Bush Hog CBH80 - Manual (Page 18)

TOOTH REPLACEMENT
The bucket tooth points are shelf-sharpening and will
require little attention; however these points on the
bucket shanks can be replaced when they become
badly worn or broken. If a tooth shank breaks off,
becomes damaged or lost so that it cannot hold a
tooth point, a new shank should be welded to the
bucket in its place.
Peened-On tooth points can be removed from the
welded tooth shank by hammering at “A” (Figure 5)
on the tooth point or by driving a chisel at “B”, just
between the tooth point box section and the tooth
shank. Install the new point and anchor it to the
shank by peening at the location shown.
Bolt-On tooth points, when worn, can be replaced by
removing the hardware that connects it to the cutting
edge. Install new tooth and replace hardware if nec-
essary. (Figure 6)
Roll-Pinned tooth points, when worn, can be replaced
by driving out the roll pin with a hammer and punch.
Install the new tooth using a new roll pin and hammer.
(Figure 7)
Economical and efficient operation of the backhoe is
dependent upon regular and proper lubrication of all
moving parts with a quality lubricant.
All parts provided with grease fittings should be lubricat-
ed with a good quality chassis lube type grease. If any
grease fittings are missing, replace them immediately.
Clean all fittings thoroughly before using grease gun.
Lubricate all grease fittings at least twice daily, once
at the beginning of operation and again approximate-
ly halfway through the work day.
Lower stabilizers to the ground and lower boom so
bucket rests on the ground as shown in Figures 8.
Refer to these illustrations for the location of all
grease fittings.
IMPORTANT: Before greasing boom to swing
frame pivot (*) shown in Figures 8, raise boom and
install transport lock pin shown in Figure 1.
On Models CBH60, CBH70, CBH80 the following
locations should be oiled with SAE30 oil:
A. All Control Handle Linkages
B. Seat Bracket Pivot Figure 7

LUBRICATION
IMPORTANT: Avoid excessive greasing. Dirt collects
on exposed grease and increases wear greatly. After
greasing, wipe off excessive grease from fittings.

Periodically, check to be sure all bolts and nuts are
tight. See torque chart, page 51 .
Check all pivot pins for cotter pins, washers and
retainers; if missing, replace.
