Harbor freight puller work on 3hp Yachtwin flywheel?

[LargemouthBass21]

I can’t get the flywheel off of my motor with the hammer and screwdriver method and I believe it’s time to invest in a puller. Being the cheapskate i am, I found a ‘Bolt-Type Wheel Puller Set’ on the Harbor freight website for about 14 bucks. I will attach a link, will the puller work on my 1964 Yachtwin 3hp?https://m.harborfreight.com/bolt-ty...yjfD_BwE&utm_referrer=https://www.google.com/

That’s what I use everyday. Get three 1/4x20 grade 8 bolts/washers, and you’ll be pulling some flywheels!

I'm big on HF tools for one-off, or DIY nonprofessional jobs. If your flywheel has two or three evenly spaced threaded pulling holes, this will work as well as anything you can rent. And at a lower cost, plus you get to keep the tool.

The kit's puller bolts may not match your flywheel's threads, but grade 8 bolts are cheap and available at a good hardware store. Lube the center jack screw, and hold the puller frame with a wrench while cranking. If the flywheel is stubborn, douse the shaft with panther pee 'Liquid Wrench' type penetrant. If that doesn't work heat it up with a propane soldering torch.

I do not believe you will ever need to use a torch on a 3 hp flywheel.----And all these motors from 1950 on with the universal magneto had 3 holes for the puller bolts.----Some motor even had a captured nut on the flywheel that pulled the flywheel with no special tools !

Thanks, will do. I have a 20% off coupon as well so an even better deal!

Spot on advice. They work fine but the bolts and washers are junk.

Thank you, I’m glad this will work
Just clarifying, is 1/4x20 the correct size for my 3hp Yachtwin?

I have heard the included bolts do not work with my flywheel anyway. I will be getting some grade 8s at the hardware store.

Just make sure whatever size bolts you get for your engine, they are grade 8, or forget it. I've broken lesser bolts doing the same task. But grade 8's worked perfect. Also, thread them in pretty far but not through the flywheel where that can hit whatever is under neath. JMHO

About how much would 3 grade 8 bolts run me? I have a lot of different kinds of washers already so I dont need those. Do I need nuts too?

3 grade 8 bolts - no nuts. Bolts thread right into the flywheel. Can't be more than a couple bucks.

AutoZone will loan you a puller for a $20 deposit.

On a 3 hp I have used just any 1/4-NC bolts.----Even head bolts from a 6 HP will do.-------These things are not that hard to pull off !!

My H.F. yoke broke the first time I used it but that was on a 1968 Johnson 100HP V4 flywheel. Also, the pressure screw's threads buggered in that same attempt. Good luck and let us know what happens!

Fortunately. mine is only a 3hp. Hopefully, I can get it off easier.

I bought the HF puller. As others have said, keep the plate & jackscrew, pitch the useless bolts. That said, it was still a struggle because you have to strap the flywheel to keep it stationary.

I finally surrendered and bought the OMC puller kit, and in retrospect, I should have done it years ago. You can say "it's just a puller", but it just works so much easier. And the sidebar offers something to "pull against in opposition".

IMO: just buy the right tool. This isn't the only time you'll need to pull your flywheel, and having the right tool is worth it. Buy quality, and you only cry once. HF puller, you'll cry every time you reach for it.

My $.02; use or discard as you see fit.

My way of seeing it is I only have one outboard and I won’t have to pull the flywheel very much. It’s only a 3hp so should come off fairly easy. But if I get another boat project I would certainly consider an OEM OMC part
