The life expectancy of a person with hydrocephalus depends on many factors. If the hydrocephalus affects an area that can put in danger the life of the patient, an appropriate treatment or surgery can save the patient's life and improve their prospects of life, although in some cases the surgery is contraindicated due to the risks that can entail.

BEARING FAILURE: CAUSES AND CURES - Schaeffler Group

Severe brinell marks can cause premature fatigue failure. Any static overload or severe impact can cause brinelling. Examples include: using hammers to remove or install bearings, dropping or striking assembled equipment, and a bearing onto a shaft by applying force to the outer ring. Install bearings by applying force only to the ring being press-

improved belt life. Tension-- Improperly tensioned drives will more likely generate noise. Belt tension should not be too high or too low. Too low a tension can also lead to shortened belt life or ratcheting, while too high a tension will add undue stress to bearings, shafts and other related components.

How to Read Fan Belt Numbers - It Still Runs

An "A" belt is roughly equivalent to a "4L" belt, and they can be interchanged. The outside of a 4L fan belt is roughly two inches longer than the inside. This means a 4L420 fan belt is the same as an A40 fan belt. The outside of 3L fan belt is one and a half inches longer than the inside. Some belts may also have the letter "X" included.
