Getting Pushy–Jacking Bolts Revisited
By Stan Riddle
Jacking bolts provide a smoother, easier way of moving machinery than using pry bars and hammers. Their use will almost always speed up the alignment process, prevent excessive minor moves back and forth, and generally make the task of shaft alignment much more pleasant. More and more companies are realizing the benefits of using jacking bolts to accurately position machines.
What about you?
Jacking bolts can be purchased, or made in-house. Here are a few examples of some pusher types:
A C-clamp Weld a nut or tapped block to the side of the C-clamp. The clamp can then be mounted to the frame of the machine. The can be made in many different configurations, and can be removed after the shaft alignment is completed.
A dowel type The base can be drilled to accept a piece of rod, which has been drilled and tapped to accept a bolt. This can also be removed after the shaft alignment is completed, or left in place.
A channel Drill and tap a piece of channel of the machine frame, and use a bolt or threaded rod to move the motor.
