Figure 9-4 Installing V ring with adjacent protecting ring
① Auxiliary disk for assembly purposes
② Greased
③ Grease-free
1. The V ring is in the correct axial position when the end face of the bearing cap is flush
with the outer edge of the V ring. Use an appropriate auxiliary installation disk for this
purpose.
2. If a protecting ring made from sheet metal has been fitted in the bearing cap to protect
the V ring, when installing the ring, ensure that it is still has sufficient pretension and that
one of its two slots lines up with the water drain slot toward the bottom of the bearing cap
or end shield.
