ASSEMBLY

CAUTION

Do not weld aluminum castings. If replacement of a bearing cup or cone is required, its

associated cup or cone must also be replaced. The gearcase mechanical housing includes the

housing and cover. They are machined as a unit and must be replaced as an assembly.

If bearing cup (1) was removed during disassembly, install new bearing cup in housing (2). Heat bearing bore to

250-300 F (121-158 C), and freeze bearing cup. Position bearing cup to its associated bearing bore. Using bearing cup

replacer and soft plastic hammer, tap cup in place.

NOTE

If roller bearing cones were removed during disassembly, install new ones. New cones may be

heated in oil to 250 F (121 C) to aid installation.

Place gearcase housing (2) flat on smooth surface with cover side up.

If removed, install bearing cone (3) and bearing cone (4) on input gear (5). Install gear in housing (2).

Install secondary pump-drive gear (6) in housing (2) with smaller diameter hub toward housing.

If removed, install bearing cone (7) and bearing cone (8) on first intermediate gear (9). Install gear in housing (2)

meshing teeth with input gear (5).
