Outer Limits 4x4 Board

hey heard that you can change the spring that regulates the presure in early hilux power steering pumps giving it more pressure also a bigger pulley helps apparently does any one know where either item can be found

havent heard of this let me know if you find anything out. i put power steer into my 85, one of the best mods ive done but needs a bit of revving at slow speeds to help it out, would be good if i could eliminate this

yeah thats where the pulley would help but if you get one thats too big it might blow the pump. if i cant get one ill just make one but was trying to see if there was a cheets way

Could stretch the springs slightly as too much pressure will obviously make all the seals leak. Best bet would be fit it up if it feels underpressured get it flow tested and pressure tested as these are the 2 valves in your powersteer pump.

going to a larger pulley will cause the pump to turn slower. you need a smaller pulley to increase pump speed.

yeah larger on the motor as its easier to make

does any one know how many rpm a pump will handle as i dont wont to blow it up

as high as you can rev the engine? On my 4Y that get's to over 6.5K rpm.. not that I would even dream of holding it that high for any longer than a microsecond.

still a little lower then i wont mine to go to thinking of making mine do the equlivant of 7500 rpm and it will sit there a bit
