Features/Benefits

* Used to remove and install final drive bearing locknut when replacing bearings or Duo-Cone seals

* Used with standard torque wrench to obtain up to 950 N·m (700 lb ft) of torque

* Used on CS-533C, CP-533C, CS-563C, CP-563C and CS-583C Vibratory Soil Compactors

* Spanner wrench is designed to fit down inside deep housing bore (locknut is over 90 mm (3.5 inch) down inside housing)

* Designed to extend out beyond face of housing (round shank of spanner wrench extends beyond housing face and through alignment bracket)

* 126-6610 Alignment Bracket bolts directly onto housing and provides a reaction point for torque wrench (permits one-person tightening of locknut)
