How to Disassemble and Oil Your Tippmann 98 Custom

Paintball continues to grow in popularity, and so grows the use of the Tippmann 98 Custom. It's one of the most commonly used paintball guns, but very few of the owners take proper care of it. This is an easy-to-follow guide explaining how to disassemble and oil your Tippmann 98 Custom.


  1. 1
    Place the gun on a table or flat surface, bolt handle-side up (the bolt handle is the small rod you pull back to cock the gun).
  2. 2
    Turn the velocity adjustment screw all the way in (clockwise). This is located between "TIPPMANN" and "98" in the middle of the gun.
  3. 3
    Remove the adapter bolts (the two bolts holding, to the bottom of the grip, the piece that connects your CO2/air source.
  4. 4
    Remove the six bolts holding the two halves of the gun together: one at the top, front of the gun near the front sight, one at the center of the front hand grip, one in front of the trigger guard, one at the bottom of the rear hand grip, one on the rear sight, and one below, slightly to the left of the rear sight.
  5. 5
    Carefully remove the top half of the gun. If it is not removed carefully, internal pieces of the gun could be knocked out of place.
  6. 6
    Using a soft fabric, wipe away any dirt or other substances that may be found on the front/rear bolt, or elsewhere inside your gun.
  7. 7
    Locate the two O-rings, one on the front bolt, one on the rear bolt. Using any standard paintball gun oil, place a few drops on them both.
  8. 8
    Carefully replace the top half of the gun without knocking loose any internal pieces.
  9. 9
    Screw all six bolts back into place firmly. Screw the adapter back into place at the bottom of the rear grip.


  • All bolts can be removed with the Allen wrenches included with your paintball gun.
  • Oil the O-rings no less than twice per year. If the gun is used frequently (once or more per week), oil them every month.


  • Make sure the CO2/compressed air tank is NOT connected to your gun!!
  • Remove the barrel and hopper (piece that holds the paintballs) before disassembly.
