Small Engines (Lawn Mowers, etc.)/weed eaterbrand-push mower


ive replace the blade adapter 3 times and it keeps braking
and freely turning around the shaft.i think the shaft is messed
up,can those be replace on them. and if so how do you remove them.i have try to look it but can find how to do it.

thanks scott

If the crankshaft is messed up you could replace it.  Replacing the crank takes a lot of time and very special tools to torque the rod and installing a new oil seal.

You could have a machine shop repair the shaft...expensive.

You could weld the blade adapter but you would never be able to remove the blade adapter.  

Have you taken the mower to a small engine repair shop and asked them to look at the shaft and see if it is messed up?  

You could also have a machine shop look at it...they will be able to tell if the shaft is damaged.

Depending on the problem, you may be able to drill through the blade adapter and shaft and install a bolt and nut all the way through the hole to hold the adapter to the crankshaft.

If you attach a picture I may be able to tell you if the shaft is bad.

Try attaching a picture.

Born and raised in the midwest. Started tinkering with engines when I was about 14 on my Suzuki RM-80. I began lawn mower repair at a small hardware store. I knew absolutely nothing. I read lots of repair manuals and met an older fellow who taught me many lessons. I continued working on small engines through high school and paid my way through college working on mowers at the same hardware store. Decided to get away from the midwest and mower repair so I joined the Air Force. I repaired air traffic control electronic equipment and ended up in Hawaii where I got a part time job at Small Engine Clinic. I gained a lot of experience from the Small Engine Clinic and had a blast repairing small engines. I then took the Briggs and Stratton Master Service Technician test and earned my MST. I then traveled to Wisconsin where I attended the factory update training seminar and received formal training. Continued working on mowers part time as I completed 20 years of military. Retired from the military on a Friday and continued in the lawn and garden industry the next Monday.
