Frequently Asked Questions and Technical Support
-
A: For non-NY State titles follow this procedure: VIN Plate Non-NY. For NY State titled trailers, follow this procedure: VIN Plate NY State Only.
-
A: Yes, here are the SAE J560 plug pin-outs for Electric and Air Brake Tags as well as Lowboys.
1. Tag, Pintle Pull: Electric Brake or Air Brake
2. Lowboy, 5th Wheel Pull: All Air Brake -
A: Strobe lights are powered via the black wire in the harness per the Strobe Light schematic.

A: When we manufacture our trailers and goosenecks, we intentionally design the mating surfaces between the neck and the Haul Pin where it passes through the alignment tray to a close tolerance fit. When extending the haul pin into the alignment tray lock position, full 3,000 PSI hydraulic pressure is delivered to ensure a positive lock. However, on retract (unlock), the hydraulic cylinder has an internal relief set at 550 PSI (plus/minus 75 PSI), which is a safety feature designed to protect the compression block cross bar from being damaged during retract in the event the cross bar is inadvertently left in the transport position (ie, not rolled out of the way). Accordingly, because the haul pin only has 550 PSI of hydraulic pressure on retract, it is possible that a brand new pin may fail to retract due to a close tolerance fit combined with minor galling where it mates with the alignment tray.
An effective solution for dislodging a stuck haul pin follows. First, apply the trailer spring brakes. Next raise the main lift cylinders, using the ‘B’ Spool Lever, which will raise the trailer off of the ground about 12 to 16 inches. Make sure the compression block cross bar is rolled out of the way. Raise the hauling pin ‘C’ Hydraulic Spool Lever and, at the same time, start lowering the trailer bed by pulsing (or bouncing) the ‘B’ Spool Lever downward. Again keep the ‘C’ Lever raised, while simultaneously, pulsing the ‘B’ Lever downward. This should release the pin. Once the pin is retracted and the neck is separated from the bed, put the haul pin in the extended position, allowing it to protrude from the bottom of the neck. Inspect the pin for galling and remove galling with a fine flat file or grinder. Next, inspect the haul pin hole in the bed alignment tray. You will observe a ¾” thick steel ring with a 2.5” ID center hole, through which passes the haul pin. Using a die grinder, remove any galling in the 2.5” ID hole. Next, concentrate on the front of the ring and remove approximately 1/16” to 1/8” of steel from the center hole at the front of the ring. This will provide the necessary clearance for smooth retract yet not affect the service life of the ring itself. -
A: Warranties for our pony motors are handled by the motor manufacturer. Both Honda and Kohler engines come with a FULL 3-Year commercial use Warranty. Both Honda and Kohler have an extensive dealer network throughout N. America. You can find the nearest dealers on their websites:
1. Honda – https://engines.honda.com/dealer-locator
2. Kohler – http://www.kohlerengines.com/wheretobuy/landing.htm -
A: Please see the attached operating instructions.
-
A: When power is supplied to the trailer (truck key placed in the ‘ON’ position), the trailer’s Electronic Control Unit (ECU) does a self-test and, upon satisfactory completion, will blink the amber ABS light on and then it will go off and remain off. If the amber ABS light remains on after self-test, there is a problem and the below ‘Blink Test’ procedure should be followed.
-
A: It indicates the ABS feature of your service brakes is not working properly. Your service brakes will still work however, you may not have anti-lock braking. The ABS module has a test mode which can be used to determine the specific problem with the ABS system. Follow the procedure shown on the ABS Blink Test document.
-
A: Yes, select the appropriate schematic for your trailer (tag is a pintle hitch pull; Lowboy is a 5th Wheel pull).
1. Tandem Axle Tag Mfg 2001 onward (with 400 Series ECU) or Tandem Axle Tag Mfg between 1998-2001 (with 472 series ECU & Relay)
2. Tri-axle Tag: Model 25XPL (with lift axle) or Model 25XPT (no lift axle)
3. Tandem Axle Lowboy
4. Tri-Axle Lowboy -
A: The answer varies slightly by axle manufacturer and capacity. Use the appropriate document as follows:
1. Dana-Spicer D22 Axle (all lowboys and many 20 – 25 Ton Tags)
2. Dexter D225 Axle (many 20-25 Ton Tags)
3. Dexter 10-12K Axle (all 10 Ton and 12 Ton Tags) -
A: Please see the Air Brake Chamber Application Chart.
-
A: All Lowboys have Dana-Spicer ‘Quick Fit’ Style Shoes. For Tags, please see the Tag Air Brake Shoe Identification chart.
-
A: Disconnect the trailer nose harness from the truck. Pull the pin from the BAS and try to move the trailer. If the brakes are locked, your BAS and battery are working correctly.
-
A: The most efficient means to communicate a question or problem to us is to complete and submit the below form. We will reply – guaranteed! If you need any type of documentation or schematic, please be sure to provide a Fax # or Email address. Because air schematics are in color (which aids in troubleshooting), it is always better to provide an email address if you have an air system question.
Question or Problem: The more detailed the question or problem, the better we can answer. (Hint. At a minimum let us know the applicable trailer system so your question can be routed to the correct person. For example you could use system names such as Air Suspension, Spring Suspension, Gooseneck Hydraulics, Ramp Hydraulics, Air Service Brakes, Air Spring Brakes, Electric Brakes, or Amber Strobe Lights.)
