6.
Raise trailer tongue and rear of vehicle with jack. Lower yoke of snap up bracket until it is parallel with the ground, and
slip the closest link over the hook (If there are less than 4 links between hook and u-bolt adjust ballmount angle
rearward, and repeat procedure). With the snap up bracket handle over the yoke, raise until yoke has passed “over-
center”. Slide the safety pin through the small hole to lock the yoke in place. Repeat for other side.
7.
Lower jack. Re-measure front wheel well reference point. The front wheel well height should be equal to or lower than
the original measurement. If the front wheel well height is higher than originally measured, reduce the number of links
between the yoke hook and spring bar (4 links min.)
and recheck the wheel well measurement. If the front wheel well is
lower than originally measured, increase the number of chain links between the yoke hook and spring bar and recheck
the wheel well measurement. If the original wheel well height is not achievable, it is preferred that the wheel well height
is lower after the spring bars are loaded. If there are no more chain links for adjustment, the head assembly must be
tilted forward. The trailer must be uncoupled and the upper bolt removed from the head assembly. The head is then
pivoted up as appropriate. Reassemble and recheck the wheel well height.
Check to see if trailer is level, if not, you may need to re-adjust ballmount angle and / or position.
Check to see that there is room for the spring bar and chain to move freely when turning a corner.
NOTE:
Some surge brakes will not work with weight distributing hitches. Check with manufacturer. Do not use
sway control with surge brakes.
LUBRICATION
1.
Lubricate the ballmount sockets and spring bar trunnions to prevent rapid wear. When hooking-up, place one drop of oil
on the top and a second drop on forward side of upper trunnion. Place a third drop on the rear side of lower trunnion
before inserting trunnion into ballmount. Use a heavy oil or grease. Don't forget to lubricate the hitch ball with one or
two drops also. Trunnions should be lubricated each towing day. Lubricate lower trunnions with one drop at contact
point between trunnion and lower socket. Excess oil, dirt, and grit should be wiped out whenever trailer is uncoupled.
SURGE BRAKES
Some surge brakes will not work with weight distributing hitches. CHECK TRAILER AND/OR SURGE BRAKE
OPERATING INSTRUCTIONS FOR ANY SPECIAL REQUIREMENTS REGARDING WEIGHT DISTRIBUTING
HITCHES. Do not use sway control with surge brakes.
