How To Install A Labyrinth Seal

12

NOTE: No shaft support is needed; the shaft volition exist supported
by the labyrinth seals.

Bearing Replacement Procedure

CAuTIOn: Maintain extreme cleanliness to avert bearing

contagion and damage. use new gaskets.

i. Install components in the opposite order of disassembly.
2. Press the bearing onto the shaft until seated confronting the

shoulder. Pusher kits are available from Spencer.

NOTE: If present, oil slinger 'dimples' should confront the

bearing.

3. Lubricate according to instructions on pages 8 and 9.

Series 3000, 4000, 5000, 6000

Bearing Removal Procedure

ane. Remove coupling guard.
2. Split the coupling halves, recording the relative position of

the motor and blower shafts (not the coupling shells).

3. Unbolt and motility motor.
4. Use puller to remove blower coupling half. Apply heat if

necessary.

5. For oil-lubricated begetting, drain all oil by removing drain

plug from the bottom of the bearing sump.

half dozen. For oil-lubricated begetting, disconnect oiler tubing and oiler

if necessary.

7. Remove bearing cap.
8. Remove shaft locknut and lockwasher.
9. Remove begetting housing bolts.
10. Using a two-arm puller and the two tapped puller holes

(5/8") in the begetting housing, remove housing, bearing(s)
and bronze seal, if present, as a unit of measurement.

eleven. 'Migrate' the bearing(s) out of the housing.

NOTE: No shaft back up is needed; the shaft volition be sup-
ported by the labyrinth seals.

Bearing Replacement Procedure

CAuTIOn: Maintain extreme cleanliness to avoid begetting

contamination and damage. use new gaskets.

1. Install components in the reverse order of disassembly.

Notation: If the assembly is equipped with a statuary rotation

shaft seal, start the seal on the shaft, merely practise not seat.

2. Printing the bearing(due south) onto the shaft until seated against

the shoulder. Pusher kits are available from Spencer.

Notation: Double bearings must be installed back-to-back.

iii. Lubricate according to instructions on page 9.

Series 7000, 8000

Bearing Removal Process

ane. Remove coupling baby-sit.
ii. Dissever the coupling halves, recording the relative position of

the motor and blower shafts (not the coupling shells).

3. Unbolt and move motor.
four. Utilise puller to remove blower coupling one-half. Apply heat if

necessary.

5. Drain all oil by removing drain plug from the lesser of the

begetting sump.

six. Remove begetting cap.

vii. Remove slinger cover, shaft locknut,

lockwasher, spacer, oil slinger, and
bearing retainer.

viii. Open a section of the ball cage on the

bearing and cut the swarf out.

9. Using a blind housing puller kit (avail-

able from Spencer), insert the appro-
priate bearing adapter and rotate information technology
90 degrees to achieve a positive grip
within the bearing race.

ten. Prepare the opposite cage area in the

aforementioned fashion and insert the 2d
adapter.

11. Connect both adapters to the main rod.

Assemble beam and spindle.

12. Pull out begetting.

NOTE: No shaft support is needed; the shaft will be supported
past the labyrinth seals.

Bearing Replacement Procedure

Caution: Maintain extreme cleanliness to avoid bearing

contagion and harm. employ new gaskets.

ane. Install components in the reverse order of disassembly.
2. Heat the bearing. Normally a bearing temperature of 80 to

90 °C (144 to 162 °F) to a higher place that of the shaft is sufficient for
mounting.

CAuTIOn: never estrus a begetting to a temperature

greater than 125 °C (257 °F), never rut a bearing

using an open flame.

3. Press the bearing onto the shaft until seated against the

shoulder. Pusher kits are available from Spencer.

NOTE: Oil slinger 'dimples' should face the bearing.

4. Lubricate according to instructions on page 7.

Labyrinth Seal Removal and

Replacement

NOTE: Labyrinth seals are non-contacting and do not clothing,

but if a seal is damaged during bearing replacement, leakage

will increase and the seal should be replaced.

one. Remove the begetting housing,

following the appropriate bear-

ing removal instructions in this

manual.

2. Remove the oestrus fan if pres-

ent. Disk-type heat fans are

secured by two setscrews;

bladed heat fans are clamped

to the shaft.

three. Back up the shaft and slide the

seal articulate. Gently lower the

shaft.

4. Slide the new seal onto the

shaft, raise and recenter the

shaft, then seat the seal and

fasten securely.

Caution: use care; the seal cloth is soft and

hands damaged.

5. Disk-blazon heat fan: Employ a feeler gage to position the fan

.050" from the seal face and tighten.

Bladed heat fan: Center the fan betwixt the seal face and

the bearing journal and tighten.

6. Replace begetting(south) following the appropriate bearing

replacement instructions in this manual.
