Hello Ni...

By everywhere, I expect you mean Harbor Freight too? If not here is their customer service number: (800) 444–3353 Monday thru Friday, 6:00 am – 9:00 pm PST.

One visitor to this site talked about making his own reed valves out of the spring steel in his paint scraper blade. Had the same problem as you in finding parts.

See the section on the Sitemap page, under general information, for visitor suggestions about replacing gaskets.

Save your time and money lose hb
by: Hate harbor freight

Bought a used harbor Freight compressor. Reeds were bad.

Hb only sells the whole reed plate assembly. Bought two and gaskets. When they came all the contents of the package were loose. One of the head gaskets were ripped. Made new ones out of cereal box cardboard. Installed all of it worked like a charm for about 6months.

Reeds went out.

Used the old not broken reeds to fix it and it lasted another 7 months and the reeds are broke again.

Both time the right side reeds.

Hate harbor freight. Ill just save a bit more and get the good stuff.

Found the perfect springs for making the valve on Ebay..

4PCS .015 Polished Blued Steel 2 Feet Spring Stock Tattoo Machine Custom Parts

7-8 bucks and they are perfect and enough to make at least 8 or more

Compressor reeds can be made easily
by: Bill

Thanks for this. You and others like you have solved the problem for a lot of folks that haven't been able to find or buy OEM reeds for their air compressors.

Make your own! Indeed. Well done.

compressor reeds can be made easily
by: Anonymous

my sons compressor reed broke . harbor freight model. rather than try to order I decided to make the reed out of a .010 feeler gage blade. I tested the bend pressure with a gram gage and the .010 was the same as the feeler gage. I traced the outline of good reed onto feeler gage blade and using a one inch belt sander I shaped a new reed. took 5 minutes. I measured reed and it is next to perfect size. The spring in the feeler gage should work.

Ready to install.

I didnt want to wait or try and get it from Harbor Freight so went to Home depot and got a Hyde 1.5 inch flexible scrapper , they come in 2 thicknesses a super thin flexible and a thin, got the super thin for $5 drew a patern on it and held it by the handle and used my bench grinder to mold it into shape , only took about 10 minutes to drill holes and grind down!

I went down to my local Harbor Freight and noticed that the current compressor motor that they currently (#67698) sell looked very much like the 93786 and you can get that manual on the HF website which includes the IPB etc.

On page one is the phone # you call for parts.

Just on a whim I decided to put 67698 parts in a 93786 because I was sure they would be the same parts and they where. I only had one broken reed valve but decided to replace all of them in both cylinders. Of course get new gaskets also!!!

One thing, when you get your parts you will notice the long Valve Plate or long Reed Valve #17 in the 67698 in (is?) perfectly flat when you receive it and the one in your compressor is bent slightly. You HAVE to put that bend in the new one to keep the Reed Valve flat when it is installed. Just put it in your vice and it only requires very little pressure to get the correct bend, took me 10 seconds.

My 93786 is working great now!! The total for the parts and shipping was about $25.00
Good Luck


Thanks Ron, B.

Model 38898 will only pump up to 60 PSI?

by Harry
(Washington, IN )

Central Pneumatic air Compressor # 38898 - only pump up. 60 lb. - will not shut down

I have had This Air Compressor for about 5 Years, It only has about 10 hours of running time on it.

Worked Great until today, now It will only Pump up to Apox. 60 lb. and will not shut down until you turn it off at the Switch.

What may be wrong ?
Harry, if the pressure in the tank won't reach the cut out pressure setting of the pressure switch, then your compressor will keep running until it goes off on motor thermal overload, or the compressor fails electrically or mechanically.

There a number of issues that relate to this problem, and all are covered on this site.

The first check I always do is to pull off the intake filter, and while the compressor is running, feel the intake port to be sure that the compressor is actually pulling in air. This simple test will diagnose an intake valve problem if the air intake flow is very low, or if air is huffing back out of this port.

Then, if you visit the troubleshooting page (link on the nav bar) and follow the Will not build pressure link you can review it to see if any of the issues noted there are reflected on your air compressor.

If you have more specific questions about what you found, please post them as a comment here so I can follow the thread.

Will not shut off?

by Joe G Rodriguez
(San Antonio, TX USA)

I have a Central Pneumatic 2HP 8 Gal, Item No 40400. The unit will not shut off the pressure gets into the red. I have to turn it off. What can I do.



Bill says...

Hello Joe. If you click the TROUBLESHOOTING link from the nav bar, you'll find a menu with "will not shut off" as part of the offerings. More info there about your issue.

From the sounds of it though I suspect that your pressure switch has failed as this is the device that turns your air compressor on and off, based on the pressure in the tank.

Use my Central Pneumatic compressor as a boat anchor?

by Don B
(Marshall, Tx.)

Compressor threw rod. Would it be worth trying to fix?
Don, If it's oil lubed, and you clean out all the oil, probably better value as the boat anchor than trying to fix it. :-) Probably have to put holes in the tank as well.

However, I don't know what Central Pneumatic air compressor yours is, or what you paid for it, so, ultimately, it's your call.

The repair depot charges what... $75 / hour for work plus parts. Bet on at least one hour plus parts and taxes... you can do the math.

Cheers, and thanks for the chuckle.
