These idlers can be fitted to earlier model machines, or additional idlers if desired. To fit an idler to an undrilled boom, mark two holes in the boom, opposite one another, and 45mm below the top face of the RHS section of the boom. These must be tapped to a 16" UNC thread.



To adjust the Idler assembly, assemble the idler assembly, leaving the clamp bolts on the levelling rod a little loose. Supporting the Levelling Rod so that is parallel to the boom, move the idler clamp along the stay bar into the position where the included angle formed by the levelling rod levelling rod pin-idler mount (Angle ‘Y’), and the levelling rod levelling rod pin boom - master pin (Angle ‘X’) are the same. Tighten the clamp bolts on the Levelling Rod to 15 ft/lbs.
