631E Series II Wheel Tractor-Scrapers Seat Belt Caterpillar

Note: This machine was equipped with a seat belt when the machine was shipped from AVSpare. At the time of installation, the seat belt and the instructions for installation of the seat belt meet the SAE J386 standards. See your AVSpare Dealer for all replacement parts.

Always check the condition of the seat belt and the condition of the mounting hardware before you operate the machine.

If the bolt that holds the two parts of the seat belt mounting hooks and the nut that holds the two parts of the seat belt mounting hooks are not correctly installed, the hooks can separate. This allows the seat belt to separate from the belt mounting.

Inspect the hooks on each half of the seat belt in order to make sure that the bolt and the nut are correctly installed.

Remove the old bolt and the old nut, if the bolt and the nut are not correctly installed. Install a new bolt and a new nut.

Seat Belt Adjustment

Adjust both ends of the seat belt. The seat belt should be snug but comfortable.
