10. Make sure both bores are correctly aligned and
concentric. Move slowly and carefully.
Figure 3.19.
CAUTION
Do not force rings abruptly against each other. A
strong impact may break the oil seal
components. When seal is installed properly,
fasten all components well.
If DUO-CONE oil seal is installed incorrectly, these
conditions can result:
• Toric ring can warp. Figure 3.20.
!
CAUTION
• Misalignment or a twisted Toric ring may cause
leakage in the DUO-CONE oil seal. If installation
was not correct, remove oil seal from bore and
repeat steps 3-6.
• A Toric ring must never slide on any ramp of oil
seal ring or bore. To prevent sliding, wait at
least two minutes for trichloroethylene to
evaporate before continuing with installation.
When in the correct position, Toric ring must
roll only on ramps.
• A small piece of lint can separate the oil seal
surfaces and cause leaks. Figure 3.17.
8. Clean oil seal surfaces with lint-free cloth or paper.
9. Apply a thin, uniform film of clean oil on oil seal
surfaces with cloth or clean finger. Do not get oil
on Toric ring. Figure 3.18.
