FOREWORD_________________________________________ This manual contains illustrated parts lists to help you select quality Ditch Witch® replacement parts for your Ditch Witch equipment. Using other replacement parts will lessen the productivity of your equipment.

•

Descriptions and specifications in this book were current at publication.

However, the Charles Machine Works, Inc. reserves the right to improve equipment, so this manual might not reflect the most current improvements.

•

Part numbers enclosed in a box or marked as “obsolete” in the remarks column are no longer available from The Charles Machine Works, Inc. Your local Ditch Witch dealer may be able to locate the part for you.

•

Footnotes provide more information to help you identify parts shown in the manual.

•

Assembly instructions referenced in footnotes are available through your local Ditch Witch dealer.

•

Instructions on recommended equipment use and maintenance are in the Operator’s Manual that was shipped with your equipment.

Keep the following in mind when ordering Ditch Witch replacement parts: ♦ Specify parts you need by part number and description, not by illustration

reference numbers.

♦ Have equipment model and serial number on hand to help ensure you get the

right parts for your machine whether it’s old or new.

Torque Information Tightening Guidelines Values given on the following pages are a guide. Do not use these values if a different torque value or tightening procedure is given for specific application. Check tightness of fasteners periodically.

Shear bolts are designed to fail under predetermined loads. Always replace shear bolts with identical property class fasteners.

Fasteners should be replaced with the same or higher property class. If higher property class fasteners are used, tighten only to torque value of original fastener.

Make sure fastener threads are clean and that the threads are properly started. This will prevent them from cross threading or galling when tightened.

Lubed means cleaned, dry bolts lubricated with a standard, medium-viscosity machine oil. Lubricate all contact areas of the bolts and washers. Lubricating the bolts is the suggested torque method.
