Motor Bracket BA018300AV

Remove the motor bracket then remove the pump and motor assembly. Remove the four bolts that hold the head, gaskets, valve plate and place them all in the order that you removed them. Unscrew the piston assembly and remove the piston and cylinder. Install the new piston with the cylinder. Place all of the gaskets valve plat, etc back on the cylinder head, then Install the four bolts that hold it all together. I also replaced the motor bracket and the isolator pad.

fixed it

Unplugged the compressor. Removed the old pressure switch and the broken bracket. Successfully installed both by using a phone camera (to get a picture of wiring) and tools listed above. All works well!

The motor bracket I ordered had to be replaced. When it broke for sometime, this let the motor rotate back and copper tube I ordered had to be replaced due to rubbing against the back. As you stated in the instructions the copper tube had to be cut to fit. With a tube cutter I cut the tube to right size and installed the tube with hardware I ordered and everything works fine (no leaks). I'm glad I founded your Web site, I have had this Campbell Hausfeld Compressor for quite a few years Thanks for your support Gene S.

I received a used air compressor from a friend. He said his neighbor was throwing it away and he thought I could at least use the tank or other items off it for spare parts. Once I got it home, I plugged it in to see if it would run at all and if there may be a way to fix it. It ran fine but wouldn't build pressure above 20psi. I thought for sure it would need a pump rebuild which would be expensive. I visited the ereplacementparts.com website and after entering the compressor information, I was able to see what the common cause of the symptoms were, to this specific compressor. I learned that a great percentage of the time the cause was a broken fill tube. I took the removed the plastic cover off the compressor and sure enough, the tube had a crack in it! Talk about a cost and time saver.
The reason, I started the directions with telling you this story is to illustrate how valuable this website's ability to help diagnose or at least help you narrow the causes, is! So, now with the help of EREPLACEMENTPARTS.COM and about $30, I have a $300+ air compressor!!
Okay, enough of the accolades and on with the steps:

SAFETY FIRST!!! Make sure the switch on the compressor is off and that it is unplugged from the wall socket. If it's hardwired into your power supply, shut off the breaker and tag it out.

1) Remove the female quick-connect outlet (the connector you plug your air hose into) using a 13/16" open- end wrench. This will allow you access to one of the cowling screws.
2) Using a Phillip's head screwdriver remove 2 screws holding down the top part of the plastic cowling covering the pump and motor.
3) This part may be optional, but I removed the bottom cowling using a 3/8" socket with extension. I also removed the intake muffler/filter/baffle and set it aside. I like lots of room to work.
4) In my case, the motor bracket was broken so I had to remove it using a flat head screwdriver. I believe you can also use a 5/16" wrench or nut driver. I removed the bolt that secures the pump to the frame, using a 3/8" socket wrench. This allows you some 'wiggle" room to install the Air Tube.
5) Remove both of the brass compression nuts that secure the Air Tube to the pump and check valve using either a 11/16", 3/4" or 13/16" (I can't remember exactly which one was used and I'm not going to disassemble my compressor just to check! LOL. I'm pretty sure it was 3/4". If you don't have all three, carefully use a large crescent wrench.
6) Carefully remove the old Air tube, preferably intact. Compare it to the new one and if the new one is larger, use a scribe or permanent marker to mark which end is longer than the original.
NOTE: It's okay to be generous in leaving a little extra on the new tube when marking it. You'd rather leave a little too much and have to trim or cut it again, rather than cut it too short and have to order another one. If you removed or loosened the motor bracket bolts it will easily allow you to install a tube that's a little longer and make it much easier to install the tube all together.
7) Cut the new Air tube using a tubing cutter. If you don't have one you can buy one online or at your local auto-parts or hardware store for around $10. If you haven't used one before, you can practice on the old tubing after measurements are made. You can also use a high speed cut off tool or hack saw but using those tools and getting a clean, 90 degree cut can be difficult. For me the tubing cutter is much easier and provides a clean, 90 degree cut.
8) Without the nuts or rubber seals, temporarily install the tubing for fitment and trim again if necessary.
9) Next clean the threads on the pump and check valve where the new tubing will be installed. Be careful not to allow any debris to get in the pump or the check valve. Also if the check valve has a screen to catch any debris, make sure it is clean and free of any oxidation. Make sure the new tube is free of any internal debris.
10) Put the compression nuts on the new tube (Back to back) and then slide the rubber seals on. Put the tubing in place, wiggle the tube to make sure it seats on both ends and finger tighten the compression nuts.
11) Reinstall the motor bracket and finger tighten the screw as well as the bolt that secures the pump to the frame. Because air compressors vibrate, a lot, I applied blue thread lock before installing this screw and bolt.
12) Now, tighten the compression nuts to the point where the rubber seal just starts to squeeze through the back side of the compression nuts. Don't tighten any further, you'll break or strip something. This is enough to provide a good seal.
13) Tighten up the motor bracket screw and pump bolt.
14) Re-install the lower and upper cowling and the corresponding screws and bolts. Apply Blue Thread-Lock.
15) Clean the threads on the female quick connector's threads, apply new Teflon tape and reinstall.
16) Plug in the air compressor, turn it on, allow it to build a little pressure, shut it off and listen for leaks. If there are no leaks, turn it back on allow it to build pressure all the way up to where it shuts off automatically. If it does and you hear no leaks, you're done! If you hear leaks, you make have forgot to tighten something down or you may have an unrelated leak in the offloading tube or at another connection. If not; success!!

1. Remove top shroud.
2. Remove broken motor bracket & replace new one.
3. Remove old regulator & install new regulator.
4. Trim top shroud because 2" diameter filter would not line up for installation.
5. Replaced top shroud & tested compressor.
6. Runs quite & hold air for days.
