I'm about to put my front cover back on, torque the bolts to ~15 ft/lb.

Can someone tell me how I'm supposed to put the front nut on? I'm looking at an allen plug, nut, washer, and residual silicone goop that used to be there. Where do I apply the silicone? What's the torque spec for the allen plug that goes into the center of the e-shaft and the main nut that holds the whole thing?

 

morning bump!

 

Anyone?

 

Got the info:

For OEM 20b eccentric shaft: per Mazdatrix, nothing between pulley hub & front nut. Just clean up the surface and tighten the front nut to 310-330 ft-lbs.

For GURU shafts: per XtremeRotaries, allen plug should have sealant put on the thread and tighten to 12-15 ft-lbs. There is sealing washer between pulley hub & the main nut. Use three bond sealant 1211 at the undersurface of the e-shaft nut then tighten the front nut to 190 ft-lbs.

 

You might want to double check your torque spec for the front nut...10 years on the floor says its incorrect

 

the OEM or Guru nut specs? which one is incorrect? Guru information is directly taken from Xtremerotaries email replies.

 

Mazdatrix - that spec is more like the rear nut to hold the counterweight on

 

I'll double check with them. Can you confirm there is no sealing washer between the front nut & the e-shaft for OEM assembly? That's the only thing I wasn't sure. Mine originally came with a crush washer but I was told there should be nothing between the main front nut & e-shaft. Thanks!

 

I don't recall there being one on mine, exploded parts diagram shows there being one, and as a rule of thumb - if it was on there when you disassembled then it should be going back on.
It might be a deleted part depending on what number 20b you have, mines a D series
