Subject: rear main leak advice

My Eldo has developed what appears to be a rear main seal oil leak. I would
like to know if this can be repaired with the motor in place, by pulling the
trans, or does the motor and trans have to come out as a unit to repair. Any
help would be appreciated.

I've done it both ways, and each is about the same in
terms of effort, although you don't have to remove the
engine from the frame. If you don't have the "special
tool" for removing the swingarm bolts (the ones with the
two holes for pins, John Chicone produces a nifty tool for
this), its probably easier to put a jack under the pan,
remove the engine mount bolts and generator, coil,
mufflers, etc. and slide the engine forward in the frame.
That will give you barely enough clearance to get the
boot off and and get another one in there. Ted's right,
the whole job will take you about 4 hours.

No special tools needed, but it isn't real simple. You
have to either pull the motor and transmission or remove
the swingarm to get the boot in there. Figure a couple of
hours to get it off and a couple to get it on.
I wish someone would create some sort of quick-release
motor/transmissions mounts.

Great Ride to/from the National but had a few issues
shake out. As John
P mentioned in his post, my charging system was not
charging and I did
not know it as the dash light was slightly lit but not
enough for me to
realize. At 250 miles in, the bike stalled and cranked
slow. At 300
miles, she completely died at a light on Rt 30, no
lights, no nuthin.
Swapped batteries with Cam (all credit given to Dave W
for this idea)
and made it the last 100 miles to the hotel after a
total of 13 hours
after leaving home. A great Guzzi guy named Wes helped
me trouble shoot
the charging system at the rally site and it turned out
to be a bad
voltage regulator. Swapped it out and all was well.

Other bigger issue I had was a leaking split driveshaft
boot (just
replaced it before leaving for the National). Don't
know why so much
oil is getting in there and leaking out, but thank God
the battery died
along the way cause when we stopped, I noticed gear oil
was spued all
over my right muffler and all over the entire right half
tread of the
rear tire. Would have been lights out if I went around
a right hand
sweeper! Mark E said the clamps I was using were too
big, so he used
some zip ties to try to stop the leak. Front one
worked, rear one did
not. In the link to the pix I sent earlier, the 1st pic
is what I did
to the boot to keep it from leaking oil on my tire
during the ride home.
Worked great! So, my question is, I plan to rip the
rear apart to
replace the split boot with a solid original one. What
else should I
check along the way, i.e., is there something that
limits the migration
of gear oil out of the rear drive? I'm pretty sure
that's where the oil
is coming from as the tranny oil level is perfect, but
the rear drive
oil was a little bit low. Also, is there any special
tools needed to
take the rear end apart to replace the boot?
