It appears that the procedure on page 12 is the correct one for the 2- 45's version.
The reason that they say to leave the test oscillator at 175 KHz for the high freq alignment is that they are using the 8th harmonic of the osc to provide the 1400 KHz signal ( 8 x 175 = 1400 ).
I guess that test osc only generated low freq signals so, the 1400 could not be supplied as a fundamental output.
You can of course use your generator to provide 1400 directly, or for greater dial calibration accuracy use a known broadcast station near 1400 to adjust the local osc on freq.
