NOTE:
• During ball mount adjustment, it may be necessary to raise or lower the L-bracket (L) to get the proper
spring bar load if there is not enough head angle adjustment. If their are not enough washers to get the
dimension shown in fig. 5, move the L-bracket (L) up 1 set of holes.
• If you have a 6” tall frame with a bottom mounted coupler (inverted coupler) it may be necessary to
install brackets (V) and (W) upside down in order to get the L-bracket (L) mounted low enough. This will
lower the L-bracket 1.75” Otherwise their may be too much spring bar pressure.
• Torque both 3/4” nuts(E) to 300 ft.*lbs. when the desired angle is achieved. If a large enough torque
wrench is not available, torque nuts to 150 ft.*lbs. then tighten the nuts an additional 1/4 turn. Do not
lubricate the threads.
BALLMOUNT ADJUSTMENT
•With your trailer NOT CONNECTED to the vehicle, pick
reference points on front and rear wheel wells of your vehicle.
Measure and record distance to pavement. Front wheel well to
pavement __________Rear wheel well to pavement _________.
•Insert the spring bars into the ball mount (A) and secure with
pin (G) and clip (H). Apply a lubricant on the spring bars as you
insert them into the ball mount.
•With the trailer coupled to the ball and the trailer setting level,
(use the tongue jack to level the trailer), the angle adjustment in
the ball mount should have the spring bar 3” below the friction
pad for the 400 lb. system and 4” below the friction pad for the
600 lb. system. See Fig. 5. If needed add or subtract washers (K)
shown in Fig. 1 to get the needed dimension. Each washer added
will move the spring bars down approx. 5/8” to ¾”.
•If you have the 66557 and a tongue wt. of only 250 lbs., you
may need only 1-2 washers.
•If you have the 66558 and a tongue wt. of 600 lbs., you may
need 3-4 washers.
•Install and tighten bolt (F) shown in Fig.1
