Reese 66542 TRUNNION BAR W_HITCH BAR - Manual (Page 3)

INITIAL HOOK UP
NOTE: Car and trailer should be loaded and ready for travel before final leveling.
1. Pick reference points on front and rear wheel wells. Measure and record distance to pavement.
Front wheel well to pavement ___________________ Rear wheel well to pavement __________________.
2. Attach chains to spring bars using U-bolts, flat washers, and locknuts. Let 2-3 threads protrude below locknut. Chain
must not bind.
STANDARD SPRING BAR INTEGRATED CAM SPRING BAR
3. Using tongue jack lower coupler onto ball and close coupler latch.
4. Hold the spring bar away from you (trunnion ribbed side up). Set the bottom knob of the trunnion into the lower socket of
the ballmount (G) and slide the knob into the top slot of the ballmount. The spring bars will fit on either side as they are
not made right or left handed.
5. Position the snap up brackets on trailer
"A" frame so that the chain on the end of
the spring bar is approximately vertical.
Turn 1/2 X 3-1/2 bolt until it contacts frame.
Then tighten 1/4 turn with wrench. DO NOT
OVERTIGHTEN.
6. Raise trailer tongue and rear of car 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 5 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 and rear wheel well
reference points (vehicle should settle evenly, within
about 1/2 inch). If front has settled more than rear,
increase the number of chain links between yoke hook and spring bar. If there are no more links, the angle of the head
assembly must be decreased. The trailer must be uncoupled and the upper bolt removed from the head assembly.
The head assembly is then pivoted up as appropriate. Reassemble. If rear has settled more than front, reduce the
number of links between hook and spring bar. It is preferred that rear of vehicle settle the same or more than the front.
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 bar and chain to move 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 such as "REESE ON THE BALL". Don't forget to lubricate the
hitch ball with one or two drops also. Trunnions should be lubricated each towing day. It is not necessary to unhook the
spring bars however, as there are two oil holes in the ballmount top plate for upper trunnion lubrication. 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.
