This component has been designed for high-speed applications to enable large amounts of torque to be safely transmitted to the rear wheels of a Lotus Elan, Elan +2 or single seater race-car.
This offers the following benefits:
· Effectively transmits large amounts of torque for high speed applications
· Produces smoother drive shaft motion particularly during take-off
· Eliminates any orbital motion caused by out-of-balance condition of the intermediate drive shaft
· Fail safe design in the event of drive shaft coupling failure
· Extends drive shaft coupling life under normal road and racing conditions
Centring plate for Rotoflex coupling
The centring device illustrated below has been carefully designed to be installed in your existing driveline without adding significant extra-unsprung weight.
· Weight - 160 grams
· Material - Mild steel housing and centre plate
· TIG welded bearing housing
· High quality radial sperical bearing
· Retaining circlip allows spherical bearing to be replaced.
· Epoxy black paint protective finish
· Race proven product.
It is recommended that all drive shafts should be crack tested before any modifications are performed.
This modification requires the inboard and outboard drive shafts to have a high tensile steel pin installed in them.
This requires the shafts to be counter-bored to accept the high tensile pins (press fit).
The centre pin is then TIG welded to the drive shaft and then machined to be parallel with the drive shaft axis.
