MAINTENANCE
spindle removal/ replacement.
Complete the Disc removal procedure described above.
• Remove the pulley from the outside end of the spindle first loosening the two boss
screws with a 3/8” open ended spanner. Note: A puller may be needed to remove
the pulley from the shaft, if it wont come off with gentle tapping/ levering. BE VERY
CAREFUL NOT TO BEND THE PULLEY FLANGES.
• Using a soft hammer, tap the spindle shaft on the ‘pulley’ end and it should move out
of the bearings.
• Inspect the bearings for signs of overheating, loss of grease, looseness or ‘lumpy’
operation when turned. Also inspect the fit of the bearings in the housings. They must
be a very firm sliding fit. Replace the bearings if they are visibly worn.
NOTE When re-assembling, ensure the shoulder on the spindle shaft is hard against the
inside bearing. Next, the pulley boss must be positioned fully in against the outside
bearing, with the boss screws on the outside of the pulley. Ensure the boss screws are
opposite the flats machined on the spindle end, and apply a thread locking compound
to the boss screws before tightening.
Chipper re-assembly
Basically, re-assembly is the reverse of the procedures listed above. However, after
assembly, check that the chipper blades do not contact the anvil at the base of the hopper
by rotating the rotor by hand.
