Yup already replaced. Tighten every round just in case.

Default RONALDS SETUP

Hi,

Just downloaded this from Team Yokomo FB page. There is text to go with this setup. Mainly deals with adding weight to the car to get it up to legal weight. Either placed in the middle of the chassis or to the side.

I have included the link for the page and a copy of the PDF file. Also talks about 1mm and 1.1 mm piston holes. It would be easier to access the FB page and read for yourselves.

http://www.scribd.com/doc/115525617/Untitled

Hope it helps someone.

Regards,

Calvin.

I've ran into this problem.
whats happening is when you tighten the left side, the spur shaft isn't exactly perpendicular, so effectively you are screwing it in on a slight angle...

to get the screw out, you have to hold down the spur shaft with pliers, and screw it out the screw.

once you screw it out and attempt to remount the spur, if you notice any resistance in the screw before fully being screwed in, its at an angle, and you will have the same issues...

make sure you shims are flush to the shaft ends...I noticed different spurs have slight different widths, so the supplied shims dont go flush to the ends of the shaft with different spurs. They must be flush.

follow this, and you will be fine.

Default Binding Bearings

I also noticed that I've been getting bearing binding issues..

I came to the conclusion that the yokomo hexes are the problem. when you tighten your wheel nut on tight, especially serrated ones, this is where the binding happens...

to trouble shoot, I tested tamiya 5mm hexes and had no issues. just added a 0.1 mm shim to get rid of the play.

the Yokomo hexes really pull in the pin and put a lot of pressure on the centre of the bearings.

what I found helped was adding tamiya 5 x 1.5mm shims inside between both bearings inside the hub. This helped prevent the yokomo hexes from pushing the center of the bearings too tight causing binding..

Shim part # is 9804372.

Cheers,
Chris.

Calvin thx for the data. I haven't read the word doc.. But I can tell u that setup doesn't work for stock racing. Way too much steering. I've run three very similar setups to that already. Id imagine all of that steering is what makes the car so good in mod racing. Makes me wanna drop a 4.0 in it...
