My neighbor gave me a fairly nice 10 year old john Deere made Scott
mower that is a fairly heavy duty model with 54 deck, took care of
my need to buy a new mower. It was using about a quart of oil an
hour. It has a Kohler command engine and quick search turns up it
had bad head gasket or 2. I

I remember shooting an old battery
with a 12 gauge shotgun back when I was a young fellow. It
was probably 50 or
more feet away from me

Break in an internal bus bar in the battery?
Hit the starter and turn the battery into an arc welder.

Had to be that, it's consistent with the earlier behavior.
The battery had suddenly been acting 'weak', it could
barely turn over the car, yet the voltage was just
fine and it took a charge
The jouncing the car took during Jill's off-road adventure (see
http://userweb.windwireless.net/~jimc/JSL2log.html#14Sep2008) was
probably ultimately responsible for this, though it was only
yesterday that I noticed anything odd about the battery.
That battery had had a hard life, what with the

There must have been hydrogen gas and a spark. The hydrogen gas
may have been in the battery box from when
Jill called me at lunch from the library parking lot, and said that the
560SL battery (that went through Hell with the alternator incident) made
a big 'pop' noise when she went to start the car, and fluid started
dripping out of the back. (It also wouldn't start, and had been
getting difficult

And, IIRC, charging voltage was reasonable when you tested it.
I'd still test the charging just to be safe.

I had a battery on a piece of equipment blow up in my face many moons
ago. We had jumped the battery, and when we disconnected the
jumpers, the spark ignited the hydrogen gas from the battery, which
was now charging.
Ever since then, I am very careful to hook up the last connection as

It was 14.03V when I tested it after putting the new one in.

Reassembly time! I cleaned the shafts of the rotor and put it in the
freezer, and put the bearings and housings in the shop oven at 200
degrees F. They just slid together after that, with only a little
tapping with a hammer and some deep sockets to seat the bearings fully
in place on the rotor.
I slipped the old front bearing back on part way, wrapped a strip of
pop can metal around the back shaft, and chucked the rotor into the
drill press as a vertical lathe, with the front bearing resting on the
table and the shaft protruding through its central hole. I then got
out a flat stick and
I forgot to mention that I picked up the new bearings yesterday
at the local bearing supply house, $15 for the pair. I got a
USA-made (?) brush pack for $30 at an alternator rebuilding place,
they didn't have any solder-in brushes and I was tired of looking
for them.

The fallout from the dead 560SL battery in Missoula has so far been
a cleaning and gluing together of the battery box and lid, which were
well shattered by ham-handed past battery work. But yesterday I
finally got to pull the alternator, and one brush was notably short,
and arcing had chewed its
Great writeup -- you need a camera to take piccies to document your work

I have a dead alternator (I think bearings seized, have not fooled with
it) from the boy's 84 SD, maybe I should try to resurrect it. I'll
follow your writeup and take pics.
