Paragraphs 335-340
ALLIS-CHALMERS
ing the number of shims (4) ani
should require no further attention.
Always reinstall same shims as were
removed.
335. DRAWBAR LINK ROD. Length
of link rod (5—Fig. AC181) should be
such that it will just fit over connect-
ing pin when the drawbar is free in
the forward position and draft regu-
lating lockout screw (A—Fig. AC164)
is turned into housing. Too long a link
rod will decrease the draft, and if rod
is too short it may break the control
linkage.
336. HAND CONTROL ROD.
To ad-
just the link rod which connects the
lever on steering column to the lever
on pump, first loosen the set screw at
upper end of rod. Place hand lever at
top of quadrant and push control lever
on pump down. Tighten the set screw.
MECHANICAL LIFT
Models RC-WC
340.
To disassemble the power lift,
remove the unit from the tractor. Re-
move pin (18—Fig. AC182) from
worm gear (2) and drive power lift
shaft (15) out far enough to remove
pin (5) from ratchet (6). The need
and procedure for further disassembly
will be determined by an inspection
of the parts and by reference to Fig.
AC182.
When reinstalling unit on trac-
tor, vary number of gaskets between
housing and torque tube to provide a
slight amount of gear backlash and
install sufficient shims (12) between
housing and frame to assure correct
alignment.
