Question for the MRX6R guys is the in the clutch housing is there supposed to be 3 bearings or 2 because in the manual it looks like only 2 but I hear it has 3.

With the 6R comes a MRX6 manual with an extra inlayer of how to build the new parts.

I'm also replacing all 12 of the k0603 bearings which is the 10x15x4 bearing size with AVID bearings as they are sold by the each and are priced well. Has anyone tried these bearings in the MTX6R

No need to get mugen oils, all other brands will do the same.

But are you talking about the MTXR6 or the MRX6R or both? (This is the 1/8 MRX6R topic)
BigC2007 and 1/8 IC Fan like this.

The older MRX6 used two 5x10 bearings in the clutch bell. The newer 6R clutch bell housing uses 4 bearings (i think 8x5x2.5). place three of the bearings on the motor shaft and the fourth up in the clutch housing then put the housing over the shaft. Your clutch issue may be you do not have all four bearings in the clutch bell housing. Steel City will be open for practice this weekend (Aug 17-18). Not sure if I will be there. After a week in China, an 11 hour delay on the flight back and three hourd sleep Friday morning before heading out to the Wallace Motorsports Showdown over the weekend, my body is in sleep deprivation mode right now. Good thing I went back to work today so I can rest. :-O

Lots of different combinations. I run mine flat (same front and rear) and some run them nose forward (higher rear by 0.5 or 1.0mm) than front. I measure my car with my "set-up" tires cut at 72mm rear and 65mm front with ride height at 7.0mm front and rear.

Default MRX6R centax clutch setup

This is my first time of assembling a centax clutch after nearly 15 years of intermission. As I am assembling the 6R centax. on a Novarossi Mito 9, I found that for clutch gap with no shim the max I could get is only 0.4mm, can never get near to 0.6 mm as stated in the instructions at all. I did took out one of the clutch bearings and pressed the clutch bell all the way onto the shoes. I checked the thrust bearing orientation and it was right (heck I even put the bigger hole side of the trust bearing to the outside for a try). I disassembled and reassembled everything again, made sure the cone on the crankshaft was all the way touching the front crankshaft bearing, still no chance to make the clutch gap more than 0.4mm. I noticed there is a gap of about 1.5mm from the flywheel to the front crankshaft bearing. At the end, I managed to shim the whole assembly to make an axial play of around 0.2mm.

My question is, must the clutch gap be 0.6mm first, and then shim the whole assembly to make it axial play of 0.2mm? or its fine that so long as in the end the axial play is 0.2mm while the clutch bell could spin freely? Do I need to trim down the cone washer on the crankshaft to lessen the gap between the flywheel/front crankshaft bearing and to make the clutch gap to at least 0.6mm, and then shim the whole assembly to make an axial play of 0.2mm?

Thanks
