aircon compressor for tyres etc

Run it from the PTO on the Rover.

The starter motor has been tried, it is not very good, starters draw about 200 amps and get hot after about 30 seconds. You can fit the unit under the bonnet on a bracket off your air con. its a close fit but it can be done. Eric.

If you only want it for tires etc, just get a Blue Tounge, or Big Red.. Plumb them into an air tank from a truck wrecker..

Alex,

I've been looking at this myself and despite the advice to the contrary it can be done. The starter motor is heavy and not designed for the type of load you are applying. I'm looking into a brushless DC motor to keep the weight down. The one I have seen commercially available uses a series wound winch motor. It is heavy but does a brilliant job. I am currently in the US and am heading back to Oz in January, where I will look into it more closely. If you want to start the seach you need a motor of around 4-5hp and around 2000 rpm. Look up the motor manufacturers and they should have something available. then it is a matter of a direct connection and you are off like a frog in a sock. Let me know haw your search goes.

cheers
