OPERATING, MAINTENANCE,
AND REPAIR PROCEDURES
XL-LG326-01 1
NOTE: This model is similar to other LG150 models, but
does contain several unique parts. See Holland Publication
LG 217 for other LG150 models.
DO NOT deviate from these instructions. Any changes or
deviations will void all warranties, expressed or implied,
unless written consent is first obtained from the factory.
OPERATION OF HOLLAND
FORMULA 150 LANDING GEAR:
NOTE: Holland Formula 150 2-speed gearbox has high
and low range gears. High range gear is to be used only for
rapid traverse up from and down to the ground and
is not intended to lift or lower any load. For additional
information, see Holland publication XL-FW302-XX,
entitled “Fifth Wheel Operating Instructions”.
TO EXTEND:
On outside mounted landing gear, engage the crank with
the crankshaft and turn the crank clockwise. Inside mounted
landing gear are extended by turning the crank
counterclockwise. Using high gear, lower the landing gear
until the pads make contact with the ground. To reduce the
load on the fifth wheel, shift to low gear and crank an
additional four to eight turns. Leave the landing gear in low
gear and store the crank handle in the holder provided.
TO RETRACT:
On outside mounted landing gear, engage crank with
crankshaft and turn the crank counterclockwise. Inside
mounted landing gear are retracted by turning the crank
clockwise. Retract the landing gear using low gear until
unloaded. Then shift to high gear and continue cranking
until fully retracted. Leave the crankshaft engaged to
prevent road vibration wind-down. Store the crank in
the holder provided.
MAINTENANCE:
LUBRICATION:
Although Formula 150 landing gear are adequately
greased and packed with high quality lubricants when
manufactured, it may be necessary to periodically
supplement this lubrication to maintain satisfactory
performance for your particular application.
1. Lube both legs through the grease fittings and access holes
provided in the legs two times a year or as required.
2. Lube 2-speed gears through the grease fitting in the
gearbox two times a year or as required.
TROUBLE SHOOTING — HARD TURNING
LANDING GEAR — CHECK THE FOLLOWING:
1. Binding cross shaft. Bolts in the cross shaft must not be
overtightened to prevent lateral movement of the cross
shaft.
2. To determine which leg turns hard, remove the cross
shaft and operate each leg individually.
3. Landing gear may be bent or damaged.
4. Alignment – legs must be parallel and extend and
retract evenly.
5. Legs and gearbox may need additional lubrication.
6. If crankshaft holder or extension are used, check
for alignment with crankshaft.
7. If a through-axle is used, check for binding where
the axle goes through the legs.
8. Binding shaft bushings – bushings must have
adequate clearance for operation. Check mounting
for proper clearance.
9. Examine nut and screw assembly for damage caused
by dropping of the trailer.
TROUBLE SHOOTING — GENERAL:
Follow the dismantling and assembly instructions in
this manual.
If crankshaft jams or skips while turning–examine parts
(10 & 13) and all gearbox gears for worn, broken, or
missing teeth.
If the landing gear will not stay in gear while
cranking–check the condition of shifter spring (29),
shifter grooves in crankshaft (27) and cluster gear (28).
Replace as required.
CAUTION
• Always grip crank handle securely.
• Always grip crank handle securely
with both hands before shifting.
• Never shift landing gear under load.
• Never leave the crank unsecured.
• Never raise or lower a loaded
trailer in high gear.
WARNING
DO NOT use lubricants
containing teflon.

NOTE: Holland Olympix 2-speed gearbox has
high and low range gears. High range gear
is to be used only for rapid traverse up and
down from the ground and is not intended
to lift any load. For complete tractor-trailer
coupling and uncoupling procedures, refer to
Holland publication FW-TE-14-B, entitled
“Fifth Wheel Operating Instructions”.
To Extend:
On outside mounted landing gears, engage the crank
with the crankshaft and turn the crank clockwise.
Inside mounted landing gears are extended by
turning the crank counterclockwise. Using high gear,
lower the landing gear until the pads make contact
with the ground. To reduce the load on the fifth
wheel, shift to low gear and crank an additional 4 to
8 turns. Leave the landing gear in low gear and store
the crank handle in the holder provided.
To Retract:
On outside mounted landing gears, engage the crank
with the crankshaft and turn the crank
counterclockwise. Inside mounted landing gears are
retracted by turning the crank clockwise. Retract the
landing gear using low gear until unloaded. Then
shift to high gear and continue cranking until fully
retracted. Leave the crank shaft engaged to prevent
road vibration wind-down. Store the crank in the
holder provided.
MAINTENANCE:
Lubrication:
Although Olympix landing gears are adequately
greased and packed with high quality lubricants
when manufactured, it may be necessary to
periodically supplement this lubrication to
maintain
satisfactory
performance for
your particular
application.
1. Lube both
legs through
the grease fittings and access holes provided in
the legs two times a year or as required.
2. Lube 2-speed gears through the grease fitting in
the gearbox two times a year or as required.
Trouble Shooting — Hard Turning Landing
Gears — Check the Following:
1. Binding the cross shaft — Bolts in the cross
shaft must not be overtightened to prevent
lateral movement of the cross shaft.
2. To determine which leg turns hard, remove the
cross shaft and operate each leg individually.
3. Landing gear may be bent or damaged.
4. Alignment — Legs must be parallel and extend
and retract evenly.
5. Legs and gearbox may need additional lubrication.
6. If crankshaft holder or extension are used,
check for alignment with crankshaft.
7. If a through-axle is used, check for binding where
the axle goes through the legs.
8. Binding shaft bushings — Bushings must
have adequate clearance for operation. Check
mounting for proper clearance.
9. Examine nut and screw assembly for damage
caused by dropping of the trailer.
Trouble Shooting — General:
Follow the dismantling and assembly instructions in
this manual.
If the crankshaft jams or skips while turning —
Examine parts (23 and 26) and all gearbox gears for
worn, broken, or missing teeth.
If the crankshaft will not stay in gear while
cranking — Check the condition of the shifter spring
(36), the shifter grooves in crankshaft (39), and the
cluster gear (35). Replace as required.
CAUTION
1. Always grip crank
handle securely.
2. Always grip crank handle
securely with both hands
before shifting.
3. Never shift landing gear
under load.
4. Never leave the crank
unsecured.
