The first step to a successful order is finding the proper information for part identification. This information should be located on the engine or machine, usually on a tag.

You should always consult your owner’s manual for specific information about your equipment.

To make ordering easier, please have the following information available:  

  • Equipment 
  •  Manufacturer
  • Technical Specifications:
    • Engines - Model, Type and Code Number (Some engines also have a Spec Number)
    • All Mowers - Model and Serial Number 
    • 2 or 4 cycle Equipment - Model and Serial Number


Each bearing has an inside diameter, outside diameter, and width diameter, in that order. Most bearings are metric in size, but can also be imperial. 


  • Measure your blade's length diagonally from cutting tip to cutting tip.
  • For mulching blades, use the back side of the blade for ease of measurement.
  • Measure the width at the widest part of the blade.
  • Measure the center hole.
  • Measure the center to center distance between the outer holes.


To identify the proper carburetor, examine the side of the carburetor to locate the carburetor number. The carburetor number is usually two letters followed by two or three numbers (i.e.: WA-80).


Remove your old clutch and find the manufacturer's part number located on the back of the clutch.
