I have an issue with the eccentric bearing hubs for the front and rear bulk heads and the adjustable aluminum steering bellcrank. I just need to know which direction to turn the eccentric hubs to put tension on the belts and to to reduce the tension because i am using the empire mid-block and its seems like there is alot of drag on the the drive train. Lastly what can I do to the adjustable steering bellcrank to stop it from hitting the front belt.

Does the empire mid block have the intergrated front belt tensioner? If so, then you dont need to use that becasue the front eccentric hubs do the job anyway. Remember, with the eccentric hubs, you can swap the sides over which is what I do for either the front or back bulk heads so you should be able to get the right tension. Cant remember the settings I have at the moment, will check tonight.

Yes, the aluminum steering will hit the front belt. I have filed down those 3 different adjustment inserts, use a shorter screw & make sure I use loctite. Or just the standard plastic ones.

Need to think of the Empire front belt tensioner in a different way, it's main purpose is to hold the belt on the 16th pulley a little longer to keep more teeth in mesh to distribute the load over a greater number of teeth, so we actully run the cams so the belt is a little loose and use the bearings to pull the belt down slightly. Calling it a tensioner is actually a misnomer but as I've mentioned before "extra teeth in mesh thingee" would have been a real crappy product name.

Thats what I would've called it!

How many different upper front arm mounts are available?

Does anyone have a PDF of the parts list from the '05WC I can check out?

there are 2 plastic upper arm mounts from Kyosho- one places the hinge pin closer to the center of the car compared to the other.

there is an aluminum upper arm mount from Kyosho

Empire makes an aluminum upper arm mount as well

Sweet, thanks, didn't know if there were more than the 2 I knew of. So if I'm right the '03 upper arm mounts will lengthen the upper arm compared to the '05, correct?

darkangel

the 03 front upper mounts will shorten the arm compared with the 05 front upper mounts (which pushes the upper outward).

the empire version moves the inside front upper arm down 3 mm thus changing your front roll center (they have both the 03 and 05 version)

If the '05 mounts push the upper arm outward that would mean the arm would be shorter with them than the '03 mounts though, correct?

I might have to get a set of the Empire ones just in case I need the extra steering

darkangel

Physically, yes the 05 mounts will shorten the upper arm to keep the same camber/width. The only thing that really changes on the arm itself is the pivot ball.

Really the difference is where the pivot point goes. The 03 is closer to the centerline, as opposed to the 05 that moves the pivot point outward (if I remember correctly 5 mm). the 05 will have more camber change during a turn than the 03 mounts.

Ok, cool, just wanted to make sure I was clear. Does anyone run the '03 mounts still like on larger sweeping tracks or are the '05 mounts basically just the standard now?
