VACUUM PUMP(for 2GR-FKS) INSPECTION

PROCEDURE

1. INSPECT VACUUM PUMP VANE

   
   
   1. 

      *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.

      Tech Tips

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

   2. 

      *a	10 mm (0.394 in.)

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

      Minimum Length (A)
      23.8 mm (0.937 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.

   3. 

      *1	Vacuum Pump Vane
      *2	Vacuum Pump Vane Cap
      *a	5 mm (0.197 in.)

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

      Minimum Length (B)
      80.5 mm (3.17 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.
