Fabricated Tools

Usage:

The disassembly and assembly of this marine gear can be facilitated by the use of the following fabricated tools:

FT836 Bearing Cap

FT836 BEARING CAP

After the top shaft assembly has been replaced in the housing, the FT836 Bearing Cap should be used to properly seat 6L5438 Bearing Assembly in its bore. When the 6L5438 Bearing is properly seated, the two remaining bearings will also be seated correctly.

FT840 Retaining Brackets

FT840 RETAINING BRACKET

When installing the top shaft and clutch assembly, two FT840 Retaining Brackets should be used to prevent the top shaft from sliding out of the clutch pack. The brackets can also be used while disassembling the clutch.

PULLING LOWER SHAFT

The FT850 Locking Bracket provides a secure method of pulling the lower shaft loose from the 4L1257 Ahead Driven Gear. This bracket provides an adjustable spacer between the gear and the compartment wall. Thus, the bracket distributes the load over a wider area and prevents damage to the compartment wall when the puller is utilized.
