Re: 1997 Sebring 2.5L A/C warm (details inside)

One potential root cause is that the single discharge valve of the scroll compressor is not fully closing which allows warm high discharge gas in the rear discharge chamber to re enter the scroll area. This is referred to as wire drawing and could be foreign material under the valve seat, cracked di...

Re: Printed a Shaft Seal Installer Tool on my 3D printer

Maybe we could have fun w/ your 3D printer w/ a grill escutcheon for Tim (ACKITS.COM) and 3D hood ornaments for bohica2xo's compact PU ('Yote) and my F150 (Boar head w/ tusks).

Re: New Sanden squalling above 3000 rpm

Hi Mr. dogbone,
Since the A/C is unacceptable, I'll take it off your hands.

Re: GPD R4 scroll

The Trailblazer cooling with a TRSA105 scroll was great over 30 mph and barely acceptable at idle.
The TRSA90 is aprox 15 % less displacement, so the drive ratio is the final solution.

Re: New Sanden squalling above 3000 rpm

Smitties and underhood/firewall insulation might keep the rumble masked

Re: bosch/Behr Wing Cell (vane) compressor R134A

The Bosch vane rotary was sold by BEHR and is not a suitable for R-134a retrofit due to elastomer incompatability long range.
Th "gauze" is a absorber for refrigerant oil which seeps past the shaft seal and could initiate clutch slip if not stopped.

Re: New Sanden squalling above 3000 rpm

All/100% of SD508s are noisy at 2800 compressor rpm. Comp itself is ok. The addition of a aftermarket suction muffler reduces noise 20% and a discharge muffler reduces NVH another 15%. Oil quantity is ZERO influence. Get use to it or swap for a SD7H15 or a swashplate drop in or a SD708 (bracket mods...

Re: Need to find the right part to replace my a/c clutch

Looks a lot like the OEM Sanden SD7H15 with around 100k mi If the clutch friction surfaces wear and the disengaged air gap gets too large, then the flat springs are flexed beyond their safety limit, the springs fatigue and crack. This web site often recommends removing adjustment shims to compensate...

Re: Knock off compressor

Brad, 10-4 on the 4 cylinder boat anchor Clutch friction surface finish is optimal between smooth and rough. Too smooth is also undesirable. I prefer Iscar cutting mills and lathe, carbide insert, tools from Israel. Gear cutting hobbs (for the anti-rotation gear on a wobble plate compressor) can hav...
