2008 Toyota Yaris 1.3vvti fitted with Denso 5SER09C compressor!!!!

Postby SYN616 » Wed Aug 29, 2018 3:34 pm

Hi all

I have searched far and wide for the answer to this question and stumbled across this forum. Im at a loss to find out the torque specs for the retaining nut and tolerences for the clutch plate for my compressor!!!
I've managed to find a replacment pulley and clutch plate but can't find any other information regarding this compressor anywhere!!!

For reference the compressor info plate reads as follows;

DENSO
5SER09C GE447260 - 2331
HFC134a ND-OIL 8 11 J 13287

If anyone can provide any info, I would be eternally grateful

Thanks

I can't find any specs for that compressor, either. But as for the air gap, .020" is the standard that I see most mobile A/C techs going by and is the one I use. Any wider than that and the clutch might not engage, especially an older unit having a somewhat weakened coil. You can go tighter as long as the engagement surfaces don't drag with the clutch disengaged.

Lacking any torque specs, I would tighten the retaining nut by feel. It probably has an M8x1.0 thread, which won't need or tolerate a whole lot of tightening. Using a torque wrench, I'd guess that 144 inch-pounds (12 foot-pounds) should be about the maximum. You could put a drop of blue thread-locker on the male threads for a little extra insurance.
