Next is the air conditioning and power steering. The original idea was to have a seperate motor direct drive on each pump. (As seen by previous posts with the testing of the starter motor).

This Hilux steers quite easy without it, but the rule says it must stay and some vehicles do require it, so we make it work, and learn the drama's. I believe it is possible to swap steering boxes with the same type of vehicle that does not have power steering.

The motor is a 12v series wound Advanced DC. With the change of mind in application, a short shaft needed to be fitted for a set of pulley's. This changes the direction of spin, compared to direct drive, but thanks to ADC in the States they sent me the wrong one. It spins the right way. The brackets will be painted in due time.

The standard size pulleys were used and the current draw was quite high. So a larger pulley was adapted to the power steering. It made no difference to the current draw so we assumed that was just the power consumption to run the motor, but it did allow the motor to spin faster. So we set out to cast and machine 2 new pulley's. With the 2 larger pulley's the amp draw is now 150 amps, both pumps running. The air-conditioning still cycles on and off, as normal.
