The kit eccentric is the "standard." The optional +1 eccentric is further offset from center.

So it is where the diff is located in the carriers ??(left to right)

How do you adjust this?

It does not move the diff left to right as that is fixed. The +1 eccentrics will make the "low" setting lower or the "high" setting higher.

See post #1211 here http://www.rctech.net/forum/electric...rpower-81.html

The eccentrics are Q&A by Paul L.

I'd rather quit racing than change the hinge pin blocks again. Is there some trick to it?

Thanks for the info on what it does, but how do you do it? What do you adjust? I must be missing something in the manual but I cannot find info on how to actually adjust the setting. Do you add shims, flip something, etc...

pretty sure its where the notch on the plastic part sits in the grooves onthe suspension holder....notch at 6 o'clock=high diff, 12o'clock= low diff

may be completely wrong but that's how i read it

Loosen the 4 hinge pin block screws then change one at a time, once done tighten the screws, check that the arms have no bind, re-set ride height and droop, go race.

Rotate the eccentrics to tighten or loosen the belts, I usually start one notch less than what the assembly book calls for. OR 2 notches, but run a external belt tensioner. Kit setting is on the tight side.

You are correct, although belt tension will dictate if the final settings are true 6 or 12 o'clock, the tension is more important than the reading. For the new guys make sure you rotate both sides of the eccentrics the same direction or the pulleys wont run straight in relation to the belts and idler pulley.

Page 10 of the assembly manual, section 2, central transmission info.

Nope, still don't get it. I have the manual in front of me and page 10 references the diff height and how to adjust the belt tension. The word eccentric isn't mentioned at all.

On all the setup sheets I have read it lists diff height and eccentric as different settings.
Diff height = highor low
eccentric = 1 or standard

The +1 eccentrics have the hole that the bearing sits in located 1mm offset from center different than the stock standard ones. The same as the stock ones are not perfectly in the center of the holder the +1 are even more off set.

You do know what eccentric means right? In this case its the red ring in the assembly manual.

The round plastic thingie that the bearings are in is an eccentric. You can run the diff high or low with the stock eccentric or a little higher or lower with the +1 eccentrics.
