Re: No low pressure

I would remove 6 bolts on the rear of the compressor and the rear head and inspect for a loosened bolt for the retainer of the discharge valves.

Re: Oil amount determination with different style replacement compressor?

If it was genuine Sanden the correct oil amount in already included inside the new Sanden replacement compressor which has generally been 8 oz for a CCOT system.

Re: New compressor. Not cooling well.

Failed compressor valves allow rapid high to low side equalization reverse gas flow carrying contamination through the compressor itself into the suction line, rather than through the normal forward expansion device flow. Compressor exchange without suction side flushing can result in multiple compr...

Re: Stuck Compressor Clutch Plate: Suggestions on Removal

FYI: The overheated field coil shows the imprint on the back side that it overheated the front compressor nose housing which can result in a crispy critter shaft seal that could leak on (1) the outer diameter or (2) under vacuum through the Teflon front lip or (3) the rear elastomer lip seal under p...

Re: Stuck Compressor Clutch Plate: Suggestions on Removal

Rotor pulley may need replacement because it appears to have a crispy friction liner with missing surface.

Re: AC accumulator draining too fast, high hi side

Think you have a TRSA105 scroll compressor which normally causes gage indicator bouncing on the high pressure gage due to one discharge pulsation per revolution. Pressure data could be normal if ambient temps align. TPS (compressor thermal protection switch) seems ok becuse neuisance cycling seems t...

Re: 1999 Mack MR688S inefficiency

Your problem is typical of older trucks that have had several compressors changed without flushing old oil out of the system. oil insulates the internal surfaces of both heat exchangers and reduces heat transfer. Typically truck systems have 8 + ounces of oil and replacement compressors come with a ...

Re: Stuck Compressor Clutch Plate: Suggestions on Removal

If you get the magnetic field coil out it likely has a one time thermal fuse buried in the winding and is not practical to repair. Failure root cause could be heat due to slippage from excessive air gap. Replacement coils, if avaliable cost almost as much as Tim's great better than new new knock off...

Re: Stuck Compressor Clutch Plate: Suggestions on Removal

Just a guess,
Orange center looks like sintered bronze washer not a splined shaft. If so,strike the washer from the side and it may pop out, exposing the shaft. Reinsert the center bolt and lightly hit it.

Re: John E. Mitchell Allegro Mark IV Parts Source

Blower switch nut was overtightened and cracked Plexiglas. J & N auto air conditioning in Harlington TX has old Mark IV stuff. Hope this helps. After making all the drawings on the Allegro, I put one in my 56 Chevy PU and could hang meat in it. Problem the the back window frosted on the outside ...
