Assembly as extracted out of the front of the eccentric shaft.
Oil thermo bypass pellet assembly separated into it's three components
Left: Front eccentric bolt
Notice large copper crush washer and rubber o-ring at tip of bolt which needs to be inspected and replaced if needed.
Middle: Oil thermo bypass pellet itself.
Right: Retaining spring.

Left: Retracted position - when oil is cold.  This is the position it stays in when it fails.
Right: Extended position - when oil is hot.
The oil thermo bypass pellet extends to plug the bypass oil passage in the front of the eccentric shaft.  This bypasses oil flowing to the rotor bearings until oil is warmed up.
