need a TC Setup for a 16hp 1 1/8 shaft

[TKmech21]

I ordered a 44c from MFG and they sent me an email back saying they didnt have any in stock, they were on backorder and they did not know when they would be able to get any more from their supplier. If Comet is no longer in business is there any other manufacturers or options? The 44 series was going to be a lot to spend in a setup, Not looking forward to have to jump to a 94 series. I found a 94 driver on ebay for 240 and a used driven for 250. What would you do? another option would be a custom clutch, but i was hoping to use a TC setup.

Ebay usually has some Comet 40s or 44s. I would try there.

 

[TKmech21]

I checked. the only one I can use would be a 44c, or 94c. again i have an 1 1/8 shaft. There are some 94c's available, and I guess if thats all I can find I will have to shell out the extra money for it.

It might be cheaper to get that shaft machined down to 1" and grab a regular 40 series.

Comet is back in production. They are in Janesville WI. The 94c is an awesome clutch. That's what run on my odyssey. May be overkill for a 16hp engine. You could get a 94c and ise a secondary off a snowmobile to save some money there.

Would they be compatible for belt width/angle/RPM? And how would you figure out belt length?

The snowmobile stuff would. You won't get the rpm from the 16hp. Not sure if that can be modified. I don't understand the question on belt length. Is that important. I thought u would go by whatever belt you used.

 

[Doc Sprocket]

Oh, it certainly would matter! You know that CVT belt tension is critical to proper operation. Therefore, altering a sheave diameter or center spacing would alter the required belt length.

 

[TKmech21]

That would be awsome. I looked up snowmobile secondarys on ebay, there are a whole lot to choose from and cheap too. If that would work i would definately explore that option. So you run a snowmobile secondary on your Odyssey? Or just the 94c?

Couldn't you locate the secondary for 1 belt size and reuse that same size of belt? The 94c is an aftermarket for snowmobiles I believe. Not positive though.

I run the stock odyssey secondary. The comet 90d would be the proper replacement secondary. Let's discuss more before purchasing anything. I'm not positive it will work.

We need to talk more about clutch spacing(like primary to secondary. Is that important? If so I Sid not know that. Just know you buy the 94c for the odyssey and forget about it. Works with the stock secondary. It was made specifically for the fl350 though.

Sorry guys. I got out of hand with repeat postings.

My setup will be all custom as far as spacing center to center. So i'm guessing if i knew what the spacing should be I could just make it work. I havent come up with an idea for a jackshaft or anything yet. My project is to the point i have the engine mountable on the swing arm and all my clearences are good to go. Now I need to focus on the drive system.

Fatcat, do you know what the shaft diameter is on an fl250? I found this kit that looks like a great deal if it would work. I know the driven would work its a 90d the driver is what i have in question. Anyone know if mfg would put together a "special" kit for you to come close to the cost of this one? http://www.mfgsupply.com/snowmobile/snowclutch/snowcomet/snowcomet94c/209187a.html

If I could get an 1 1/8 94c driver and a 90d with a belt for around 400 that would be nice. Individually it would be almost 600. The kohler I am using is a 16 horse, listed like 588cc in the kohler manual.

I put a feeler up on the other board. I'll let you know as soon as someone answers. Bighead would be the guy to ask if he's not still fighting fires. He has restored several FL250's. I've never got to play with one personally. $600 is pretty steep for go kart clutches. It would be bulletproof but I would go another route at that price. Maybe get the crank turned down to 1" and use a 40 series. Toystory had a point about RPM's. I didn't think of that. I'm spinning my odyssey at 8000rpm where your engine is probably governed at 3600. Mine doesn't engage until 4200. Not sure if it will work. I don't want to give you bad info. I'll ask a few of the guys on the other forum what they think. Lots of those guys have been playing with clutching for 20 years. I'm pretty green on the subject. I think I can give you better advice from one of them.

You could instal a solid drive sprocket on your engine, and run a chain back to a 3/4" (or 1")-diamiter jackshaft, then use 40-series torqe converter components, with the driven mounted to a secondary jackshaft...

Your first jackshaft could be built similar to this pic, but simply have the 40-series driver instead of a centrifugal clutch:

He would need a lot of room in the back though...alignment may be an issue.

Ok I see, your thinking to get away without having to get an 1 1/8 driver use that type setup. That is another option. I'm thinking the 94c with a sled secondary is going to be the route to go. All I will have to make sure of it the center to center spacing. I do want to use the backing plate idea like in the picture though. Has anyone made a backing plate like that? if so how did you build the driven shaft, as far as bearings etc.?

Good point. Although the T/C driven pulley could be located up above the driver, to save space.
This type of jackshaft plate could also be installed pointing up, down or even forward too...

Yep

Cool, I just thought you might wanna save some $$$ using 40-series components...

I've never built a setup like this, I just found that pic on a Google Image search. That GTG jackshaft plate should fit most any industrial engine, although It might not hold up to the stress of 16hp...
