Anyone know if there is a direct mount pump that will work on a tapered shaft?
Your cat pump is the same one I had on a smaller PW I have hooked to a gx160. The problem is the unloader and downstream injector are built into the cat pump. My unloader went bad so I had to replace the whole pump. Not sure what size engine you have but I replaced mine with a Udor PNL 3gpm 2k psi direct drive pump for $300 from Sprayer Depot. I put my own unloader and chemicel injector on it and it runs much better than the CAT pump. The cat pump will probably be about $360-380 so you’re better off with the Udor or even a General Pump. If you have a gx200 or gx270 you could get a larger pump.
I have the Honda GX200 engine.
Check around for a shaft adapter
I’m looking at getting a big 30hp with the tapered shaft. Looks like maybe split sheave pulley may work, depends on taper. Otherwise, ive seen where the engine is mounted to lathe, turned on and recut, maybe go smaller taper size then get adapter. I likely will not go the straight shaft swap.
