Maintenance Of Quick Release Bracket Cont a Installation Cont

5. As illustrated below, hold the retaining spring (1) away from the plunger (2). Fully depress the plunger and rotate the latch lever (3) fully upward. Lift the latch arm (4) away from the hook (5). It may be necessary to depress the plunger to allow the latch lever to lock. Rotate the latch arm up and out of the way to its fully open position. Depress the plunger and remove the five-position shim plate (6). Remove the right half base (7) by sliding it off the left bracket assembly (8) dovetail.

6. Thoroughly clean the 2 socket head cap screws, the right half base, and the left bracket assembly with a degreaser such as dry cleaning solvent (app D, item 9).

7. Slide the right half base onto the left bracket assembly dovetail. Depress the plunger and reinsert the shim plate into the bracket.

M203a2 Quick Release Bracket

9. The purpose of this procedure is to determine if spring washers will be required. In most cases, spring washers will not be required because the five-position shim plate will be retained within the bracket by the plunger, but can be pulled from the groove using finger pressure while the plunger is fully depressed. Do not use spring washers (10) at this time.

Assemble the bracket to the receiver as follows:

a. Start each screw (9) as illustrated below and tighten with a 5/32" hexagonal wrench until each screw head is just below flush.

b. Continue to tighten each screw until there is no play or movement between the bracket and the receiver c. If you are unable to remove the shim plate, some minor loosening of the screws is allowable in this procedure as long as there is no play or movement between the bracket and the receiver.

NOTE

If you are unable to tighten the screws enough to completely eliminate play or movement between the bracket and the receiver, the threaded inserts in the receiver might be damaged. Contact Direct Support to correct this condition.

d. If minor loosening of the screws does not result in both the retention of the shim plate, and the ability to remove the shim plate while the plunger is depressed, install one spring washer between the receiver and the right half base. Be sure the screw passes through the hole in the washer to prevent breakage of the washer. If you are still unable to remove the shim plate with your fingers while depressing the plunger, install the second spring washer between the receiver and the left bracket assembly. If you are unable to remove the shim plate with your fingers after installing both washers, the receiver may be undersized and require replacement. Contact Direct Support.

NO TE

Do not use more than two spring washers. This may result in loss of the shim plate. Loss of the shim plate makes the M203A2 non-mission capable. If loss occurs, the shim plate should be replaced as quickly as possible.
