Maintenance Instructions

REPLACING/REPAIRING

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.
