Greasing the Tow Ball, Tow Hitch, and Grease Fittings
Your DR 1/2 TON VERSA TRAILER'S Wheel Bearings were greased at the Factory. Prior to using your Trailer for the first time, you
need to lubricate the
Swivel of the Tow Hitch, the Tow Hitch Coupler, and the 2" Ball you will be using. You should also
periodically lubricate the Tow Hitch Swivel, Tow Hitch Coupler, and 2" Ball to reduce wear and rust on these components.
Tools and Supplies Needed:
• Flexible hose grease gun
•
Lithium grease
•
Clean cloth
1. Wipe all dirt, etc., from the Grease Fitting(s) with a clean cloth.
2. Apply enough quality general-purpose lithium grease with a hand-pumped
grease gun to the Tow Hitch Swivel Zerk Fitting, so a small amount of
Grease comes out of the Swivel Fitting (Figure 28)
3. Apply the grease to your 2" Tow Ball to reduce friction on the Tow Hitch
Coupler and to help prevent rusting and seizing of the ball to the Coupler.
4. Apply the grease to the Pivot Pins of the Latch on the Coupler and to the
underside of the Coupler
(Figure 29).
TIP: The Tow Hitch is designed to rotate 360 ° to ease greasing of the
underside of the coupler.
Adjusting the Tow Hitch
A loose connection between the Trailer and Tow Vehicle may cause the
Hitch to disconnect or rattle during use. Always check the Hitch for
proper tension prior to use.
Tool Needed:
19mm Socket or Wrench
1. Attach the empty Trailer to the Tow Vehicle and latch the Locking
Lever. Check for horizontal and vertical play between the Tow
Hitch and the 2" Tow Ball. If the Tow Hitch is loose on the Ball
allowing for play, the Hitch needs to be adjusted. Inversely, if the
Latch is difficult to connect, or disconnect, the Hitch is adjusted too
tightly and needs to be loosened.
2. Unlatch the Locking Lever and remove the Trailer from the Tow Ball.
3. Locate the Adjustment Nut on the underside of the Hitch (Figure 30).
Using a 19mm Socket, or Wrench, rotate the Nut clockwise to tighten
and counterclockwise to loosen.
4. Re-attach the Trailer to the Tow Vehicle and latch the Locking Lever.
Check for horizontal and vertical play between the Tow Hitch and the
Tow Ball. Repeat steps 1-3 until a snug fit is obtained.
