SAF-HOLLAND XL-LG315-01 Formula 150 Landing Gear (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 and access holes 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
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.
WARNING
DO NOT use lubricants
containing teflon.
SINGLE SPEED LEG DISMANTLING PROCEDURE:
1. Remove landing gear from trailer.
2. Remove rust from projecting end(s) of shaft (11), and
lubricate for easy removal.
3. Remove screws (5), cover (6), and gasket (7).
4. Tap out pins (8) from shaft (11). Remove shaft (11),
pinion gear (10) and key (9).
5. Tap out pin (14) from top of screw.
6. Remove washer (15).
7. Slip pin (14) out of elevating screw and remove.
Remove washer (15).
8. Upper leg (2) and lower leg (1) can now be separated.
9. Remove bushing (16).
10. Remove bearing (17) and collar (18) from lower leg (1).
2-SPEED GEARBOX LEG DISMANTLING
PROCEDURE:
1. Remove landing gear from trailer.
2. Remove nut (19), bolt (20), washers (21), and crank
handle (22).
3. Remove rust from shafts (27) and (32), and lubricate
to ease removal.
4. Remove nuts (23) and bolts (24) from gearbox.
5. Remove gearbox cover (25) and gasket (26).
6. Remove shaft (27) with gear (28) assembled.
To remove gear from shaft, remove roll pin (30),
and slide gear from shaft (27). Remove pin (31)
from shaft (27).
7. Remove screw (5) and shifter spring (29).
8. Remove screws (5), cover (6), and gasket (7).
9. Drive pins (8) from shaft (32).
10. Remove gear (10) and washer (12). Remove spacer
(37), gear (33), key (9), and spacer (16).
11. Follow procedures outlined in steps 6 through 10 in
"Single Speed Leg Dismantling Procedure," to finish
leg dismantling.
12. Remove bushings (34) or (35) if required.
SINGLE SPEED LEG ASSEMBLY PROCEDURE:
1. Replace all worn or broken parts.
2. Place collar (18) on elevating screw, followed by
thrust bearing (17). Note: Contoured side of collar
must face down.
3. Place upper leg (2) over lower leg (1). Press down until
hole in the elevating screw is clearly visible through
the hole in the bearing block in the upper leg (2).
4. Install washer (15) and slip pin (14) in hole in the
elevating screw. Install bevel gear (13) and position
it so that the slot on the bottom of the gear captures
pin (14).
5. Place the shims (12) and pinion gear (10) on top of the
bevel gear with the roll pin hole in the pinion
gear facing up.
5. Install shaft (11) in outer leg (2) through shims (12)
and gear (10), making certain gear is oriented as
shown in the exploded view. Initially start with
two shims.
