straight through 1" clutches

[Magice]

I was wondering if theres such thing as a 1" clutch that slides right down the shaft like most 3/4" ones do.. If so does anyone have any cheapy links?

 

[Russ2251]

Like this?

 

[Magice]

yes

 

[Russ2251]

Cool. This is only clutch I could find that suited my 'special needs'.
Unfortunately it is not cheap. $129 is cheapest I could find.

good lord... I need a 1" clutch for my 13.5hp subaru but the only one I could find is for a #35 chain like the one in that picture, I need one for a size 40 chain as the subaru's 22 ft/lb of torque would snap the little chain with the slightest blip of the throttle.
Wish I could afford a comet 40-series torq-a-verter.

$$ for me is not the problem. I just don't know if TAV can be setup to operate 'as advertised' with my somewhat less than traditional power plant.
I'd hate to buy this thing only to find out it cannot be adapted.

If you buy good chain like REGINA gold 35 chain you will NOT break it. Its 8 bucks a foot though. I use it on my junior dragster which will run 7.30's@95 MPH. Plus the side of the chain is a shiny gold colour which looks good.http://www.hench.net/images/080203/DSCF0007.JPG

Problem is, this is not a straight through bore as Mr. Magice and I require.
This clutch uses a bolt to shaft scenario using a 5/16x24 bolt and is also not bi-directional.
The only clutch that is usable on Lawn-Boy shaft is what I pictured in above post. Noram part #160157.

7th clutch down on this web page:

I just bought a second one as a backup (or twins?).

 

[Magice]

Oh snap.

That would be perfect except the engine is an 11hp.

I've thought of hacksawing the crank before but could never bring myself to it.

 

[Russ2251]

May be no choice here. TAV is probably the way to go.

You need a crankshaft with a threaded hole in the end to hold on the drive pulley, that or use a jack shaft setup.

It isnt that hard to just drill a hole and tap it...ive done it..

Gotta be perfectly straight, preferably done on a mill. You only get one shot.

 

[crazycart]

Well ive done it, just gotta know what your doing and be careful.

 

[Russ2251]

Unfortunately I don't have a conventional crankshaft along with some possible clearance issues, but appreciate the pointers.

Hey Russ,

Just researching Noram #160157. I found this chart on Noram's website. There are a couple other clutches, #160151 (for #35 chain) or #160153 (for #40-41 chain) that uses needle bearings instead of a bushing AND has a smaller tooth count. Are either of these a possibility?

 

[Fast Eddie]

Oops. Now I see why. They're about twice as much $$.
