Changed my air governor today

is it (pissing) constantly? you can adjust the pressure on the air governor unless it is a sealed one. take rubber cover off and loosen lock nut and adjust accordingly. if the dryer is acting up the spitter valve is probably getting weak. can get a spitter valve replaced and air dryer filter replaced. but some times it is easier and cheaper to just replace the whole dryer.

 

Adjust the governor so your max pressure is about 120 PSI. If the dryer is leaking out the exhaust all the time you can do the valve buy my experience with that has not been good. I prefer to install a new unit and be done with it. Filter should be changed yearly and if you are showing oil at the exhaust it might be time for a compressor too. My 2 cents.

 

Change your purge valve.

Check the price of the valve against the cost of a new air dryer. It might be worth it to replace the whole air dryer. I got an air dryer replaced in a TA shop for a '98 International for around $150 plus labor.

 

if governor has blue cap on the bottom, it is the newer type & cannot be adjusted. this type does build up more pressure than the older ones. I use them. I like them better,

 

Not to mention there are different rated PSI's for governors. I haev always been asked which one I want when buying them at Detroit etc.

Technically, yes. What this means is that the compressor is running all the time, which would increase the wear on the compressor components. In actuality, probably not, because the compressor is made to run.

Vague, I know. I had this issue once. The biggest problem I had was from a driver parked next to me at a truck stop that was pissed that I parked next to him with the air dryer purging every minute. I moved, but I did let him know that if he couldn't sleep in a noisy truck stop that he probably needed to find somewhere else to park, or reconsider his career choice.
