FIGURE 1 - INPUT CLUTCH HOUSING AND SHAFT ASSEMBLY:

Beginning on July 29, 1986 (Julian Date 210) all 1987 THM 440-T4 transaxles were built using a new design input housing and shaft assembly (Item 626, Figure 1). Changes to the input shaft housing diameter require the use of new seal installation tools for the input and 3rd clutch inner piston seal, J-37361 and J-37362. Previously released seal installation tools, J-34091 and J-34092, are still applicable for the 1985 and 1986 models.
