On this page I will describe in detail how to disassemble, clean, and reassemble the Shocker Sport. It is said that you should re-grease your marker after every day of play. Personally I agree and always do this. This will ensure that it not only functions good, but it will also make sure that no parts of the marker will be damaged from not being used for periods of time between your games. To help you to clean your marker, you should have at least two lint-free cloths nearby (or equal substitute). You will use one to clean with and the other to set parts on. I suppose paper towels or napkins can suffice too, but a cloth is best. And I'm sure that I don't have to remind you to use DOW Corning 33 Shocker Lube with your equipment when it's needed (for a list of other acceptable greases, go here). And of course you're going de-gas any marker before you disassemble it.

These are the things you'll need for a complete overhaul of your Shocker: assorted allen wrenches, Shocker lube, flat-head screw driver, Q-tips, napkins/paper towell/cloth, needle-nose pliers.

Body Assembly

Periodic maintenance should be performed after approximately 25-30 games on a frequently-used marker. The bolt should be removed from the body by rotating the extracting plug item in a clockwise direction until the threads disengage. The bolt can be extracted by pulling this plug. With the bolt in the fully-assembled position, all external o-rings should be examined for possible damage. If any damage is noticeable, the repsective o-ring should be replaced. When replacing, apply a light coat of grease to the o-ring prior to assembly. If no damage is visable, apply a substancial amount of grease to the o-rings. You can also pull the bolt tip forward then apply some grease to the ram section of the piston, the move it back for forth a few times to distribute the grease on the inner o-ring. Also note the two sections of holes in the piston housing. A generous amount of grease should be applied within these holes, then move the bolt tip back and forth to again distribute the grease. The bolt assembly is then ready to be reinserted into the body. Also reinstall the extracting plug by clockwise rotation. This completes the periodic maintenance proceedure of the bolt.

Bolt Maintenance

Overhaul maintenance should be performed on a regular basis, every six months or after completing 100,000 pressurized cycles. To perform this maintenance, remove the bolt by unscrewing the extracting plug from the rear of the body then by pulling the bolt out from the body. In order to examine the inner o-rings and the main part of the piston, you must disassemble the whole bolt. While in it's fully-forward position, heat the bolt at the point where the tip comes in contact with the piston ram. This heat will loosen the loctite between the bolt and the ram, and allow you to unscrew them from one-another. Once they're seperated, apply heat to between the extracing plug and the ram to loosen them apart as well. Once they're seperated you can pull the piston through and out of the assembly. This will complete the disassembly of the bolt assembly.

The following blurry diagram illustrates the firing chamber and fill chamber poppet in their fully-assembled positions within the marker body, and outside the body in an exploded view as well. The firing assembly consists of two sections: a fill section and a firing section, which are interconnected with a floating push rod. This maintenance proceedure is divided into two sections. The first deals with periodic maintenance of the firing mechanism; the second deals with overhaul or major maintenance of the firing mechanism.

Firing Assembly Maintenance

Now you will concentrate on the fill poppet. To disassemble it, use a flat-head screwdriver to remove the plug from the rear of the housing. Once it's out, tip it upside-down and let the contents fall out (don't loose them, though). Three seperate parts and one o-ring should fall out from within the housing. Clean all the surfaces of everything, including the inside of the housing and the inside of the bore in the Shocker's body. Once you are done cleaning the parts, reassemble them as follows: Slide the spring over the poppet, and slide the bearing on behind it (with the o-ring around the bearing). Observe the following diagram from a Shocker Sport:

Fill poppet

Apply a thin coat of grease to the bearing's o-ring, then drop the entire assembly down into the poppet housing as shown in the pic above. Once it's in, screw the guide plug back onto the rear of the housing. Now it's time to clean and re-grease the housing's o-rings. When you're done, reinstall the housing back into the rear of the body. You don't have to put the poppet rod in. Now it's time to clean the fire piston. Housed within the fire piston housing is the actual fire piston part. If you can't take it out by hand, feel free to use a pair of needle-nose pliers. Be very wary of the o-ring around the piston plunger: if you damage it your marker will leak down the barrel. This means you must clasp the very end of the housing but no further, lest you risk damage to the o-ring. Once it's out, clean the inside of the housing with a q-tip, then clean the old grease from the piston and apply a thin coat of new grease to the two o-rings shown in the picture from a Shocker Sport:

Fire piston

Once it's good and greased, you need to slide it back into the housing. It must go in perfectly straight or it will not fit. This can sometimes be tricky, however you'll get the hang of it. You can push it all the way in if you want; it dosen't matter. Now what you need to do is clean the fire piston housing's bore in the front of the Shocker's body. If you can, get down in there and clean the small brass ring. Once you're ready you should clean and re-grease the four enternal o-rings on the housing. When you're done with that, drop the poppet rod back down into the gun and move it around until it slides into the poppet at the other end. Then screw the fire piston housing back into the body. You are now finished cleaning your Shocker! If you think you should, you can now clean your solenoids and/or your Max-Flo regulator.

If your Shocker leaks or otherwise is not functioning properly check the Shocker Sport troubleshooting guide.
