      *1 Vacuum Pump Vane Cap
      *2 Vacuum Pump Vane

      Check that the vacuum pump vane or vacuum pump vane caps are not damaged or excessively worn out.

      Tech Tips

      If the vacuum pump vane or vacuum pump vane caps are damaged or excessively worn out, replace the damaged parts with new ones.

    2. A010M4ME01

      Using a micrometer, measure length A of the vacuum pump vane with the vacuum pump vane caps removed.

      Length A
      Vacuum Pump Assembly Minimum
      for Type A 23.8 mm (0.937 in.)
      for Type B 25.8 mm (1.02 in.)

      Note

      Measure the length 10 mm (0.394 in.) in from each end of the vacuum pump vane.

      Tech Tips

      If the length is not as specified, replace the vacuum pump vane and vacuum pump vane caps with new ones.

      *1 Vacuum Pump Vane
      *2 Vacuum Vane Cap

      Using a vernier caliper, measure length B of the vacuum pump vane with the vacuum pump vane caps installed.

      Length B
      Vacuum Pump Assembly Minimum
      for Type A 76.0 mm (3.00 in.)
      for Type B 78.0 mm (3.07 in.)

      Note

      Measure the length 5 mm (0.197 in.) in from each end of the vacuum pump vane caps.

      Tech Tips

      If the length is not as specified, replace the vacuum pump vane and vacuum pump vane caps with new ones.

  2. INSPECT VACUUM PUMP HOUSING


    1. A010IKZ

      Check that the rotor part, coupling, vacuum pump housing or vacuum end cover is not damaged or excessively worn out.

      Tech Tips

      If the rotor part, coupling, vacuum pump housing or vacuum end cover is damaged or excessively worn out, replace the vacuum pump assembly.
