INTRODUCTION General •

•

MANITOU DOLRM reserves the� right to make changes or improvements in the� design machine or construction of any part of the� without incurring the obligation to� install such changes on any previously deliv-ered machines.

This parts manual should not be used as a technical data reference; it uses simplified illustrations and does not detail servicing procedures.

Parts Ordering Information •

•

•

When ordering service parts, specify the correct part number, full description and quantity required, as well as the respective machine and engine model and serial numbers. For your safety and continued proper operation, use only genuine service parts.

“Right”, “left”, “front” and “back” are determined from a position sitting on the operator’s seat and facing forward, and the excavator “house” rotated so that the blade is also facing forward.

Some illustrations will contain circled letters or a circled combination of letters and numbers in addition to the regular number callouts.

These special callouts may be used to identify hydraulic port locations which are marked on components, or to identify the two ends of a hose, tube, or other part that is shown split in the illustration. They may also be used to indicate a common reference point when different versions of components are shown on the illustration.

Serial Number Locations and Information Locations The machine serial number is located on a metal plate at the inside of the left rear tower.

The engine serial number is located on the engine valve cover, and also on an additional sticker at the inside of the right rear tower, inside the engine compartment.

Additional Serial Number Information

Torque Charts Standard attaching hardware torque values are provided on the inside back cover, and some torque values may be shown in illustrations. Metric torque values are shown in Newton-meters, and are converted to foot-pounds by multiplying by 0.738.

Parts changes are often defined by serial numbers, and less often by date codes.

•

•

Illustrations and Parts Lists •

•

•

•

Not all parts shown in the illustrations may be included in the parts listings; some are not serviced separately or are not included on engines sold in all areas.

Ref. Nos. shown in the parts listings without part numbers are shown for reference purposes only and are not available for purchase.

Boxes or brackets may be used in some illustrations to indicate assemblies (part groupings), or in some cases to highlight different versions of individual parts or assemblies.

Text references may be present on some illustrations to provide additional information.

•

•

Serial numbers as shown in the parts manual may have prefixes M (machine) or E (engine) preceding the serial number shown on the identification tag.

(From 1st SN) – indicates that the part can be used on all machines from 1st serial number to present.

“XXXXX” and “ZZZZZ” are used in the SN sequence instead of numbers for parts that have changed, but where the serial number for the change is not known.

In some cases, a date code is used instead of a serial number, and is displayed in the YYYY.MM format. Months will be displayed as .01-.12. For example, 2012.02 would be the second month (February) of 2012.

INTRODUCTION Reference Number Sequencing in Parts Lists

Unless otherwise specified, all cap screws, nuts, and bolts are Grade 8.8, cadmium or zinc plated.

NOTE:

NOTE: The following abbreviations may be

Reference numbers in the illustrations and parts listings may include sequencing variations of hyphens (-) and/or letters.

FOR EXAMPLE (Ref. Nos.): 5 = Original version/configuration of a part or assembly 5-1, 5-2, etc. = The hyphen (-) indicates an updated version/configuration of Ref. No. 5, and should have an associated serial number. The highest numbered version is the latest. If a hyphenated version is shown in the parts listing, but only the nonhyphenated version is shown in the illustration, the versions are visually similar. Multiple versions may be shown in the illustration, to identify changes.

5A, 5B, etc. = These parts do not replace Ref. Nos. 5 or 5-1, they are added components and may have an associated serial number.

5-1A, 5-1B, etc. = These are added components and may have an associated serial number.

NOTE:

There may be a Ref. No. 5A without an associated Ref. No. 5 in the list. In that example, Ref. No. 5A is a newly added part and may have an associated serial number and also an additional note or remark.
