Reaction Internal Gear & Support

Fig. 33, Reaction internal gear & carrier bearing location:

1. Install reaction gear support to case bearing onto the case hub as shown in Fig. 33. Apply suitable grease to assembly to facilitate installation.
2. Install reaction internal gear and support onto bearing.
3. Install reaction carrier to support thrust bearing assembly onto the support. Ensure outer bearing race faces towards the support.
4. Install reaction carrier onto the thrust bearing.
5. Install lo and reverse clutch plates into case lugs as follows:

Fig. 34, Lo & reverse clutch plate chart. 1986:

a. Install steel plate and alternate with composition plate, refer to Fig. 34 for correct number of plates to be used.

To install the new lo and reverse clutch assembly components and for proper selection of the lo and reverse selective backing plate, proceed as follows:

Fig. 37, Lo & reverse clutch spacer plate selection chart. Transmissions built after February 9, 1987:

b. On a flat work surface, stack up the following lo and reverse clutch assembly components; 1 waved plate, 5 fiber plates and 4 steel plates, Fig. 37, starting with one fiber plate and then alternating with a steel plate. Then position lo and reverse clutch support assembly. Apply an evenly distributed load to the top of the lo and reverse support assembly (number 679). A light pressure of approximately 5 lbs., on the lo and reverse support assembly will provide the correct dimension for measurement. Do not apply excessive pressure. Measure height of the clutch pack from the work surface to the top of the lo and reverse clutch support (number 679). Use dimension "D" Fig. 37, to select the proper thickness of the selective spacer plate for assembly. Install the proper selective spacer plate between the wave plate and first fiber clutch plate with the identification point facing upward. The overall height for dimension "D" with the selective spacer plate included should be 1.20-1.24 inch.
