A-35 Flywheel Removal

[The Boat House]

Much of offering advice is past expense. Knowing what worked is
helpful in making suggestions for others. 9 times out of 10 we
don’t hear the outcome. However maybe Tim tried to show us what
worked. This was his last Post. It didn’t work. Did he try again and
have everything go poof? It can be frustrating.

Hello Tubbs & Joe,

I’ve not given up on removing the flywheel, just stepped back for a bit. I’ll try using the knockout tool again before doing anything else.

As I see it I have tw0 options.

1. Try using the knockout tool and strike it a little harder.  My concern here is damaging the crankshaft. How hard can one strike the tool?  Has anyone ever broke a crankshaft when striking?
2. Cut the flywheel off to avoid any damage to the crankshaft.

My offer stands on anyone wanting to step up and give it a smack!

Advice, comments welcome.

Thanks

Still hanging in there Joe, just took a break to think about the next move.

Responding to your concern as to how hard one can strike the tool
without breaking the crank shaft – at least this hard. This is the same
crankshaft that is in your motor.

Thanks Tubbs,

I’ll give it another go.

I believe it will separate after a few really good whacks. If not I
suspect your going to find something out of the ordinary that’s
keeping it from separating, possibly making both the crankshaft
and flywheel unusable. Its more likely that it just on there tighter
than normal, but what ever the case, I suggest you use this method
to its maximum potential before moving on to more drastic measures.

Tubbs,

I viewed the youtube video showing striking force.

I’ve struck the removal tool equally as hard as in the video, I may give it another go.

Thanks again.

I’m in this same boat with this same motor. Tried heat and tapping. Will try the 8″ puller (currently in the mail).

I’ve read in a couple different article not to use a puller.

I tried a puller but didn’t crank it down much in concern of bending the flywheel.

Let me know how that works for you.

Post a picture if available.

If your flywheel is really stuck you can pull the
center down and completely through the
flywheel, if you decided to keep going, using a
3 jaw puller pulling from the outer edge .
Watch my video.
You must make this tool.
If you don’t have a welder you can just jam the
2 nuts together. How hard you need to hit the
tool and how many times is determined by how
tight the flywheel is on there. Just tapping on it
won’t separate them. You must hold the flywheel
up at the top of the crankshafts end play.
If it doesn’t pop loose right away stop and check
the tool to be sure it remains tight.
