I've been back and forth on this, and found not only conflicting data and answers, but strange geometric reasoning.
1. "the pad radius is the long (valve-side) lever arm length", but (if true) why are there so many shorter exceptions?
2. "the radius is the valve lift" (no reason given)
3. "as...
I'm trying to get a better understanding of how an L6 crankshaft is balanced (not what it does).
Searches turn up nothing useful, including such gems as "in-line engines do not have balance weights" (what's that big thing opposite the pin?), and that L6 engines do not require balance factor...
The newer Eaton MP blower no longer uses a simple triangle for a discharge port, like this shown on an older M62
But now resembles a NACA duct, like this MP62:
1. is this correct?
2. not only is the area different (perhaps smaller) and L/W ratio far different, and covers a different...
I've seen many comments that any reduction in tappet, pushrod or rocker short side lever weight has almost no effect on determining spring rate and RPM.
This must, IMHO, be due to the amplified movement of the long-side bits (valve, collar, locks, lash cap, long lever) by the rocker ratio...
I'm a complete novice with drive methods. I'm attempting to drive an Eaton supercharger at about 3X speed off the clutch shell of a motorcycle. The original Eaton drive is serpentine multi-groove pulley/belt, but I have no source for a pulley larger enough to fit around the clutch (min. ID...
