    587 PTO removal

    I am trying to replace the crank seals in a 587 white motor. I assume the PTO un screws from the crank. Does it turn like a regular bolt and nut lefty loosy righty tighty? LOL I put some pretty good torque to it and it didnt loosen a bit

    Yes it unthreads like a regular bolt. CCW when looking at the damper from the rear of the boat.

    Put a rope in the PTO cylinder to lock the crank. Then take a pick pipe wrench and unthread the damper.

    I wouldn't hammer on it, I would be afraid of twisting the crank out of phase.

    I have the top end off already and I have a tool that goes into the splines hooked a 1/2 inch breaker bar on it and still wont loosen. Is a little heat a bad idea anything else to try

    I don't know what to say.. heat is fine if you are replacing the crank seals. The problem is that you have to hold back the crank from turning. Might be quicker to reassemble the pto cylinder and stick some rope into it to jam it.

    I once took off a coupler by holding the crank in a vise, but the crank was going to be rebuild, so I wasn't worried about it slipping out of phase.

    I just removed my PTO by holding the crank in a vise. The PTO came off easy. I bought the crank used and I needed to replace the seal and o-ring behind the PTO.

    I got it man what a pain it came off really hard. I put the plate back on put the whole thing in a vise with a piece of wood against the crank inside the case to hold the crank still. Then a 6 foot pipe and 1/2 inch breaker bar.
