Step 18
Remove the brass plugs
- Use a 3/8 inch open-ended wrench to remove the three square head brass plugs on the bottom of the pressure switch.
- To remove the plug that opposite the air tank nipple, brace the pressure switch assembly with a pair of channellock pliers or something similar.
- You may need a lot of leverage to break the plug free.
- During reassembly, transfer these plugs to the new pressure switch if it does not include new ones.
- During reassembly, apply green thread locker (Loctite 290) to the plug threads to prevent the plugs from loosening.
