Maintenance Instructions
9. Position the gear drive assembly on the deck
and install the 3/8-16 bolts mounting the entire
assembly. Leave the mount bolts finger-tight.
10. Torque all the connector tube bolts to 80 in-lb
(9 N m); then tighten the deck mount bolts.
NOTE: This fastener tightening sequence aligns
the gearbox assembly with the deck housing and
eliminates the possibility of mounting the unitized
assembly in a bind.
11. Fill gearbox assembly with oil. Refer to Mower
Deck Gearbox Lubrication in this section for in-
structions.
12. Reassemble remaining items onto deck to com-
plete installation. After installing the blades,
check that the blade timing is correct by moving
the blades through one (1) complete revolu-
tion. Make sure blade tips pass clear of each
other.
