3. Pre-Installation Instructions
Prior to installation of the landing gear, correctly size the
legs to the trailer. There MUST be 12" (304.8 mm) minimum
ground clearance, when the landing gear is fully retracted.
Ensure that the legs have sufficient travel to raise the trailer
from the fifth wheel 1-3" (25.4 - 76.2 mm) without over-
extension. DO NOT force the landing gear past its stops.
Failure to operate the landing gear within
the maximum extension or retraction
including repeated winding to its physical
stops could, if not avoided, cause
damage to the landing gear.
IMPORTANT
Provide adequate clearance between the
jack shaft bushings, jack shaft, shift shaft
and the trailer frame. If the bushings or
shafts are tight against the frame, damage
and hard cranking will result (Figure 7).
Failure to provide adequate clearance
between the jack shaft bushings, jack shaft,
shift shaft, and the trailer frame could
cause hard cranking and wear which, if not
avoided, could result in minor/moderate
injury or component damage.
Before installation of the landing gear, ensure that both legs
are in the fully retracted position. Both landing gear legs
MUST be extended equally at all times.
Failure to extend the legs evenly could
cause trailer to tip over, which, if not
avoided, could result in death, serious
injury, or property damage.
Failure to extend the legs evenly could
increase the potential for landing gear
spring back, which, if not avoided, could
result in death or serious injury.
Ensure the cross-shaft is of adequate length for the application.
When installed, the cross-shaft should have 1/8" (3 mm) to
3/8" (9.5 mm) of side to side free play. It should also rotate
freely with the jack shaft when installed (Figure 8). A cross
shaft which is too long will cause binding resulting in stiff
operation and excessive bushing wear.
Failure to ensure the cross-shaft is
installed at adequate length and has free
play could result in stiff operation which, if
not avoided, could result in property damage.
