the ID of the seal and place sealant aroundthe OD of the seal. Carefully place the oil-sealover the shaft watching out for sharp edges suchas on impeller threads and place up against thebore. Then seat the oil-seal in place with a softfacedtool applying force evenly around the outeredge to avoid cocking the seal. Wipe off anyexcess sealant.15) Install the deflector (Item 40), if bearing frameis provided with lip type oil seals, by sliding onthe shaft.16) Install sight-glass, breather and plugs (Items19A, 19B, 19C, 19G and 19H) in their respectivelocations.17) If separate, install the frame-leg (Item 19E) andsecure with frame-leg screws (Item 19F), torqueto 25 ft-lbs.18) If separate, install the bearing frame adapter(Item 71). Ensure that the adapter is seatedsquarely on the power-frame before tighteningadapter screws, this may require some sandingof the paint on the pilot diameters. Secure withadapter screws (Item 71A), torque to 25 ft-lbs.19) Install the casing jack-screws (Item 19D), ensurethat the screws do not extend past the cast ironcover adapter, as damage could result to the pump.CAUTION: Prior to starting the pump, re-lubricatethe bearing frame.PUMP END ASSEMBLY1) Inspect casing, cover and impeller for anydamage and make sure all sealing surfaces arefree of dirt and scratches. If pump is equippedwith an internal seal flush, make sure cover flushhole is clear.2) Use the adjusting screws (Item 33A) to adjustthe bearing housing (Item 33) to its forward mostposition and then lightly coat the shaft threadswith an anti-seize compound.3) The Fybroc pump, as standard, is equipped witha single outside seal with stationary seal faceand rotating compression unit, or a double insideseal with stationary seal faces and rotatingdouble seal compression unit. The followinginstallation instructions are based on these sealtypes. When other types of seals are used,please refer to the manufacturer’s installationdata. Determine the type of seal being used andrefer to the following sections.13SINGLE OUTSIDE SEAL INSTALLATIONJOHN CRANE TYPE 8B21) Remove the mechanical seal from its packaging,inspect for any damage, and keep seal faces cleanand free from contaminants during installation.DO NOT GREASE OR LUBRICATE SEAL FACES.2) Install the inboard stationary seal gasket and thestationary seal insert into their bores on thepump cover. Then place the outboard stationarygasket over the stationary insert. Next place theseal gland over the stationary insert and gaskets,making sure that all the gaskets have beeninstalled properly before securing the gland bolts.Be sure that the gland pilot is properly engaged,and draw up the gland bolts evenly, cross staggeringadjustment of the bolts. Proper gland boltadjustment is especially important where clampstyle inserts are used. The gland bolts should betorqued to a maximum of 10 Ft/Lbs.3) Lightly coat the impeller sleeve with a suitablelubricant. Carefully slide impeller sleeve throughthe cover, being careful not to chip the stationarysealing face.3A) For separate shaft sleeve installation, positionthe cover over the impeller and insert the sleevethrough the mechanical seal stationary insertuntil the hooked end of the sleeve rests on theimpeller hub.4) Lubricate the rotary unit o-ring with a suitablelubricant. Then engage the rotary assembly overthe impeller sleeve. Use a slight twisting motionas the rotary unit is slid down the impeller sleeveuntil it touches the stationary sealing face. Donot tighten set screws or remove setting clips.5) Mount the impeller, cover and seal assembly ontothe power-frame, making sure the impellerthreads are firmly bottomed on the shaft threads.5A) For separate shaft sleeve installation, slide thesleeve and seal assembly over the shaft until thehooked end of the sleeve bottoms on the shaftshoulder. Install and clamp cover in position.Insert impeller o-ring (Item 2B) in the groove onthe impeller hub and thread impeller onto shaftinsuring impeller hub, sleeve hook and shaftshoulder are firmly bottomed.6) At this stage check to be sure the impellerthreads are properly seated on the shaft threads.There should be clearance between the coverface and the back of the impeller. If there is no
