I have already replaced the water pump with pulley, belt tensioner, and have the bearings to replace in the 70mm & 80mm idler pulleys here soon. I have not had any issues with my PS pump and have replaced the fluid in the past 6 months and added Lucas PS conditioner at that time.

Is there some preventative maintenance I can do on the PS pump pulley? I have not worked on the PS pump on the D2 except to drain/fill PS reservoir to refresh with new PS fluid. So I am not sure if the pulley can or should be replaced, or it is just replaced when you have to replace the pump some day, or is the pulley something I can do as preventive maintenance at 150K mile like my other items?

 

Do it with the pump.
