The handle for the casement window keeps falling off, and the stud that it goes onto appears worn. Also the plastic cover over the mechanism is cracked. This is the mechanism for a Marvin wood-framed casement window. Inside the cracked cover is the word "Truth." I think I need a new crank handle, a new plastic cover, and a new mechanism that the handle connects to.
Thanks in advance for the help.

Hello,
It sounds like the spline the handle attaches to may be stripped. Unforutnately, that part can't be replaced so you would need the entire operator.
Your photos resemble the 39-031 and 39-032 EntryGard operators but make sure the dimensions below match yours, paying close attention to the length of the shorter link arm. We also offer the 39-107 cover and 39-114L handle if needed, or the 39-107FK for a low-profile option. Thanks for posting!
