The check valve is cracked and leaking. I have ordered replacement parts twice on line each one of them arrived with wrong threads. I cannot find the manual on line and Harbor Fraight help line cannot find the darn thing. I am frustrated. Can anyone help. I noticed that the threads all seemed to be slightly off for some reason. The copper pipe is just a tad to wide. I had to grind the compression fitting a little bit to make it slide on to the pipe. I think they must have gotten a good deal on all the pieces because they didn’t meet the standard in production. I have to use a lot of Teflon tape on the threads to get them to deal properly. Jb weld might be useful. I also had to replace the pressure switch. It’s almost not worth repairing the compressor unless you are stubborn like me and have to try fixing things before throwing it out. I don’t see anything hard stamped.

If you have a digital format of any Central Pneumatic compressor, please contact me and I’ll arrange to upload it here for others to use. Thank you. Below you will find postings with issues and comments about this brand of air compressors, from folks that use them The majority of issues posted about the Central Pneumatic air compressor line are problems encountered by many brands of compressors and the answer to your questions is likely already there. For example, why air compressors run but don’t build pressure, why they won’t shut off, why they blow breakers, and so on. Thank you in advance, have a great day ! It has given me things to try to resolve my problem, but, my problem remains as follows. This model does not have the pop-up vent on the head. As with many of these, it works fine when charging from empty, but when trying to cut-in during normal use, the motor “struggles”, won’t start, and trips the reset.I have a Harbor Freight 61454 21 Gallon 2.5hp compressor that seems to trip the reset button due to heat (?) It’ll build up to 30-40 lbs then kicks the reset out. The motor is warm, but not too hot (I could be wrong, LOL!) There’s no leaks that I can hear at the pressure switch or check valve. And the thing holds whatever air pressure is in the tank.It did at one time then suddenly stopped. Issues common to all and by the compressor make.

It works very well keeps up with all my air tools even my grinder and air hammer. The only real problem I had was with the seller Creative Online Solutions in their listing they said this product would be sold from and shipped from KY which was the reason I choose them. I was in a time crunch and shipping from KY to PA would only be a few days I had ordered it on a Saturday and needed for the next Saturday. That was not true it was drop shipped from CA and I had to borrow a compressor to do the job I needed because the shipping took far longer than expected. This seller had my negative feedback removed after I called him out for listing that it was shipped from Ky while it was actually drop shipped from CA. I see he has finally fixed the listing after several complaints to Amazon. I have reached out to support about this issue and another and they do not even reply. Remember you get what you pay for and in this case, I get nothing for what I pay for. Please try again later.

One moves 20 lbs in either direction depending on if you tap it or not and the other needle doesn't move at all.

T urn the T ool Pressure Adjuster (2A) counterclockwise to decrease the air output to the tool, down to the minimum rated pressure (0 PSI) as indicated on the T ank Pressure Gauge (3A). T o Empty Air And Condensation From The T ank: 1. The W ater Drain V alve (10A) is located underneath the Air T ank (9A), and should be used daily to release all trapped moisture through this valve. Then, unplug the Air Compressor ’s Power Cord from the electrical outlet. 4. Slowly and carefully unscrew (no more than four threads) the W ater Drain V alve (10A) until the compressed air and condensation begins to be released from the Air T ank (9A). Allow suf?cient time for all of the air and condensation to escape from the Air T ank. Then, ?rmly retighten the W ater Drain V alve. P AGE 8 INSPECTION, MAINTENANCE, AND CLEANING 1. CAUTION: Always disconnect the Air Compressor from its electrical supply source before performing any inspection, maintenance, or cleaning. 2.

If abnorm al nois e or vibra tion occurs, immediately disconnect the Air Compres sor from its electri cal supply source and have the problem corrected before further use. Do not use damaged equipment. 3. DAIL Y: Check the Air Compressor oil level. If necessary, ?ll with a premium quality, 30-weight, non-detergent compressor oil. NOTE: When checki ng the oil level, make sure to unscrew (do not pull) the Breather V alve (14B). 4. DAIL Y: Purge the Air T ank (9A) of all air and moisture to prevent corrosion. T o do so, slowly and carefully unscrew (no more than four threads) the W ater Drain V alve (10A) until the compressed air and condensation begins to be released from the Air T ank. Then, ?

rmly retighten the W ater Drain V alve. 5. EVER Y 100 HOURS OF USE: Clea n the Air Filter (7A) with a mil d solve nt. Then, dry and reattach the Air Filter. NOTE: Replace the Air Filter if it is too dirty to properly clean. 6. EVER Y 500 HOURS OR 12 MONTHS: Replace the old oil with new, premium quality, 30-weight, non-detergent compressor oil. 7. TO CLEAN: wipe with a damp cloth, using a mild detergent or mild solvent. 8. WHEN STORING: Keep the Air Compressor in a clean, dry location.If this occurs, shut off the pressure switch and wait at least 5 minutes. Release the air pressure in the tank to ease restarting.

I guess I'll need to buy new gauges.Please try again later. Please try again later.With very little use Ive already replaced the reed valves twice due to breaking and the motor has a hard time turning the compressor from a dead start which trips the circuit protector on the compressor. There are better options for the same moneyPlease try again later. Please try again later. Kevin Shepard 1.0 out of 5 stars Due to going thru cancer treatment, I am just getting around to unboxing the compressor. I used the instructions that came with the unit to get it setup. Once it was turned on, I noticed that the tank would not fill with any pressure. Over a couple of days trying to start it and troubleshoot, and checking for air leaks (5 run times) I didn't find anything. At this point I am stuck at the assembly instructions in the owners manual for the 30 minute break in. No air is being pumped out, but I let it run for about 10-15 minutes. When I shut it off, I noticed that oil was running down the side of the tank. It looks to be misting out between the motor and the regulator. I have added 2 pics where the oil is collecting and dripping from. Looking to get repair parts or return for replacement. Still no response on this. Michaelsons?Please try again later.

This line of compressors is entry level. I don’t believe they are made for serious compressed air use, where whether or not a compressor works means that trades persons do or don’t do work that day.

I just wouldn’t put the supply of my plants air system at the mercy of this particular brand. Their entire line is similar or identical to compressors of other brands with different colors and different labels. I could be wrong and will be happy to indicate so if someone can provide proof that HF actually makes their own compressors. Aside from pressure switches, gauges, regulators, PRV’s and check valves (all the same as those found on many other brands) there are very few repair parts for the compressor pump or the motor. Parts from other Central Pneumatic air compressors can often be used on other models of this brand. If you can scrounge or buy a non-working compressor, some parts from the old can be reused to fix others that have failed. Depends on your skill level as to whether or not this works for you. Include the model number of your compressor.I understand that I can unsubscribe at any time. I since then have gotten the compressor running although it will only occasionally build pressure, and even then it only gets to about 20 PSI. I took the top of the cylinder off and the small metal plates now refuse to stay in place. Is there something else I need to do to get it back working or should I just replace the compressor with another that I have? Someone told me it might be the pressure sensor, but want another opinion form someone that may know from experience. Also if it is the pressure sensor or something else, where can I buy the right part? When it starts again, it runs very slowly until it eventually trips again. Sometimes it will run normally and stay running at the normal higher rate of speed and then eventually return to the slow speed until it is stopped by whatever it is that is tripping the reset. Any ideas as to which direction to look to solve this problem? Tank check valve seems ok ( no visible signs to indicate faulty and no air leaks from anywhere when tank pressurized). What else could it be. Thanks in advance.

Also the cold start valve went out as they ALL DO ! A few weeks ago it would not shut off at the high pressure level approximately 150PSI. The PVR goes off and the motor does not shut down. I ordered a new switch thru Amazon. It arrived yesterday after a week delay and got it installed. Nothing has changed. Any suggestions. I did the math from the HF manual and installed 4.5? pulley on electric motor. I just started to build the air compressor a week ago June 10,2020 the parts have been in my garage shrink wraped until I needed them. I have a HD 60 gallon tank. The pump gets close to 25 psi and slows to trip the electric motor if I dont throw the on off switch. I have changed the start capacitor and run assist capacitor with no change. Checked the reed valves were all good and put new gaskets on the valve plate and head.i changed out 2 different pressure switches and 2 capacitors. I am out out ideas and watched videos asked people at HP and everone tells me to change the parts I have changed please can some one help me. Central pneumatic. I am looking for the regulator for this compressor model 60637. Any help. It runs and builds pressure but does not hold pressure. New hose and fittings. Still does not hold for very long. And it is taking along time to build pressure. Less than 2 months old. The reset keeps popping when its time to fill. Start of day. Motor not hot. Tries to start then pops. Any ideas? Also where would I get the same motor or one that works better yet is compatible to this compressor Model: 61454 21 gallon 125 psi I let it sit outside forgetting it was there and didn’t change the oil. I ran it for about a year here and there doing small stuff but this week I turned it on and heard a snap and the motor went to running super smoothe. The connecting rod broke. I can’t find one. I’ve emailed hf and no answer yet. I’d like to fix it if it’s available. Its been a great small compressor. Thanks for your input How do i find a model number.

Can you help The second picture where am I holding it with my hand is the stock one Compressor model 61454 2.5 hp 21 gallon Hasn’t been used much at all. Model 61454 21 gallon 2.5 hp pressure switch 125 psi Any help on part numbers or where to find parts. Thank You! Is it available or can you recommend a generic I can get a few parts out of. Parts and orings just under the knob. Thanks I stepped on the manifold coking to the tool side of the regulator and the manifold is broken in two places. Any suggestions for where I can purchase a new manifold that would fit. Compressor, gauges and regulator all work great. Thanks I live in South Louisiana! I need replacement. Where in the world can you find one. Searched the web. Going to visit my HF in the morning. Thanks! I have to keep it held up while I pull the plug. It will stay up when the compressor is not running. I’m guessing I need to just replace the switch, Anything else I should check before doing that? Am I missing something obvious? I contacted Harbor Freight and they don’t sell them. So my questions is will these fit my air compressor? Back up to 105psi, shuts off and bleeds very rapidly down to 50psi and starts running again. I just replaced the pressure valve with a like one — seems to be doing the same thing. Ideas? It looks to me like the screws have a round head rather than a hex head which makes no sense, except if this is a way to keep owners from servicing their unit. The compressor is about a year old, and has about 5 hours of use on it. Any information on this will be welcome. Used to work fine. Can’t find one anywhere. The adjusting knob is stripped. Compression rings and oil rings and gaskets. It wont cut off after reaching pressure. Tried the reset switch and got nothing. Is all hope lost? Thank you Can I get some ideas on what to troubleshoot that could be the problem for this compressor. My dad does have the original manual and I called the customer service number but they were not very helpful.

Tried taking to a repair shop and were informed they do not work on Harbor Freight compressors I then noticed it would not fill at all. Any chance in finding a new one? The 5th time, I noticed that the compressor ran for a longer time than normal. I could feel the air being by-passed out the relief valve. WOW, found two of them stripped.Thanks Central Pneumatic. I replaced it. Still didn’t work. After checking things I found on the internet about it, plus taking the head off and checking reed valves, it still wouldn’t work. I removed the air filter and the start valve popped out and started filling with air. I replaced the whole filter unit. Works great! It is a couple of years old. About 2 weeks ago, I noticed that it would not pressurize past 75 psi. It then dropped to max of 50 psi a week later, and now it won’t go past 25 psi. Any suggestions? Do these compressors have a serial number on them or is it just the model number? Does not build up pressure into tank. Pressure directly out of crankcase. What do you think problem can be??? Neither air gauge (tank or outlet) is registering any pressure. If I pull the relief valve there is air pressure. Also air is released when the drain valve is opened. There is no pressure using the air hose and attachment. Tried other tools with same weak response. I am in need of a pressure switch and I called for a replacement and was told they do not make replacement parts for this compressor. Does anyone know of a compatible pressure switch for this model? I am sure I can get the brass fittings and I have the gauges, just the regulator piece to control pressure would have to be added can you assist me on finding the right one? I’ve been to several places that sell compressor parts and was told that harbor freight does not share information about their products. I also checked with a couple of harbor freight to see if can get a part number or someone point me in the right direction and no one could.
