Clinton Gear Reduction ?

[AMC RULES 36,945]

Finally made some time today to tinker around with this 2.5 hp Clinton I picked up recently.

Tank and carb looked so clean, I figured if it had good spark I'd try putting fire in the hole and see what happens. As it turned out...good spark is an understatement. If your not careful this little guy will light your fire...don't bother asking me how I learned this.    

Once filled with oil, a splash of gas, it fired off on the second pull...seems like a pretty strong runner too.

So...my question is concerning the gear reduction unit attached to the crank...anyone know what these units were originally used on?

Also, how does it come off...there only two external bolts I see holding it to the block...but I'm thinking it must be fastened to the crank somehow too?  

An idea on what to expect before I tear into it would be greatly appreciated.

I've never seen one before, but to me it looks like its just a little gear on the crank driving a big gear for the PTO.

 

I'm guessing you just split that PTO housing, remove the gears, and then remove the rear of the PTO housing.

 

Hows that for a wild shot in the dark?

[squonk 38,962]

Let me guess. Your wife was holding the plug wire and you pulled the cord ?????

I think Kiwi is right, at least that's how they are on the Kohler gear reductions.

I HAD ONE ON 3 1/2 HP TECHY MOTOR. I REMOVED IT AND THE CRANKSHAFT WAS ONLY  1 1/2" LONG IT MADE IT A LITTLE SHORT FOR MOST APPLICATIONS.  THE MOTOR WAS ON 1968 GAS POWERED LAWN ROLLER. HOPE THIS HELPS

I'm with Mike and wallfish, Craig..... Take the PTO housing off and see what's in there   ... I've never one of those either.

Let me guess. Your wife was holding the plug wire and you pulled the cord ?????

 Nope...it was running while I took it. 

[AMC RULES 36,945]

So...if is does turn out to be a short shaft...

any way to extend it...adaptor available or fabbed up? 

[Howie 882]

There are two more bolts inside that cover if it is like briggs. The end of crankshaft will have splines or teeth

cut on it to mesh with bigger one in there to get the 6 to 1 reduction. The cranks I have seen could not be used

for anything else.

OH...that figures...it runs great.    

[buckrancher 2,675]

craig put the model and spec. numbers up looks to be a clinton  gem  engine i can come up with the right crankshaft number for you

Wonder if Charlie (clintonnut) would know anything about these engines. He may have seen some along the way, might be worth shooting a PM his way.

[buckrancher 2,675]

looks like you need a model #21100 or #46-353 crankshaft to replace the short crank of the gear reduction unit

 

this is a 100-2000 thru 190-2000 GEM clinton series engine the 160-2107 engine was a 6.1 gear reduction motor

standard crankshaft for a 100-2000 series should interchange

Just PM'd Charlie...hopefully he can help too. 

Thanks again Brian.    

It would be a shame not to be able to use this motor, it runs so good...

can't have seen much use.  

Another question...what are the correct numbers found on an original   Clinton?    

[clintonnut 126]

There is a drum gear inside that reduction box that the crank drives. It is a 6:1 reduction unit commonly used on rototillers.

If you remove it, you will find that the crank has gear teeth cut into it, making it nearly useless for anything else without swapping the crank.

OK Charlie. 

     

[buckrancher 2,675]

Another question...what are the correct numbers found on an original   Clinton?    

1200-152

1200-184

1200-2184

B1290-1107

So...these numbers would be the correct model #'s Brian...

like the 160 2107 stamped on the plate above?    

[buckrancher 2,675]

yes

[AMC RULES 36,945]

You're the best Brian...thanks again.
