<p>Bill:</p>
<p>You wouldn't happen to have the flywheel weight for the H,
perchance? At a guess I'd place it at around 100 lbs, since an H
is slightly smaller than a B, but I've never seen the figures.<br>
</p>
<p>Thanks,</p>

<p class="MsoNormal">Interesting question and comment about
flywheel and crankshaft weights. And I’ve been wondering
about flywheel weights as I have a G and a 70 that need to
come apart sometime soon. As a younger man I would have
tackled them, but they’ll be managed with a hoist now. The
older I get the better I was…<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">The Deere Master Parts Index, last
published about 1970, has the weight of many or most parts, I
suppose to help in estimating shipping cost. An online
version of this catalog is available at
<a href="http://www.b2parts.com" moz-do-not-send="true">www.b2parts.com</a>.
If you use the online parts index, note that the user ID and
password are contained in the explanatory material at the
entry page.
<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">Anyway, following are weights for a
sampling of 2-cylinder engines. I tried to use the later
models for the letter series, although the entry for some of
them was missing the weight information so I reverted to an
earlier model of the same tractor. <o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">Regarding the crankshaft weight
contributing to the inertia, remember that the flywheel
inertia is a lot more the further the weight is from the
center. Thus although the crankshaft is substantial in
weight, it’s close in and doesn’t contribute proportionally to
the flywheel effect. The D flywheel below isn’t one of the
heavier ones but as I look at my D the flywheel is
substantially larger in diameter than any of the others.<o:p></o:p></p>

<p class="MsoPlainText">110 lbs for a Deere flywheel seems about
right. The weight of the flywheel is almost independent of the
engine size...730 flywheels aren't much over 100 lbs either.
Apparently as the engines get bigger, the extra mass in the
crankshaft provides enough moment of inertia to keep things
running. Does anyone here remember how much the crankshafts
weight in various larger two-cylinder engines? I know they
aren't featherweights, given that the rod journals on a
620/630/60/G are about 4" in diameter.<o:p></o:p></p>

<p class="MsoPlainText">My recollection is that one stout feller
can take one off, but it took two of us to put one on! The
only task I can remember that was worse was replacing the main
reduction gear, which on a 730 is 'interference fit'
<o:p></o:p></p>
<p class="MsoPlainText">- you have to heat the gear in hot oil
to get it to slide onto the crankshaft! It's probably the same
on the 620/630 but I didn't happen to be around when they (Pop
& Grandpa) rebuilt that one. I do have a used<o:p></o:p></p>

<p class="MsoPlainText">> My bet is that you’re correct and
that there is some displacement and that nut indicates it is
where the most displacement occurs. That’s probably why the
cracks and why the nut is beat up. Do you know what it was
hitting against? I’d take a good look and see what it was
hitting to make sure nothing else is damaged.<o:p></o:p></p>

UPDATES<o:p></o:p></p>
<p class="MsoPlainText">><o:p> </o:p></p>
<p class="MsoPlainText">> Well, gents, I have another update
in the long saga.<o:p></o:p></p>
<p class="MsoPlainText">><o:p> </o:p></p>
<p class="MsoPlainText">> Let's begin with the '51 A. I
acquired a mesh nozzle to go over the inlet of the sediment
bowl so that I could pull the lawnmower tank off the side (I
was afraid of catching it on a tree limb while working) until
we can pull the tank to clean it right. It is a tall, fine
mesh that keeps the crud out, and, when we used the tractor,
it worked very well: plenty of gas, no clogging the inlet.
Not the permanent solution but a workable one. Tractor did a
great job finishing up the brush-hogging. I still need to
replace the points.<o:p></o:p></p>
<p class="MsoPlainText">><o:p> </o:p></p>
<p class="MsoPlainText">> Now, the '49 A. I thought I had
bought a set of points for it, but I was wrong. I did get a
cap, however, and, after cleaning up the old points as well as
I could and replacing the gap, we had a good spark. The old
boy cranked up on the third or fourth revolution. Spiffy!<o:p></o:p></p>
<p class="MsoPlainText">><o:p> </o:p></p>
<p class="MsoPlainText">> We pulled it out to run it some,
and it seemed that there was a hammering in the engine. There
has always been a sensation of that, but it seemed obviously
more apparent to me. We did just a little work, but it seemed
to be getting worse. Also, the clutch was smoking when it
was disengaged. No slipping, no noise, and it snapped in and
out just fine, but, when disengaged, it smoked. So we parked
it. Today, I had my son pull the flywheel cover off today,
and we discovered the hammering problem (at least I'll bet):
Two cracks. If the pic comes through, you should be able to
see them near the lower, right nut. there is obvious
displacement of the casting, so I'll bet that puppy is loose
on there.<o:p></o:p></p>
<p class="MsoPlainText">><o:p> </o:p></p>
<p class="MsoPlainText">> So now we need to change the
flywheel. Fortunately, I have one. We just need to figure
out how to handle it (and also to set it in place correctly).<o:p></o:p></p>
<p class="MsoPlainText">><o:p> </o:p></p>
<p class="MsoPlainText">> Briefly on the '47 B: We need to
test the starter and reinstall. The generator is probably no
good, so we'll just disconnect it. I want to put good batt
cables on it. We'll probably work on it as we prepare to
replace the flywheel on the '49.<o:p></o:p></p>
<p class="MsoPlainText">><o:p> </o:p></p>
<p class="MsoPlainText">> It's always somethin', ain't it?<o:p></o:p></p>
