If damage has occurred from shipment a claim must be filed with the carrier immediately; preserve the shipping container for inspection by the carrier. Do not return the booster to the factory without first obtaining shipping instructions from Tuthill Vacuum Systems. Remove protective covers and plugs only as connections are made. -

Page 7: Water Liquid Cooling Instructions
Kinney KV-100 oil is recommended for use on boosters with typical vacuum applications. Consult Tuthill Vacuum Systems on oils for use where hazardous or chemically active materials may be present. Add vacuum oil to the booster in the quality shown in Specifications on page 2. -
Page 8: Water Cooled End Plate Option
Figure 3 Cooling Water Piping Harness The partly water-cooled slinger seal version has cooling water to the seal adapter housing only. The cooling coils and interconnecting water line are omitted and the interconnecting line leading from the seal adapter housing is led to the drain. The air-cooled configuration requires no cooling water. -

1) Disconnect cooling water lines (274 & 181). Do not disturb DISASSEMBLY cover bushings (120) or it will be necessary to retest cooling coils KMBD-240C & for leakage as described in the assembly procedure. Covers KMBD-400C should be re-tested if water is detected in drain oil, (mechanical seal boosters only). - Page 14 11) Turn the unit around and attach a single bar puller to either bore and push rotor from end plate making sure the rotor is vertical in the housing (for support) while removing. Repeat for opposite rotor. Note the location of timing shims (16), oil slinger (20), and spacers (17 &...

Be sure they are in place. It is recommended that the gear end rotor shaft bearings be purchased from Tuthill Vacuum Systems, as they are specially ground to locate the rotors with correct end clearance relative to the gear end plate. Do not use standard bearings which have not been flush ground within .001 tolerance. - Page 16 It is suggested that long feeler gauges (12”) be used to check the interlobe timing. Preferably (2) .006, (1) .005, (1) .004, and (1) .003 These gauges will provide all the combinations from .003 to .021, and also .024, which is the total. 1) Remove all nicks, scratches, etc.
- Page 17 6) Lubricate shafts and press the double row ball bearings (9) onto rotor shafts and into end plate bores. CAUTION: These bearings have been flush ground at the factory. The inner race will have a black dot etched on the surface.
- Page 18 14) Mechanical Seal Boosters– Install mating rings same as gear end, No. 5. Slinger Seal Boosters – Install seal slinger same as gear end. Install bearing spacers (123) on each shaft. 15) Lubricate shafts and install roller bearings (10). CAUTION: Inner race of bearing has a flange on one side only. This flange must face outward.
- Page 19 25) Install free end cover (7) following the same procedure used to Complete Booster install the gear cover. Secure with cap screws (26B). Assembly 26) Apply sealer and install both port fittings (38 or 48). 27) Install all necessary cooling water lines. 28) Prior to putting booster into operation, follow Installation and Operation instructions.

10) Remove cap screws (62), locks (61), and bearing lock rings (14). 11) Install two screws temporarily to hold end plate to housing. 12) Remove the free end cover (7) rotor shaft socket screws (26 & 69), washer (25), spacer (57), oil slinger (21) (must be pried off on KMBD-850C, 1200C, 1600C, 2000C, 2700C models), roll or dowel pin (68), socket head screws (30) and oil retainer rings (14 &... - Page 22 It is recommended that the gear end rotor shaft bearings be purchased from Tuthill Vacuum Systems, as they are specially ground to locate the rotors with correct end clearance relative to the gear end plate. Do not use standard bearings which have not been flush ground within .001 tolerance.
- Page 23 rest on top of carbon. Gently press with fingers to insure compression is taking place and ring is not hung up for any reason. Slinger Seal Boosters – Slide slinger (238) over shaft. Also install spacer (129) if two piece. 6) Lubricate shafts and press the double row ball bearings (9) onto rotor shafts and into end plate bores.
- Page 24 16) Install oil retainer rings and screws (14 & 30, spacer (57) (model 540C & 720C only), washer (25), screw (29), oil slinger and dowel (21 & 68), and screw (69). NOTE: Oil slinger should always be mounted on lower rotor for horizontal flow units.
