hey all, i just bought an older argo yr (80) 8 wheel with 16hp tecumseh engine ,just wondering if anyone would know how you remove primary clutch from it , i have removed cluthches before with no issues but those had the threaded bolt that went all way thru to crank , this one has bolt that is only about 2and half inches long and lets clutch come apart , but back side of clutch remains on crank , any suggestions would be greatly apprecated , thanks in advance
