Unloader Problem


#1

My unloader will not go into bypass mode. Has anyone had experience with this? If so, What is the fix?

Thanks in advance.

#2

Try tapping with mallet, pull stem lubricate vanes or if over a year or so replace…


#3

Replace o ring on shutter valve


#4

Flow activated or trapped pressure ?


#5

Unloaders are disposable. If mine give me the least bit of trouble I throw on a new one and it’s good to go in 15 minutes.

I kinda felt like William saying that lol. I’ve honestly never took the time to deal with trying to fix an unloader. I feel like I would just waist time and I can’t afford to do that. You should always keep a spare unloader and get you a pressure gauge from Bob with qc’s so you can set your unloader and be good to go.

I keep shudder rings because it’s a quick fix to try before taking the unloader off. Definitely keep spare unloaders on the trucks. I’ve made it two decades in business without a pressure gauge :grin:

Yea you can set it pretty accurate without one just by looking at the bypass. I’m ocd though I like to see the numbers on the pressure gauge or it will always be on my mind.
