- Auto-tensioner
The auto-tensioner uses a torsion spring to regulate the timing belt tension. The main components are the torsion sp.ing,
. male screw and a temale rod. The assembly is filled with oil and sealed. The spring turns the male screw. which pushes
lhe lemale rod out against the belt. The design is such that the rod cannot be pushed back into the housing by belt ten-
s'on. To pull the female rod back into the assembly. the male screw must be turned with a screwdriver.
