Bearing Puller guide: choose right puller for your work | DNT Auto Tools FAQ

DNT pullers are manufactured to a very high specification and subjected to rigorous testing - far exceeding their stated capacities. The legs and beams are drop forged from high quality steel and then heat treated for extra strength and durability. Pullers are normally classified as either hydraulic or mechanical with many different types within these two styles

What's a Basic components of a hydraulic system | DNT Auto Tools FAQ

A hydraulic puller system needs 3 basic components to function: 

Basic components of a hydraulic system 

1.Puller

2. Hydraulic Cylinde

3. Pump (Air, hand, self-contained or electric) 


The basic operation of a hydraulic puller system makes use of a cylinder that is fitted into the  body of the puller. The cylinder replaces the center bolt function of a manual puller. 


 The technician inspects the component to be removed and selects the proper size puller. Safety  precautions are taken in into consideration as the technician secures the jaws of the puller on the  application to keep the system in place. 


 Instead of using a wrench to move the center bolt forward and backward as one would with a  manual puller, a pump is used as a power source. The pump regulates the flow of hydraulic fluid. 


As the hydraulic fluid pressure builds up, the pressure moves the cylinder forward pushing the  ram of the puller to make contact with the shaft of the component being removed.
