Default homelite flywheel

Im almost done with my first conversion but I have run into a problem. I cant get the clutch pins out of the fly wheel. I have been banging away on them for days now and they just wont come out . Does anyone have any advice?



Thanks Tim

Drill the back out first then use a punch to knock then out.

Thats what I did. I even used a sludge hammer to bang them out.

I've removed the pins from four flywheels and they all came out by driving them from the rear with a normal size ball peen but they were in there tight.

Good luck

What are you using under the flywheel when you are hammering on the pins? I've done two engines, the first one I laid the flywheel on a block of wood, & beat on it til I was blue in the face - then I took it to work & laid it on an anvil - the pins drove out with just a couple of blows. The second one I took to work & used the anvil first off, & the pins drove out quite easily on that one as well. Apparently, the wood was cushioning the hammer blows, reducing their effect. Just a thought, hope it helps.

I think your method is best, the idea of just bashing them doesn't appeal to me at all, and it probably isn't good for the magnets either.
Another possibility, - they could be turned down, or milled flush with the surface.

One more way that I have done it is to drill from the back first and then put it in my vise and (sort of press them out ) this works also. I don"t really like using a hammer on something that at high rpm could come apart and cause personal injury to someone!

Talk to Peter Faith at www.wackerengines.com - He'll either sell you one all ready to go, or you can send him yours & he will fix it up. He's a great guy to deal with - both my Homie 25's have Wackerengine prop adapters & mufflers.

Are you sure you the punch is centered on the pin???? What type of punch are you using? Drift or a pointed type? You may have enlarged the end of the pin you have been banging on. Punching them out is the easy method, what follows is only slightly more involved and possibly more rewarding than opening your wallet to get the same product.

Don't let this thing get you down! Let's sneak up on it from the hind side! [>:]. If your pins are like the ones on my flywheels, the heads have bull's eye rings on it. Take a center punch and indent center, insert pilot 1/8" bit in press, secure flywheel, do both all the way , insert 13/64" bit and drill those hummers on thru. You'll loose the head and free the starter lug very quickly finish on thru the pilot hole will help(I like slow speed and some coolant to save the bits a little longer) DONE. (if you right on center you may see the spine marks in the bore.

Same procedure would work from back it you are sure of center. Really no biggy if your off abit the amount of alum wt lost will be minimal.

Post back when your finished. Gone but lurking.......

I think you misunderstood what I said, I didn't mean that they were screwed in, - I meant that you could machine them down flush with the aluminium, using a lathe (turning), or milling them down using a milling machine.
The part of the pin still left in the flywheel would be ok remaining there.

If you haven't got access to these machines, you could possibly hacksaw the pins off, and file them flush.

The other method is, (I do think Mike's idea would work too), drilling from the back, - however, if you're drilling from the back, use a drill a little smaller dia. than that of the pin, and just drill in as far as necessary (ie the depth of the aluminium), don't drill right through the pin. This will leave a thin wall steel tube in the al. with a solid core to hit with the punch and will then be easy to drive out.
As Mike says, use a pilot drill first, and try to get it central.

Bashing flywheels I don't like, unless the pins come out first or second thump.

You guys are a big help Thanks. I think I might try cutting them off. I would try what Mike and willdo said but I dont have a drill press. But I do have a dremmel hopefully that will take them off.

Thanks Tim

I do not know exactly what you are trying to do.....but it sounds like if you use a new hacksaw blade held in a pair of vise grips, you could cut the pins off flush. Then touch up with a file or dremel. ???? hope that helps, Capt,n
