Cutter Shaft Removal

Support and block cutter shaft at both ends of bearings and support the shaft which is being removed under the drive side. Remove outer bearing as outlined in the Maintenance Section, page 5-7. Remove knockout which is fastend by 2-1/2" bolts. Remove free end skid.

Shaft may drop or slide toward center and cause injury. Add sufficient support under both cuttershafts.

Use floor jack to lower the non-drive end of the cutter shaft. Remove bearing from drive end,page 5-7. Use floor jack to support drive end inside deck. Move toward free end to losen. It is not necessary to remove shaft if only bearing is being serviced.

The center bearing is locked to the cutter shaft at two points (3). These set screws align with dimpled holes in the shaft and are “locktighted” in place. Remove both set screws. Both are secured with thread locking compound and may require considerable pressure to loosen. Clean shaft and remove any burrs before attempting to slide bearing outward on shaft.

To install the bearing, slide bearing over shaft and align set screws with dimples in shaft. Tighten both set screws securely to shaft. Lock with both set of set screws, apply a thread locking compound. Installation of shaft assembly is reverse of removal procedure.

TOP DRIVE ASSEMBLY SERVICING

Note: On 20' models, pulley shaft is stepped down at bearing journals and cannot be slid through without unbolting bearing assembly.

To replace inner bearing or top drive u-joints, first remove belt , pivot bolts and inboard mount weldment before sliding entire assembly toward pulley side. It may be necessary to remove set screws which lock top shaft to pulley shaft. There are no locking screws located on spline side by gear box.
