INSTALLATION
Numbers in parentheses refer to Fig. 1.
Note: Tighten all fasteners to standard torques listed
in Section 300-0080, STANDARD BOLT AND NUT
TORQUE SPECIFICATIONS.
Note: The plow bolts used to attach the scraper
cutting edges and side blades must be tightened
correctly if the blades are to stay in place. The plow
bolts have square shoulders which fit into square
holes in the blades to keep the bolts from turning. If
the bolt shoulders are not seated properly the bolts
cannot be tightened adequately and the blades will
eventually work loose. To make sure the bolts are
torqued to the recommended 750 - 820 Nm
(550 - 600 lbf ft), strike the heads with a suitable
hammer while tightening the nuts with a torque
wrench. When the torque on the nuts cannot be
reduced below 750 Nm (550 lbf ft) by additional
striking on bolts heads, the bolts are then properly
seated and tightened correctly.
1. Inspect cutting edges (7) for damage and replace if
necessary. Position cutting edges (7) to blade base (3)
and secure with plow bolts (1) and nuts (2).
2. Inspect side blades (5) for damage and replace if
necessary. Position side blades (5) to bowl frame and
secure with plow bolts (4) and nuts (6).
3. Place the battery master switch in the 'On' position
and remove blocks from all road wheels.
BLADE ARRANGEMENTS
Numbers in parentheses refer to Fig. 2.
The scraper cutting edges (blades) and scraper blade
base are designed so that one type of edge can be
used for various edge arrangements. In addition, the
edges are reversible which prolongs the useful life of
the edges. The use of the proper edge arrangement
for certain types of cut or soil conditions can save a
great deal of money in edge replacement and labour.
Scraper edges should never be allowed to wear to the
point where the blade base is doing the cutting.
The 100 mm (4 in) drop centre arrangement is
recommended for hard, rock-free soils when a
maximum drop centre and centre heaped loads is
required. To renew this arrangement after one edge is
worn, reverse all edges and interchange the outer pair
of edges (1 & 4) with the inner pair (2 & 3).
The straight edge arrangement is recommended
whenever a level cut or a level fill is required. To
renew this arrangement after one edge is worn,
reverse all edges and interchange the outer pair of
edges (1 & 4) with the inner pair (2 & 3).
The maximum overhang arrangement is
recommended for fast, easy loading in rock-free soils
and for maximum edge wear life. When working in
rocky soils, the minimum overhang edge arrangement
is recommended. For beginning scraper cuts on side
slopes or to crown a scraper cut, the one side cutting
edge is recommended. These three edge
arrangements cannot be renewed by reversing the
edge when one edge is worn, however, the edges can
be used with the 100 mm (4 in) drop centre and
straight edge arrangements.
SPECIAL TOOLS
