Chain drive starter???

Have a starter on a small VERY-VERY tired 5 hp briggs motor on a snowblower. A chain runs from the starters 1" toothed gear? to the crankshafts 5-6"? toothed gear-not sure of size.
The chain is smaller than a bicycle chain.
Maybe 1/2 the size.
The big gear will rotate in a reverse direction- then when you move it in the direction to start, it will catch and turn the motor over. I can take off the big gear, Would like to find out how to remove the piece still on the crank shaft. Am not seeing set screws or roll pins/spring pins. Is it a press on fit?
I have no idea on how to remove it.
Need to move every thing to another motor.
Any and all info appreciated. Snow is definately coming!

Re: Chain drive starter???

I'm sure someone on the board can help you. Pictures would be a big help. I have never seen a chain drive starter on a Briggs. I can't help with how to get it apart. As for the chain size there are two sizes smaller than bicycle chain #35 with is 3/8" pitch center to center of the links would be 3/8". Then #25 chain, but I have only seen it on copy machines.

Re: Chain drive starter???

A chain drive starter would solve my belt stretching issues on my suburban!

If I understand what you're describing... its acting like a recoil starter on a pushmower... On those, I just put string in the combustion chamber to stop the piston from moving and grab the base with a BIG pipe wrench and start hitting with a rubber hammer. Eventually it unscrews.

Re: Chain drive starter???

These are not that uncommon.

They use a one way bearing on a race that is coupled to the crankshaft. No idear how this one mounts.

Gravely used them for decades.

Hi T.J. Very interesting. I'm going to throw my $0.02 in here. Clean the shaft right at the edge of the gear. I think you might find a round ring there. Think of the the end of the Briggs starter. I think that is what you will find. Keep us updated!!

Re: Chain drive starter???

I REALLY REALLY appreciate the quick replies. Pictures will have to wait till

My crew is moving over to Cedar Rapids,Iowa tomorrow. (r.r. crew).
Will have my daughter help with uploading pictures.
Kids know a lot more about that than this soon to be (2yrs.) maybe retired old man.
As I said, I appreciate every reply.

Re: Chain drive starter???

I had an "ESKA" Snowblower with a 5 HP Tecumseh on it that had a similar chain drive starter to the one you described--the chain was just slightly larger than your average necklace!...had a one ay sprag needle bearing on the crankshaft that only allowed the starter to crank the engine and not let the engine keep spinning the chain or starter once it fires up..

Mine was held onto the crankshaft by a roll pin,they drilled a 1/8" hole right thru the crankshaft!..I'm surprised it didn't weaken it and cause it to snap off where it was drilled!..I saved all the peices off it "somewhere"...mine was a 110V starter..
