[NSRCA-discussion] YS Problem

[Jon Lowe]

I had a bolt break in two, no kick, and I had the same thing happen.  
Was the end of your bolt still in the adapter?  I now change bolts 
semi-frequently.  Of course it had to happen in the middle of a judged 
round, Jason Shulman was judging and saw it, so I zeroed the round from 
that point on.

That’s OK..I lost an almost brand new spinner tonight.  Didn’t
have a YS kick to do it..I guess the bolt wasn’t as tight as I 
thought…just the
cone came off…3 week old anodized Tru Turn….grrr….

Speaking of YS and fun, I am pulling a half the niter converting
   my Black Magic to electric... Hmmmmmm Let me tell you, it was NOT fun 
trying
   to get the nose ring out, damn that thing was in there good. Other 
than that
  it is going fairly well actually almost done staring at it.

In
  a word…  Crap!


 


Anyone
   else??  I’d
 like a second opinion!!!! (nothing personal Anthony but 
your
  opinion ..well…sucks. lol)   I have a feeling you’re correct
  though, much to my chagrin.  Not having a good YS moment.

Mark,




Bad news, you can not put that back in so it does not pup out again.
     From what I have read, that problem isn't really user serviceable. 
I have
     read posts of guys pressing them back in and even some guys using 
JB Weld
     to keep them in. Usually that is a problem that requires the engine 
to go
    back to YS.






 






Sorry to hear that!






 






Anthony

The short version…    YS1.70DZ – the brass fitting on
     the TOP of the head (towards the back) that has the black check 
valve
    pressed onto it blew out of the engine in flight!!  Needless to say
    the motor quit.


 


It appears to be a pressure fit.    I pressed it back
    in (I knew this wouldn’t work, but what the heck), started the
    engine.  It idled great, ran up great, took off, and as soon as the
    motor warmed up (about two passes, pulled vertical and POP…dead as a
    rock.  Landed… and the fitting had popped out again.


 


So I have a few questions…


 


What caused this to pop out in the first place??


What do I do to put it back in SECURELY


 


HELP!!!!
