Catalog EPS 5350/USAEngineeringProTech Bearing Isolators88InstallationStandard Design InstallationThe ProTech seal is unitized; any attempt todissemble the seal will damage it. After makingany adjustments to the equipment, confirm that theseal is still properly installed.Prior to Installation1. Warning! Disconnect all system power, andfollow all standard safety procedures.2. Remove all sharp edges from the following:a. Lead-in chamfersb. Keywayc. Splinesd. Snap ring grooves3. Clean all foreign debris from bore and shaftareas.Installation1. Lubricate bore and shaft O-rings with systemcompatiblelubricant.2. Position the sealover the shaft byhand. Seal positionis correct if thestator O-ring istowards the sealhousing as shown.3. Slide seal down thePosition the Sealshaft, stopping justbefore the seal housing of the equipment. Usehand pressure only.4. Rotate the seal sothat the drain port iscentered at the sixo’clock position.Press seal into boreusing hand pressureonly. If necessary,gently tap seal intobore using a softfacedtool.Installing the SealDO NOT USE A METALLIC HAMMER ORPUNCH as this may damage the seal.Split Seal InstallationPrior to Installation1. Warning! Disconnect all system power andfollow all standard safety procedures.2. Remove sharp edges on the shaft and borewhere the seal will be installed. Make sure thereare proper lead-in edges.3. Clean all foreign debris from the bore and shaftarea.Installation1. Pre-lubricate the O-rings with a systemcompatiblelubricant.2. Position the shorter O-ring on the shaft andplace the two halves of the rotor, with the flangesides facing away from the bore, over the O-ringso the O-ring fits into the groove (see Fig. 8-2).(It might help to first paste the O-ring to the shaftwith a light coat of grease.) Then place thescrews in the rotor halves and screw the twohalves together loosely. Do not tighten the screws.Bearing SideStatorOil DrainDrain Port (Outboard)Figure 8-2.
