The driver can be made from tubular stock as shown in Figure 6 on previous page. The tool applies a uniform pressure
to the recessed area of the seal, rather than to the lip of the seal. The inside diameter of the tool will not interfere
with the garter spring located around the lip of the seal.

Periodic inspection of the fluid condition and tube or piping connections can save time consuming break downs and
unnecessary parts replacement. The following should be checked regularly.
1. All hydraulic connections must be kept tight. A loose connection in a pressure line will permit the fluid to leak
out. If the fluid level becomes so low as to uncover the inlet pipe opening in the reservoir, extensive damage
to the pump can result. In suction or return lines, loose connections permit air to be drawn into the system,
resulting in noisy and/or erratic operation.
2. Clean fluid is the best insurance for long service life. Therefore, the reservoir should be checked periodically
for dirt or other contaminates. If the fluid becomes contaminated, the system should be thoroughly drained
and the reservoir cleaned before new fluid is added.
3. Filter elements also should be checked and replaced periodically. A clogged filter element results in a higher
pressure drop. This can force particles through the filter which would ordinarily be trapped, or can cause the
by-pass to open, resulting in a partial or complete loss of filtration.
4. Air bubbles in the reservoir can ruin the pump and other components. If bubbles are seen, locate the source
of the air and seal the leak. See Table 1.
5. A pump which is running excessively hot or noisy is a potential failure. Should a pump become noisy or
overheated, the machine should be shut down immediately and the cause of improper operation corrected.

When hydraulic fluid is added to replenish the system, it should always be poured through a fine wire screen (200
mesh or finer) or preferably pumped through a 10 micron (absolute) filter.
It is important that the fluid be clean and free of any substance which could cause improper operation or wear of the
pump or other hydraulic units. Therefore, the use of cloth to strain the fluid should be avoided to prevent lint from getting
into the system.

Internal lubrication is provided by the fluid in the system. Lubrication of the shaft coupling should be as specified
by their manufacturers.
