Air compressor problem

[Cheeky]

Loring,

Some PC's like the C5100 use the same part.

I checked my tool sites under my favorites and Sears looks to be just as competitive.

Loring, Sears buys the replacement parts from HF. The others buy it from the manufacturer

Apparently, judging from the failure pics, they bought the original from HF, too.

Picture of broken part attached. It's steel, not brass, and
the cross section where it broke is like .575 x .512" - ought to be pretty strong!
( I suppose all that steel to the left side is supposed to be a counterbalance to the bearing and piston, to keep the vibration down - doesn't work all that well ).

Thanks to all. I hope they have the part in stock. It's a **** of a mess now spread all over my working area.

You have eliminated the possibility that the reason it broke is that something further down the line is frozen, right?

Oh, yeah, I could turn the plastic fan attached to the eccentric and run the piston up and down, easily, since I did not have the motor to turn.

Got the part from sears today. installed with few problems ... the new self-tapping screw being too short and stripping out before it grabbed... I used the old screw. I used a torque wrench because the parts list clearly stated it needed 100-120 in-lbs, which I converted to 8-10 ft lbs.
Heck, it took 10 ft-lbs just to turn the self-tapping screw. (probably why the first one broke - they over-torqued it at the factory)

BTW the new part is beefier than the old - they made the cross section thicker and therefore stronger... improvement on a bad design, I guess.

P.S. I guess i should say it all works, now.

air compressor.......

Loring I think that part is a machined counterweight for the piston/ connecting rod that helps to maintain balance on the assembly while the piston moves up and down in its travel. If this were a 60 deg. v-twin arrangement it probably would not have this part, because the opposing connecting rod would also act as a counterweight to the opposite cylinder.
My thoughts...probably no help here, buy thought I'd chime in anyway
with two two cylinders, hope you can get it fixed all the same...eezlock

Somehow I dredged up this old post while searching. Amusing reading. I should say the compressor is still working 13 years on after the repair...
