Procedure to Salvage Shaft Seal Area
Grooves in the seal area that can be felt with a fingernail, as shown in Illustration 272, can be removed to make the part usable again.Note: Follow the metal spray manufacturer directions carefully in the application of metal spray to the shaft seal area.The salvage procedure is as follows:
Measure the shaft outside diameter at the seal area and the shoulder radius (if present) and make a note of each dimension.
Worn or damaged surfaces designated as salvable by chrome plating can also be salvaged by a metal spray process. Metal spray is an acceptable method of restoring a surface to the original size. Each step in the procedure is critical in achieving the desired coating bond and surface finish. See any of the thermal spray Reuse and Salvage Guidelines found in the "References" section at the beginning of this document for more information.
Grind the seal area to the diameter you measured in Step 1. The surface finish must be 0.40 to 0.80 µm (16 to 32 microinch). The wheel radius must be the same or greater than the shoulder radius measured in Step 1.Spline Measurement

Measurement of the shaft splines.
If the splines have a visible wear step, the shaft cannot be used again. If necessary, measure the splines. Use two pins placed in the splines 180° apart. For shafts that have an odd number of spline teeth, put the pins in splines as near to 180° apart as possible. Put rubber bands around the pins and shaft to keep the pins in place. Refer to Illustrations 273 and 274. Refer to the manufacturer for reusability specifications for the pin diameter and the use again dimension. Use an outside diameter micrometer to measure across the pins. The crown splines must be measured at the center of the spline for the correct measurement. If measurement is less than the dimension given by the manufacturer, the shaft cannot be used again.
