Getting flywheel nut off (Motor Update!)

Recommended Posts

Right now I'm working on a '73 Johnson SeaHorse 2hp to get it back up and running. This is my first real motor project and so far, it's the flywheel nut that's been giving me the worst problems. Any tips on getting it off? I don't have a flywheel puller but I'll head off to get a harmonic balancer if that's what it takes. Thanks for any tips!

Can't you somehow secure/tie down the flywheel to prevent spinning, then use a 1/2" ratchet and socket to back it off?

I would use a strap wrench (rubber or nylon webbing) and hold the flywheel.

That or a air or electric impact should do the trick.

You may have to do some research or ask a mechanic but I learned the hard way one time working on a chainsaw that the flywheel nut (in that case it was the nut that held the clutch on) was left hand thread! I thought it was just super tight and really reefed on it and ended up stripping it out! Finally realized after that it was a left hand thread. Felt like a dummy afterwards but I guess that's how you learn. Not sure if left hand threads were ever used in this application so hopefully someone could let us know.

Standard thread, use an impact wrench if possible or strap wrench and breaker bar to remove the nut. Harmonic balencer puller works well to pull the flywheel.

Good idea on the strap wrench, I'll look into that. What kinds of stores sell them bigger than 12 inches on the nylon?

I used to push rope into the spark plug hole to stop things from turning.I wouldnt use a impact when using the rope. use this at your own risk RR

I used an old leather belt - worked fine.

Alright, finally got the flywheel and nut off! Was excited to look under, see the coils were bad, replace and have a working motor. Instead we were greeted with below:

Turns out everything has been replaced before (not sure how recent). I wasn't getting spark, so is there a way to test each component out to see if something failed on me? ***The gap was at about .01 on the points, could that have been the problem?

Not being sure on what to do next, we took the powerhead off and inspected the driveshaft.

The underside of the powerhead was caked in oil and grease

Likewise, the housing and driveshaft (not pictured) were covered

The impeller was in perfect condition.

Any ideas on what the next step should be? Thanks again for the replies and looking forward to getting this back up and running!

The condenser could be bad, check for wore spots on the plug wire where it could be sparking to ground or an open in the plug wire. There really isn't much at all to that system.

    • Fishing a mid lake Hump that came up to 45ft. Caught most of the fish between 50-61. We did catch some on the top of the hump in the evening. 
    • How deep were the trout running?  We heard ultra deep on Crow to 30 ft.  The 30 ft number came from people actually catching them.   Thanks for the pics!  I like the fly rod smallie.
    • try the raid spray on grass at bottom. 
    • Here are some pictures from this years trip!
    • How do you keep ants off your feeders, especially hummingbird and oriole feeders? I've tried Toro and Raid sprays on the post but it seeks the birds don't like that smell either and i don't see many for a while. Has anyone else experienced that? Any good ideas?
    • I should’ve looked closer - I have an eyes open pic too. 😌  Tough to tell sometimes on my phone screen.  
    • Among other wilds that have moved into our urban areas, we can now add loons.  There is a breeding pair on the lake formerly known as Calhoun, mostly staying on the west and northwest sides.  But there is also a bunch of yearlings fishing the east side, numbering maybe six or seven and so unafraid that they come right up to the 36th Street dock and try to steal suckers being used for musky bait.  Maybe the call of the wild is not really so alien to the South side of Minneapolis, but it looks like the loons have moved in and can be heard calling from time to time. 
    • Sounds like you guys gave her heck up there to find them. I'd be praying thanks, too if I got that one on! ☺️
    • Quick recap:   Weather was too darn “nice”!  Upper 80’s - 90’s; no wind to speak of; mostly sunny. Water temps were anywhere from 64 - 71 depending on location and day.   We looked the lake over from end to end, marking up our map and returning to some places where we saw fish either later the same day or a couple days later.  We could literally see the transition from spawn to post spawn happening during our stay.  Being new to both muskie fishing and that lake, we spent time in dead water as much as good water but feel like we got a pretty good handle on how to go about setting up a more efficient return visit.  It was a lot work and long hours but I’d go back this weekend if I could so I must’ve enjoyed it.   A few pics as hoped for:
