Phil.
The pto speed is to low to run small compressors. Eric,

If air compressor (old air conditioner pump) is connected to a 1:1 PTO and the engine is on the hand trottle at say 1000 - 1500 rpm in 5th gear surely this would work ???.

Hi again Phil
If you have a diesel, i have seen Magnum air compressers running off the air belt and they sit where the power steer reservoir is now (it is repositioned further towards the passenger side) A longer air belt is then required.
Then there is the way i modified the 1fz.. i took the air cond pulley off and machined a datto waterpump pulley to slide on behind, making a double pulley. It is secured with 4 spot welds and a shrink fit. This is harder to do, but a better setup, having a individual belt.If you have room around that side of the motor, then your in luck. Go to the wreckers and look for a sigma or L300, or similar vintage mitsubishi with a Sanden air compresser. These are the ones that Endless Air use as a base compresser with a grease nipple in a side plug instead of oil in the gas.

I used to run a magnum on the 1HZ donk before I put the chevy in. Spot welded a second pulley to the aircon belt tension pulley & as mentioned repositioned the pwr steering reservoir further back on the air intake manifold. You only need a short vee belt to drive it. The top radiator hose setup will need modifying with an "S-Bend" hose to give clearance for the compressor pulley. Cheers.Have Wheels Will Travel

Phil.
The pto gear is run agianst the intermediate gear in the transfer case, this in the early models at least, was about 1/3 engine speed, the design speed for the
winches was 500rpm. to check it out count the teeth on the 4 gears and calculate the ratio. Eric.

Hi Eric
Had transfer case apart today to change a very noisy output shaft
bearing, while in there checked PTO gear setup, PTO gear is driven by
the gear box output shaft, the Toyota manual also shows this, this gear
dosn't run against any other gear in the transfer case. The PTO gear is a straight cut gear of 30 teeth and is splined directly on the gear box output shaft (transfer input). so this means to me that if the gear box is
in 4th gear and the engine is running at 1000 rpm the PTO gear must
also be rotating at 1000 rpm. I havn't got a PTO box to bolt to the
transfer but I'm guessing that any reduction is done within this box.
Phil.
