Reassembling this mallet, and I find myself unsure I have the eccentric (all 4 of them) in the right orientation.

From looking at pictures, I think it goes slightly to one side of the axel, but which side?

How would I know?

It's my Aristo USRA Mallet. Somebody told me it's a Y6.

Well, I couldn't really find a good detail photo. Looking close at this one, I think I have the ones on the fireman's side correct:

Here's how I have it:

Hmm. Looking at it again, I don't think I have it right. One leads the crank and the other follows it. Haven't looked at the other side. I suppose right or wrong, I might at least have all 4 alike

Not much point in testing to see if I have it right. The electric motors work however I put it

From Tom L's link, here's a clear photo. You can see the first set of drivers has the crank pin at the bottom and teh eccentric points forward.
