The suspension system on Milnor
®
Hydro-cushion™ machines is adjusted and thoroughly tested
at the factory. It should not require subsequent adjustment unless the machine is distorted during
shipment or installation or unless some component of the system, such as a Hydro-cushion™ cyl-
inder is replaced.
There are two primary objectives when adjusting the suspension system on any Hydro-cushion™
machine model:
1. To position the shell in the proper location within the frame (hanging dimensions) to maxi-
mize freedom of movement of the shell and to insure proper draining, and
2. To adjust the length of up and down travel at each of the push-down locations (push down
travel) so that the shell will not be distorted (racked) when pushed down.
All Milnor ® Hydro-cushion™ machines contain the following suspension system components:
1. Hydro-cushion™ cylinder—which suspend the shell and cylinder within the frame and pro-
vide vibration damping during extraction.
2. Pneumatic push down devices (air bags)—which when inflated, force the shell downward
where it is held against rigid pads during loading, unloading, washing, and draining.
3. Metal or rubber pads—some rigidly fixed to the shell and some rigidly fixed to the frame,
which come in contact when the shell is pushed down.
The actual configuration of these components varies from model to model.
How Shell Adjustments are Made

Regardless of machine model, repositioning of the shell is always accomplished by adjusting the
nuts at the top of the upper Hydro-cushion™ shafts. To move the shell up or down at the location
of any Hydro-cushion™, see
Figure 37: Hydro-cushion™ Upper Shaft and Adjusting Nuts, page
97 and proceed as follows:
CAUTION:
These procedures should be accomplished with power to the machine
locked off.
1. Straighten the tongues on the keyed lock washer using pliers, screw driver, etc.
2. Loosen the lock nut (upper hex nut) and move it all the way up to the top of the shaft, but do
not remove it.
