Sepentine belt question.

Hopefully there is a parts guy on here who can me.I replaced my vacuum pump back in May.Now it's starting to make a little noise like it did before. So I 'm thinking that it wore out way too soon.I've had the truck a little over a year and when I bought it the last owner included new air,fuel,filters and new sepentine belt.I checked the receipt everything matched,so I changed everything with the new parts in Oct.07. New pump was needed in May 08. I decided to check on line to see if my Dayco belt is the right one. Two places I checked online say I need Dayco 5081190,I installed Dayco 5081195. Does any one know what the difference in the numbers are.Belt went right on and seams to have the right tension. I just want to make sure this belt is not causing my pump to fail. Thanks

no clue on the belt, most manufactures have the length differences as the last few digits of the part number. its probably a hair longer or shorter.

The belt you put on is 119-5/8 inches and the one you don't have would have been 119 inches.

Did you put any grease/oil in the bearing on the back of the pump?

Thank you for the info on the belt. And no I didn't lube anything on the pump. Didn't know I needed to .I just pulled the pump off,and pulled the pulley off and swapped it to the new pump. Then bolted it back on. I didn't see in my manual about lubing anything. What did I miss ? I'm still learning about the 7.3. Thanks

There's a set of bearings at each end of the shaft, you cant do anything with the front one but at the rear there is a plug (bolt) that you can remove to add a mix of grease and 90W gear oil.
