Another inquiring mind question

[krazy_horse 59]

I read on our frrum (somewhere) that big block Kohler starters would interchange between 10,12,14 and 16 horse engines but I saw one with 10 teeth and another with 13.Surley this will not interchange? or can you interchange the drives? I did try to search this. Thanks for any responce on this.

Just a guess but could one of those be a hi-torque starter?

Mike, I wrote the man I bought the starter from and he said" yes they will interchange and one would turn the engine over faster "but did not say which one,the 10 or 13 tooth would do it. I wanted to be sure before I installed as not to dammage the flywheel. Regards

I belive it would be the 10 tooth one that would turn it over faster. I think the 13 tooth one was for the 16hp. Those are harder to turn over because of the compression. Dont remember right now and my books are at work so i cant look it up. Hopefully someone will correct me if i'm wrong

Both starters are interchangeable. The 13 tooth will turn the engine over faster. I have a 13 tooth starter on one of my B-100's.

I've used both on all the engines they fit fine, infact all the Case tractors I have torn apart ALL had the 13 fine tooth drive, maybe because they turn the hyd pump that is bolted to the engine as it is starting.

think of it this way

say your flywheel has 130 teeth

a 10 tooth starter will need to rotate 13 times to turn the flywheel one revolution

a 13 tooth starter will need to rotate only 10 times to complete one revolution of the same flywheel

the closer the driver gear size approaches the driven gear size - the closer the driven gear speed approaches the drive gear's speed.
