ismounted ona bracketattached tothe frame.

2. STEERINGGEAR(THREE-TOOTHROLLER
ANDWORM)(Mechanical)
Athree-toothroller is mounted on needleroller
bearingson a steelcross-shaftinsertedthrough
thesteeringgearshaft.
Theworm is integralwith the steeringtube
and is supported at each endby taperedroller
bearings.Thewormbearingpre-loadisadjusted
bymeans of shimsplacedbetween the housing
andhousingendcover.Thesteeringgearshaft
rotates in twobronzebushingspressedinto the
steeringgearhousing. The three-toothroller
on the shaft is meshedwith the worm.When
thesteeringwheel is turned, the wormrotates
thesteeringgearshaft and roller,moving the
Pitmanarm,which is splined tothe end ofthe
shaftandheld in placewith a nut.
