Drinks.
This tire change is getting expensive. I believe the last time I was at it
I ended up pinching a tube, so I tried another which actually had a small
puncture as well. Since then I picked up two more tubes and today I got a
chance to give it another go, while the bike sits in the garage with all the
fluids draining.
I dragged the tire changer out, while once again cursing the limited space,
and pulled the top side of the tire off the rim so I can pull the punctured
tube out. Then I turned on the compressor and replaced the tube with a new
one and, as per some a tip from Jinks, put some air in the tube to help give
it a little form to keep it out of the way of the tire irons. Then I
started putting the tire back on, noticed that the compressor was still
running and usually it wouldn't take this long to fill it, so I shut it off
and got back to the tire.
Apparently I STILL wasn't careful enough and I ended up tearing yet another
tube. As I said, this whole do it yourself tire change thing is getting
expensive. So out came that tube and in with the "spare" I bought. This
time I gave it a bit more air and was much more careful while utilizing the
tire irons. Once the tube and tire were back in place I started to fill the
tire with air, that's when I noticed something odd, the tire wasn't filling
real fast, I could get it to about 30psi but not more. I went over to the
compressor and there was only 30psi in the tank, so I turned it back on, and
for all the noise it made, the psi reading didn't go up. Hmmm, not a good
thing.
I can fill the tire up at the gas station, so I'm not worried about the tire
at the moment, so I decided to pull the cover off the compressor to see that
might be up. I let the remaining air out and unplugged it (electric
compressor) and removed the 2 screws holding the cover on and saw this:

The only reason for that shot was because I've never been into the
compressor before and wesn't sure what I'd be looking at. Once I had the
cover off I plugged it back in and turned it on to see if I could see
anything obvious. Everything seemed to be working, but while looking around
I could feel air shooting at me. A closer inspection showed that the copper
pipe leading into the compressor was broken, so no air was getting into the
tank.
It's a little hard to tell, but from here you can see that the pipe going
into the tank isn't lining up with what I assume to be a compression
fitting.

I'll take the compression fittings off and see if I can find a replacement
for the copper hose, not sure where I'll start looking around here, but I
may check around the shop at work to see if it's something that someone
there can make up. Of course I'm no metalurgist, so it might be brass.
Anyone know what's normally used for high pressure fittings?

That's a piece of standard copper tubing . Get it at the hardware
store , along with two new compression sleeves . Bend to shape/cut to
length , slide the nut then sleeve on ends , insert into fittings ,
tighten snugly and then a bit more . This is a common replacement item ,
especially if the compressor is used a lot . Vibration causes metal
fatigue (actually work-hardening) , then it cracks and you replace it .
Doesn't help that the air is quite hot as it comes out of the pump .

Snag , done more than one at the cabinet shop ...

Thanks for the info. The good news is the tube isn't broken, but I'll get a
couple new fittings.

False alarm, I pulled the hose off to discover that it wasn't broken, it
just came out of the fitting. I put it back in place and tightened it all
down and it's working once again. I buttoned it all back up but it backed
out once so I won't be surprised if it happens again. I should pick up a
new compression fitting to have on hand for the event.
I'll put the new tire on tomorrow, now that spring is here. <g>

I have had mine break a couple of times because it is exposed and in and out
of the truck often. First time was able to shorten the tubing to make it
work the next time had to replace the tubing.
(smaller tube also)
