During changeover, stroke changes with the new system are accomplished in three easy steps: The crank-throw bolts and locating shoulder bolt are removed; an adjustment screw allows the crank throw to travel in the gibs to the desired stroke setting; and then the crank-throw bolts and locating shoulder bolt are reinserted.
These innovations include full safety guards that provide easy accessibility for maintenance and tool changeover, side-loading capabilities, EZ-adjust crank throws, fine-adjust platen parallelism, drop-away release connecting rods, treadle lift, canopy retraction, and automated controls for tool positioning.
Its sideshaft runs on the center of the crankshaft (most are next to a flywheel), the belt pulley is also in the center of its crankshaft, and the crank throw and rod are on the outer end of the crankshaft opposite the flywheel.
The 3/4" X 17-1/2" drive axle shaft utilizes a 3/16" X 1-1/2" X 5" flat metal crank throw (a 2-1/2" washer, welded in place 1" from that bar, makes a good walk stop).
