TWO SPEED LEG DISASSEMBLY
1. Remove the landing gear from the trailer.
2. Remove the nut (19), bolt (20), washers (21), and
crank (22).
3. Remove rust and burrs from the ends of the shafts (27
and 32), and lubricate to ease removal.
4. Remove the spring pin (8) and washer (43) from the
gearbox side of the drive shaft (32).
5. Remove the nuts (23) and bolts (24) from the gearbox.
6. Remove the outside gearbox half (25) and the gearbox
gasket (26). Remove excess grease.
7. Slide the crank shaft (27) out. The cluster gear (28) will
be attached to the shaft. To remove the gear from the
shaft, remove the roll pin (30) and slide the gear back
to expose the other pin (31). Remove the pin (31) from
the crank shaft.
8. Remove the screw ( 5) and shifter spring (29) from
inside the gearbox half.
9. Remove the screw ( 5) from the cover. Then, remove the
cover (6) and gasket (7). Remove excess grease.
10. Slide the drive shaft (32) until the woodruff key (9) is
exposed from inside the pinion gear (10). Remove the
woodruff key.
11. Continue sliding the drive shaft to remove the spacer
( 37), cluster gear (33), woodruff key (9), spacer (16)
from the gearbox.
12. Slide the drive shaft ( 32) through the housing and
remove the washer (12) and pinion gear (10).
13. Follow steps 7 through 10 in the “Single Speed Leg
Disassembly” instructions, found on page 2, to finish
the disassembly of the landing gear.
TWO SPEED LEG REASSEMBLY
1. Replace all worn or broken parts.
2. Follow steps 2 through 4 in the “Single Speed Leg
Reassembly” instructions, found on page 2.
3. Slide the drive shaft ( 32) through the bushing on the
mounting plate side of the outer housing (3).
Orient the washer ( 12) and the pinion gear (10) next to
the gearbox, as shown in the exploded view on page 4.
Continue to slide the shaft through the pinion gear
and washer, and into the gearbox.
Rotate the shaft so the last keyway is facing up.
Install the woodruff key (
9) and slide the shaft in as far
as it will go.
4. Slide the spacer ( 16) onto the drive shaft (32) with the
open side facing out.
Insert a second woodruff key (9) into the keyway on
the shaft, and slide the cluster gear (33), large side
first, onto the shaft.
Align the slot in the cluster gear with the key, and
slide the gear on as far as it will go.
Slide the spacer (37) onto the drive shaft (32) until it
contacts the cluster gear.
5. Insert the pin (31) into the crank shaft (27). Slide the
cluster gear (28) onto the shaft until the pin engages
the slot in the gear.
Insert the roll pin (30) into the hole in the crankshaft,
in front of the cluster gear.
The roll pin (30) must not
extend more than 1/8˝ above
the shaft surface because
interference may occur resulting
in difficult shifting.
6. Install the shifter spring (29) into the inside gearbox
half and lightly tighten the screw (5) which holds the
shifter spring in position.
7. Insert the crank shaft (27) through the shifter spring
(29), then through the gearbox bushing.
Tighten the screw ( 5) that locates the shifter spring.
Continue sliding the crank shaft until the shifter
spring seats in either groove in the shaft, and there
is full engagement between cluster gear (
28) and
cluster gear (33).
8. Grease the gearbox gears with one pound of
permanent type grease. Install the gasket (26),
gearbox cover (25), bolts (24), and nuts (23). Tighten
to 10 ft.-lbs. torque.
9. Follow steps 8 through 10 in the “Single Speed Leg
Reassembly” instructions, found on page 2, for the rest
of the assembly and installation instructions.
ALIGNMENT:
Using a square, check that both landing gear legs are
square with the trailer and parallel with each other as
shown. Bent or damaged legs are an indication of
possible damage to the lift screw, lift nut or other internal
components and should be replaced.
