Chip,
Thanks for that advice. I've been pondering as to where to place the jack
as well. In the past, I've used the lower tube of the front suspension and
the rear axle and found that, if I used a point on the chassis [the ladder
frame] roughly halfway between the front and rear wheels, the side rails
flexed more than I though they should (and gave me a good reason to consider
a new chassis). I have one question, though. You state that "the frame is
so rigid that he can jack up the front left by about a foot and all three
remaining wheels are still on the ground." To me that indicates just the
opposite, i.e., that the frame is flexible. If the frame were rigid, I
would expect that, ignoring the vertical travel of the wheels, more than one
wheel would leave the ground. Am I missing something?.
On this topic, what is the frame and what is the chassis? I get the two
confused. What do you call the ladder-type frame and what do you call the
ash body? Does a Morgan have a steel frame and a wooden chassis or is it
the other way around?
Thanks
Chuck

Well, now I am going to contradict myself and invoke the spirit of
An
Expert. This expert, who I trust implicitly on these matters, has
been
reading all of this email today , but he's a shy and retiring
fellow,
isn't crazy about computers, and doesn't seem likely to weigh in
here on
his own. Since I just got off the phone with him, I'll tell you what
he
says, but keep in mind that it's second hand information as a
result:
(1) Go ahead and jack it up by the dif. After all, these difs used
to be
used for Studebakers, and as long as they're 3HAs they're strong
enough.
The 7HAs (I think I have those model numbers right) are flimsier.
(2) Supporting Phil Roettger, go ahead and jack it up by the bottom
tube of the front suspension. It is the strongest and main front
support
of the car. If it can take potholes, it can take your jack.
(3) Don't worry about jacking it up via the cross member by the
gearbox.
This is where the factory jacking point is located.
Now, my shy and retiring buddy may weigh in here yet, and I advise
him
to do so. He also points out that on my car, with which he has some
passing familiarity, the frame is so rigid that he can jack up the
front left by about a foot and all three remaining wheels are still
on
the ground. No wonder it handles so well.
Once again,
Chip
