Need help figuring this one out. Ever since I installed the new Balmar alternator kit 621-VUP-MC-100-SV I am getting a lot of belt dust. Here are a couple of pics after 1.5 hours of motoring:
And here is some background info:
My current suspects are:
Any advice will be greatly appreciated.
And here is some background info:
- External regulator belt manager is set to 60%. I have not yet dropped my lithium in and, so anyway, my two flooded will not take more than 40A. High loads should not be an issue.
- Initially I blamed the dust on a misalignment and, indeed, the alternator pulley was off by 0.16". This was fixed by machining a custom washer and cutting saddle insert down to a correct size. The length of (alternator foot + insert + washer) is just long enough for a friction fit. This did not help. I have not measured angular misalignment but it looks good to the naked eye.
- The original 3/8" mounting bolt was replaced with M10-1.5x90 as required for Balmar.
- The Dayco 15400 belt is supposed to be the "best" for this application.
- Tension was adjusted/tweaked a couple of times with no improvement.
My current suspects are:
- The pulley or belt is wrong. I believe Balmar single-V pulley is a universal fit for both 3/8" and 1/2" and Dayco is 7/16". Other ppl reported good results with this belt. Maybe I received alternator with a wrong pulley?
- The belt is a knock-off. Not likely: "ships from and sold by Amazon".
Any advice will be greatly appreciated.
