FIGURE NO. 3 - TURBINE SHAFT OIL SEAL RINGS INSTALLING AND SIZING
SERVICE ACTION
Solid turbine shaft seals must be used on all 1987 THM 700-R4 transmissions produced with Auxiliary Valve Bodies. If "scarf cut" seals are used on a
1987 model with an auxiliary valve body assembly, a condition of burned forward, overrun or 3-4 clutches can occur. Both types of turbine shaft seals
can be used on a 1982 through 1986 THM 700-R4 transmission but solid seals are recommended on all models. Installation and sizing of solid turbine
shaft seals is done with Kent-Moore tools J-36418-1 and J-36418-2 (Figure No. 3). The Kent-Moore sizing tool J-36418-2 needs to be altered at the
flanged end of the tool. The instruction sheet that comes with the tool shows to use the tool with the flanged end down. The flange must be removed to
allow the tool to size the bottom seal ring. Alter the Kent-Moore sizing tool using the following procedure:
1.
Place the sizing tool in a vise (Clamp flange in vise jaws).

2.
Cut the flanged end off at the bottom of the tool as shown in Figure No. 4.
3.
File any rough edges until smooth.
