If one of those repaired rods breaks, then you can find out how expensive the other compressor parts are - it could take out a piston, the crank case or...

Craigslist, ebay, northern tool, harbor freight are full of cheap compressors.

I think Snag is a ****ing moron. I felt that way long before he started this thread.

If it tipped over and the pulley didn't bend BUT it broke the rods I
would say it was junk to begin with. Just how much play is in that
crankshaft to allow it to shift far enough to break the rods?

TIG will just cause problems in the HAZ. Just holding them in alignment
and welding won't be much good since the rods will then build up
stresses in other areas, those will be enough to cause flex or breakage
as well.

If this is a good brand you can probably buy all the parts easy enough.

All this talk of repairing con-rods is silly. Make new ones, if you
must.

BUT! My real question is this: What sort of situation would have
someone tipping over and allowing to fall a compressor WHILE IT WAS
FRIGGIN' RUNNING?

There is no way that could have damaged the con-rods if it were off.
So...
What the HELL did you do? (And maybe WHY would be a good one, too.)

Actually , I was backing a load of lumber in and the end of a 2x4 12 feet
long pushed it over . I was watching the other side to be sure I didn't back
into one of the legs of the carport that's now my shop space . Compressor
wasn't running , wasn't even hooked up . It landed on the pulley , pushed
the crank bearings out and snapped both rods . eBay has 'em for 22 bucks
each , and I shoulda repaired it then ...
The point has been rendered moot . I tore the new unit down , discovered
that the top 2 rings on both pistons appear to have been installed upside
down . Bottom edge of both was shiny , top edge has never touched the
cylinder wall . No wonder there was blowby ! So I did a light hone on both
cylinders and turned the rings over , seems to have solved the problem . But
next trip to Memphis I'm bringing the other pump up for parts to repair the
one with busted rods .

Greetings Snag,
I've been reading this thread and if it was me I would weld the damn
things. Only because it would be good practice. If the compressor
ended upworking then that's great. If the rods break catastrophically
then you just get some entertainment. And a great story to tell
friends when you are shooting the breeze. I would not depend on the
machine though. Make sure you have another compressor online and ready
to go. And some advice for your other pump. The last pump I bought
came with instructions to run unloaded for an hour before regular use.
Just let it pump to the atmosphere. Failure to do so would cause lots
of blow by. The pump was from Grainger.

I tried ... one came out very nice , the other was a miserable failure .
New rods will be here later this week . Learned a lot about welding
oil-soaked aluminum ...
That new pump came in a very beat up box , no instructions at all . It had
been turned upside down at some point and all the oil was gone . Had some
other problems too but they were minor . I ended up getting a 25% refund ...

He'd better be looking waaaay up when he does that.


As for Snag's story, **** happens and anyone who does a lot of work,

The chance that it will work without issue is virtually non-existent.
The chance that you'll get proper alignment when you assemble the broken
pieces is not good, and the notion that they will remain where you put them
when they are welded borders on the absurd. All you'll need is a loss of
parallelism between the wrist pin and crank journals and it won't perform
well, if at all.

Consider this. If the rods snapped when the compressor tipped over--they
most certainly must be made of gray iron, which does not enjoy being welded.

My money says you should pursue other options. However, if you do continue
the course, I'd enjoy hearing how it turns out.
