Belt Tensioner Pulley
Old tensioner pulley rattles, tells me that the bearing is on its way out. Bought the L98 Dayco unit to rebuild my LT5 unit.
I noticed that the pulleys (old and new) are really tight fit to the Dayco post, but have a tiny bit of play on the LT5. Otherwise, things seem to be the same. Any thoughts on how I can fill the gap? |

I just put over 2,000 miles on this billet aluminum pulley with no issues. Sent from my iPhone using ZR-1 Net Registry |
Re: Belt Tensioner Pulley
I'm thinking about tensioners as well. My car got a little hot yesterday and I also noticed it wasn't charging very well. Poking around a little I noticed the belt seemed to have more slack in it than I feel like it should. The belt appears to be in good condition. Kinda thinking maybe the tensioner spring is not doing its job very well.

Rebuilt my Tensioner per issue 34 of HOB. Took care of the rattle noise, but I'm experiencing the same issue as Locobob.
On that topic, I found this: http://www.zr1.net/forum/showthread.php?p=241294 Possible that a new (shorter) belt could stiffen things up. :) |
Re: Belt Tensioner Pulley
I discovered that I can actually move the tensioner quite a bit just by putting finger pressure on the belt up by the power steering pump, I don't think it should be that easy to move.

The Force measured would be the actual force on the Belt Tensioner Pulley perpendicular to belt between Alternator Pulley and Harmonic Balancer. |
Re: Belt Tensioner Pulley
Here is how much I'm moving it with just one finger pressing on the belt.

I have no idea where you were pressing but am assuming you are pressing perpendicular to belt between two of the pulleys. I would say that is a very weak Belt Tensioner. I will go out now and press on my belt for ya :p OK....I pressed down with finger between Power Steering Pulley and AC Compressor and could not push hard enough to move Belt Tensioner pulley hardly at all. I then pushed down with my thumb pretty hard (maybe 10 pounds) on the belt and the Belt Tensioner Pulley moved almost as much as your video. If that helps you ;) Also......your Serpentine Belt is maybe a bit long (by 1/4 inch) making the belt tensioner stroke almost maximum with minimum pressure at maximum stroke. Just judging from the small space between the Belt section passing the Tensioner and the belt section going from the Alternator to the Water Pump. |
Re: Belt Tensioner Pulley
Yeah its rattling like a mofo too, the tensioner is definitely bad. What are you getting out of that fancy pulley Cliff? Is it just bling?
