Fill time to topoff sucba tank
Topped off my scuba tank from 2200psi to 3100psi and it took a little over 6 hours. I shut it off avter 3 houra AND LET IT COOL OFF AND LUBED SHAFTS AND THEN RESUMED. 6 hours was total run time.
No problems and it works like a champ, serial #40
Crank Shaft to Connecting Rod Bushing
As I was inspecting my compressor I noticed that the bushing #45, located between the crank shaft #19, and the connecting rod #53 has completely worn down on one side. Causing play in the connecting rod and a clunking noise when running.
With the crank arm pointing to the two o'clock position, there is an 1/8" of play in the connecting arm. I can move the shaft block and pistons in and out an 1/8".
I want to disassemble and post some pics, but I want to find some crimp washers first. I have never had any luck when removing them.
Any advice would be appreciated.

EDIT:
Well the washers came off real easy.
Now that the connecting arm is off, when is slide the pistons in and out, there is a spot as I begin to insert the pistons into the cylinders where is hangs up slightly. This is exactly where the connecting arm failure occurred. That bit of resistance was enough to wear out the bushing on that side.

EDIT_2:
I removed the stage 2 cylinder and everything checked out OK. The resistance I am feeling is actually the piston passing through the o-rings. So there is not a whole lot that can be done about it. The delrin sleeve slides smooth and easy. I re-assembled and purchased a new bushing from Lowe's. Not exactly the same but just like #46. So I just knocked out the old one inserted the new and cut off the excess with a hack saw and cleaned it up. Back up and running now.
