Isuzu AC, Pipes, diesel pumps & backhoe repairs

Hi again and welcome to the channel. Today is another 'mixed bag' of goodies. Firstly, we swap out the noisy AC compressor on my Isuzu truck, add oil and re-gas the system, and also do a small modification to the wiring to eliminate 'clutch drag' on the compressor.
Then myself and Wayne from work, go out and pick up a bunch of concrete pipes for an upcoming repair on a creek crossing on the property that I wok on.
Next is getting a couple of old diesel powered water pumps checked over and seeing if we can get them up and running again.
Finally, we have a quick look at the 2nd hand hydraulic pump that I purchased and asses it condition and 'usability'.
