Spin them (one at a time) all the way around a couple of times with a 17 mm socket and a ratchet on the cam gear bolts. Beware, they will get easier/harder to turn, and on the backside of the lobe, they'll have some energy stored up, and will try and jump away from you.
An illustration of a Douglas-fir tree. The Douglas-fir was designated as the official state tree by the legislature in 1939. Oregon was the eighth state to name a state tree. It is named for David Douglas, a botanist who described the tree on his first trip to the Pacific Northwest in 1825.
Despite its name, the Oregon state flower is unrelated to the grapes you find in your supermarket produce section. This low-growing, evergreen plant derives its name from its bluish-purple berries, which grow in grape-like clusters in the fall and are a favorite for birds.
