POWER-FRAME ASSEMBLY1) Clean and visually inspect all parts prior toreassembly. Particularly note condition ofshaft surfaces and housing bores where oilseals contact.2) Evenly heat bearings up to 167°F (75°C)above room temperature, approximately 239°F(115°C). Do not exceed 257°F (125°C) asdamage to the bearings may occur.WARNING: SINCE THE SHAFT IS TYPICALLYMADE OF STAINLESS STEEL, PRESSINGTHE BEARINGS ON THE SHAFT MAYRESULT IN DAMAGE TO THE SHAFT.3) Note orientation of bearings before installingon shaft:Outboard Bearing (coupling end) – If bearingcontains ball filling slots, the slots should befacing the coupling (key-way) end of shaft. Ifthe bearing has a single shield, the shieldfaces toward the coupling end of the shaft. Ifthe pump is provided with re-greasable bearings,the bearing grease shield should facethe impeller (threaded) end of shaft.Inboard Bearing (impeller end) – If bearingcontains ball filling slots, the slots should befacing the coupling (key-way) end of shaft. Ifthe bearing has a single shield, the shieldfaces toward the threaded end of the shaft. Ifthe pump is provided with re-greasable bearings,the bearing grease shield should facethe coupling (key-way) end of shaft.4) Install the outboard bearing (Item 18) on theshaft (Item 6) by sliding it over the key-wayend of the shaft until it is seated squarelyagainst the shaft shoulder.5) Place the retaining ring (Item 18A) over theshaft before installing the inboard bearing, asthis is impossible to install later.6) Install the inboard bearing (Item 16) on theshaft (Item 6) by sliding it over the threadedend of the shaft until it is seated squarelyagainst the shaft shoulder.7) Install the lock-washer (Item 69) and lock-nut(Item 22) against the outboard bearing andthen tighten the lock-nut with a bearing locknutwrench or by tapping the groove in thelock-nut with a hammer and drift. The lock-nutcan then be secured by bending the tang onthe lock-washer into the groove on the locknut.Be careful not to mar the oil seal surfacesof the shaft which are in close proximity to thebearings and lock-nut.8) Install the o-ring seal (Item 33B) on thebearing housing.9) If the bearing frame is provided with labyrinthtype oil seals, lubricate the seal o-rings andpress fit the labyrinth seals (Items 47 & 49) intothe bearing housing and bearing frame bores.10) Install the shaft and bearing assembly into thebearing housing (Item 33), by first lubricatingthe bore with some oil and then sliding in theshaft assembly. Lightly tap the bearing housingwith a soft-headed mallet until the outboardbearing clears the retaining ring groove. Usingsnap-ring pliers install the retaining ring (Item18A) with the opening in the ring lining up withthe oil return slot in the bearing housing.11) If the bearing frame is provided with lip type oilseals, install the outboard oil seal (Item 49) intothe bearing housing. Lubricate the ID of the sealand place sealant around the OD of the seal.Carefully place the oil-seal over the shaft watchingout for sharp edges such as on key-ways andplace up against the bore. Seat the oil-seal inplace with a soft-faced tool applying force evenlyaround the outer edge to avoid cocking the seal.Wipe off any excess sealant.12) The shaft assembly is now ready for installation.Ensure that the power-frame is free of contaminantsand then lubricate the bores in the powerframewith oil to ease installation. Line up theshaft assembly so the oil-drain slot in the bearinghousing is facing down and slide the shaft assemblyinto the power-frame as far as it will go byhand. Check to be sure the assembly is going instraight. Lightly tap the key-way end of the shaftto assure the shaft is in its forward most position.Be careful not to pinch the bearing housing o-ringseal (Item 33B) on the power-frame, or damagethe o-ring in the labyrinth oil seal.13) Install the adjusting screws (Item 33A). Ifscrews are of different length, the longerscrews thread into the power-frame.14) Install the inboard lip type oil seal, if required(Item 47) into the power-frame. First ensurethat the bore and shaft diameter are cleanand free of scratches or grooves. Lubricate12
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 <strong>Fybroc</strong> 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.
