Re: Landfill harmonic balancer
I recently installed a balance ring system from Balance Masters to test out. http://www.balancemasters.comtoggle quoted messageShow quoted text
I can report that the balance ring system by this company DOES NOT WORK. For reference I used my Aces Electronic Balancer to test vibration out both before and after installation.
Unbalanced (no weights on flywheel) the Aces indicated .03”/sec balance. When the balance ring was installed the best it would give me is .17”/sec balance at 2100 and 2200 rpm.
I then took the ring off and balanced the engine/prop to around .02”/sec at 2200 rpm.. After reinstallation of the ring and the balance went up to .19”/sec which was quite a surprise. The ring never reduced the inbalance to anything close to what I was able to achieve to with the electronic balancer at 2200 rpm even after running the engine for longer than the specified 2 minutes at a steady rpm.
I did notice a possible reduction of vibration at cruise rpm, but it is only a seat of the pants estimate. It felt a bit different, but not $400 worth of difference in my book.
I returned the balance ring, rebalanced the engine/prop with the Aces, down to .01”/sec and saved myself some $$. I am not saying that a competitive or different type of balance system would not work, but in this case with this product, it did not.
