l have a 1969 55hp Chrysler outboard motor. The only puller l can get on it is a gear puller.It grips the teeth on the flywheel very well.But I am afraid to tighten too much.Is there anything else holding the flywheel besides the nut on the crank?Anyor other comments would be appreciated.Thanks

usually there are threaded holes (3) in the flywheel that you would screw studs into that are connected to the puller. Pulling by the teeth is not a good idea.

If you pull it by the teeth, you will break it for sure.

No, the shaft is tapered & there is slot with a keyway in it to lock the flywheel to the shaft when it is spinning. You have the wrong puller. You need one with bolts that thread into the screw holes on top of the flywheel. Tighten the puller a bit & tap very lightly all around the flywheel with a hammer to break it loose. Do not hit it hard or u will crack it.

Added note 8/4/08: Richard C. is correct. I've been boating since 1948 & owned a 70hp back in the 1960's. l should have remembered about the Chrysler flywheel not having the standard threaded holes for the puller.

Actually, Chrysler used a wedge bar that you put under the flywheel and a ''nut driver'' basicly a threaded bar that you hit with a hammer, screwed on the crank shaft. There are not any holes for a flywheel puller. I' not sure where you can get one, but you can get the job done by improvising. weld two or three flywheel nuts together for the ''driver'' and any tapered bar stock will work as the wedge. l guess the other answerer is do not go back that far????

Mark t & Josh r correct - u need to use three bolts screwed into the flywheel using ur puller a harmonic balancer puller works well, the screws r usually 1/4x20 be sure to use a washer under the head of the bolt & grade 5 bolts will be better than standard bolts also spray some penitrating oil around the shaft (nut) then apply pressure u will need to use a strap to secure the flywheel to keep it from turning an old belt will work place strap in opposite direction of the way u will apply pressure on the tool to remove flywheel. This is to keep the flywheel from turning the same direction as u remove flywheel. If it is stubborn then tap lightly on the flywheel or top of remover puller.

Richard C is correct. The chrysler had a wedge hammer technique. Best was a really big hammer tapping very lightly. Make sure the wedge did not tilt the flywheel. Only supported it so the low frequency tapping of the big hammer would ''shake'' it off. Line up the key way with the wedge and add penatreting oil. If you pull by the gear all you will have is some of the gear on the floor.
