Hey all,
Yup, yup, long time no hear. still fighting the ins. co. over the Ambo.
can you believe it? I think it might be time for a letter from our
lawyer friend, heard that works.
Anyways, Among the other million and one things happening, I have an
Eldo engine that had the generator bracket holes blown out. What I did
was built a whole platform for the bracket to live on (including filling
the old holes) out of that "welding putty". I was gonna just drill, tap
& helicoil new ones with studs locktited in. Then I came across some
time-serts. For those that don't know, if any. It's basically a hollow
metal sleeve, threaded on the O.D. and threaded through the hole in the
middle. The O.D. threads on the ones I got are 9/16-13 (or 12, can't
remember now). This will screw into the platform,then the bracket will
bolt to the middle part of the time-sert with 3/8 studs.
I measured the hole depth of the original holes (that were already
welded once, then blown out again) this came out to .420" - .430". This
seems pretty shallow, of course the tip of the drill bit digs deeper
than the outer rim. right now I am at the .420 - .430" at the tip of the
drill bit.
It looks as though there my be an oil channel running along the top of
the engine from rear to front, right down the middle. I cannot confirm
this, therefore I don't know if I can drill deeper. I have the top of
the supposed oil channel at a depth of .520"(aprox.), if it is an oil
channel I would like to leave some meat there, and stop where I'm at, if
not, if it's jus part of the webbing I would like to give the generator
bracket holes more beef.
Any ideas?
Thanks,
Kev
