

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.

Free labor will be provided at any authorized Ditch Witch dealership for installation of parts under this warranty during the first year following “initial commercial” use of the serial numbered Ditch Witch equipment on which it is installed. The customer is responsible for transporting their equipment to an authorized Ditch Witch dealership for all warranty work.

EXCLUSIONS FROM PRODUCT WARRANTY All incidental or consequential damages.

Do not use these values if a different torque value or tightening procedure is given for specific application.

Torque values listed are for general use only. 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, these should only be tightened to strength of original.

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

Tighten plastic insert or crimped type steel locknuts to approximately 50% of dry torque indicated on chart.

Apply torque to the nut - not the bolt head. Tighten toothed or serrated type locknuts to full torque value.

LUBRICATED means coated with lubricant. DRY means plain or zinc plated without any type of lubricant.

As a general rule: •

1/2-inch bolts are used in cylinders with 1-inch rods

•

5/8-inch bolts are used in cylinders with 1 1/4-inch rods

•

3/4-inch bolts are used in cylinders with 1 1/2-inch rods

•

7/8-inch bolts are used in cylinders with 1 3/4-inch rods

•

1-inch bolts are used in cylinders with 2-inch rods (one with 1 3/4-inch)

•

1-1/8-inch bolts are used in cylinders with 2-1/4-inch rods

IMPORTANT: Do not reuse cylinder piston bolts when rebuilding a hydraulic cylinder. Each cylinder repair kit contains a new bolt. Use it. Lubricate lightly and torque to value shown on chart.

Thread size indicates the diameter of the threaded area in fractions of an inch and number of threads per inch.

NA = not a current CMW part numbered o-ring, or dash size does not occur in current CMW applications SAE = straight thread fitting that seals by sandwiching a hard o-ring between a shoulder on the male part and an angular surface at the mouth of the female port.

ORS = o-ring face seal; a type of fitting that seals by compressing a hard, captive o-ring between two flat parallel faces, one grooved for the o-ring and the other plain to act as the sealing surface
