that drag, it doesn't move the belt when the motor is running and the clutch is switched off. If there's a scratching noise, it's not loud enough to hear above the motor. I read on the internet that clutch plates can get rusty, and the cure is to start the motor and switch the clutch on and off several times. I tried that. It's still scratchy. I wonder if the bearings are dry and dirty. As they're used only when the motor is running and the blade clutch is disengaged, they might last a long time this way. Has anyone else encountered a scratchy blade clutch? I wonder if the solution is the pop the clutch off ( one 10x1.5x60mm cap screw ) and flush the bearings with lubricant. What would be a good lubricant for this? |

As the piston comes up the rope will stop the piston. Be sure to leave about 6 inches of rope sticking out of the hole so you can pull it all back out once you are done. --- This email has been checked for viruses by Avast antivirus software. http://www.avast.com |

That's much better than my scheme, fill the cylinder with oil and screw the plug back in. It dawned on me to see what happened when I turned the crankshaft with a wrench. The pulley didn't move. Blade brake! Because nobody here told me there was such a thing as an electric clutch with a blade brake, I'm expecting a substantial award from the Alt.home.repair Complaint Compensation Fund. I only wish it had been in time for Black Friday. |
