Hello I am in the process of restoring the air conditioning system. The system uses a Zexel DKV14G rotary vane compressor. The vanes were shot in the compressor as it was very noisy and would not develop suction and would not build pressure at idle or 1000 rpm, the pressures were equalized. There was quite a bit of metal and black residue in the inlet to the drier. Therefore being a former a/c tech and knowing it is almost impossible to flush the condenser, it is being replaced. Also the evaporator, txv, the dryer and of course the compressor will be new. I was mainly a ford& gm a/c tech, back in the late 90's early 2000's, I never came across a rotary vane unit.
A few questions:
1. For the 01 Isuzu rodeo, from what I have found online, some sites call for for 5.0 oz of pag 100 as a total charge and then some call for a compressor capacity of 5.0oz, so is the total oil capacity 5.0oz?
2. If it is 5.0oz total,would I put 2oz in compressor, 1oz. in dryer, 1 oz. in condenser & 1 oz. in evaporator?
3. I know to put the oil in the suction port of the compressor, but being a rotary vane, how would I go about distributing the oil to all the vanes?
4. Are there any special startup procedures for the rotary vane compressor, once it is fully charged?
Thanks for all your help!
