Ion Infrequent Maintenance [ZDSPB Tech]

Ion Infrequent maintenance
This page compromises maintenance processes that don't need to be performaed very often. Details vary depending on the part.

SFT O-ring:
The SFT o-ring is located inside the Ion breech section, right in front of the barrel. This o-ring seals against the bolt during firing.

The SFT o-ring can be the cause for paint breaking issues, especially during the winter. If necessary, remove the o-ring using a curved or bent dental pick, and replace with a clean, new 17/90 o-ring. If you chop a ball in the chamber then paint will most likely work it's way around the o-ring, in which case replacement is recommended.

To remove the SFT o-ring for replacement, you'll have to use a curved or angled dental pick. The one I use has a small crease right at the end, which makes it ideal for pulling o-rings from their grooves. Dig the end of the pick down into the o-ring groove (between the ring and the groove wall; don't just spear the o-ring with the pick...this won't work), then twist the pick around to get under the o-ring. This can be accomplished in front or behind the o-ring, depending on the shape of the pick. Once the pick is under the o-ring it will be easy to remove it.

Swivel Donut:
The swivel donut can remain assembled on the fire chamber indefinitely, as long as there's no leaks. If there is a leak coming from either side of the donut, or if you wish to remove it to replace the o-rings otherwise, here is how to do it. The first thing you will need is a snap clip removal (aka. c-clip remover). You might be able to get it off using needlenose pliers, picks, or other tools, but it will be difficult. Obviously, if you are attempting to remove the donut and scratch up its end, or the fire chamber, that's okay (no hard will come of a scratched part).

Once the c-clip is out of the way, the donut will slide off the back and reveal two 15/70 o-rings underneath.

Internal Hoses and Fittings:
No actual maintenance is required for the internal hoses, however some of them are sealed with o-rings (such as the microline fittings, and the solenoid head barbs). Leaks from those locations are often the result of the respective o-ring located there. For more information on this, refer to the solenoid and internal hoses page in the Related Links section.
Removal of the solenoid head barbs is accomplished by using a small pair of pliers and unscrewing the fittings. They are loctited into place from the factory so this may require an amount of torque the first time. After the fitting is removed the sealing o-ring will be visible.

When reinstalling, use a very SMALL amount of thread locker on the threads.

After a period of use, a yellowish film will become visible on the hose ends that are inserted into a microline fitting/banjo (only noticeable on clear hoses, obviously). This is just a sign of slight moisture inside the marker and isn't anything to worry about.
