CAB MOUNTING
Cab is three-point mounted with two pivot-type mount­
ings at front and twin cushion-type mountings at rear.
Refer to Figures 83 and 84 for views of mountings.
Attaching bolts at front pivot mountings should be
checked at regular intervals for tightness. Loose mount­
ings will allow shifting of cab and eventual failure of
other items connecting cab to chassis. Front pivot
mountings have fittings for lubrication purposes.
Rear mounting has positive locking mechanism to re­
tain cab in normal operating position in relation to chas­
sis frame. The rear mounting also includes an additional
safety catch.
Cab hold-down catch shaft is equipped with a lubrica­
tion fitting.
A check link is provided near the right front mounting
which limits the distance cab can be tilted forward and
automatically locks the cab in the full-tilt position. Check
link must be released before cab can be returned to nor­
mal operation position.
Interconnected with the cab front mountings is a torsion
bar which is under load when cab is in either the operat­
ing or full-tilted position. Right end of bar is anchored
to cab bracket and left end is anchored to frame bracket
as shown.
Bar is free when cab is tilted part way, therefore, tor­
sion bar assists operator in both the raising and lowering
of cab.
CAUTION:
Under no circumstances should the
bolts which attach torsion bar right anchor
bracket to cab and the torsion bar left anchor
bracket to frame be removed when cab is in op­
erating, or full tilt positions which is when bar
is loaded. An iniury could result when anchor
bracket becomes free and torsion bar twist is
