VACUUM PUMP(for 8NR-FTS) 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 out.

      Tip:

      If the vacuum pump vane or vacuum pump vane caps are damaged or excessively worn out, 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.

      Tip:

      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)

      76.0 mm (3.00 in.)

      Note:

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

      Tip:

      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. Check that the areas shown in the illustration are not damaged or excessively worn out.

      

      *A

      for Type A

      *B

      for Type B

      Tip:

      If the areas shown in the illustration are damaged or excessively worn out, replace the vacuum pump assembly.
