be assembled immediately. Excess silicone sealant should be wiped off after assembling the mating parts.
f.
Seal Rings. Coat seal rings with oil and carefully install into their bores. If seal rings must be installed over
threaded parts, temporarily wrap the threads with tape to protect the seal ring.

related housing or container. This will provide lubrication during the first run-in until lubricant from system can reach the
bearings.
