Cutting Units: Service and Repairs

The spring is under heavy load and can cause personal injury.
Be careful when applying the tension from the torsion spring of the
idler arm.

of the idler arm torsion spring (5). Apply enough load against the torsion
spring to release it from the spring stop or the idler arm and carefully lower
the idler assembly all the way onto the idler pivot (14). Slowly release the
torsion spring against the spring stop and idler arm.
4. Secure the idler assembly to idler pivot with retaining ring (2).
5. Use a ⅜" or ½" drive ratchet or breaker bar to relieve idler pulley tension and
install drive belt. Ensure that the idler pulley applies tension against the
back side of the belt.
