MODELS: Evinrude/Johnson V6

No. 2004-09(S)

SUBJECT: Gearcase Alignment Gauge Kit (V6), P/N 5006349

A new service tool has been developed for servicing Evinrude and Johnson outboards. Use Gearcase Alignment Gauge Kit, P/N 5006349 to check the condition of all late model V6 gearcase housings prior to reassembly.

Check the alignment of the gearcase housing on gearcase assemblies that have experienced impact damage and/or internal bearing and gear failure.

Distorted gearcase housings affect driveshaft to propshaft alignment and gear alignment. Failure to prop­erly identify distorted gearcase housings can result in replacement gear failure. This type of failure is not covered by warranty.

This gauge kit assembles to the forward bearing housing of a standard rotation gearcase and driver han­dle, P/N 311880 (existing tool). Assemble as indicated to check all V6 gearcase housings (1979 and new­er 4 hole water inlet, "0" and "L" types; and "M" and "XP" types). Refer to P&A Bulletin No. 2002-02 to properly identify gearcase types.
