Clean up your V-pack Act!

Step 1: Check to see if your tank is equipped with the pulse jet system (PJS). Tanks with PJS will have a control unit next to the hydraulic reservoir inside the center hull compartment.

V-packs on PJS-equipped tanks are self-cleaning, but you can clean them under emergency conditions. Follow the procedures in your -10-2 TMs.

Step 2: Before removing non-PJS V-packs, use a black marker or grease pencil to label the filters L, C, and R (left center, and right). That's so you can put the V-packs back into the same slots after you clean them.

If the V-packs are put back in a different sequence, they won't line up with the original compression points on the air plenum box seal. That leaves gaps in the seal and allows dirt to get to the engine.

Step 3: After removing the V-packs, get your mechanic to clean the filters with the V-pack cleaning wand.

If a mechanic or the wand isn't available, clean the V-packs yourself by shaking them gently. Hand-brush dirt and dust from the elements. Never hit the V-packs against anything harder than the heel of your palm. Dented V-packs won't seal out dirt.

Notify your maintenance folks as soon as possible that you had to clean the packs and why. They'll give 'em a proper cleaning and determine if they're serviceable.

Step 4: Wipe any loose dirt or sand out of the bottom of the air plenum box. If you let enough stuff collect there, the V-packs won't seat properly.

Step 5: Reinstall the V-packs. Remember to put them back in the same order that you removed them.
