GENERAL INFORMATION
Digging chains can be modified to dig trenches in a variety of widths. By modifying an
existing chain, it can be used to dig the width you want and thus save going the expense of a whole
new digging chain assembly. This can be a considerable cost savings, however it is more work
than just installing a new digging chain assembly.
The information given below is a complete listing of all the possible chain width conversions
for 2.00" pitch chain for your trencher. Included in the listing is a break down of all the parts
(including part numbers and quantities) needed to make the conversion. Simply install the new
parts (and rearrange the old parts) so that the finished chain construction follows that described
in the “Digging Tooth Station Sequence” chart and the “Digging Tooth Station Break Down”
diagrams for 2.00" pitch chain (located elsewhere in this section).
It should be noted that this information only applies to modifying chains of the same length
and pitch. All components must be of the same pitch. You cannot intermix components of different
pitch.
