TM 10-1670-296-20&P 0020 00
Inspect and repair the parachute connectors (14) and the timer delay assembly (6) as described in
the REPAIR TIMER DELAY ASSEMBLY, TOGGLE AND KEYS paragraph and WP 0023 00.
2. Clean components.
Clean each component, except the arming wire, using procedures in WP 0008 00. Clean the arming
wire only by wiping it with a soft, dry cloth.
If necessary, remove dirt and debris from inaccessible locations using a compressed air hose.
3. Repair timer delay assembly, toggle and keys.
Remove the four screws that hold the back cover of the delay assembly. Carefully remove cover,
toggle, and keys from the housing.
Thoroughly brush foreign material away from the toggle and keys and from the surfaces from which
the toggle keys were removed. If the parts are rusty, corroded, pitted, or signs of marks are present
where the toggle has rubbed up against the channel in which the keys slide, replace the delay
assembly, toggle or keys with a serviceable one from stock.
Do not use steel wool or a wire brush to clean, as these will damage the
permanent dry film lubricant that was applied to the key-way surfaces
when they were manufactured.
