Troubleshooting
9. Troubleshooting
PROBLEM
POSSIBLE CAUSE
RESOLUTION
Hard to Crank
Landing Gear
Turning the crank in the
wrong direction
Refer to “Landing Gear Operation” for proper crank rotation.
Attempting to raise or lower
trailer in high gear.
Shift into low gear. DO NOT ATTEMPT TO LIFT OR LOWER IN HIGH GEAR
.
Doing so could result in damage
to the landing gear.
Cross shaft binding.
Inspect cross shaft bolts. Back off bolts to allow lateral (side to side) movement of the cross shaft.
Straighten or shorten cross shaft to eliminate binding.
Misaligned landing gear legs. Legs MUST be parallel and extend and retract evenly. Remove cross driveshaft and adjust landing gear legs
to same height.
Lack of grease.
Grease landing gear legs as provided in the “Lubrication” section.
Damaged lift screw or nut.
Check landing gear for signs of impact (accident) damage. Disconnect cross shaft and crank legs individu-
ally to determine which leg is damaged. Replace entire retract assembly or damaged leg.
Interference between powder
metal bushing or jackshaft of
gearbox and trailer mounting
surface.
Trailer mounting surface may need to be modified to ensure no interference between bushing or jackshaft
and trailer surface.
Upper housing or retract tube
may be bent.
Replace damaged part(s) or landing gear.
Excessive wear or damage
to pinion, bevel, input, idler
and/or output gears.
Replace damaged gears.
Bearing boss is pushed inside
housing.
Replace jackshaft and O-ring with jackshaft repair kit designed for landing gear models sold after January 2013.
Weld blow through where
strut bracket is welded to
housing.
Grind weld as required and re-weld. (With no-load on landing gear, the retract tube should have free play
inside the housing.)
Hard to crank landing
gear under load only.
Damaged collar.
Replace the collar
Damaged thrust bearing.
Replace the thrust bearing.
Crankshaft jams or
skips while turning.
Inner leg screw damaged.
Examine the lift nut and screw of the inner leg assembly for impact (accident) damage. Replace
components or leg as necessary.
Worn, broken, or damaged
gears (missing teeth).
Examine pinion, bevel pinion and all gearbox gears for missing teeth or other signs of damage or wear.
Replace components as necessary.
Landing gear will NOT
shift between gears.
Low input gear is frozen or
binding on the shift shaft.
Follow procedures in the Troubleshooting Guide XL-LG11424TS-en-US to restore easy shifting.
Gearbox leg operates
but opposite leg
DOES NOT.
Broken/damaged cross
driveshaft bolt.
Replace cross driveshaft bolt.
Broken/damaged cross
driveshaft.
Replace cross driveshaft.
Bevel gear pin/pinion gear pin
sheared in non-gearbox leg.
Remove upper leg cover. Check for damaged or missing pins under bevel gear, or in pinion gear and
replace as necessary.
Bevel gear/pinion gear
damaged in non-gearbox leg.
Remove upper leg cover. Check for damaged gears and replace as necessary.
Non-gearbox leg
operates, but gearbox
leg DOES NOT.
Bevel gear pin/pinion gear pin
sheared in gearbox leg.
Remove upper leg cover. Check for damaged or missing pins under bevel gear, or in pinion gear and
replace as necessary.
Bevel gear/pinion gear
damaged in gearbox leg.
Remove upper leg cover. Check for damaged gears and replace as necessary.
Both legs will NOT
operate, shift shaft
will turn but output
shaft DOES NOT turn.
Damaged input, idler, and/or
output gear.
Remove gearbox cover. Inspect and replace broken gears.
Gear pin(s) sheared in gearbox. Remove gearbox cover. Inspect and replace broken pins.
Both legs will NOT
operate, but shift
shaft and output
shaft turn.
Bevel gear pin/pinion gear pin
sheared in both legs.
Remove upper leg covers. Check for damaged or missing pins under bevel gear, or in pinion gear and
replace as necessary.
Bevel gear/pinion gear
damaged in both legs.
Remove upper leg covers. Check for damaged gears and replace as necessary.
Legs locked and will
NOT turn
Bent retracting screw or
damaged riser nut and screw.
Check landing gear for signs of impact (accident) damage. Disconnect cross shaft and attempt to crank legs
individually to determine which leg is damaged. Replace entire retract assembly or damaged leg.
