Vacuum Pump (For 1Gd-Ftv) Inspection

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

HINT:

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

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

Minimum length A:

23.8 mm (0.937 in.)

NOTICE:

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

HINT:

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

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

Minimum length B:

85.0 mm (3.35 in.)

NOTICE:

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

HINT:

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

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

NOTICE:

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