Gears/Pulley/Belt

We have a 13 hp Honda GX390cc

We bought a 5.5 gpm 3500 psi (actual will be close to 24-2600 psi)

Our questions: What size gear for the pump?
What size for engine?
What size belt?

Thanks,
Monique

Thank you but we want to go with belt not box.

You need to look up the rpm of the engine and the pump. Then there are online calculators that will help you figure out the sizes. Alternatively you can call an industry supplier and they can set you up no problem.

Perfect.

Thank you!
