I have a 1985 FJ60. It had the original PS pump but it was leaking really bad. I did some research and replaced it with a Saginaw pump. I used a bunch of washers and bolts to shim it out and get it mounted straight. I had to use my old pulley and bore it out to the correct shaft size (not ideal) End product is that it works but I'm having issues at lower RPM. so when I'm coasting through a parking lot or parking I basically have no PS but when I give it some RPMs I have no issues. I'm guessing the pump is either powered differently than the original or the pulley size needs to be changed to get more RPM at idle. I'm looking for a better PS solution. Sometime with a bolt on kit. Plug and Play or a pump part number with a pulley part number. Anyone have any suggestions or ideas. I currently have 31" tires but will be going to 33" tires soon.
