I can’t get my 90 degree elbow valve off so I can replace the check valve. How did did you get it off and back on.
@@papergatorzfedducca7998 i just used a line wrench carefully as to not crack the fitting or the new valve.
@@hcr-motorworks ok thank you. The 90 degree valve is keep me from getting my wrench, vice grips etc on the check valve. I’ll figure it out.
if you found a piece of metal in your check valve ...question is ...where did it come from? shouldn't you investigate the pump?
It was a sliver from the compression fitting on the tube that fed the valve.
*This does exactly what I was wanting **MyBest.Tools** Price was fantastic, lower than Harbor Freight-and it included hose and attachments, and IT IS MADE IN AMERICA, unlike Harbor Freight*
Can the check valve cause the compressor to not reach full preasure ?
It can, but it could also be a leak at the unloader valve, the pipe feeding the valves or tank or a weak and worn out pump. Just depends
hi thanks. why you dont add teflon to the compression fitting side? and why do you call it compression fitting side where the other side is not? how can i decide which fittings should or should not have teflon. thanks
The compression fitting side has a ferrule or a flared fitting just depending on what setup you have on your compressor. These style of fittings NEVER get Teflon or any type of sealant as the ferrule or flare does the sealing. The other side is Usually NPT or pipe thread and does require some type of teflon or thread sealer to create an air tight seal. Thanks for watching!
@@hcr-motorworks thank you so much. now i get it.
1/4 check valve how mach.
What if there is no case over the plastic puck? Is it normal for some valves or did it just fall off? Does that ruin the valve?
What do you mean by case over the plastic puck?
@@hcr-motorworks the metal cylindrical case at the bottom with holes around it. There is no metal case. It's just a spring and the plastic piece.
@@velvetypotato711 The replacement should be similar to the one pictured in this video. unless they've updated the design or something it should be there. but as long as it seals when the air compressor shuts off and doesn't leak out all the air it should function in the same fashion.
Does it come with the port plug?
It should come with the elbow but if not here's a link to the 90 elbow needed for the unloader valve port amzn.to/3LBob5Y
Does this pump/motor go clockwise or counter clockwise?
Depends on which way you look it or have it oriented...the pump pulley has "fins" for cooling the pump motor and they should always blow towards the pump. Most of the motors themselves are reversible.
@HCR - Motor Works yes, I have the same compressor and had to buy a new motor it can be wired both CW and CCW, so I was wondering which way yours went.
@@theweekendwarrior6355 Clockwise if you have yours oriented in the same way mine is in the video. Pulleys behind the pump.
What did you retorque it to?
Good question, With NPT threads and brass fittings I usually set my torque wrench to about 25ft-lbs just to assure that I wont crack the fitting from over tightening. With 2-3 wraps of Teflon it "SHOULD" tighten and be leak free with 25ft-lbs or less...So in this case, the torque wrench isn't necessary for setting the torque to spec per say, but more so, making sure we don't damage our brand new valve from over tightening. I tighten until tight, and then keep tightening until the valve is in the final alignment with where it should be so the contractor pipe connects with ease. They should be close as far as reaching 25ft lbs, when the valve tightens, and how much further you have to go to get the pipe to align. If they aren't close then remove the valve and add or subtract Teflon tape. For instance, if you did two turns of tape, got everything aligned and it leaked it obviously needs more tape. If you did 4 turns and it hit 25ft-lbs with 3/4 of a turn to go until the contactor pipe will align its got too much tape and is binding before it should. Hope that helps! Thanks for watching!
That is a helpful answer, ive gotta reconnect a new pressure gauge as well as a new pressure switch, thanks again
Anytime, I had to replace both on my compressor within weeks of each other so I feel your pain. Good Luck!
I buying one check valve for air compressor 1/4
Ordered it .
But bottom check valve seems to be smaller ? Is that normal
As long at the threads are 1/2" NPT on the valve and your tank it should work no problem. The dimensions on length of the value are typically not an issue.
@@hcr-motorworks awesome , now i ran into another issue . I didnt get the new elbow .
How did you get your new one?
@@HuizachiiCity1 This one should fit.
1/8npt to 1/4" compression elbow
amzn.to/3ZAZbRw
What was the size elbow coming off the check valve?
This one should fit.
1/8npt to 1/4" compression elbow
amzn.to/3ZAZbRw
Title is misleading. You did not repair the air compressor check valve, you REPLACED the air compressor check valve with a brand new unit purchased from Amazon.
Actually he did repair it. He removed a sliver of metal from a compression fitting that was keeping it from working. Just didn't reuse it
