Pressure Regulator Knob increasingly hard to turn

by Jon
(Hatfield, Ma. 01038)

My old Husky 1.5hp 6.5gal compressor's Pressure Regulator knob now is increasingly, over several years, hard to turn.


How to remove the red knob and apply perhaps graphite or other suitable lube to the device?

Regulator knob

Usually they just screw out and off counterclockwise.

But chances are it's mechanically worn out due to cheap metal and or plastic components.

Consider replacing it, or perhaps add a second one after this one, open the sick one all the way and use the second one for what you need.

Regulator knob keeps coming off on model 516-051

by Rick
(livonia)

i have a model 516-051 33 gallon.

When turning the knob to relieve the pressure from the line, I sometimes over turn it and it comes off.

Do I need a new manifold, or can I get a new knob assembly for this?

The regulator is not there to be used as a on-off valve. If you want that, it would be better to add a valve.

Otherwise, the quick connects can be connected and disconnected safely up to at least 150PSI.

You'll have to get the assembly to get the knob, and if you plan to do that, fine. But if it were me, I'd replumb the thing with universal parts.

Husky compressor won't fill vehicle tires

by Dave
(Red Bluff CA)

My compressor is a husky 1000 037 268 26 gal upright with a 1.5 hp motor. It generates 150 psi. When attempting to fill vehicle tires I can only get about 47 lbs in the tire, any tire. I have trailers, a tractor and a van requiring varying pressures. The tank regulator reads 150 and the regulator reads 150 but no air flows above 47 lbs. That being said if I apply the chock to the tire while the moron is running I can in effect ram air into the tire to the desired pressure 80 lbs on the van.

So what's the issue?

No air
by: Bill

One of the things on the page "no air out of hose" talks about how air regulators can fail, and in fact, become a low-flow valve that limits the flow of air into the hose.

Since the flow is slow, even though there is pressure in the tank, it takes forever to get to the air tool - or in your case - air chuck, and that's quite possibly why your compressor, with 150 PSI in the tank, cannot seem to fill a tire.

To clarify there is air out of the hose. As I indicated if I place the air chuck on the valve stem while the tank is filling I can effectively ram air into the tire to 90 or more lbs. however with the motor off and static pressure at 150 lbs nothing goes in above 47 lbs. this has been confirmed by filling a tire that has 30 psi to 47 psi.

Thanks

Husky has no air

Dave, this issue is covered in detail on the troubleshooting page about no air out of the hose.

Please have a look at that page on this site for things to check.

Husky H1503TP compressor air regulator will not hold pressure

My compressor runs fine, and the tank fills with air, but the air regulator nob seems to be "popped out" permanently, and does not deliver air unless I force the red knob down. Even then, I can only get about 40 pounds of pressure delivered out of the hose. I think I need a new regulator assembly, but thought I would ask if you had any other ideas on how to fix the problem.

H1503TP husky air compressor
by: Anonymous

...and the same problem. They Locktight the screw in the red knob so you can't even remove the knob without shearing the screw.

Indeed - a generic $35 dollar regulator (up to 200psi) has to be retrofitted or eBay it

Iam pretty handy (ex-shop teacher), so I was able to dismantle the compressor. It turned out that the threaded shaft of the pressure regulator was stripped. Already ordered a replacement oem part, so I should be up and running soon.
Thanks,

My Richard, this is another one of the mini air compressors made to look pretty by shrouding the working parts so that you, the owner, cannot get at them to easily effect repairs.

From what you have written it does sound as though the regulator is pooched.

You will need to get the shroud off to see what's underneath. It looks like and in-line regulator with a jazzy knob and an external gauge.

If you are handy, then you can remove the regulator that's there, air compressor off and air dumped from tank completely before you start, and then cobble in another general purpose regulator if you cannot find OEM equipment.

Here's one that could work. You wold have to install this one in line where the old one was, and then plumb the gauge port to the existing gauge.

When you are done you may not be able to reattach the shroud, but then, in MHO they are usually a pain, anyway.

Cheers,

Bill
