.
TOWING APPLICATIONS:
Trailers, full trailers, doubles and triples operations within the stated capacities. For off-road applications, reduce the capacities above by 25% and use in conjunction with a swivel type drawbar.

DRAWBAR EYE DIMENSIONS:
2.38’ to 3” I.D. with 1 .62” to 1.75” diameter section.

MOUNTING
1. Use mounting structure sufficient strength to support the rated capacity of the pintle hook in accordance with SAE J849 and SAE J847 respectively.
2. Use the hole pattern described on the reverse.
3. Use (6) .75” grade 8 fasteners, properly tightened.
4. A Holland XA-T-653 air cylinder is recommended for Use with Holland pintle hooks.
5. Adjustment of Holland air-activated plunger:
The Holland XA-T-653 air cylinder is preset for mounting thickness of .50” through 1 .50” with a 1.62” diameter drawbar section. If your mounting structure is different,. Adjust as follows:
A. Loosen cylinder rod jam nut (A) as shown in figure 1
B. Turn the bullet nose (B) out (counterclockwise)
distance equal to the difference between the mounting, structure thickness and 1 .50”. (It may be necessary to consider drawbar cross-section as well).
NOTE: Be sure the cylinder rod and bullet nose have .38” minimum thread engagement. (Factory set engagement is approximately 1 .38”)
C. Retighten cylinder rod jam nut (A) securely.
6. Mount the cylinder and bullet nose assembly, making sure that the air cylinder and bullet nose assembly are in line with the plunger (see figure 1). Adjust as required and tighten
Cylinder bolts securely.
7. Connect the air supply and check for proper operation.
8. Check the plunger adjustment. When properly adjusted, the plunger should tightly grip a 1.25” round bar when energized (see figure 1), and retract far enough when deenergized to allow easy removal of the drawbar.
