"Start Valve" = pressure indicator?
by: Doug in s.d.ca

Do a search for sp1804s on this site (there's one on the home page about screen full down).

Does your valve look like that?

If so, you can likely just put a plug in there. It's got a real unloader, like mine, so it really just tells you there's pressure on the head if it's up.

Alternatively, mine is fixable, maybe yours is too.

Start Valve for Model 67847

Since I do not have the manual, I cannot check, yet if what you refer to as the Start Valve for Model 67847 is what I would call the pressure switch, there is no shortage of suppliers.

Simply Google pressure switch for Central Pneumatic 67847 as I just did and you will find a number of sources.

If it is not the pressure switch you are referring to, please comment.

67847 crankcase gasket leaking

Well I have a model 67847 and water got in the oil plug so I removed the crankcase and gasket but now I can't seat it right so when I turn the compressor on it leaks like crazy and now the compressor does not come back on unless I drain the tank and hit the reset button

It seems you might be a bit frustrated with your Harbor Freight / Central Pneumatic air compressor, hmmm Scott?

You might like to let us know how water got into your oil fill plug? That might be a good story. If you wish, add it as a comment here.

If the gasket doesn't fit or hasn't been replaced properly, then you know, you've got to take it off and install it again. Sorry, but that's just the way it is.

As to having to drain the tank to get the compressor to start, have a look at the unloader valve page and ensure that yours is working.

Or, if your compressor got really soaked, check that the start capacitor is working. See that page on this site as well.

Cheers and good luck,

Bill

Central Crankcase Gasket
by: Bo Deadley

The gasket seems undersized for the faceplate. I tried several times to install & reinstall without luck. I finally cleaned residual oil from the faceplate where the gasket inserts, and cleaned the gasket insert edge, then sprayed a shot of NCF Hot superglue catalyst, put a drop of Gap Filling Hot Stuff superglue on the gasket edge, & tacked it in place. I did that once on each edge. After a couple more attempts, I finally got it seated by starting at the bottom edge by the sight glass & moving up.
What a pain & what a mess, but I was able to escape with my virtue intact & they are using the thangy right now.
Good luck comerades!

water in compressor
by: scott anderson

Well firstly I keep it outside because I don't have any kind of storage I know but that's how it is.

Secondly the gasket from the crankcase cover where the sight glass is I took it off to clean all the water and oil out but when I put it back on it leaks like crazy. Its a flat gasket that covers the whole cover but when u put it on it moves so I'm still working on getting it to stay in position.

Thirdly what are those parts you are referring to for the starting.thanks for the info

Can not find the capacitor for 67847

i have looked up the numbers on the capacitor and there are no capacitors that we can find on the internet with those numbers so we can not replace it.

I have the Central Pneumatic model: 67847

What it is doing is shutting off and won't run no longer than 30 seconds. then you have to reset it, and after you rest it, it will do the same thing. No matter how much air is in the tank.

Capacitor for 67847
by: Bill

Read the troubleshooting pages for information on things to check when an air compressor acts like yours is.

Also, read the pages on capacitors to find out how you can replace the existing one with a non-OEM version.

It's all on this site for your use. Please help yourself.
