Arbor Disassembly
Refer to Figure 10 for the following procedure.
1. Remove the blade from the arbor to be serviced, and
remove the arbor assembly from the mower deck
(see previous procedures).
2. Remove the nut (A), washers (B), and pulley (C).
3. Remove the spacer (D).
NOTE: If the spacer is seized onto the arbor shaft, soak
with rust penetrant to separate. If the parts must be
forced apart, thread the hex nut back onto the arbor shaft
to protect the threads and tap the end of the arbor shaft
with a rubber mallet.

4. Using a flat blade screwdriver, pry the arbor cover (E)
off. Remove and discard the gasket (J).
5. Separate the arbor shaft (O), bearings (F & I), lower
housing (K), and washer (N)
Replace parts as required.
NOTE: 38” mower decks use two identical bearings. 44”
decks use two different bearings and therefore require a
sleeve spacer (G) be used with the upper bearing (F).
38” decks do not use the sleeve spacer (G).
