Maintenance (Continued)372T 113A 408W408W761B408N319408M408N408A370F2412. Install the outboard bearings (112A) on the shaft (122).The regreasable bearing has a single shield. Make sure that the bearing is installed with the shield awayfrom the impeller.The duplex bearings are mounted back-to-back. Make sure that the orientation of the bearings arecorrect.a) Inspect the shaft (122) to ensure that it is clean, dimensionally correct, and is free of nicks andburrs.122 112136b) Lightly coat the bearing seating with a thin film of oil.c) Remove the bearings (112) from their packaging.d) Wipe the preservative from the bearing (112) bore and outer diameter.e) Use an induction heater with a demagnetizing cycle to heat both bearings (112) to an inner ringtemperature of 230 °F (110 °C).f) Place both bearings (112) on the shaft (122) with the large outer races together (back-to-back).g) Position the bearings (112) on the shaft (122) against the shoulder and snug the locknut (136)against the bearings until they are cool.The locknut prevents the bearings from moving away from the shaft shoulder as they cool. Rotatethe outer bearing rings relative to each other as they are placed on the shaft to assure goodalignment.h) Remove the bearing locknut (136) after the bearings (112) are cool.3. Put the lockwasher (382) onto the shaft (122).4. Thread the locknut (136) onto the shaft (122) and tighten it until it is snug.5. Bend the tangs of the lockwasher into the slots of the locknut.6. Place the bearing-clamp ring (253B) onto the shaft (122).Make sure that the orientation of the bearing-clamp ring is correct.7. Coat the inner surfaces of the bearings with lubricant.8. Put the inboard bearing (168) onto the shaft (122).92 Model 3796 i-FRAME Installation, Operation, and Maintenance Manual
Maintenance (Continued)122168A382136253B112A9. Install the bearing housing as follows (see the illustration):a) Coat the outside of the outboard bearing (112A) with oil.b) Coat the bore of the bearing housing (134) with oil.c) Put the bearing housing (134) onto the shaft.Do not use force.253B122134112A168A10. Prepare the shaft for assembly as follows (see the illustration):a) Place the bearing-clamp ring (253B) onto the shaft (122).b) Fasten the clamp-ring bolts (236A) crosswise.See the specified torque values.Make sure that the shaft rotates freely.c) Install a new O-ring (496).d) Install the outboard labyrinth oil-seal (332A) into the bearing housing (134).Place the drain slots of the oil seal at the bottom position (6 o’clock).Make sure that the edges of the keyway are free from burrs. To protect the O-ring, cover thekeyway lengthwise with a piece of electrical tape before you install the oil seal.134253B236A332A49611. Install the shaft assembly into the bearing frame as follows (see the illustration):Model 3796 i-FRAME Installation, Operation, and Maintenance Manual 93
