| Subject: | C-145 lifter body face specs. |
Hello all:
We're overhauling a C-145 Cont. in our EAA affiliated Flying Club
airplane.
Our Lifter bodies (cam followers?) are in near perfect shape including
the faces which engage the cam.
We want to just lightly touch the lifter faces for renewal.
Could someone please advise what coarseness (grit?) of stone or wheel
would be appropriate for this?
We have run a dial indicator over the face and it is not flat. The
center of the face is 3 to 5 thousandths higher than the edge.
This appears to be a straight, rather than radius (concave?) cut across
the lifter face. Do we have that right?
Can anyone advise what are the Continental specifications for renewing
the lifter face? Angles etc.
We have a lot of machine shop capability. Any help is greatly
appreciated.
Regards,
Randy, Las Vegas

Well, Randy, not sure without seeing the lifter- BUT, I am reminded of
my family doctor's favorite expression - "If it ain't broke, don't fix it."
Sorry - couldn't resist.
Whatever
