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.

and REPAIR PROCEDURES

Operating, Maintenance, and Repair Procedures

for Series CS615 Fruehauf

Replaceable Landing Gear

CAUTION

• Always grip crank handle securely.

• Always grip crank handle securely
with both hands before shifting.

under load.

• Never leave the crank unsecured.

• Never raise or lower a loaded
trailer in high gear.

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. Remove plug (8). Using plug hole, tap out pin (9) from
gear (10).

5. Remove shaft (11), gear (10), and shims (12). Note the
quantity and location of shims removed.

6. Remove bevel gear (13) from elevating screw.

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 the screw
in the lower leg.

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. Remove plug (8). Using plug hole, tap out pin (9) from
gear (10). Remove shaft (32) with gear (33) assembled.

10. Remove gear (10) and shims (12). Note quantity and
location of shims removed. To remove gear (33) from
shaft, remove drive pin (9) and slide gear off shaft.

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. Install bushing (16) into place in upper leg (2).
Bushing must be flush with the top of the bearing
block in the leg.

4. Place upper leg (2) over lower leg (1). Press down until
hole in the elevating screw is clearly visible through
