Safely and efficiently remove 789 and 793 ball studs with Geographe’s newest product innovation.  Geographe have been supplying ball stud kits to suit Caterpillar 789 and 793 trucks for many years now, but have recently developed a tool to aid in their removal.

 

HOW DOES IT WORK?
Geographe’s patented Ball Stud Removal Tool (BSRT) is a hydraulic pressing system for safely and efficiently removing ball studs from 789/793 series haul trucks using pressure applied to the bottom or threaded end of the stud.

HOW DOES IT PERFORM?
In field testing, the BSRT has been removing studs at a significantly faster rate than the current industry norms.  Success rates will vary however our customers have reported an average 70% success rate on removing studs on first attempt.   With a correctly positioned truck, up to 4 studs being removed in 20 minutes has been achieved.  Actual times will vary based on individual trucks condition and how they are set up for maintenance.

IS IT EASY TO USE?
One of the key qualities of Geographe’s BSRT is its ease and safety of use.  It has been design to be a single person operation tool and  a full user manual is provided to help get the most from the tool.   Its general ease of use is summarised in 5 simple steps below:

  1. Undo the ball stud nut and back it off by two full turns
  2. Remove any excess grease on the top of the bell crank
  3. Simply slide on the tool which weighs only 19.5kgs
  4. Insert the hydraulic ram onto ram retaining points
  5. Fit the tool retaining bracket and pin and you’re ready to go.

A demonstration video filmed in a workshop setting can be seen below:

 

Real world removal scenarios will be different and considerations to be aware of include:

  • Tie Rod to Bell Crank Gap – If the truck is not manipulated to allow the gap to be as parallel as possible the tool won’t fit.  I.E. if tie rod is on too much of an angle.
  • Tie Rod Adjustment Clamp – The clamps sometimes need to be released and moved back to allow the tool to be fitted.
  • Steering Cylinder Type – Some larger diameter steering cylinders restrict fitment of the tool.
  • Steering Position – Manipulating the steering/wheel angle can relax axial forces on the ball studs, assisting their release.
  •  Availability of 10,000 PSI Hydraulic Pressure – The tools hydraulic ram is reliant on this maximum pressure and we have discovered some sites do not have this ability.

As part of our continuous improvement process since filming the video above, we have up-rated the tool for increased hydraulic pressure to 50T. 

Recent feedback we have received:

“Mate just some feed back on the updated ball stud tool, we are very pleased with the upgraded tool performance.

We are finding that it is working very well and haven’t found any yet that it hasn’t worked on, only one we had to apply a small amount of heat to the taper to make it pop.”
