This manual provides -operating instructions, ser­ vice information, and repair parts lists, for Model C-10, C-lOHD, and c..:12 crawler-mounted hydraulic excavators. fuformation in this· manual is applicable to all models unless otherwise noted

MACHINERY PLATFORM

• The machinery platform (see figure 1) is fully reinforced at stress points to provide a rigid base for operating components. The location of compo­ nents on the platform results in a well balanced rotating unit, and provides easy access for servicing aff parts including hydraulic lines and connections.
• The use of a three section tandem hydraulic pump, results  in the elimination of gear drives and thus increases efficiency. This  also provides each control valve with  an independent oil supply for top response under all operating conditions.
• The hydraulic reservoir · is equipped with three separate suction . hoses and three separate return hoses. The three return hoses are each equipped with a safety-flow oil filter with cleanable filtering

An .automatic “house brake II safety feature elimin­ates all drift and creep,  even in the event of engine failure. The house brake· is automatically actuated by  spring force when the operator- releases_ the swing lever or for any other reason that catises a lack of . pressure to the swing circuit. When the swing circuit is in use, the house brake is a1,1tomatically released by hydraulic pressure.

BOOM, DIPSTICK, AND BUCKET

The boom is made of high strength steel and is of extremely. ·deep box section. Bpomflge strength is- further increased by the addition of an internal plate, and extra large reinforcing ·plates at the top, bottom, and sides which extend’ beyond the area of greatest stress concentration.

The dipstick is made of high strength is internally reinforced.

The bucket is also reinforced at all high points. The  bucket teeth  are pin connected and are individually replaceable.

All pivot points of the dipstick and  bucket linkage elements·.

Disposable filtering elements are · also

are equipped with steel. bushings and heat treated

available. Each filter has a back-pressure gage to indicate filtering effectiveness. If a  filter element becomes clogged, the automatic by-pass valve in the filter will open to allow the oil to circulate.

SWING BEARING

The double row ball bearing swing bearing results in greater effectiveness, reduced maintenance, smoother rotation, and the elimination of such parts as king pins, rollers, roller paths, buhings, brackets, nuts, thrust washers, shims, etc. This greatly increased effective­ ness is a result of the swing bearing’s ability to ab­ sorb all axial, radial, and tilting forces; and to distrib­ute them over a much wider area than is possible with conventional rollers. The swing bearing is bolted to­gether to form a completely enclosed unit which elim­inates adjustments and day-to-day maintenance other than lubrication.

Since the swing bearing is the only connection be­ tween the carbody and the machinery platform it eliminates any rocking motion except that permitted by the carbody as it moves over the terrain. pivot pins to minimize we.ar.

CRAWLER UNDERBODY

The crawler underbody is equipped with split­ chain sprockets, self cleaning tread and tumblers, and centrally located lubrication points on the side frames. The fully enclosed track adjustment elimin­ates “freezing”. Double-flange track rollers provide maximum bearing surface in wear areas. Heavy ship-channel side frames, extra heavy shoes, and involute splined power shafting, are proof of its rugged, job-proven construction.

CAB AND CONTROLS

The cab provides excellent visibility and protection from the elements. The large front glass panel can easily be removed. All control lever linkage is above the machinery platform and away from mud and dirt. Controls are conveniently located and swing and boom levers can be interchanged for right or left hand operation if desired. The bucket and dipstick controls can be hand or foot operated (see figure 1).
