Oil leak out of eccentric shaft bolt

Hey guys, 1987 FC Rx7 TII,

I have an oil leak from my eccentric shaft bolt. I recently took the front cover off to replace the oil oring because I had low oil pressure. When I assembled everything, I never put a new crush washer in around the eccentric shaft bolt. Pretty sure thats where my leak is from. I have a new crush washer coming, but have some questions.
  1. When installing the new one, I should push the clutch in so the front stack doesnt fall apart, correct?
  2. Ill torque the new washer to spec, will I have to recheck my end play?
  3. Any other washers or orings that I am missing, oil is coming out into the pully where the eccentric shaft bolt goes

There's an o-ring on the tip of that bolt (https://www.atkinsrotary.com/Rotary-...b-Bolt-O-Ring/) that you should change that along with the copper washer. You should keep the clutch pedal depressed and as long as you don't move the hub, those thrust bearings will not slide off the spacer. Before reassembling, you should measure the protrusion of the e-shaft in the hub to ensure that it meets the 2.44 mm spec.
