I wish to concur with what Ken B. reported. This was my second  Hamilton Work Rally and I had more fun this time. I think I got dirtier too. I don't think Ken mentioned it, but with the help of both Jims, I put a set of thick body pads on my coach as well as doing the torsion bar adjustment and ride height set up. My coach wound up with a 25lb difference in the front with the drivers side being the lighter. It drives sweet.
I must say, for those who need work done and don't have good work space at home (like me), this work rally is a blessing. If this small Rally fits in to your schedule next year, and you don't lack the work ethic, you won't lack for help if you need it, so put it on your schedule. Jim Miller will be on the Forum early next year with details.
Life is good driving a GMC that goes straight.

I think we all got dirty hands and dirty feet this year.

The trees shedding there blooms was the topping on the cake much like the
mating peacocks at Calhoun. It doesn't get much better.

I am embarrassed to show my ignorance but I can pass it off to being a new owner. What is a pork chop?

Wayne,

No need to apologize, a pork chop is the part at the rear end of the torsion
bars that is used to set the tension on the torsion bar which in turn sets
the ride height.

Go to the Parts Book 78Z Page 1-10 Key 38 and you'll see why they are called
a pork chop.

Thanks Ken, for the report. I saw your coach on the pit in some pictures I got. Wondered what you were doing to it. If Jim gets details out early Teri and I will try to be there next May. I just had too much happening here to make the 450 mile trip up. Maybe Ken B. will bring his scales again next year. He is a worker.

Pork Chop: a device shaped like a pork chop that mounts on the rear end of the front suspension torsion bars, the stationary adjusting bolt pushes against it to set the preload on the torsion bars which control front ride height and weight balance.

Center cut variety, too. Absolutely no fat.

The big end has a hexagonal hole in it. The torsion bar goes in it.

On my coach the lower portion was chewed out somehow. Once replaced the
front end ride came back to within 1/4 inch of spec. It was lower two
inches.

If Ken hadn't checked the ride height I wouldn't have known. If the employee
at the alignment shop hadn't looked into the situation, we wouldn't have
suspected the pork chop (torsion bar adjusting mechanism) to be bad.

I got an education with regard to this variety of pork. I like the other
much, much better. At least you're teeth don't break when you sink your
teeth into a tender one that's been slowly grilled to perfection. (Which is
one reason I'm glad I'm a Baptist.)

Thanks.. arm-anchor, torsion bar. Do they have a rubber insert that weathered? How does one fail?

After it was replaced we had quite a discussion on the reason for this failure. I and others have a few ideas on the cause of the failure but at this point until we talk to some more knowledgeable people I think we should post the theories.

I will state that the torsion bar was pulled part way out at one time and the hex area was shattered for about 1/3 of the way in. Our Indianapolis parts source sent us 4 replacements. We compared the 4 to the original to find the same degree pork chop. That is the one Byron installed.

Wayne,

Solid cast (maybe forged) iron.

IIRC the one in question cracked.

The most common failure is that the adjusting bolt strips when someone tries
to adjust the ride height without taking the load off them with the special
tool.

Check Maintenance Manual X-7525 Section 3A Front Suspension Page 3A-19 for
the pictures and procedure on how to adjust the ride height.

There's Figure 16 - Removing Torsion Bar on page 3A-14 that shows another
view.

No insert, bolt to porkchop, probably wore from being out of adjustment, one tight, one loose. The loose one probably wore from more movement. Mine was 950 lb heavy on the pass side till Mr Burton laid hands on it at Bean Station. Now I`m 100lb heavy 0n rf and 50lb on rr. My water tank is midway right side and both batteries are rf.

No rubber insert. The torsion bar has a hex end that fits in the hex hole of
the pork chop. As a piece of cast iron, it's interesting that the damage was
what it was. The torsion bar appeared to be OK.

Lots of theories. No one knows how the one on my coach got mangled on one
side. The pork chop wasn't cracked. The adjusting bolt was OK.

Here's the odd thing. With the adjusting bolt on the passenger side all the
way up (bad side) and the adjusting bolt all the way down on the driver
side, the coach appeared to be about equal in height on both sides. It was
just two inches low.

After putting in a replacement that offered the same angle, the bolts on
both sides had to be run up all the way to get the minimum ride height.

Go figure.

Of the spares we had to choose from, there were two that would have offered
a different degree of attack. The bolts would have probably needed to be run
up half way leaving more room for adjustment later on (up and down). But, it
hit the mark and I was happy. Still have dirty fingernails to prove just how
happy (and I've washed my hands several times with soap, mommy).
