Converting Category 4N/3 Convertible Quick Coupler Lower Hooks

CAUTION: Use proper lifting device when converting coupler. Failure to do so can result in personal injury.

NOTE: Use Category 4N whenever possible.

A second person is recommended to align components during conversion.

If category 4 lower hooks are used on category 3 implements, bushings are needed over category 3 pins; these bushings can be purchased through your John Deere™ dealer.

1. NOTE: Lower hooks are not marked for left-hand or right-hand side. Do not move lower hooks from one side to other.

   NOTE: Because lower hook (E) has category 3 hook (F) on one end and category 4N hook (G) on opposite end, it is used for both category 3 and 4N simply by turning it end for end.

4. Remove lower hook by rotating it down and to rear of coupler, then sliding it out at front of coupler.

5. Install lower hook, with desired end facing out. Using a reverse motion of removal, rotate it up and in.

6. Install pin, retainer, and cap screw.
