SEAL-O-RING 3407565 - Caterpillar

Orient the impeller end of shaft (21) to the upward position. Lubricate the stationary segment of the ceramic seal with a solution of water and five percent soap. Place the side of the segment with the bevel in the downward position. Use hand pressure in order to install the segment into drive housing (15). After the seal is installed, wipe the surface dry.

Determine the thickness of the shims for the impeller. The shims will be used in order to obtain a clearance of 0.18 to 0.23 mm (0.007 to 0.009 inch) on each side of the impeller.Place a straight edge on the face of the port plate (11) across the opening for shaft (21). Use a feeler gauge to measure Dimension (X) between the shoulder of the shaft and the face of the port plate.The correct thickness of the shims is Dimension (X) plus the specification of the clearance. Table 2 is an example of the calculation.
Table 2
Example of the Calculation for Determining the Thickness of the Shims
Dimension (X) Clearance Specification Thickness of the Shims
0.56 mm
(0.022 inch) + 0.20 mm
(0.008 inch) = 0.76 mm
(0.03 inch) In the example, the proper thickness for the shims is 0.76 mm (0.030 inch).

Install spacer (12) (not shown). Install shims (8). Install key (8A). Note: The spacer and the shims will protrude slightly above the port plate. This is normal. When the impeller is installed, the spring in the ceramic seal will be compressed and the spacer and the shims will be pushed down.Note: The impeller has threaded holes for the puller. Install the impeller with the holes toward the outside.
