Flywheel removal

[*EdC*]

Guys
What is the best acceptable method for holding the flywheel in place while trying to remove the flywheel's center nut? Also is this a right handed nut?

Thanks, Ed

Ed, it's right hand and we have a automotive flywheel holder but most people use a large screwdriver against the starter shaft.

Re: Flywheel removal

Just finished putting mine back on. I used a 6 foot piece of rope tied to a box wrench. Knotted the other end of the rope and put the knot into one of the vent slots of the flywheel. wrapped the rope around the flywheel (like a strap wrench) and torqued the flywheel nut back on.

BE SURE TO USE A FLYWHEEL REMOVAL TOOL. USING A PULLER THAT ATTACHES TO THE OUTSIDE OF THE FLYWHEEL AND PUSHES ON THE TOP OF THE CRANKSHAFT WILL DAMAGE THE FLYWHEEL MAGNETS!

80 BUCKS FOR THE PULLER IS CHEAPER THAN 200 FOR A USED FLYWHEEL (400 FOR A NEW ONE.

Good Luck!

Re: Flywheel removal

I just borrowed a flywheel puller from my local shop (didn't even know the guy and I let him hold my steering wheel puller till I brought his puller back........swweeeettttt!) But I do believe my harmonic balancer puller would have pulled it off, because it wasn't stuck that much and I didnt have a clue how the flywheel was made till I got it off. Anyhow, I used a impact wrench to get the nut off, don't have a clue how im going to get it torqued back on yet. No, Im not going to use the impact to put the nut back on....hehehe

Re: Flywheel removal

Ed, To get the flywheel locked for torque, I used a ratchet strap, wrapped it around the outer edge of the flywheel and cinched it down to the rear engine handle, then torqued flywheel nut. Worked like a champ. Good Luck!

Re: Flywheel removal

I pulled my flywheel off last week. used an 18" pipe wrench to hold the flywheel in place.
I used the non-recommended gear puller to remove the flywheel. I took the slack out of it then put 50 lb's pressure on the center bolt with a torque wrench then gave the center bolt a good wack with a 2 lb hammer; popped right off!

Re: Flywheel removal

Depending on the hp. On my smaller engines, less than 10 hp, I just hold the flywheel and get an old ratchet with the correct socket and wack it a few times with a hammer. A few wacks and the nut is loose. To remove the flywheel, again I wack it a few times with a hammer and it popps off. You can also use an impact gun to loosen the nut and then use a puller to remove the flywheel.

Have a great day.

Re: Flywheel removal

You guys wack on my crankshaft with a hammer, I'll wack you. What do you think that does to the main bearings, or for that matter the integrity of the crank?

If you use the right tools, you can leave the bfh in the drawer where it belongs, or use it for breaking bricks.

hope it helps

Re: Flywheel removal

It does not take a BFH to remove a flywheel from a small outboard. I do have a puller, but using a small ball pein is easier. But you are right, using a puller is better and really the right way to do it.

Have a great day,

Rob.

Re: Flywheel removal

Whacking the crank and or flywheel to remove a flywheel is sure taking alot on risk on damaging an engine. I have worked on alot of everything in my life, and alot of times not knowing the correct procedure to do a particullar job. With that said, I have SCREWED UP something when I didnt have to (as have some of all of us have here). My Dad used to always say: "If the factory hadn't thought this screw wasn't supposed to be in here, IT WOULDNT BE IN HERE!" And I also have learned: "If the factory wouldn't have said to do it this way, IT WOULDN'T BE DONE THIS WAY!" So come on here guys, lets face it, YOU NEED MORE THAN A HAMMER, A SCREWDRIVER & A PAIR OF PLIERS TO MAINTAIN AN OUTBOARD ENGINE! Just say if I got lucky with a 2 lb ballpeen, dont mean the next guy would. Could damage an engine in costs more than it is worth.

Always good to have a picture...
