Lehman little dipper

[tomas4fifty8]

I inherited a Little Dipper skid steer, the engine is needing work so I swapped it with another one from a parts little dipper that can with it. Same engines but the coupler is different. So the burning question is how do remove the couplers from one engine to another?

Never seen a Little Dipper up close, but i assume the coupler is on the crank shaft? Is it on with a Browning coupler/ with their wedge system, i kind of new Fritz Lahman,,i am sure he used the basic stuff when building his machinery!!!!
