Disassembly and Reassembly Instructions
Operator’s Manual 2010 Rev B p/n 2010
ASSEMBLY (6000 SERIES)
A maintenance kit is available from Tuthill Vacuum
and Blower Systems. This kit contains all the
components that are replaced during a normal
blower overhaul. As a minimum, these parts should
be on hand prior to assembly. Be certain to have
your serial number available when you contact the
factory.
Check all parts to insure they are clean and free
of burrs or nicks that may have occurred when
the blower was being disassembled. Check the
repair kit for the correct parts needed to complete
the assembly of the unit. Make sure you have the
proper tooling and training required to assemble
the blower. Take the proper time to read the
instruction manual before you begin.
Gear End Assembly (6000 Series)
1. Seat rotors on a fixture with the gear end of
the rotors upward and with the rotor keyways
pointing toward the 9 o’clock position. Make
sure that the drive rotor is in the correct
location for the proper flow and rotation
required for the application.
2.
See Figure 6-5
regarding bearing bore stack-
up and seal measurement.
3. Using a seal pressing tool, press the piston
carrier onto the rotor shaft, and sleeves into the
bores of endplates. Seat endplate over rotors.
Install seal slingers and add shims as needed.
4. Install bearings and press until seated. Install
retainer and bolts. Install gear spacer onto
long-tail rotor.
5. Install keys into shaft. Install solid gear onto
long-tail rotor and two-piece gear hub onto
driven rotor. Install two-piece gear over hub.
Install lock washers and screws into gear.
Install rotor washers and screws over gears.
6. Check clearances. Add O-ring to housing. Add
entire assembly to housing and bolt together.
Drive End (Free End) Assembly

feeler gauges check the free end for proper
clearances. Add shims to get proper free end
clearances. Install O-ring into groove.
2. Install piston carriers onto rotor shafts and
sleeves into endplate bores.
3. Install endplate over rotor shafts and bolt to the
housing.
4. With a feeler gauge, check free end clearance.
Adjust with shims appropriately.
5. Install slingers onto each shaft and add .060 in.
shims to each shaft. Install bearings.
6. Add bearing spacers. Install washers and
bolts to hold bearing spacers. Add the inner
