Hey all, I am looking at replacing the bearing in my ac compressor pulley on my 3vze. The pulley spins ok but is a bit grindy sounding when i spin it by hand... and noisy as hell when the engine is running.

But when taking the pulley off i noticed the compressor is pretty hard to turn by hand. I can still manage to turn it, but not more than an 1/8 turn at a time. Ill look to get a proper torque value if i can fit my wrench up there (it is still in the truck.) It is likely the original compressor from 1989. I am afraid to ever disconnect it because it does still work and i still am running r12.

I just wanna know if compressors are usually pretty hard to turn?

Thanks

Ps still currently fighting to get the pulley off, i am going to try and make the sst 40mm m8 bolt with the end ground down. Unless i can rent one.

 

Update: I got the pressure plate and pulley off, and got my torque wrench on it. It doesn't click it at the lowest reading of 5 ftlb. So i suppose its under that. Still just wanna know if this seems normal.
Thanks

 

If your ac holds refrigerant and gets cold, it's working as it should. There is absolutely nothing you could do to change any perceived tightness in the compressor, short of changing it out.

This you will have to do sooner. or later, when it stops functioning.

Replace your clutch and idle bearing and go.

Even though I have proper AC tools and clutch pullers, these repairs have seldom held up for me, and so I just change the compressor out for a new one. NOT a 'rebuilt' one.
