CM235 – 4.5t Electric Coupling Installation Instructions
- Install 4.5t electric coupling over the tow ball.
- Remove the nut.
- Adjust the side bolt until tight, then back off the bolt 1/2 turn.
- Reinstall the nut and retighten it.
- This nut puts pressure on the coupling tongue to prevent decoupling.
Repeat the installation instructions if the 4.5t electric coupling starts feeling loose.
It is essentially an “R” clip, lynchpin, or another suitable device, such as a padlock, placed behind the handle’s lower part.
Use 4 x 5/8″ Grade 12 bolts of suitable length, washers, and nylocks. It must be bolted and cannot be welded to the drawbar.
Marine Applications
Marine brakes use hydraulic brakes and do not require the park brake attachment on the 4.5t electric coupling. This attachment is for use with electric brakes.
Cutting the brake handle from the coupling is permissible without altering its integrity. Why? Therefore, the park brake attachment is optional and not part of the testing procedures.
Important Notice
The approval letter’s CTA is the same as the one on the invoice.
Show vehicle inspectors this Invoice during your trailer or vehicle inspections if required.
