bomb recharge procedure???

[Mike Arman <armanmik@n-jcenter.com>]

Let's think about the bomb for a moment: Essentially it is a metal sphere
with a rubber diaphragm in the middle. One side has pentosin in it, the
other has nitrogen at 2,000 psi or so. Failure mode is that after a few
years the nitrogen diffuses through the diaphragm, and pressure assist is
lost. The diaphragm itself MAY not be torn or defective, and if there were
a way to replace (recharge) the nitrogen, the bomb would be OK again (per
Citroen "recharge" comments earlier).

Oh, how I would like to see the following procedure:

Bomb recharge, first time:

	1. Release pressure in bomb by pumping brake pedal as needed.

	2. Remove bomb from car, clean well.

	3. Drill 1/4" hole at location X, screw/braze/otherwise attach high
pressure schrader (tire valve) fitting in place.

	4. Charge bomb to 2,000 psi, close valve/screw/whatever.

	5. Reinstall bomb, bleed pentosin, drive away.

	(charge to modify and recharge your bomb $75.00, exchange, $100 core
charge, subsequent recharges, $15.00, usual verbiage and disclaimers)

Bomb recharge, subsequent times:

	1. same as 1, above.

	2. Without removing bomb from car (Novel idea, that! Especially for an
Audi!) attach pressure hose, charge to 2,000 psi, close valve, drive away.

The keys here seem to be the installation of a valve to replace the
nitrogen, and the procedures for handling 2,000 psi nitrogen. The valve
would have to be installed in such a way that the diaphragm would not be
damaged, and in such a position that the valve could be accessed without
removing the bomb from the car. Handling nitrogen at 2,000 psi is not a
major problem - think welding tanks. Nitrogen in tanks is available from
the local industrial gasses supplier or welding shops, this CAN'T be that
difficult!!!

Food for thought?????????
