Cummins 5.9 PS Upgrade to ZF style
Worked well for me to upgrade my 2005 Dodge 2500 Power Steering to the improved ZF style pump. ZF pump requires this pulley. I purchased a bolt and 3-5 washers at local hardware store to press it onto the pump, worked well. Needed to leave a bit of gap at front (pulley out a bit, not flush. 1/8, I believe.) for it to align properly to the belt. Leave 1/4" gap, install on vehicle, then use a straight edge to do fine tuning of belt alignment on pulley press.

completly wrong size-shaft diameter wrong by a gross amount
I bought this Dorman 300-149 to fix the 2003 dodge 3500 cummins 5.9 it was purchased for. Through various events it took longer than expected to actually replace the pulley. Tonight I took off old pulley and put new one on. EXCEPT it did not fit. AT ALL!!! The old pulley measured ~0.61/0.62 center hole. The new pulley measured ~0.65 center hole. These pullys are designed to be a press fit. The new pulley slid on by hand and wobbled around substantially. Too bad I am out of my return window-I may try to dispute this with my credit card if the seller does not contact me with a prepaid return label. Using ANY automotive website, this Dorman 300-149 is the exact and correct part number and is supposed to have worked. The pulley looks brand new and not previously used or installed.

Does fit my 2010 6.7 cummins
This is the style pulley my 2010 ram with a 6.7 uses. I have no idea if the pump was changed or what, but fit and matched the old one perfectly. No more wobbly pulley. There are multiple style pumps/pulley/reservoirs, but if your uses the 4 spoke like this, not the 4 hole style, it will work.

8 rib, a must have for Dodge Ram
If you are converting your non-ZF Power Steering Pump (2006 Ram 2500) to the newer and better ZF Style Power Steering Pump, you must have this part! The old pulley will not fit on a ZF Pump. You must have an 8 rib pulley like this one also.

fits if you use the correct pump
This pulley is the correct one for the power steering pump with the bolt on back plate not the snap ring backplate
