KK Casement Operator

Question

Need to replace a number of KK window mechanisms in 35 year old log home in Wisconsin. Most come off track and cannot be closed for inside house. Photo of one crank unit is completely broken. quantity TBD (estimate 16+)

Photos added show broken crank as well as the arm that is off track. Let me know if you can capture the part numbers.

I believe you have either the 39-031 and 39-032, or the 39-155 and 39-156. The only difference between these two sets of operators is the length of the link arms, so compare both with your old hardware to see what matches best.
