Craftsman air compressor model 919.16726 will not come on

SOURCE: air compressor won't run

Don't run it with the head off! the cylinder will just up and down with the piston and ruin the seals again. I have three Craftsman compressors in my shop and I've torn them all down at least twice. Rather than pay for the kit, I went to NAPA and got a roll of cork gasket material and made my own seals. They don't last as long but they work great.

I'd be willing to bet your seal it just too tight. I made this mistake the first time around too. it's not a very good design as the piston tilts through the stroke. I would try putting a light coat of heavy weight oil on the cylinder wall and move the piston by hand to lube the seal.

SOURCE: Oil capacity for craftsman air compressor circa 1978 model #106..

I have a 2hp craftsman air compessor with a two cylinder pump, Here is the info from my manual as far as oil capacitity:

Remove oil fill plug and slowly add
a compressor oil until it is even with the
top of the oil fill hole. NOTE: Do not
allow oil to be lower than 3/8"
from the top at any time. When filling
the crankcase, the oil flows very slowly
into the pump. If the oil is added too
quickly, it will overflow and appear to
be full. NOTE: Crankcase oil capacity is
approximately 16 fluid ounces.

I buy my compessor oil from Lowes in the tool department. It comes in 16oz and sells for about $3. I wouldnt worry about how many ounces it holds but rather that the oil level is to top of filler hole. Lowes also sells a synthetic oil for about $7 and is recommended for severe conditions (hot / cold / used all day). Good Luck!

SOURCE: no air pressure

TRY ADJISTING THE TANK PRESSURE KNOB WHILE RUNNING ,TURN TO THE RIGHT 1/4 TURN UNTILL YOU SEE NEEDLE MOVE .MOST TIMES FACTORY SETS AT 0,SO YOU NEED TO ADJUST IT .MY ADVICE IS NO MORE THAN 90-100 PSI TILL YOU KNOW WHAT YOUR RUNNING MORE OFTEN
