Subject: Pics of Never-before-seen Tamper
A customer brought me a tamper he made out of a 2" hitchball. I'd never
seen this done before. Along with the pics are some I've taken today of
an overhaul I'm doing on a LM Linea to put in the veggie van. I'm having
a bit of a hassle trying to pull the element out of the steam boiler.
Even with a 3/4" drive and extension it doesn't want to budge. And some
shots of the exterior of the van. The vacuum cannister filter was set on
fire whilst trying to clean up hot embers too soon after the roaster
fire.

heat the mounting boss with a torch. you don't have to get it red,
just get it really hot. then, when it cools down a wee bit, put the
socket on and remove the element.

*probably* the threads are scaled up, and the expansion/contraction
will break the rock up. liquid wrench, mousemilk, et al, are largely
useless as the problem is rock, not rust.

this is what can happen if one uses a cheeter bar:

When I was installing auto batteries at Monkey Wards during my college
years we very often came upon rusted and corroded hold-downs where the
nut often looked like part of the long, threaded, J-hook bolt thingy.
because the parts department was not well stocked, and it was a hassle
to ring up another invoice for a new part, after cleaning it up on a
power wire wheel, we would just go into the bathroom and run the thing
under really hot water (they had the water heater set to boiling -10 I
think). Then we would tap it on the big, porcelain coated, cast iron
sink. We always got them apart this way. The heat along with the
vibrations of the tapping, as Flasherly was stating, works wonders.

I've a 6' piece of pipe I put over a 3/4" drive. I exploded out the
inside of a black impact socket on a pitman puller with the pipe over
the ratchet's handle. A rather large nut around an inch width that had
been in use since ancient times. 3/4" I have is actually a set of two,
a ratchet like you have shown and a swivel-head 3/4" breaker. I was
trying to keep to the breaker with the pipe extension and only ratchet
on semi-loose threads. Had the part out and tightened on a bench where
a 100lb. vise is mounted. What did it take after I got back from the
parts store replacing the exploded impact socket with a higher grader,
thicker impact socket of the same size? . . .just a tiny little tack
hammer. That and a can BP Catalyst (seems to have a better reputation
than Liquid Wrench). With the tack hammer swing it to hit the nut
flush with a sharp crack. Not so many - as the vibration is intended
to send the impacts shock closest through the threads going into the
boiler. May need the BP Catalyst and repeat the proceedure as needed
working back and forth on a few threads at a time as it breaks out. I
was working with a steering box near to the size of that aluminum
truck's undercarriage - my old Chevy van some woman subsequently took
out in a headon. The pipe I was using along the ratchet handle, coming
out of the vise would stretched nearly up to 7' up off the floor -
maybe getting 5 or 600 lb torque on the Chinese black impact socket
that exploded. Didn't even need the pipe extension after cracking the
piece a couple of good ones with a tack (2 or 4oz finishing) hammer. A
hardened steel 6" flatend out of chisel set to get up there and deliver
the same effect as the tack hammer is in too tight working quarters.
Impact ratchet may be nice if you've airtools.
