Q: If my servo valve is leaking can I buy a servo seal kit and fix it myself?
A: No, if your servo is leaking out the valve it has to be sent back to us to be fixed because it has to be drilled and centered on the dyno machine! If it is not centered it will turn one way or the other by itself.
Q: What would cause burnt power steering fluid in my steering unit?
A: It could be either a bad pump or line causing burnt power steering fluid! Also, check the pulley set up on your pump! If the pump is a 6" the crank should be 2 1/2 to 3".
Q: What if my rack and pinion steers easy one way and hard the other way?
A: This could mean that your pump does not have enough pressure, or you could have rubber debris in your servo valve, or possibly damage to your cylinder.
Q: How much pressure should I have for my pump to run the rack correctly?
A: You should have between 1000 to 1100 PSI.
Q: What should I do if my rack and pinion feels like it is darting?
A: Check the set screw on top of the rack housing to make sure it is not too loose. Also check the 9/16 nut on the end of the slave cylinder to make sure there is not too loose. If both of these are okay, it could be a loose drive pin, so send your rack back to be looked at because that has to be drilled and centered on the dyno machine.
Q: Which fitting goes on my pump and which one goes on my tank?
A: The "P" and "T" are marked on the servo housing, the "P" goes to the pump, and the "T" goes to the tank. If you can not see the "P" and "T" on the servo housing the 45 degree fitting next to the rack boot goes to the pump and the 45 degree fitting closest to the u-joint goes to the tank.
Q: What if my rack turns by itself?
A: You will have to send your rack back to be looked at because your valve holes could be twisted or you could also have debris in your servo valve. See picture above.
