From here all you will need to do is select the correct engine bushing. Most pumps are 24mm shafts. Engines are either 1′ or 1-1/8″. If you are not sure about the shaft size of the pump you can Google the manufacturer, model number and include the phrase ‘PDF’ in the search stream, you should be able to find it.
Example ‘General TS2021 PDF’ will bring up exactly what you need. Engines are a different story. Typically engines between 13 & 19 HP have 1″ shafts and larger engines will have 1-1/8″ shafts. It is easy to find out which one you have by simply taking a ruler and measuring the shaft diameter.
