ASSEMBLY
1. Attach outboard bearing plate to cutterhousing.
FORWARD ROTATION (Bearing plate mounts on left side of cutterhousing.)
a. Secure with 3/8 NC x 7/8 HHCS and nut at front mounting hole. Torque to 35 ft-lbs. (Typ.)
b. Secure with 3/8 NC x 2-1/4 HHCS, nut, lock washer, and second nut at rear mounting hole. The HHCS is
used as an anchor for the idler arm spring.
REVERSE ROTATION (Bearing plate mounts on right side of cutterhousing)
a. Secure with 3/8 NC x 2-1/4 HHCS, nut and second nut at front mounting hole. The HHCS is used as an
anchor for the idler arm spring.
b. Secure with 3/8 NC x 7/8 HHCS and nut at rear mounting hole.
2. 2. Install gearbox & extension shaft assembly and PTO shield mounting bracket
a. Remove existing nuts and lock washer from bearing housing.
NOTE: On forward rotation units, remove only the lower two fasteners.
b. Slide bearing housing HHCS into proper holes in outboard bearing plate.
c. Attach gearbox and mounting bracket to gearbox mounting frame. Secure with 5/8 NC x 1-1/4 HHCS
(upper gearbox feet), and 5/8 NC x 1-1/2 HHCS (lower gearbox feet) and Lockwashers. Torque to 170 ft-lbs.

If extension shaft does not line-up with Gearbox, it may be necessary to shim gearbox
mounting lugs. To accomplish this, insert one gearbox retaining bolt (Item 1), ASM-FL-
0050 thru the mount plate and into the gearbox housing. Do not tighten this bolt (it should
have at least 1/4" free threads to move in and out). Assemble the gearbox, shaft, shaft
extension tube and the bearing to the bearing retainer plate mounted on the side sheet.
Tighten all fasteners except the one bolt in the gearbox mounting plate. Check the
distance between the gearbox mounting lugs and the mount plate. If required, insert shims
from shim kit (P/N 000552), ASM-FL-0051 between gearbox mounting lugs and mounting
plate to insure the gearbox pulls up evenly on the mounting plate.
