  • The problems with these units are widely known and acknowledged.
  • They were fine when they were new but now they are regarded as a ‘pain’ !
  • The need for specialist tools or big hydraulic presses to dissemble.
  • That they are very hard to build and maintain the bearing end float.
  • The flange becomes thinner as they have to be skimmed due to distortion.
  • The Yoke UJ diameters become bigger the more they are dissembled and reassembled.
  • In addition the flanges are known to crack and fail.
  • And the holding thread to the shaft shears.

THE  REDESIGNED,  MADE FROM NEW COMPONENTS,  TRIUMPH REAR HUB UNITS  SOLVE THESE PROBLEMS AND PROVIDE IMPORTANT UPGRADES.

  • Splined shaft and flange construction does not need ‘big’ pullers to separate
  • Bearings are solidly spaced using shim washers so do not go out of adjustment
  • Wear compensation is easily accomplished with DIY tools.
  • Because of this the flanges are not distorted so do not need skimming.
  • And driveshaft joints do not need to be disassembled so often
  • Thread to shaft diameter is increased by  85%
  • Flange design has increased diameters and radii to stop cracking and failure.
  • Bearing sizes are increased and bearing design has been validated by Timken UK.
  • Only Top quality materials, bearings and seals are used.
  • No Cheap Far East bits!
