Does Anyone Know The Pressure On The Hydraulic System That Operates The Top?

I AM JUST COURIOUS DOES ANYONE KNOW THE PRESSURE THE HYDRAULIC SYSTEM OPERATES ON THAT WORKS THE TOP? AND ANY IDEAS ON HOW TO BLEED THE SYSTEM AFTER A BROKEN LINE?

THANKS, DENNIS

The manual says the motor can get over 2,200 psi.
Read the manual for details. Section 23 page 514
If you have not downloaded the manual you can get it from here. Look at the 2005 manual. https://www.crossfireforum.org/forum...tml#post111722

The Hydraulic Pump (2) is driven by a reversible permanent-magnet motor (3) that makes use of the magnetic field
of the magnets to convert electrical energy to mechanical energy. The pump motor (3) is capable of delivering over
150 bar (2200 psi) of pressure to move the hydraulic cylinders. The pump motor is controlled by the Power Top
Control Module (PTCM) which is mounted to the power top hydraulic assembly mounting bracket. Battery voltage is
supplied to the pump motor (3) from Fuse 6 (40A) located in the Underhood Accessory Fuse Block to both Left and
Right Rotation Relays. The PTCM monitors the power top switch signal, when it senses a signal from the switch;
the PTCM controls the battery feed and ground to the pump motor (3) through the rotation relays. The pump motor
(3) has two pressure relief valves (one for each direction) located in the pump housing (2) that dumps the fluid back
into the reservoir (1) if the hydraulic pressure raises to a dangerous level. The right rotation pressure relief valve is

set at 115 bar +/- 10 bar
