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. Please note
that two tools are recommended if using a micrometer. Shim tool
measures exactly 5mm in total length to make calculations simple. The
bottom flange measures exactly 1mm again to make the math easy. 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 use while we recomment two shim tools if using a micrometer.
The photos below should give a good visual explaination how the tool
works with both a dial caliper and a micrometer on the opening and closing
shims. Call or email sales @ desmoparts dot com if you have any questions
on how to use this tool 800/406-1042.
How to use the tool
Closing Shim Measurement with Dial Caliper
Closing shim shown being measured using a dial caliper
and one tool. Place big end of tool in top of shim. As you can see the
total measurment is 11.85mm. To get the shim measurement subtract the
tool length (5.00mm) from the total. So 11.85 - 5.00 = 6.85. So know
we know this closing shim measures exactly 6.85mm using the dial caliper.
Closing Shim Measurement with Micrometer (two tools
required)
Closing shim shown being measured with two tools and a micrometer. Place
big end of tool in top of shim and small end of other tool in bottom
of shim. In this example subtract the total tool length (5.00mm) and
the bottom of the tool flange length (1.00mm) from the total length
of the assembly. The whole assembly measures 12.85mm. So 12.85 - 5.00
- 1.00 = 6.85. So we know this closing shim measures 6.85mm using the
micrometer.
Opening Shim Measurement with Dial Caliper

Opening shim shown being measured using a dial caliper
and one tool. Insert small end of tool inside opening shim. As you can
see the total measurment is 8.98mm. So 8.98 - 5.00 = 3.98. So we know
that this opening shim measures 3.98mm using a dial caliper.
Opening Shim Measurement with Micrometer (no tool required)
Opening shim measurement with a micrometer does not require a tool.
