washer-extractors with a rubber spring suspension also have shock absorbers. The shock
absorbers have a different type of connection than those for automobiles. It is not necessary to re-
place the shock absorbers at specified intervals. It is only necessary to replace them if there is an
indication that they are damaged or very worn.
Examine the shock absorbers at the intervals given in the maintenance summary. It is necessary
to replace a shock absorber if you see oil come out from the mechanism (see the figure that fol-
lows). This shows that seals are worn. It is also necessary to replace the shock absorber if the rub-
ber in a connector is very worn or missing.
Bad shock absorbers will let the shell move too much when the machine operates. If severe move-
ment occurs and you are not sure of the cause, you can do a test of the shock absorbers as
follows:
1. Remove the shock absorber from the machine.
2. With your body weight, compress the length of the shock absorber against a hard surface. A
serviceable shock absorber compress slowly. It will also expand slowly to its initial length
when you release it. If it compresses or expands quickly, the shock absorber is bad.
