so the question is ; what pulley ratio do I use? would it be 1:1?  the motor is a Kohler K532 19.9 hp on my LGT 195 assuming full throttle 3600 rpm? ( is that correct rpm?) and the pump is the stock unit on a johnson model 12. I need to clean to see if there is any #'s on it . presently pump has 6" pulley so 6" on motor ? smaller or larger?

how many variables are there? any and all comments would be appreciated

Thanks Tom

Tom, I have not been on for a while, so I ptolly missed afew things in your query. What are you looking to drive via hydraulics?

 

Yes, 3600 RPM would be correct.

 

Best to get those numbers on your pump up here on the board so people can have a shot at making a resonable answer.

 

Either way, good luck :-)

You should be able to look up the numbers on the pump and find out all the specs. If you post them someone may have the specs to post.

The most important thing is clockwise or counter clockwise.

Start by running the pump 1-1 IF you need a little more speed you could run it up to maybe 4000rpm for the pump ,at max throttle (3600rpm engine)

  That pump looks to be about 6gpm , that should work nice for  your application.

it came with the loader so it should be adequate . so 1:1 is where I'll start Thanks   and yes Joe that is the next thing ,orientation in tractor so it spins correctly with motor.  if anybody can point me to a supplier of pulleys that would be helpful, I will be bolting it in between the bracket off flywheel and shaft to hydro unit.

Thanks Tom

Tom,
I don't think that's the pulley You want. Your paying big bucks for the quick detachable hub! The hub will cost you extra. What's your shaft dia? Do you have a key way? What's your belt width?
The last pulley I bought was off Ebay, $10 plus shipping!

Joe,

Thing i like about that  pulley is the bolt pattern for mounting . I don't need a removable hub, just looking at that style hoping to find something similar but hopefully cheaper. Tom

There is definitely an equally strong, cheaper and simpler way.

I buy the hub I want, with the bore size I need from Princess Auto, (sorry it's Canadian) and then a weldable sprocket or pulley to match. Its not changeable, but its solid and cheap.

it usually 15 bucks or so for the combo depending on size.

Maybe Harbour freight or some other place can do it for you. Possible McMaster carr, or ?

graingers prices are insane for the average joe. If you have a corporate account, then you can get better deals.
