57 10hp sportwin magneto coil part#?

[markfromohio]

I just got done rebuilding the carb, new ignition parts and all. I bought a new tourque wrench to put the nut back on for the flywheel, and tourque wrench never clicked while tightening. So I over did it, and broke my cam. I know dumb move. I found one on ebay for a 63 sportwin, is this the same part? I am wondering if i may have also damaged the flywheel. No visable cracks. the carb was also missing the filter, does anyone know where i could get a replacement? I got this motor free with a boat I bought from a buddy, so all I have in it is the money for the parts, but I really like the looks of it and want to keep it. I also wanted to say that this web site is great, so much information. Any advice is welcomed. thanks

Re: 57 10hp sportwin magneto coil part#?

According to my documentation, the part number for a coil is 580197 and you need two. These motors don't have air filters. They're called air silencers.

As far as the other part, I don't know if they will interchange with a 63, but if you wait around, someone who has the documentation will chime in.

'57 and '63 use the same cam, part number 510168.

If you crammed the flywheel down so far that you broke the cam, you probably destroyed (stretched) the tapered hub and will break another cam or will have trouble with shearing the key from now on. That usually is done by somebody that tightened the nut with an air impact wrench. OR----not having the tapers clean and dry before installing the flywheel. Proper torque is 40-45 foot pounds (480-540 inch pounds). I wonder just how much you put on it (?) You didn't lube the tapers, did you? Whatever, the damage is done.

Are you speaking of the sintered filter that goes in the glass bowl on the bottom of the carburetor? You have to get that from an Evinrude dealer.

I've gotten those fuel filters (in the glass bowl) from tim's outboard 218-682-2331. They also have used, tested coils for pretty cheap, and they ship quickly. Have the model number handy when you call..

Re: 57 10hp sportwin magneto coil part#?

thanks guys for all the info. I found the part number last night. I e-mailed the guy on ebay who had the cam i was looking at, and he gave me the part number I was looking for. He said it was 510168 same as F_R so thats what I am going with. In the title I asked for the coil number, but I was really after the magneto cam number. I was just flustered after possibly ruining my flywheel.
1946Zephyr- I am sorry I meant the fuel filter in the glass bowl.
F_R- is there any way to check the tapered hub on the flywheel? because thats what I am afraid of, breaking another cam. As for your question about the torque, I have no idea how much I put on it. The new wrench never clicked and i obviously put too much rear end into it. I am a big guy with plenty of it.
kbait- do I need to find the part number for the fuel filter then? or are they all the same?
If I did spread the tapered hub on my flywheel what do you think the odds are of finding a replacement?
Can the hub be removed and a new one put in the flywheel?
If not whould one of you guys like to buy a sportwin? Just kidding guys.
Thanks for all your help

The filter is part number 303133, the notched nut that holds it is 304539, the gasket for the glass bowl is 303122. The filter element is the same for all as long as it is the type that goes on the bottom of the carburetor.

I don't know of an easy way to check the hub without some sort of a gauge or old crankshaft or something.

Re: 57 10hp sportwin magneto coil part#?

am I correct in thinking that the hub would have split like the cam did? At it's weakest point the notch for the pin?

Re: 57 10hp sportwin magneto coil part#?

Tim's will have the cam too.. And flywheel, but that may not be necessary. Just give 'em the motor model number and they'll get you the correct filter (in the glass bowl). tims: 218-682-2331 If you need the little gasket for that bowl, they'll likely have that too, or hardware store rubber washer trimmed to fit nicely w/sharp razor.. haha..

Good luck!

The hub is made of steel and the cam is made of powdered metal. Steel can be stretched and bent considerably before it tears or breaks. Not so with that sintered metal stuff--it just breaks.

Re: 57 10hp sportwin magneto coil part#?

kbait-Thanks for tim's number. I will give him a call.
F_R- Good point on the steel.
What would you guys do? try another cam, and risk breaking it, or just go ahead and try to get a flywheel? should i get a new pin also while i am at it? I have only spent about 150$ so far on the parts for the engine. Carb kit, coils, tune up kit, impeller kit, lower unit seal kit. And thats all I have in it. So i think this engine is worth sinking a few more bucks in. I cant believe I over torqued it. Live and learn I guess..
thanks guys

Re: 57 10hp sportwin magneto coil part#?

If this is a motor that you plan on keeping and puting to use, It's a good investment. These are good and reliable motors and offer many years of good use.
You could have the flywheel checked over and get a second oppinion on it if you're unsure, but I think if you set it in the correct place with the key, you can tell, if it fits on there correctly. If the center of the flywheel was damaged, I believe the damage at this point would be pretty visable. You could also remove the key and see if the flywheel fits on there snugly. Who knows, maybe the key is incorrect and maybe that is what shatterd the cam.

Re: 57 10hp sportwin magneto coil part#?

I hate to even post this, but I'm worried and curious at the same time.
Do you have any idea what the problem was with the torque wrench? Did you mix up the inch-pounds torque with the foot-lbs. torque, since they're given in both measurements? You're not the first ot have done that.
I'm just worried if the problem was discovered so that it won't happen again. I'd think you might as well try the old flywheel since those cams should be easy to find in case you break another. I'll bet I even have an extra or two.
Just curious, since my torque wrench didn't cost a bundle (yes, it's a cheapo):redface: and it's never given me any trouble with keeping good reliable torque measurements.
Good luck with your motor,
JBJ

no sir this wrench only has ft lbs. and it too was a cheapo from O'reillys. I have done work with the really cheap ones, the ones with the pointer gauge. I bought an upgrade. the kind you set and it clicks. had it set to the torque spec in my owner's manual. I used a nice chain wrench I had for the flywheel, and had that braced against the engine stand for the motor. hand tightened the nut, then put the new wrench on it. tightened and the new wrench just never clicked or did anything to indicate i reached my torque. I kept telling myself well it's about to click it just must be drawing the flywheel down on the shaft. gave it one more good grunt and thought that has to be tight enough. then tried to turn the engine over and it was really hard to do. so i knew i had overtightened. and sure enough. I had broke the cam. the key had swiveled and the top of it was inside the crank. metal shavings on the top of the cam key slot. and i grabbed the cam and pulled up on it and it came back up the shaft maybe a heavy 8th of an inch. hope this helps.
P.S. will use the pointer style torque wrench from now on. lesson learned...

I've been kicking that "what would I do" question around in my mind. After considering several answers that are impractical for somebody without a lot of parts or specialized equipment, what I think I would do is grind about .030" or so off the top or bottom of the new cam and go with it. Might work out ok, worth a shot. I drew that .030" number out of the air, actual circumstances may vary. The flywheel has to push it down far enough that the upper spring retainer doesn't interfere with the points, but not so far that it hits bottom and breaks. Without having the motor in front of me to look at, that's my best thought.

Re: 57 10hp sportwin magneto coil part#?

I'd get the new cam and key and use original flywheel. Tighten it hand tight (just hold the flywheel w/your hand and use wrench on the nut). Then spin clockwise slowly with plugs out and see if anything's binding. If not, wrap a rope around the flywheel and test spark. If all is still well, torque the nut correctly and do the tests over again. Add one fuel filter and off you go, -unless your waiting on the groundhog.. Snowing and ice in Minn..

I think thats what i'll do. I am going to call Tim and get a cam and key and try it. worst thing that can happen is a cam break again. then I will know the flywheel is bad. and then i might try the grinding trick with the next one. or decide to try and find a new flywheel. one way or another I will get this thing going.
P.S. just called Tims and they are checking for the parts, but it is 4:30 there and they leave at 5:00 so she is going to call me back in the morning. They are checking for a cam, fuel filter,key, and asked them to check for flywheel just in case.
One more thought...maybe when i get the new cam i will try putting it on without all ignition parts on so i can look under the flywheel and see the cam. take a measurement down to where it will bottom out, and mark the cam. i might have to use a mirror to see the mark but that might keep me from breaking the cam. torque it in 10 lbs increments. then if it works out take it back off and put ignition parts back in and retorque.

Re: 57 10hp sportwin magneto coil part#?

tims called me back today said they had all the parts. but when i called them back they said that they had a match for one of the three part numbers on the back of the flywheel. he said it was off a 56 and asked if my pull assembly had 1 catch or 3. i told him mine had 1 and he said the motor that the other flywheel came off of had 3. so befor he would send it he has to make sure it will work, which is cool. but i dont understand why the number would match up if it wouldn't work on mine.
i wasn't going to get a flywheel until i was sure this one was bad, but he priced all of the parts at 44$. which is less than what i could get a new cam for at the site i was on befor. so that was a no brainer.
thanks kbait for hooking me up.

No problem. The folks at Tim's have always been awesome to me, and my wallet!
