Good Afternoon
I'm in need of a new Power Steering Pump Double Pulley. The OEM pulley is 6 1/2" diameter and all I can find is a Dorman 300-121 which is a 5 3/4" diameter.
The pulley is pressure fit. I used the proper puller to remove it and now after purchasing 2 different new pumps the old pulley just slips right on to the shaft with no friction at all. I bought the Dorman and the fit is tight and correct but the pulley is the wrong diameter.
Any help is appreciated.
Thanks

Ray,
I currently have two power steering pumps on the floor of my barn. One is 6-1/2 and that one is the older nut fastened the newer that needs the puller that locks into a grove seems to be about 6-3/8 but I was having a hard time and didn't feel like walking across the shop to get a real measuring device. Both are very rusty. You are welcome to both or either if I can get them loose. Just let me know.
