Some come with an aluminum and a stainless steel seat. Always use the stainless steel seat. • Before disassembling the UL88, install a 5/8” spacer between the control arm and the UL88 power chamber body. This will ease disassembly and prevent distortion of the power chamber diaphragm during re-assembly. A 7/16”-16 capscrew head works well as shown. Don’t confuse the correct spacer location with the “T” stop lower on the control arm. The 5/8” spacer should not be placed there. . La correcta reparacion del kit UL88 se muestra en este programa como se muestra en la foto de la izquierda algunos con asiento de aluminio o de acero inoxidable. . Antes de desmontar el UL88 instale un espaciador de 5/8" entre el brazo del control y el cuerpo de la camara de fuerza del UL88. Esto facilita el desmontaje y prevendra la distorcion del diafragma de la camara de fuerza durante su ensamble. Un tornillo de 7/16"-16 funciona bien como se muestra en la fotografia. El espaciador de 5/8 no debe ser reemplazado. 2 UL88 Regulator Repair Tips - 2 Grooves go towards the diaphragm 3 UL88 Regulator Repair Tips - 2 • There are 2 diaphragms in the repair kit. The edges of the diaphragms should have strands of cotton braiding. If not, don’t use them. The thicker diaphragm with the hole in center (shown) goes between the pressure chamber and metering chamber. Install the needle holder through the diaphragm as shown. Then install the washer with grooves towards the diaphragm. Install and torque the retaining nut. Hay dos diafragmas en el kit de reparacion. Los bordes de los diafragmas deben tener filamentos de algodon trensado, Si no los tiene no los use. El diafragma mas grueso con el agujero en el centro (ilustrado) va entre el camara de presion y la de medicion. instale el retenededor de la aguja a travez del diafragma como se muestra entonses instale la arandela con los surcos hacia el diafragma, instale la tuerca y aprietela 3 UL88 Regulator Repair Tips - 3 Metering pin Sharp edge up Sharp edge 4 Rounded edge UL88 Regulator Repair Tips - 3 • The snap ring that holds the metering pin into its holder has a sharp edge and a rounded edge.

The diaphragm is blown because air can leak under the washer and into the hole through the diaphragm. The air passes through the inner layers of the diaphragm and causes it to burst. Muestras de un perno quebrado y un diafragma roto causados por la tuerca del sostenededor del perno floja. El diafragma esta roto por que el aire pudo pasarse por la debajo de la arandela y el agujero a travez del diafragma, el aire pasa por las capas internas del diafragma y lo rompe. 5 UL88 Regulator Repair Tips - 5 SPRING RETAINERS SPRING CHAMBER ADJUSTMENT SCREW 6 UL88 Regulator Repair Tips - 5 • Care should be taken to insure the spring chamber springs are seated in their retainers on both ends when assembling the UL88. See the two upper photos. • Before installing the nose of the UL88 to the main body, back off the spring chamber adjusting screw just enough so the metering pin and the spring chamber springs are all seated and the assembly can be easily held together as shown in the lower photo. . Se debe tener cuidado de asegurar los resortes del compartimiento de resortes estan asentados en sus retenedores en ambos extremos al ensamblar el UL88. vea las dos fotos superiores. . Antes de instalar la nariz en el cuerpo principal del UL88, retroceda el tornillo de ajuste del compartimiento del resorte lo suficiente para que el perno medidor y resorte sobre su asiento del compartimiento del resorte. y el ensamble puede ser efectuado facilmente como lo ilustra en la foto de abajo. 6 UL88 Regulator Repair Tips - 6 Spring chamber adjustment (see previous slide) Control arm Butterfly open stop screw UL88 to butterfly valve linkage with adjustable ball cranks 7 Butterfly closed stop screws.

Then adjust the butterfly valve lever stop screw against the lever. Last adjust the butterfly valve stop (if so equipped). See the next slide for a photo of this stop. • Remove the 5/8” spacer from behind the control arm. The control arm should rest against the UL88 power chamber housing (where the spacer was previously located). Adjust the butterfly-open stop screw against the control arm. • Back off the t-handle compressor regulator on the console. Tight the volume control all the clockwise. Turn the compressor ON/OFF valve OFF. Start the rig. The receiver should build to 150-170 PSI. If the 100 PSI pressure reducing valve was set correctly the butterfly should close at 150 PSI. Turn the compressor ON, the pressure should not increase. Tighten the UL88 spring chamber adjustment just until the butterfly opens, then tighten the jam nut and install the cap nut. • Turning the T-handle regulator should now regulate the pressure. Turn the regulator fully clockwise. If 350 PSI cannot be reached tighten the spring chamber adjustment until it can. Do not exceed 350 PSI. .

    The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
