I did not, that's a good piece of information for future reference.

Keep in mind, though, that in this particular case the belt didn't fail or display any signs of premature wear. It just didn't fit.

I find the Continental belts fit best for this application. I think Gates makes the Gaterskin which is the only belt I've found that doesn't squeak during shut down of the Cummins.

A "boost boot" can be made to hunt down boost leaks. It is likely not necessary on a 617 because there aren't many places for a leak to occur.

Give your power steering system a good flush and filter change if you haven't lately. PS is one of the frequently neglected systems that contain fluid.

Can't agree more!

It doesn't seem to get much louder at full load in lower gear. As you can hear at the end of the video, it can also wind down as the car slows to a stop.

Driving w/o the belt surely wouldn't hurt the p.s. pump. I could put more stress on the input side of the steering gear, though no issue in highway driving and I think the same force goes thru the recirculating balls either way, the driver just needs to apply more force to turn. 1" deflection under thumb pressure is way too loose for any V-belt. I recall normal is something like 1/8" w/ 10 lb pressure if pulleys are 12" apart, but sure you can find a spec. The FSM probably has some delicate procedure with a calibrated spring, while wearing a pink tutu.

Since you changed belts several times, I expect you found all the bolts to loosen for adjustment. As I recall, there are two clamping bolts and one at the pivot to loosen. Once loose, you should be able to freely rotate the p.s. pump by hand. If you need a pry bar, you didn't loosen all. I always slide the new belt on, pull up on the pump until tight, then check there is still plenty of clearance left in the slot. I then work with the tensioning bolt.

The Gates belt would have to be pretty far off nominal to not leave some adjustment. On any car, if you ever find the factory belt won't work, it is easy to find one longer or shorter. You can download a Gates belt catalog and thumb thru it. As I recall, there are 3 different widths and lengths (circumference) come in 2" increments. Once you have the Gates PN, you can cross-reference to any other brand. I sometimes use the "Gatorback" belts with there diagonal "teeth" since claimed to give less noise, but can't say I notice a difference, but any bling is nice.

Nah, not a boost leak.

Hmmmm. That sounds almost like a differential whine or something. Can you tell if it's coming from the front of the car or the back?
