Install the outer seal O-ring (Figure 53, item 54) into the groove in the outer seal (item

Mechanical seal guidelines/notes
1.
The lapped faces of mechanical seal components are extremely flat and smooth. Use
great care when handling these components to prevent damage and reduced seal
performance.
2.
Although it is impossible to prevent touching the seal faces during assembly, use clean
hands and try to minimize contact with the lapped faces.
3.
Keep the work area clean to prevent contamination of the seal faces.
4.
O-ring lubrication is important to ease assembly of the components, prevent O-ring
damage, and provide proper seal function. The lubricant chosen must be non-toxic
and compatible with the O-ring material.
5.
Clean water can be used as an assembly lubricant for the O-rings if no other lubricant
is available.
6.
Seal seats should sit squarely against the shaft shoulder.
7.
The inner and outer seals should not bind in their respective bores. When pushed by
hand, the wave springs should return the seals to their starting position.
