Maintenance frequency: This LPR will ideally require infrequent maintenance. Suggested interval is every 10,000-15,000 pressurized cycles, or every 1-2 months (approximately).
These are the things you'll need to disassemble and clean your LPR: assorted allen wrenches (0.05", 1/8"), Shocker lube, Q-tips, napkins/paper towel/cloth.
Disassembly:
To disassembly the LPR, the first step is to unscrew the adjustment endcap from the LPR housing. If you have it locked down, use a 0.05" allen wrench to loosen the lock screws. Unscrew the endcap counterclockwise and remove the spring underneath.
Unscrew the LPR body counterclockwise from its mount (attached to the gun). Once the threads disengage, the small poppet spring inside will push the two apart. Use the microline fitting on top of the LPR body for leverage if necessary.
Grasp the end of the poppet inside the housing and pull the LPR assembly out. Set the housing aside.
Maintenance/Reassembly:
The LPR assembly consists of a poppet screwed into a piston, with a circular base loose around it. Clean the surfaces of all components, and use a q-tip to clean the flared portion of the poppet as well as the opposing surface of the base. This is the key to the LPR sealing and performing its regulating task, so make sure it's good and clean. Re-grease only the o-ring around the piston.
If necessary, the poppet can be unscrewed from the piston using a pair of 1/8" allen wrenches. This allows you easier access to the poppet and base seal, if the parts are excessively dirty. When reassembling, make sure the diagonal face of the base component faces the flared section of the poppet. Apply loctite to the threads of the poppet and screw the two together hand-tight; do not overtighten.
Before reassembly, take the time to clean the inside of the LPR housing with a q-tip, to remove the old grease left from the piston. Re-grease the piston o-ring if you haven't already, then push the LPR assembly into the end and place the poppet spring around the exposed end of the poppet. Screw the housing back onto the mount on your marker, then drop the endcap spring back down into the end of the housing. Screw the adjustment endcap on and allow loctite at least 12 hours to cure if you disassembled the LPR poppet/piston while you had the LPR apart.
