TOOTH REPLACEMENT
The bucket tooth points are shelf-sharpening and w ill
require lit tle a ttention; h owever thes e po ints o n the
bucket shanks can be replaced when they				become
badly worn or	broken. If a t ooth sh ank breaks				off,
becomes d amaged or l ost so that it can not hol d a
tooth po int, a new		shank should be	welded to the
bucket in its place.

welded tooth shank by hamm ering at “A” (Figure 5)
on t he tooth	point or by dri ving a chisel at “B”,				just
between the to oth p oint b ox section			and	the tooth
shank. I nstall the new point and anchor				it to the
shank by peening at the location shown.
Bolt-Ontooth points, when worn, can be replaced by
removing the hardware that connects it to the cutting
edge. Install new tooth and replace har dware if nec-
essary. (Figure 6)
Roll-Pinnedtooth points, when worn, can be replaced
