Using an undersized puller doesn’t just risk failure, it can also lead to more time and frustration than simply choosing the correctly rated tool from the start.
The Frame Flexes Under Load
Visible flexing or bending in the puller’s frame is a clear sign it’s being pushed beyond its intended capacity.
The Screw Binds or Strains Excessively
A forcing screw that strains heavily well before the job is done often indicates the tool doesn’t have the capacity for the task.
Reach or Spread Falls Short
If jaws can’t fully seat or the screw bottoms out before contact, the puller’s dimensions simply don’t match the job, regardless of its tonnage rating.
