Small Engines (Lawn Mowers, etc.)/homelite mightylite gas trimmer


homelite crankcase
homelite crankcase  
I'm trying to take apart a homelite mightylite 26 trimmer to clean it up and change crankshaft bearings. I am trying to remove the crankshaft, counterweight and piston assembly but since the cylinder is part of the crankcase, I have run into a problem.  I have removed the snap rings on both sides of the crank and it seems to me that the counterweight is pressed onto the crank but I'm not able to get it to move.  Are you familiar with how this assembly should be dismantled?

That model is not designed to be repaired.  You can not remove the piston and you can not buy parts other than the short-block for about $80.

Did you see the dis-assembly videos on You Tube?

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.
