My KMB-1 M/X has one-shot pneumatic lube. The timer you describe fires the solenoid valve (I've never checked the exact timing) and runs when the servos are activated. The duty cycle is dictated by the profile of the cam on the timer. The oil flow rate can be controlled by the the air pressure to the valve. The lubrication is total loss, that is, the oil ends up in the coolant sump in the base of the the machine. If you have retained the relay card (assuming a similar set up to mine) you could reinstate this arrangement, I've found it simple and reliable.
