SECTION 1-D TECHNICALREDI-SLEEVESGENERAL INFORMATIONREDI-SLEEVES INSTALLATION AND REMOVALRedi-Sleeves InstallationEach Redi-Sleeve comes with its own installation tool and removable installation flange. The installation tool reducesthe possibility of sleeve distortion and provides for sleeve installation without removal of the shaft from the servicedequipment.1) Minimum shaft surface preparation is required. Clean the old seal surface thoroughly and file down burrs andrough areas.2) Determine sleeve position necessary to cover the seal wear tracks. Measure to a convenient point or markdirectly on the shaft.3) Redi-Sleeves may be installed to any depth. The column labelled “Installation Depth” in the Redi-Sleeve SizeListing indicates the maximum distance from the end of the shaft the sleeve can be installed using the suppliedinstallation tool. Check whether the supplied tool will reach this position. If not, a tool can be fabricated using tubingor pipe to make deeper installations. If this is required, make sure the ends are cut square and are deburred.4) Fill any deep scores or gouges on the shaft with a thread repair compound. Make sure to install the sleeve priorto the filler hardening.5) Drop the Redi-Sleeve into the installation tool so that only the flange projects. Note that the flanged end of thesleeve goes on the shaft first.6) Gently pound the center of the installation tool with a wood block or large soft face mallet until the sleevereaches the previously measured point on the shaft. The wood block or large soft face mallet reduces the possibilityof distorting the installation tool.7) If clearance is required after installation, the Redi-Sleeve flange can be removed. Prior to installation, use sidecuttersto cut through the flange to the pre-cut line. After the sleeve is installed, pry flange away from the sealsurface. The flange will peel away along the pre-cut line.Redi-Sleeve RemovalSuggested methods of sleeve removal:1) Application of heat will cause the sleeve to expand and permit removal.2) Wire cutters may be used to “tear” the sleeve from the shaft using a twisting motion.3) With the flange removed, tapping the sleeve with a hammer may cause stretching on the sleeve and allow forremoval.XX
