Wood Casement Window Operator 39-268

Does the cap that houses the crank arm and worm gear drive have a removal screw (accessible), or is it press fitted
(no accessible) for grease and lube purposes?

Thanks much Casey. Steve was helpful, but directed me to your department for this answer. Glad your company still supplies these.
(I'm servicing/replacing some that have been in the home since 1950?17 windows) Merry Christmas to all. Peace and Blessings,
Clyde
