SEALING DISC ASSEMBLY
See Parts Identification on Page 8.
1. Insert the inner pivot bushing (29) into the pivot collar of the knife plate (28).
2. Hook the pushrod (31) onto the peg of the knife plate.
3. Attach the disc sealer arm (17) to the knife plate at the pivot collar using the 1/2” x 4-1/2” bolt (23) and
lock hex nut (19).
4. Slide the spring bracket (37), spring (20) and spring bushing (38) onto the pushrod and secure with the
3/4” hex lock nut (22).
5. Before assembling the blade, bearing assembly and hubcap, remove the seal (optional) from the
exposed side of the bearing assembly if you choose to grease the bearing, otherwise the bearing is
sealed. Lubricate every 50 hours. NOTE: The washer must be installed or the blade will fall off during
use.
6. When assembling, be certain to align the grease zerk with the hole in the blade and the groove in the
hubcap to provide the grease with a channel to get to the bearing.
7. Attach the disc assembly to the disc bracket (16) and fasten with the 5/8” hex nut (15). Then bolt the
disc and bracket assembly to the sealer arm, previously attached to the Maverick Opener in step 3,
using the 1/2” x 2” carriage bolt (13). NOTE: A reference point to start with the angle of the blades is
illustrated below.
