Hello all

My engine came with a HICAS ps pump. I bought a used non-HICAS pump. The non-HICAS pulley has 3 ribs and the crank pulley has 4 ribs. Has anyone else noticed this?

I thought about using a 3 ribbed belt and just let one rib on the crank pulley go unused. Here is the problem: The only size belt that will work is a 345K3. I closest belt sizes available are 325K3 and 350K3 both of which are too big or too small.

What size belts do you guys use on your SR swaps for the ps pump?

 

Thanks Matt

I got that same info from srswap.com and it is wrong. The A/C belt does not use a 4PK880 it uses a 4PK890 which equates to a 350K4. The 4PK880 (345K4) is too short and will not fit around the idler pulley even when it is adjusted all the way loose.

I am starting to think I received the wrong power steering pump here. I will have to check the part numbers for the correct non-HICAS S13 red top pump.

Thanks again

 

Thanks for the info Charles. Thos belt sizes you listed are exactly what I found to work the best. I am having some issues with the power steering pump though. I have a few questions for you.

1. Are you using the KA or SR power steering pump?

2. Do you have HICAS?

3. If you used the KA pump did you also use the KA bracket?

Here is why I am asking all of this.

I am building an S13 red top. It came with a HICAS pump which has a 4 ribbed pulley. So does the crank pulley. I got rid of the HICAS pump in favor of a non-HICAS pump that I bought used.

The non-HICAS pump and bracket fit perfectly onto the block. The non-HICAS pump came with a 3 ribbed pulley which is held on by a nut. The HICAS pulley was not held on with a nut. It looked to be pressed on.

I have a set of GReddy pulleys. The GReddy ps pulley has 4 ribs and is held on with a nut. When I install the GReddy PS pulley it sits too far toward the pump and the belt is at a very bad angle.

Thanks
