DEFINITELY determine if it's the Camshaft Synchro--aka the link which DRIVES THE OIL PUMP! An engine killer!

Just remove the serpentine belt entirely. It will not harm your Vulcan--esp. if cold--to run for 60 seconds or less w/out the belt. This will also remove all of the fan/alternator/water pump/AC clutch noise, and make the dying cam synchronizer stand out even more--if that is the problem.


RE: PULLEY ALIGNMENT(S), if you don't have access to a LASER, a metal yardstick is good enough.

Hat tip to McCormack @ TRS for pointing out that the tensioner design is a bit lame from the get-go, and persistent squealing is often due to the tensioner getting just slightly out of true with the crankshaft pulley... again, the EDGE OF A METAL YARDSTICK tells the tale...

... if your tensioner IS out-of-aligment (even if new), you can shim it back to true by removing tensioner and re-installing w/ very thin washers on the alignment stud... on my to-do list.

If you don't know when your cam synchro has been replaced I'd go ahead and take care of that. My truck had a squeal as well and went away after the cam synchro and sensor were replaced.

Yep. You want your oil pump to keep turning.

I am having the same problem is there an estimate of how much it would cost to replace the cam sync and sensor?

Go on rockauto.com. you can get both the synchronizer and sensor for around $130. That's all it will cost if you plan to do it yourself, it's pretty easy to do

Definitely be careful if you're going to replace the synchro yourself and don't have the special ford tool to do it. If you're off by even 1 degree when inserting it, the synchro can shred the sensors magnet and you'll have to start from scratch

It will only be off by a tooth. The cam sync is driven by a toothed gear, and fits into the oil pump shaft with it. If you're off by a fraction, it will fall to the next available tooth and will be off by the angle margin of whatever one tooth is. The internal shaft in the synchro should never be off track enough to smack the sensor unless the shaft has worn enough to wobble. Alignment doesn't do this however.
