2fl of Hydrovac goodness!

Did some PM's on the 353.. mostly brake stuff.

TM says put in 2fl oz of oil to keep the hydrovac felt and leather supple and make a seal.

FYI 2 fl oz is approx 1/4 cup. I use Permatex hydraulic oil. Comes in quarts at places like Tractor Supply. Looks like 1 qt will last a couple of years.

1/4 Cup is incorrect, consult your TM and LO again.

1 FL Oz for the rear, and 2x 1/2Oz for the center plate.

1 + .5 + .5 = 2 Fl Oz

(9) HYDROVAC CYLINDER. Lubricate every 6,000 miles with
(SA) shock absorber fluid, light. Remove pipe plug at center of rear
shell, also plug from inside elbow at center plate. Apply 1/2 oz of
lubricant through each plug opening.
Replace plugs. To insure
proper spread of lubricant in cylinder, start engine and make 3 or 4
severe brake applications. Early vehicles are equipped with vacuum
cylinder at left side of vehicle. Every 6,000 miles, remove plug in
rear of cylinder and apply 1 oz (SA) shock absorber fluid through
plug opening.
Replace plug. Every 1,000 miles lubricate idler lever,
ahead of vacuum cylinder, with (CG) general purpose grease, sea-
sonal grade.

I 'splain things a bit different I guess.
