gears for saw head drive system

[larrydown60]

This what I have a 2008 chevy cobalt power steering 12 volt system I am wondering if I use an 11 tooth sprocket on steering pump and 2  17 tooth idler sprockets underneath with the chain  going from one to the other end Connected with to a circuit board to control the speed forward and reverse does this sound right or look right? All the help I can get will be great thanks a head of time

  

  

  

 

the last picture is the way I want do my gears just not sure if the tooth count will be right

 I don't think those steering sectors turn all the way around, just so far in both directions.  Try looking at Surplus Center.  Steve

ladylake this a friend of mines set up he has it working and has cut a log 10' long 48" wide with it but he can't remember the gear count he said he just bought the smallest ones he could find. I looked on SC and these were the smallest gears I could find thanks for your help

go with what your friend used. It will be variable speed anyway.

The sprocket on the motor shaft is the only one that matters.  Smaller will give you lower speed and more force, larger will give you more speed and less force.
Starting with the smallest available is a good plan if you don't have data on motor torque and force needed to move your saw-head.
If it does not work, that would mean the motor does not have enough power.
If it works but is not fast enough, you can put a larger sprocket on the motor (no need to change the idler sprockets).

Watch when you use that motor that it does not get hot.
The motor isn't designed to handle extremely high power for extended
periods of time.
