Replacing Steam and Hot Water Valve Pin O-Rings
➡
vimeo.com/20114980 (password: prebrewpressure)
When the steam actuator is moved into the “on” position, it pushes a brass pin into
the steam valve, which causes the valve to open and allows steam to flow. The two
(2) o-rings on the steam valve pin should be replaced every 12-18 months.
Parts and tools:
•
Replacement steam/hot water valve pin o-rings (part #46000-53090)
•
Phillips-head screwdriver
•
Flat-head screwdriver
•
9/16” socket wrench
•
Pliers
•
Pick or awl
Procedure:
1. While holding the corresponding nut on the machine’s interior with a
9/16” socket wrench, use a flat-head screwdriver to loosen and remove
one of the shoulder bolts and the corresponding steam actuator hub or
hot water actuator hub.
2. Use pliers to remove the valve pin (#7).
3. Use a pick or awl to remove the o-rings from the valve pin and discard
them; install new o-rings.
4. Rub Slayer lubricant on the pin and return the pin to its valve.
5. Reattach the actuator hub and shoulder bolt, tightening with a 9/16”
socket wrench and flat-head screwdriver.
‣
Skip this step if proceeding to other preventative maintenance tasks.
6. Repeat steps 1-5 with the other actuator hub, steam or hot water.
