Installation Manual

HOOK-UP:

NOTE: Set-up and adjust weight distribution system per Installation Instructions for Weight Distribution. Reference

instruction sheet 66006IN for trunnion or 65590IN for round bar styles.

1. Make sure that both cam arm adjustment nuts are backed off sufficiently away from the yoke to allow the cam arm

to slide freely through the majority of its adjustment range.

2. Connect trailer to tow vehicle. Tow vehicle and trailer should be in a straight line. Raise trailer tongue and rear of tow

vehicle with jack. Install spring bar trunnion in ball mount. Spring bars may be used on either side. Mate spring bar

and cam to cam arms. With ends of u-bolt facing outward, slip keyed slot of hanger bracket over button on end of

cam arm, rotate to vertical, and pull chain vertical. Place link of chain on hook of snap-up bracket. Make sure that

slot of bracket is fully engaged in slot of cam arm.

3. Before placing snap-up in position, ensure that the cam of the cam arm is about 1/2” forward of the bend in the

spring bar, since the cam moves rearward as it is lifted by the snap-up bracket. After moving snap-up into the up

position, install safety pin. Install second spring bar using the same number of chain links. Make sure that cams are

mating each other properly.

WARNING! WHILE LIFTING SNAP-UP BRACKET, AND DURING REMAINDER OF SETUP, KEEP

HANDS AND FEET AWAY FROM CAM ARM AND UNDER SPRING BARS. COMPONENTS ARE LOADED

WITH SUBSTANTIAL FORCE AND COULD SHIFT POSITION OR DROP SUDDENLY CAUSING SERIOUS

INJURY.
