On-board Air for 4.8 GRX
Posted: 18 Dec 2013 20:35
Well,
Read up allot on on-board air systems and watching multiple related YouTube video's.
After obtaining an second hand air conditioner pump, gathered for an on-board air system I intended to fit to a Willys CJ2A I had back in the day, I finally have a proper troll which would not be to bothered about the additional added wait. (Spesiaal paar prentjies vir Oom Mac) I also wanted to add a reservoir to add some volume (if required).
I obtained the following Helium Filter. What I liked about this tank is that it is stainless steal so rust might be a little less of an issue.
The filter material was removed and the tank re-welded together. After welding I had the tank pressure tested to 30 Barr just to be 100% sure and if possible I would like to push the system air pressure a little higher to increase the stored air volume. First trick was to determine the optimal place which would incur the minimal modifications and changes to the current set-up and configuration.
I decided to remove the current air conditioner pump bracket and tensioner and design a new bracket which would mount the current air conditioner pump higher up on the side of the engine opening enough space below this pump to allow me to fit the second pump to be used as the air compressor.
This design took more that 6 months as I am a mechanically minded electronic person. I first had to get to grips with the design package but managed to design the following replacement mounting bracket. The next picture indicate the test installation to optimize the pump alignment and ensure the new, longer replacement multi groove belt is tracking correctly. Next would be to complete the plumbing into the back of the Trol.
I will update this tread as it progress.
Hope to get this along quicker than it started off.
Cant wait to run the pump and check the air delivery of the system.
If all go well I would end this of with a short video indicating the installation and operation.
