Does anyone know how to pop the workings out of a Harrison R4 compressor? I have the clutch and clutch magnate off. From what I see in the drawings, I should be able to lift tab on back and just push all the guts out the back??????????????
The shell is a press fit over the cylinder- the shell comes off -towards the front of compressor- once you bend the tab back- good luck getting the pistons out- they are threaded in now- and take a special tool to unscrew them.
The number one A/C diagnostic tool there is- is to know how much refrigerant is in the system- this can only be done by recovering and weighing the refrigerant!!
Just a thought.... 65% of A/C failures in my 3200 car diagnostic database (GM vehicles) are due to loss of refrigerant due to a leak......
