If you noticed it has a spring loaded tensioner just for that reason, To keep things from wering out so soon. I would say that it was time for the bearing to go out.
if there is any play at all in the bearing on the tensioner,it needs replacing. also if you hae the correct new serpentine belt and the tensioner does not keep the belt tight when installed properly,you need new tensioner
could be that one of the belt driven components, such as power steering pump, alternator....etc, has a worn internal bearing. Reason being, is when the new belt is replaced, the tension is usually tighter causing more stress on the pulley and bearing.. Tom
As far as I am aware: Tension, Compression, Shear, Bending, Bearing.
The serpentine belt should be self-tightening if the appropriately sized belt is properly installed. If the correct belt fails to acheive the proper tension, then the belt tensioner should be replaced.
The Tension Capable Bearing can accommodate structure vertical loads that vary from compression to tension during seismic movements. This bearing can substantially reduce structural framing costs by preventing uplift of a primary structural member, and can eliminate concerns regarding potential structure overturning or large vertical earthquake motions
It is possible that on a 1995 Suburban K1500 4x4, the voltage meter being in the red means that the alternator is not charging or has an ungrounded wire. Also check the tension on the alternator belt.
Possibly loose belt or bad bearing(s). Check tension first.
It could be the bearing in your tension pulley.
You don't. The pulley is pretensioned by the manufacturer. If the belt tension is incorrect, the pulley must be replaced.
There is no fixing it. It must be replaced.
My suburban has a automatic tensioner therefore I need to do is take the tension off with a long wrench and slide the belt from underneath it and replace it with the new one. The tensioner is right by the water pump. If not then you will need to loosen the alternator bolt and drop the alternator to loosen the tension. Trust me manuals can be your best friend!!
No, tensioner pulley is at a preset tension, no adjustment can be made. If there is slop in the belt, the spring loaded tensioner should be replaced.
