Small Chamfer Up

Notice: Do not force J-46620-1 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 J-46620-1 is difficult to install over the seal rings.

Tip
Install J-46620-1 which is part of J-46620 with the large chamfer end down over the fluid seal rings and leave J-46620-1 which is part of J-46620 on the seals for at least 60 seconds.

Large Chamfer Up

Tip

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