Lawn boy 10685 approx. 15 years old. Grinding from self propelled gearing on rear axle. Check YouTube on removing and replacing the gears.
Came apart ok but unable to remove drive pin holding gear to rear axle. Disassemble rear further and put axle on the vise. No luck. Liquid wrench, let soak overnight, buy new set of punches. No luck. I counted 50 blows with a 2 lb mini sledge hammer and punch....would not budge. This assembly has lived in grease it's entire life...never dry.
Counted 100 blows with a small ball peen hammer and punch. No good. Finally hit it with the ball peen and no punch and could drive it flush but no further using any combination of punches and hammers. You could see the liquid wrench "sink" around the pin but it simply would not budge. Gave up and put it on the bench grinder and ground it and the gear down about 1/8 inch. Ground so slick you could hardly see the pin. More liquid wrench, punch, and hammer.....nothing.....
I don't think I learned anything......just a disappointing experience..🦨🦨
