(5) Check sliding sleeve (B) against the limits

specified in the repair standards (para 3-60) and

replace the sleeve when it does not meet these

requirements. Inspect the bearing face of the sleeve

to determine the depth of any indentations. When

indentations exceed 0.008 -inch, replace the sliding

sleeve.

(6) Examine the operating shaft bearing (Z) for

burs, nicks, and scratches on the gasket surface and

hub diameter. Repair minor burs, nicks, and

scratches with a fine mill file or crocus cloth. Replace

the operating shaft bearing when any of these

conditions are excessive. Check the operating shaft

bearing against the limits specified in the repair

standards (para 3-60) and replace the bearing when it

does not meet these requirements.

(7) Inspect the operating shaft (FF) and shaft

spring plate (EE) for wear and replace any worn part

or parts. Check parts against the limits specified in

the repair standards (para 3-60) and replace parts

when they do not meet these requirements. Examine

the ends of the operating shaft spring (W) for wear

and indentations. When the spring ends are worn or

have indentations that exceed 0.004-inch, replace the
