I guess the engine is still together? Engine out of frame? I would
remove
the engine for this. It'll be a PITA enough if the cyl. are still on. I
would use breakcleaner, mineral spirits with a parts cleaning brush. It
would help if you have an air compressor to blow off the engine to see
where
your at while doing this also. I had the engine totally apart, bare
engine
case, cleaned it with mineral spirits, then blasted it with walnut
shell.
I looked at the case very close last night. Could not see anything that
would show what I was asking about to be an oil channel, so I went for
it.
The frt. hole turned out great using the time-sert, I think I will JB
weld
the OD treads of the time-sert lightly, to act as a super locktite. I
think
it will work pretty good. I have to redrill the rear hole. :-(

Sounds good, but what do I clean the case with to assure good bonding to
the case?? It won't do any good if it don't stick!!!

hey Tom,
Sorry I don't remember the name of the brand I used but it was a putty.
Once
out of the tube, I mashed it together, all in one, when it gets mushed
together it activates it. Since it is a putty, its alto easier to work
with
than JB Weld when building up material.
Like I said, I built a platform for the bracket, filling in the existing
bolt holes and in between the webbing. Then set up the gen. in the
pulley
and set everything down on the newly created platform. Oh, I placed a
piece
of plastic between the bracket and the platform, so the generator
wouldn't
get "welded" to the platform. Once dried, I lifted the plastic and I had
a
engine case that was molded to the gen bracket.
Defiantly use studs, redlocktited in the new holes(with helicoils,
time-sert) with lock washers and ny-locks. I think D. Richardson hits on
this also.

The gen bolt holes on my Eldo project are completelu gone...Trashed. I
want to build them up(somehow) and retap the holes or mount threaded
studs in there.
What would be a good material for filling these former holes???
Thanks!!!

Hey man,
Yeah, she's probably forgotten me by now, sitting there in the corner,
collecting dust.
Did all that already, the dowel is a good fit, I will take another look
at
it though, If it's at all shot I will take you up on the dowel. I did
fill
the whole area where the bracket sits, came out pretty damn good.
Like I said, I was gonna go with helicoil, decided to try the
time-serts,I
was thinking that the gen. mount studs could be bolted into something
harder
than aluminum, granted the helicoil would give extra ummph but the
time-sert
seemed as though it would disperse the load even more seeing as how the
OD
is a bit bigger. we'll find out seeing as though the holes for the
timesert
are already drilled. I just need to know a depth. I stopped at .420". I
would go a bit deeper if I could, just not sure if that's a oil channel
or
just webbing running along the top of the engine.
Did you, have you gone to the shop breakfast? Chris told me about it
but, I
work very late 3-4am on Fri & Sat nights, so I might be hard pressed to
get
there.

Hello Kevin,
Saw the poor ,sorry bike just the other day . The fellow who owns that
yellow 1974 Ducati 750 is a pretty swell lawyer/biker . He may be able
to refer you .
As for the generator base : there are a number of items that all
contribute to sucess . The little locator dowel must FIT tightly into
the hole in the case and securely into the threads in the generator . I
make up oversize locators and ream the hole for a good fit . The waffled
area the bracket sits upon lacks sufficient area to support the load . I
like to fill the area with metal filled Devcon or similar . Use STUDS so
you can get full thread engagement . Use a large ,hard steel plate
between the bracket and nuts to spread the clamping force . Also of
coarse avoid fine threads in the soft material . The Timeserts are a bit
large on the OD and Helicoils allow thicker walls to remain abit of a
trade off . Also the Helicoils give more flexibility in length .
You can call me if you want come over and use the lathe etc. I'll be
glad to give you a hand out here in Utica .

Hey all,
Yup, yup, long time no hear. still fighting the ins. co. over the |
|
|
| | | | | | 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 |
|
|
| | | | | |
the old holes) out of that "welding putty". I was gonna just drill, |
|
|
| | | | | | & 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 |
|
|
| | | | | | 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". |
|
|
| | | | | | 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 |
|
|
| | | | | |
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, |
|
|
| | | | | |
not, if it's jus part of the webbing I would like to give the |
|
|
| | | | | | bracket holes more beef.
Any ideas?
Thanks,
Kev |
