Open a Parts Diagram to Find a Part Number
Look up your tool by Catalog (Cat) # on the tool nameplate. There are two serial number formats:
1. Three numbers and a letter (653A). Click on the corresponding link.
2. Three numbers and a string of numbers (653-10245). Each parts diagram covers one product revision starting with the listed serial number and continuing through higher serial numbers until the next listed revision. Click on the link for the serial number that is closest to yours but still smaller.
