Re: A/con idle up or idle cutout switch

The 61 Catalina that I was air conditioning had a 7.25" C/s pulley on a noninterference engine, so I was using it as an example of how to calculate the inputs so that the max comp rpm rating is not exceeded. My 2 cents for specifically for T bird: Since you are fabbing pulleys (as I have given ...

Re: A/con idle up or idle cutout switch

The Sanden cut out was only for wide open throttle clutch cut out for acceleration enhancement. I rigged a WOT switch on my 59 Impala (when I was a kid w/ MARK IV building ACs for my cars out of trash cans) using a microswitch and distributor advance pneumatic diaphragm solenoid on a mounting plate ...

Re: Car ac not cooling when weather is hot.

FYI: Civic engine rotates CCW. SDS508 Sanden spec is CW rotation because of gear engagement timing verses piston TDC. Timing has a large effect on compressor noise and may decrease compressor life 10% to 25% but pumping capacity is OK. Chinese knockoff rotation unknown. Sanden Singapore makes one mo...

Re: Tube & Fin Condenser on Roof?

T bird,
Outback sunshine may have heat stroked Davo, thus "HF" misprint.
KF is a compressor cylinder head made in Japan and used in the USA with "KF'' cast in 1/2" letters below the oversize 1 1/16 (#12) threaded suction port.
If you need one, try Tim for the part #.

Re: Tube & Fin Condenser on Roof?

Davo, Today a diesel 2.5L Defender 110 sold at Barrett Jackson auction for $60,000. If you need more compressor capacity, there is a little known SD7H15 development called "enhanced". It was developed to replace 210cc compressors on giant Komatsu and CAT mining trucks and validated at the ...
