2 Small Chamfer Faces Up
Warning

Do not force the seal installer down over the seals as this will roll and damage the seals. The large chamfer is designed to fit over the over stretched seal. Use a hand to help shrink the seal if the seal installer is difficult to install over the seal rings.


Procedure

Install DT 46620-1 which is part of DT-46620 seal installer with the large chamfer end down over the fluid seal rings and leave DT 46620-1 which is part of DT-46620 seal installer on the seals for at least 60 seconds.
3 Large Chamfer Faces Up

Procedure

1. Install DT 46620-1 which is part of DT-46620 seal installer with the small chamfer end facing down for at least 60 seconds. This will properly size the bottom seal ring.

2. Leaving DT 46620-1 which is part of DT-46620 seal installer on the fluid seal rings for an extended period of time could cause a fluid leak on the initial clutch piston circuit until the seal rings warm up and expand to the proper dimension.
