I also worked on my compressor. Replacing the pressure switch and safety valve and increasing cut-off maximum pressure from 100 to 125. What I have to do now is watch the pressure and unplug as the pressure switch would allow it to keep running.

The old parts out and the new going in.

Inside the pressure switch you have a set of contacts when the pressure pushes the diaphragm it will separate the contacts at the appropriate pressure dialed in.

Completed and back together except for the plastic cover to hide the parts replaced.

My failed attempt or not much of one at cleaning. I did get the platform mounting plate inside pretty good.

Fixing everything so I could sell this one and purchase a larger one my Dad has.
Now to test it out!!!! I don't need to test it, the work is excellent!! :-P :-P I better anyway. It pumped up well and cut off at 125 PSI just like it should, alright.....but I hear a leak. :-o :-?
Come to find out I did not pay attention to what type of metal I was screwing these fittings into and I went too far. Split the sides of the threads on the safety valve and the gauge, I think the safety valve is the only leaker.

After pondering what to do now with a perfectly good was and still is working compressor sans the leak. I am going to try the HTS 2000 rods you may have seen at the International MC show. The one they use on a aluminum coke can and on a aluminum motorcycle case for a ear/tap that a screw goes through broke.
Looks good at the show, here is the video.

If his doesn't work I will probably put a single tree with one gauge on top for tank pressure. I hate to destroy a tool when most all functions are working. I am chasing myself financially now but hopefully I can keep it from going to the scarp yard.
The rods work on a coke can as shown but I can't get the metal hot enough on the compressor. My acetylene torch is out of oxy. I tried propane and MAPP gas albeit the cylinders are not real full for a hard flame.
oh!! that's easy, Go to the corner store and pick up one of those "wind resistant" lighters, you know the ones that have more of a pressurized flame than a regular bic? that will probably do it!
Maybe I need to use some starter fluid and blow it up! (http://i203.photobucket.com/albums/aa214/TLRam1/Smilies/a-blowupfire.gif)
The cast parts you are working on are more likely pewter or (pot metal) Which resembles Aluminum but will not braze or weld. Another possible repair would be to use a close thread nipple, coat the threads with a product call Devcon two part metal epoxy (a little better than JB weld in my opinion) screw the nipple in as far as you can without spreading the crack any farther, then finish coating the outside of the housing where it's cracked (liberally). Be sure to let it completely cure before using. Your pop off valve can be attached to the nipple before you screw the nipple into the cracked housing, just to avoid unnesscary pressure on your repair until it has completely cured. This is a tested repair, Cast pewter cracks very easy.. :-(..
I think you are on to something Charles. I thought it was pot metal also and according to this site this stuff would work with pot metal. If I were going to keep this I would try and still might for the sake to see if it works.
In order for the next owner to be problem free I will replace the regulator also this is probably the least expensive and ensure of it being fixed. The other issue is the time I am spending on the repair. I wish I had more time as these are the sort of issues I like testing various products on.
performs well on aluminum, cast aluminum, pot metal, copper, magnesium, and all white or porous metals.
Boy, that HTS2000 is some impressive stuff. I need to find a project to test some of it.

Unfortunately, no.
Wanna go in halfsies and buy some? Looks like a good investment. I have an acetylene torch. :smile:
Where were you when I wanted to split some of this.
Dave I found mine on ebay for about 15.00. You don't get much but enough for me to try on the cheap!
I would not mind having more, if we could split with more people I would have an interest.
Search for------- HTS 2000
Started back on this last night, decided to find replacement parts and re-plumb. I did a mock-up to ensure all would fit where I needed it too and prevent redos. Initially was just going to put a stem with a safety valve and hose connector, instead I put it together with a regulator as it was.
Here is the start of final assembly (hopefully).
Beginning the assembly process of the new plumbing.
(http://i203.photobucket.com/albums/aa214/TLRam1/Motorcycles/Wrench%20Session/DSCN8392.jpg)
Install of the new safety valve and tank pressure gauge.
(http://i203.photobucket.com/albums/aa214/TLRam1/Motorcycles/Wrench%20Session/DSCN8394.jpg)
Attached new regulator and plumbed for the outlet hose.
(http://i203.photobucket.com/albums/aa214/TLRam1/Motorcycles/Wrench%20Session/DSCN8395.jpg)
Installed copper pipe from compressor to tank.
(http://i203.photobucket.com/albums/aa214/TLRam1/Motorcycles/Wrench%20Session/DSCN8396.jpg)
Finished after attaching new pressure switch, hose and wiring to the motor.

Looks so good I had to take a photo of it! Came out great, but test it now, no need this is great stuff here!! Plug it in and ...........nothing, unplugged and replugged, how can this be. I did nothing to keep this from running. Meter time, no juice to the motor or pressure gauge. Plug looks like it's tired, off to buy a plug and replace. NOW we are really ready THIS time!!
Plugged it in, hmmm, nothing. Darn thing I am ready to blow it up! Meter time again, juice to the pressure switch and motor, gosh darn it, what did I do to the motor. I did not wire the motor up correctly.
Now we are really really really ready!!! Plugged it in....I feel like Hootmon now, crack the champagne, it runs and well at that with no leaks!! I put the quick disconnect on the end which stays cocked for an attachment, no pulling down the sleeve to add your attachment just push it in than the sleeve slides up to lock it. You do have to pull the sleeve down to remove your attachment but stays cocked until you add another device.
Completed with new plug!

On another note.
In the middle of all this my garage door and a few lights stopped working, smell of wires burning. May a long story short, previous house owner did a makeshift splice in the wiring up in the attic. My son traced and located the splice as he moved the wires it started burning. Wow, we were lucky it was caught before a house fire.
Three wires tied together, a bunch of tap around the area, this tape was too melted to take off.

It would be difficult at best to prove that the PO actually did this atrocious hack job on the wiring. This is so out of code that there should be some punishment to anyone who does such dumb stuff.
Glad your house is still standing.
I have an air compressor that looks a lot like yours. Bought it at auction in 1967 for $110. On the way home, it fell over in my pickup because I didn't secure it properly. Bent the fan/pulley that attaches to the compressor shaft. I decided to just run it until it failed. After 40 years, the belt is still good, and the beast still runs and pumps air. It was a Sears, but the tank and compressor are the same, I am sure, as yours. I have changed the oil a few times, and cleaned the intake filter numerous times, and put a petcock to drain the water out of the bottom regularly. Other than that, I haven't touched it.
Installed shop air two years ago when the wife found a bargain on a 5 hp 60 gal unit, so it isn't used much these days, except when I need to take it somewhere away from the shop/carport. I can't tell you how many rooms, walls, etc. that were painted, or how many tires inflated, stuff blown out, etc. with this compressor. Hope yours lasts as long. 8)
Wow, with work like that and the right "plumber's crack" you are ready to start roughing in houses. :lol:
Glad it all came out well.

Yep and I wish I was the deliverer.
The compressor, I am actually fixing up to sell and yes, it is a great compressor. Not to offend anyone who has one, or a different opinion, but the reason I repaired this is because of the type of compressor this is. If it was one of the noisy, inexpensive to make oil-less ones I might have dumped it.
These types (twin cylinder) also put out more SCFM than the oil-less ones and will be replacing this one with another older model just larger but having second thoughts as this fits nicely in my garage and does what I want it to and good ones are hard to find. New ones like this are expensive.
