never wash the compressor with acetone - if its intact, if you do want a good wash and clean then disassemble it to bits and repack it. If you want to flush it as is then change its oil 2 times.
btw with Harisson V5 you need to oil it up from the crankcase drain bolt, if you dont then the compressor will wear out very quickly. Its a unique design, if you take it apart you will notice that it will trap a lot of debris inside it in the event of a failure. Also be careful with the variable valve, if its flooded with oil the compressor will show its very weak, its not - its just the valve not allowing full stroke pumping.
changing the magnet coil is not too hard on a V5, its just hard to get it in Pakistan, and make sure you have a quenching diode in the power circuit to save the compressor relay.
