Hi-Lo Retrokit New Britain

New Britain9
New Logan Hi-Lo Retrokit and Hi-Speed Conversion Kits for your New Britain increase your machines daily and weekly output from 10%-20% - leaving you room for additional capacity, productivity, and profitability. Positive, fast-acting Logan Clutch engagement enables your New Britain to change speeds much faster and provides a more consistent and accurate cycle time than conventional mechanical clutch methods.


New! Roll Clutch Removal Feature Increases Productivity


Mechanical Roll or Rollaway clutches have a tendency to slip and grab at different points during speed changes and indexes. This causes expensive tool breakage and downtime when the machine goes past low-point in high-speed. Because Logan clutches improve cycle time repeatability, our new low-speed clutch feature replaces the old-style roll clutch. This enables set-up personnel to position tools closer to the workpiece, further reducing dwell time and overall cycle time.

Hi-Lo Retrokit Features:

  • Reduces the idle time between speed changes.
  • Replaces mechanical clutches, roll clutch, band brake, and linkages with fast-acting air-actuated Logan Clutches.
  • Positive, crisp Logan Clutch engagement guarantees cycle time repeatability.
  • Simplifies clutch maintenance - No disc pack adjustment or slippage.
  • Quick-stop, power-applied brake Prevents machine coasting.
  • New! Low-speed clutch design reduces idle time - Machine operates more consistently.


  • Increase productivity from 10-20%.
  • Tools can be positioned closer to the workpiece due to repeatable high and low-speed clutch engagement.
  • Better machine utilization - More productivity from existing machines, operators, and floor space.
Davenport Timing Chart rv-1465916156

View of a typical Davenport timing chart. As you know, Davenports rotate counter clockwise. The Logan Hi-Lo Retrokit enables your Davenport to enter into high speed a few degrees earlier (55 degrees vs. 60 degrees) and stay in high longer (95 degrees vs. 92.5 degrees), thereby allowing your machine to “get back into cut” much faster. It takes less time to get back into the cut, over a period of millions of parts – which increases your machines overall productivity using the same operator, machine and floor space.

Overall, these basic speed changes enable your Davenport to improve cycle time by 10%, and sometimes more depending upon the job.
