SAF-HOLLAND XL-LG327-01 Formula 150 Landing Gear – Maersk Sealand (Manufactured after March 1, 2000) - Manual (Page 2)

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 with a molybdenum-type grease through
the grease fittings provided in the legs two times a year or
as required. Add one quarter pound grease at each
grease fitting.
2. Lube 2-speed gears through the grease fitting in the
gearbox two times a year or as required. Add one
quarter pound grease at each grease fitting.
TROUBLE SHOOTING: HARD-TURNING
LANDING GEAR – CHECK THE FOLLOWING:
1. Binding cross shaft. Bolts in the cross shaft must not
be over tightened 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 a crankshaft extension is used, check for alignment
with crankshaft.
7. Binding shaft bushings–bushings must have
adequate clearance for operation. Check mounting
for proper clearance.
8. 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 and 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.
NOTE: Individual parts are indicated in bold numbers
throughout the following text, and may be
referenced to the exploded view found on page 4.
SINGLE SPEED LEG DISASSEMBLY:
1. Remove the landing gear from the trailer.
2. Remove rust and burrs from the end of the shaft (11),
and lubricate to ease removal.
3. Remove the screws (5) from the cover (6), then remove
the cover and gasket (7). Remove excess grease.
4. Remove the spring pin ( 8) from the mounting plate side
of the drive shaft (11).
5. Slide the drive shaft ( 11) until the woodruff key (9)
is exposed from inside the pinion gear (10). Remove
the woodruff key.
6. Continue sliding the drive shaft (11) out to remove the
pinion gear (10) and washer (12).
7. Remove the bevel gear (13) from the top of the screw.
This may require a 4˝ two-arm gear puller, or, the land-
ing gear can be turned upside down and tapped on a
block of wood to remove the bevel gear.
Step 8 will allow the inner leg to
drop out of the outer leg which may
cause injury. Stand clear.
8. Slide the groove pin (14) out, and then remove
the washer (15).
NOTE: The groove pin is easier to remove if it
is rotated from corner to corner.
9. Lift the outer leg (2 or 3) off the inner leg (1).
10. Remove the thrust bearing (17) and collar (18) from
the top of the screw. If the collar is hard to remove, tap
it lightly with a hammer from below.
SINGLE SPEED LEG REASSEMBLY
1. Replace all worn or broken parts.
2. Install the collar ( 18) onto the screw of the inner leg
(1), contoured side down, and tap down until it is well
seated on the shoulder of the screw. Place the thrust
bearing (
17) on top of the collar.
3. Place the outer housing ( 2 or 3) over the inner
leg ( 1). The hole in the top of the screw should be
clearly visible.
4. Install the washer (15) over the top of the screw. Slide
the groove pin (14) through the hole in the top of the
screw. Corner to corner rotation of the hole facilitates
this operation.
Install the bevel gear ( 13) over the top of the screw
and position it so that the slot in the bottom of the
gear captures the groove pin (14). The screw should be
level or slightly higher than the top of the bevel gear.
5. Slide the drive shaft ( 11) through the bushing in the
front (non-mounting plate side) of the outer housing
(2) then through the pinion gear (10) and washer (12).
Make sure the pinion gear is oriented toward the
mounting plate side of the housing, as shown in the
exploded view on page 4, and the keyway (in the drive
shaft) for the woodruff key (
9) is facing up.
6. Install the woodruff key (9) into the drive shaft (11).
Align the key with the slot in the pinion gear (10).
Slide the drive shaft in as far as it will go. Check to see
that the gears turn freely.
7. Press the spring pin (8) into the hole in the drive shaft
(11) on the mounting plate side of the housing.
8. Fill the top of the outer housing (2 or 3) with
approximately one pound of permanent type grease
— to the bottom of the drive shaft (11).
9. Install the gasket (7), top cover (6), and screws (5).
Do not over tighten the screws.
10. Reinstall the landing gear onto the trailer. Make sure
both legs are extended to the same length before
bolting them to the trailer. After the legs are bolted to
the trailer, install the cross-drive shaft (36) with hex
bolts (20) and nuts (19). The cross-drive shaft must
have enough end play, and must rotate freely.
The mounting bolts should be torqued to
100 ft-lbs. minimum.
