31876 Replacement Operator

Hello,

Take a look at the newer version of your operator, which would be the 39-253LB. This operator should match up to the one shown in your photo. With this newer operator, you will need to order the cover with the attached handle such as the 39-451 or the folding handle and cover, 39-375. 

I would suggest replacing the 39-529 track slider because it could be worn. As for the 39-546 stud bracket, you should be able to reuse that. Just check to see if it is also worn. Take a look at the 39-253LB along with the other related parts and videos. Thank you!
