About the Shim Tool
A precision tool made from grade 316 stainless steel. Use this tool as an aid to measure Ducati opening and closing valve shims on your next Ducati valve adjustment. Our shim tool is universal and is used equally well on both the opening and closing shims. In addition it also works with both dial caliper and micrometer instruments. Shim tool measures exactly 5mm in total length to make calculations simple. Tool is manufactured with a small hole through center to allow for perfectly flat precision surfaces that are parallel to one another. The hole also aids in safe storage of the tool. Our shim tool is not magnetic so it won't collect dirt.

Our custom designed shim tool is designed to work whether you're using a dial caliper or micrometer. Just one shim tool is required for dial caliper or micrometer use. Photo instructions below. As you can see the 4v tool use is much easier than 2v use. Call or email sales @ desmoparts dot com if you have any questions on tool usage 800/406-1042.
