5.
Turn the kettle upside down and remove the bolts that hold the dump
handle and retainer and lift the retainer off the kettle.
6.
When removing nuts and spacers from the threaded studs on the bottom of
the pan, do not wipe off the silver lubricant. Without this lubricant
(NEVER SEEZ) the nuts may freeze on the studs and cause the studs to
break when the nuts are turned in an attempt to remove them.

Kettle Installation
1.
When re-assembling the kettle, be sure all nuts and bolts are tight. Check
to make sure that all electrical connections are secure. A loose connection
can heat up and burn off the wires.
2.
Set
the kettle back in place and replace
the two bolts in the pan legs.
3.
Locate the kettle so that the clutch dog lines up with the motor drive head,
and tighten the two front bolts that hold the pan leg plate, then tip the
kettle and tighten the other two bolts.
4.
Connect the three power leads, observing the color of the wires. Again,
correct color code is left to right, BLACK, RED, WHITE. (For 400V units
BLUE, BROWN, WHITE on front terminal left to right, Black on back
terminal.)
5.
Replace the terminal box cover.
6.
Turn on the agitator motor and dump the kettle. If the drive shaft does not
engage and dis-engages freely, readjust the kettle.
E.
Kettle Spring Adjustment
The purpose of the kettle counter balance springs is to reduce the force required
to dump the kettle. The spring collars are held in place by set screws that fit into
holes drilled on the bottom of the cross shaft. The spring collars have five holes
that the spring fits into. By turning the collar around, there are five different
adjustment positions for spring tension adjustment.
When correctly adjusted the springs will neutralize the weight of the kettle. To
set the springs raise the kettle to a point where it is balanced. The long leg of the
1902 spring should be just beginning to touch the bar on the bottom edge of the
hinge casting and the 1903 spring will begin to move away from the bar. If the
springs press against the bar too soon the kettle will seem lighter but the springs
are fighting each other. This condition will shorten the life of the springs.
An important part of this assembly are the two washers between the 1902 spring
and the plate welded to the cross shaft. They act as both bearings and spacers;
without them the spring may have a short life.
