I’ve had several CD-1 owners contact me about the hydraulic system that came with the digger. It was a self contained system that consisted of a pump, valve and reservoir.
I’ve not been able to determine very much information about this system. According to literature supplied by Danuser, the pump supplies 1500 psi at 2 1/4 gpm. Information on the pump indicates that it was supplied by Cessna. The only identification I’ve been able to find on the pump is 8 04 RT. If any one can supply me more information, I would be very appreciative.
The parts break down for the pump looks like this:

I found this information about Cessna on the internet:
Cessna Hydraulics was acquired by Eaton Hydraulics in 1988. Eaton continues to manufacture the Cessna line of pumps and motors.
