2. Remove the spanner lock nut, dust washer,
screws, and seal adapter housing. Tap out the
seal and discard O-rings. Remove the spacers,
and discard the O-ring.
3. Remove the cap screws from the gear end
cover.
4. Remove the gear end cover using the beveled
chisel and hammer, unless jackscrew holes
have been provided.
5. Remove the snap ring from drive shaft.
6. Using the gear pullers, remove the drive shaft
bearing.
7. Remove the drive shaft.
8. Remove the gear Iock nuts and locks.
9. Align the timing marks (
See Figure 8-2
on
timing gears).
10. Rotate the drive gear in a clockwise rotation
approximately 4 or 5 teeth and mark this
location (
see Figure 8-3
). This gear position
is necessary so rotors will clear and not
jam. Do not allow the reference marks to
change location while the driven gear is being
removed.
11.
Using the gear pullers, pull the driven gear first.
12. After removal of the driven gear, continue with
pulling the drive gear.
13. Remove the gear end bearing retainer rings,
exposing the bearings.
14. Remove the cap screws and free the end
cover, exposing the oil slinger assembly.
15.
Remove the flat-head socket screw from the oil
slinger and gently pry the oil slinger from the
shaft (on some models).
16.
Remove the flat-head socket screw and
washer from the opposite rotor.
17. Use the bar pullers (
see Figure 8-4
) and
attach to free end plate bores. Using the bar
pullers, pull the free end plate from rotor shafts.
NOTE:
N
Using two bar pullers is recommended.
18. Attach the bar puller to the gear end plate bore
and push out the rotors, one at a time.
19. Using the rubber mallet, tap the end plate from
the housing.
20. Using a soft metal punch and a mallet, tap out
the bearings from the end plate bores.
21. Using a bevel chisel, remove the seals from
end plate bores.
22. On blowers with labyrinth seals installed,
remove the labyrinth seals with a beveled
chisel and hammer, if necessary.
23. Inspect all parts for wear and serviceability.
ASSEMBLY OF BLOWER
The assembly procedure is generally the same for
all series, but notations are made where there are
differences.
Gaskets are never used between rotor housing and
end plates. Gaskets are used on 16/47 and 17/46
series between the end covers and end plates to
seal oil leakage. Dowel pins are used to locate the
end plates, housing, and drive end cover in proper
location relative to each other. Be sure the dowel
pins are in place.
It is recommended that the gear end rotor shaft
bearings be purchased from Tuthill Vacuum &
Blower Systems, as they are specially ground to
locate the rotors with correct end clearance relative
to the gear end plate.
