Ive had this engine lying around for quite some time. I know its a 433 and I kinda remember the sled it came out of. It was a 70's sled with the hydraulic drive system in it. My dad plowed it into a stump in the late 70's and it sat for a while. Then he stripped off a bunch of parts and scrapped the frame. All thats left is the exhaust, speedo, handlebars and the engine. I'm just wondering what sleds this motor came in, seeing as I may be looking at getting rid of them. Heres some pictures of the engine.

Also, this engine is a runner, did a comp. check and has about 120psi both sides.

I am not positive, but I think 74 or 75 either the TL or TW sled. I think those were the only Y433 hydraulics.
 
Help identifying a ss433

Hi, I don't mean to jack this thread, and I know it is several years old, but I am new and cannot make new posts yet. I am trying to identify an SS433 sled motor that I recently bought. Here is the info on the motor:

Number on shroud is SS433-003230
2 into 1 exhaust
2 into 1 intake with single Keihin carb
Has reeds in intake
Two individual coils
Was told it came off of a Polaris sled (but don't know if it was stock motor)

I don't know what other information you would need, but if there is something else, please let me know and I'll try to come up with it.

Thanks for any help in advance in identifying this motor!!
 
Sounds like a 1977 exciter case numbers are ss433.was the only reed engine of the exciter years to come with a keihen carb round slide.exciter has everything else you described.also 1977 was the first year for the reeds 1976 exciters had piston port.I have several of these sleds including the 1977 1978 1979 1980 they are all pretty much the same some differences in body so I think you got a 1977 engine and also is the motor fan cooled it should be if it's an ss433 engine .
 
Thanks for the great info! I really appreciate it!! And yes, I forgot to mention that the motor is fan cooled off the flywheel fan and has the shroud wrapped up around the heads to direct the air over them.

So, I am assuming that this motor has a cdi rather than points if it's a '77 exciter? I was thinking I read that somewhere in my searching to find what it was, but maybe you can confirm or deny this.

I don't suppose anyone knows where I can get a wiring diagram for this motor? It's got most of the harness, but none of the switches or controls, so I'm not sure what goes where.

And what about the fuel pump? It has two vacuum lines going to it (one from each cylinder), one line going to the carb, and what I believe is the inlet from the fuel tank. But there is a bigger hose just beside the fuel pump that I do not know what goes to this port. This port is not actually made into the pump itself but seems to have it's own housing made into the block just beside the pump. Does anyone know what goes here and what the actual hose set up for the fuel pump is supposed to be so that I get everything hooked up correctly?

Sorry for so many questions, but sled motors are not really my area, and these are quite a bit different than the ATV motors I'm used to working on.

Thanks for any further replies though!!
 
The wiring is really pretty simple what kind of sled are you putting the motor in.you have your engine wires just match up the colors.and as far as controls there is a cluster of wires on main harness and if you have the controls beam switch kill switch all those have ends and can only plug into the right spot.I might have a diagram I'll check.
 
Well, that's where the problem is. I'm not putting it in a sled. I'm putting it in an '80 FL250 Odyssey. So I don't have anything to match the wires up with. Really, it should simplify the wiring since I won't be using most of it, except for the main ignition and maybe the lighting wiring. But the main thing is getting it to fire and figuring out the fuel pump. So, any help with those two things would be tremendously helpful.

I do have one other question, from everything I keep seeing on the web, the '77 has a single coil with dual wires coming out. But this motor has two individual coils, one for each plug. Is this correct for a '77 Exciter?

Thanks again!

Do you have the cdi box.just plug it in .plug coil in harness grounds to engine fire it up the wires are all color coded .
 
After looking at the harness again, it does have a small box, which I'm assuming is the cdi box, that has 12v printed on it. This box has one single green wire coming out of it and that is connected to the harness that is not hooked up to the motor. So, I would also assume that as long as this harness plugs into the motor wires, it should be hooked up correctly once the cdi box is mounted to ground it?

But what about having two coils instead of a single coil with two plug wires? Could someone have changed it over to dual coils instead of a uni coil? As long as it works, it really makes no difference to me, but that part is still confusing me a little.

And do you know what lines are supposed to go where on the fuel pump? Or what goes to the bigger hose fitting that is bolted between the fuel pump and and the end of the block on the clutch end? I still don't know what was supposed to go there or if it something it needs. I thought maybe oil injection or something. I don't know if this motor even had oil injection, which it probably did, but I will be mixing the oil/gas and running that way. Too easy to trash a motor if the oil injection quits without warning. But if you would know how to hook up the lines on the fuel pump, that would help a lot.

I really do appreciate you taking the time to help me out with this motor. I know I'm kind of committing a sacrilege by putting a sled motor on an ody, but the sled motors are a lot more reliable than stock ody motors and a lot cheaper to find parts for. So, thanks again!!
 
Actually looks like the box I was thinking was the cdi box, is the voltage regulator. At least that's what it looks like on the parts breakdown I just found. So, maybe I don't have the Cdi box, which I'm assuming is going to be a problem if I don't? Just wanted to clear that up.
 
Ok on the fuel pump it should have 3 nipples.they usually hve direction arrow on them .you got a fuel into the pump. There is a fuel out of pump to carb.and the big line from crankcase is the pulse line to run the pump.as for oil injection.the pump is located on bottom left of motor back of the clutch.just plug it of and make sure the 2 oil lines on bottom of intake just back of the reed cages are block off so no air can run threw the lines can cause alot of tunning problems and engine damage.hope everything works out and I was a help to you.
 
So the two lines running from under each intake are the oil lines and not the actual vacuum lines for the pump? It has both of those lines still hooked up between the intakes and the pump. The big fitting just behind the pump has nothing on it, but that is the pulse port and needs to be hooked up to the fuel pump then? Sorry if I'm not following this correctly. I'm trying to visualize what it has as I sit here, so it might make more sense when I look at it again. But do I need to unhook the two lines between the pump and the bottoms of both intakes then, since I'm not running the oil injection? And hook up the large fitting to the pump? Hopefully that is correct. Starting to wonder if I'm looking at the oil injection pump instead of the fuel pump now. Is the fuel pump a large round mikuni style pump? If so, I don't have that on this motor, but I do have a spare laying around that I can use.

And I'm starting to wonder if I'm just missing the Cdi or if maybe this motor has points for some reason. I don't see anywhere on the harness where the cdi might have been, but I may be overlooking something. I don't know if this tells you anything, but there are eight wires coming out of the motor just behind the shroud. One bundle has five wires and the other one has three wires. Does that sound right for a '77 Exciter?

And you have been a tremendous help!! I really appreciate everything you've posted. Thank you so much!!!

The pulse line comes right out of the engine block it will hook to your fuel pump.the reason you want to block off the oil lines from oil pump to intakes would be cause the intake can suck air cause there isn't any oil there any more if the pump isn't in use.Just plug off all oil pump lines.or just remove the pump.ok the wiring start by plugging in the coils them wires have a cloth braiding on them and when they get dirty it's hard to tell the color just pull the loom back so you can see the color everything will match up if you have the right harness.every exciter I have seen has a single dual coil butt the singles coils you have may plug in.The cdi will plug in to the wires coming out of the mag
 
I think it's starting to make sense to me now. Is the pulse line right back by the oil injection cable? If so, I think I know how to route those now. Finding the pulse line for the fuel pump was the main concern. I'll just block off all the oil lines as you suggest since I won't be running it.

As for the wiring, it looks like someone has spliced some aftermarket connectors onto the coils, so I'm starting to think they replaced the single coil with those older dual coils. I guess the first thing I need to do is find a Cdi, if possible and go from there. All of the harness connections appear to be stock and not cut or spliced, so if I get the right cdi, it should just simply plug in and go. I hope anyway!!

Thanks for all the great information! You really have cleared a lot of this confusion up for me tonight and it is appreciated very, very much!!! Thank you again!! ;)!
 
That little box u have is the cdi just double check to make sure your motor doesn't have points cause they didn't use a cdi box before you go buying parts ok well let me know how you make out
 
Ok, it was bugging me so I went out and took another look at the motor. Here's what I saw.

No boxes on the harnes except for the little flat silver box that says 12v on it and it is about 2 inches square by about 1/2 inch thick with two mounting tabs on each side of it. Still looks like the voltage regulator from the pics I have been looking at on the web though.

The big fitting I was thinking of on the very back of the motor looks like it was probably a tach or speedo. Definitely isn't a hose fitting because it is threaded.

I found the main pulse line which was right in the side of the block about 3/4 of the way forward from the clutch end. No fuel pump to be found though, but I have a mikuni pulse pump I can use, so that's no problem.

Now the oil pump is still confusing. It has two lines going into the bottom of each intake runner that attach on each side of the oil pump. One line with a pancake filter in it that was hooked to the carb. And another port that has nothing hooked to it. I'm assuming the empty port would have to be the inlet from the oil tank?

The carb has the big black plastic fuel line inlet fitting. The connection from the oil pump. And it has another port with nothing on it right next to the air cleaner rim. Not really sure what went here. Can I just block off both of the extra two ports on the carb except for the main fuel inlet since I'm running pre-mixed fuel or does it need the one near the air cleaner flange hooked to something? Would make things a lot simpler if it just had the fuel inlet though.

And lastly, the coils definitely have been spliced with aftermarket blade plugs, but I couldn't tell where they had them plugged into the harness yet. I'll check that out though.

So, I hope this helps explain what I'm working with. If I had a decent camera I'd take some pics, but I think the only real problem I'm seeing is the missing cdi box if it doesn't have points. I'll have to pull the shroud and see what's under there before I know that for sure.

If any of this doesn't sound right, please let me know. Thanks again for all the useful information!!
 
Ok on the carb that fitting on top bY the air cleaner rim leave it as it is and don't block it that's the way it's supose to be. As far as fuel lines all u need to make it run is fuel pump and pulse line that's it. eliminate all that other garbage but just be sure to block those lines going to the intake.
