Nitrogen pressure in accumulators, Active Q

[ScottJackson]

since I'm poor and love to do things myself on my Q, I would like to recharge my accumulators with nitrogen. I wouldn't think it'd be very hard to drill and tap them for an air valve. After that, it's just a matter of filling them with the right amount of nitrogen gas. What I need to know is how much pressure is supposed to be in the accumulators when full. I would either drill and tap them with wheel bearing grease on the bit/tap to prevent getting too much shavings inside the accumulator or I would drill and tap with no grease and wash out the shavings with water and allow them to dry before inserting the air valve and filling with gas. Sound like a plan? where would be the best place to get the nitrogen in a pressure I would need? Welding shop?

Check with texasoil. He provides recharging solutions...

Accumulators are reportedly made to aircraft standards, so probably not a backyard job. Keith Bowers (TexasOil) may inform you, but may not due to possible legal liability issues.

Drop me am email off line. It is not possible for you to modify and recharge the accumulators as easy as you think.1) patent applied for the method and materials for doing it.2) Instructions are copywrited3) Just the high pressure nitrogen regulator costs $600 (no -welding shops do not use/have the right kind)

The high recharging hose cost me $175 in HOSE alone at wholesale price(for 6') it goes by the inch. Fittings are equally expensive.

It's real easy to kill yourself if you do it wrong. The high nitrogen pressure is MUCH more dangerous than high hydraulic pressure since many times more energy is stored.

Even after 4 years of research and development, I still occasionally have 'leaker' which is why I test them 24 hrs at full pressure, use aircraft gas leak detector, etc. Have experimented with precision machining (VERY VERY COSTLY) and not fool proof, high accurracy drilling,tapping, welding (has its own set of problems), and 6 different sealing materials and methods to arrive at current (best so far) process.

MUCH cheaper for you to buy recharged from me than equipping yourself to do it. There simply is no 'commercial' place/shop/service/ that has the stuff needed and the charge pressure specs that work--and I sure as hell am not gonna give them to anyone.

Sounds fair. I had already emailed texasoil and had just got to wondering if it was possible to DIY. From the sounds of this thread, it isn't. Hopefully soon I will have the small amount of cash to get some recharged units from Keith. Thanks y'all

Recharging the accumulators really is not a diy job. It would have been a trivial cost for Infiniti toprovide recharging access valves as OEM.The resulting product has to be able to stand over 5000 psi.
