The AR pump model XTV3G22 actually comes in two different shaft sizes, 5/8" and 3/4". If you have the 3/4" shaft version then yes this pump will definitely work with your current set up. If you have the 5/8" shaft version then no this pump will not work for your machine. The mounting holes will be the same with all of the pumps mentioned
You should definitely verify the shaft size on the engine you currently have before making the purchase.
