6.2.4.3.2 Pump Unit. Item 204.6 of the A17.2 Manual relates to checking for excessive oil in
drip pans under the pump unit. Good maintenance will keep oil leakage to a minimum. There
will be some because of vibration, but it can be kept to a minimum. Some pump units are
designed where components are housed in the oil storage tank. (See Figure 3-5 and 3-6). One of
the reasons for this is to reduce the need for tight fittings. Leakage indicates a potential problem
and, when found, the problem should be corrected. Many times guards are removed to service
equipment and in haste are not returned to their proper place. A guard sitting off to the side is
not doing its job and could result in a serious accident. A thorough check of the pump motor and
pump bearings should be made on each inspection trip. Problems in these areas do not happen
overnight. If found early, they can greatly reduce repair costs and time. Bearing problems are
detected by sound and/or heat.
