down.
2. Install the shaft and washer assembly through the
arbor housing (K), bearings (I & F), and spacers (H &

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)
3. Fill the housing with Simplicity Multi-Purpose Lithium
Grease or equivalent.
4. Assemble the foam gasket (J), arbor housing cover
