Location of Shaft Seals on Piston Pump (Steering)

Illustration 1 shows the double shaft seal configuration that is used on 950G, 962G, 950G Series II, 962G Series II, IT62G, IT62G Series II, 980G, 980G Series II, and 980H.

Not shown is the single shaft seal configuration that is used on 966G, 966G Series II, IT62G, IT62G Series II, 972G, and 972G Series II.

The improved 8T-4750 Lip Seal has been available from a new source since January 1, 2005.




Illustration 2g01168003

The faces of the two versions of 8T-4750 Lip Seal are shown.

(1) New 8T-4750 Lip Seal with no writing on the face

(2) Old 8T-4750 Lip Seal with writing on the face

The new version of 8T-4750 Lip Seal (1) is lighter brown in color than the old version. Also, the face of the new seal is smooth and the face has no writing. The new seal has writing on the back of the seal. The old seal (2) has writing of the face of the seal. The new seal can be distinguished from the old seal by these differences.
