17000, 17001, 17002 WEIGHT DISTRIBUTION KIT
ADJUST HOOKUP (IF NECESSARY)
A weight distributing system is properly set up and coupled when the tow vehicle has settled with the front
wheel opening "F" at the original uncoupled dimension measured and slightly lower in the rear "R". See
Figure 11.
~ This will assure the front wheel load remains unchanged. This results in good handling and the desired
load on the rear axle.
~ The front of the vehicle should never settle more than the rear. See Figure 12. If necessary increase
the number of chain links between lift unit and spring bar.
~ 3/4 - 1 ton and/or long wheelbase vehicles will typically settle with the front wheel opening "F" at the
original dimension to 1/2" higher than original. This will still allow acceptable front wheel loads, good
handling and the desired load on the rear axle and trailer axle.
~ If the rear suspension sags too much, additional leveling is required. The front wheel opening "F" may
ONLY be settled lower than the original dimension IF the rear wheel opening "R" has settled by a
greater amount(At least 1").
1. If additional leveling is required, decrease the number of chain links between snap-up bracket and spring bar.
2. There must be at least 5 links between the snap-up bracket and the spring bar. This is
necessary for proper operation of the spring bars during turns. If there are less than 5 links, the angle
of the head assembly must be increased.
3. When the desired settling is achieved, mark the hooked chain link with paint for future reference.
NOTE:
SURGE BRAKES usually require a small amount of fore-aft movement for their actuating mechanisms to
function. To avoid restricting movement, it may be necessary to increase the number of chain links between
the snap-up brakcets and the spring bars. CHECK TRAILER AND/OR SURGE BRAKES OPERATING
INSTRUCTIONS FOR SPECIAL REQUIREMENTS REGARDING WEIGHT DISTRIBUTING HITCHES.
TIGHTEN HEAD FASTENERS
1. Tighten 3/4 bolts and locknuts to 200 lb-ft. Tighten setscrew to 50 lb-ft.
CHECK ALL CONNECTIONS BEFORE TOWING
1. Check the following: pin and clip securing shank to receiver, head to shank fasteners, ball nut, coupler latch,
snap-up bracket bolt, safety chains, lights and turn signals, and braking system, including breakaway switch.
LUBRICATION
1. TRUNNIONS SHOULD BE LUBRICATED EACH TOWING DAY. FAILURE TO DO SO WILL
RESULT IN EXCESSIVE POCKET AND TRUNNION WEAR. Use a heavy oil or grease.
2. Excessive oil, dirt, and grit should be wiped out of pockets whenever trailer is uncoupled.
3. Clean hitch ball and coupler socket. Coat ball lightly with grease.
