I saw a post somewhere that mention someones lack of enthusiasm over the way the center pulleys mount to the spur gear. I supposed there was concern over the strength of the plastic threads holding up.

So, I though I would mention the note about reaming out thee mounting holes in the spur gear. This "note" in the manual would be easy to miss of you are not paying attention. I actually missed it myself on the first build.

Anyway my point is make sure you ream the spur gear. When properly done this makes the assembly feel quite solid which will likely eliminate any worries over the strength of the threads. Also keep in mind that there really should be no significant amount of lateral force on this assembly which eliminates any need to put any torque on these screws.

Cool, thanks. I've noticed the 416 diff screw/thrust/spring/t-nut seem to fit well. If it clears the CVD, I may just use that. I'm a fan of the spring and caged thrust.

I like the layout ... Power on one side and motor on the other ...

You are welcome, thats how it was explained to me when I asked the same question Monday night to a pro-driver....

Okay so.... What about 13.5 ? ()()()() TO (((((( or something in between?
No slip no strip are both important so.... (((((( for 13.5 as well?

try this:

Multiple Belleville washers may be stacked to modify the spring constant or amount of deflection
Deflection

Deflection or deflexion may refer to:*Deflection *Deflection *Deflection *Electrostatic deflection*Deflection ...
. Stacking in the same direction will add the spring constant in parallel, creating a stiffer joint (with the same deflection). Stacking in an alternating direction is the same as adding springs in series, resulting in a lower spring constant and greater deflection. Mixing and matching directions allow a specific spring constant and deflection capacity to be designed.

Example: 1 Spring is considered to be 1 in Parallel, 1 in Series. (This notation is needed for load calculations)

If n = # of springs in a stack, then: Parallel Stack (n in parallel, 1 in series) - Deflection is equal to that of one spring, Load is equal to that of n x 1 spring. i.e. Stack of 4 in parallel, 1 in series will have the same deflection as that of one spring and the load will be 4 times higher than that of one spring.

Series Stack (1 in parallel, n in series) - Deflection is equal to n x 1 spring, load is equal to that of one spring. i.e. Stack of 1 in parallel, 4 in series will have the same load of one spring and the deflection will be 4 times greater.

So six of one and a half dozen of the other ... LOL
Looks like (((((( would be the way to go but the adjustment will be sensitive.
Or did I read that wrong?

(((( is a hard spring

((() is a medium spring

()() is a soft spring

()()()()()() is really soft

all just depends on how much slip and play you want in the adjustment
