Liftmaster 144C54 Pulley
Liftmaster 144C54 Pulley
Came the day they said and worked fine.
This replaced the old one no problem for a craftsman model 139.5391D. I replaced it with the belt because they both were pretty old. The metal motor unit sprocket was ok. This unit was made by either lift master or Chamberlain for Sears.
Exact part needed for repair; timely delivery.
Had to be an OEM part as it fit perfectly.
The pulley was just the one I needed for my door openers
