PSD Idler Pulley

Not a good day for the old truck.. Lost G/P relay this morning, now I notice that the idler pulley is FUBR, along with the belt of course.



Credit side, I got it home, 60 miles praying all the way.



This is second one this year, about 10Kmi. Everything looks good and square, belt tensioner is about 15KMI old also.



Am I missing something?



Regards, Pete Arnold

Check the powewr steering pump shaft. I have seen a couple wear the thrust washers so that the shaft would push out under pressure causing the belt to run out of alignment. See idf the shgaft can be move axially with a dead engine or if it moves under drffering loads.

About .025 end play. Too Much? Any luck with rebuilt pumps?

Should be OK. Bad ones I've seen run 1/8" or more which is well out of specs.
