Hi there,
I have heard somewhere that it is now recommended to use new Nyloc nuts on the bolts holding the Layrub Couplings. Thus would avoid the pain of getting the original castellated nuts to line up and result in the correct torque settings.
Can anyone confirm this as a good idea and recommended practice?
Many thanks,
David

They have been on Jen's Javelin for 30 years.
On the Jupiter I do not use Nyloc; but use Loctite rather than pins for locking. In many years of competition, I have had no problem.
The MOT person may fail the car, if he sees a castellated nut without a pin. they should be so tight anyway that they should not shake loose.
One issue may be balancing the shaft, as the Nyloc may be heavier than the original.

Altering the weight at one end of the shaft would alter the centre of gravity of the shaft and hence its balance. The shaft axis of rotation may well not pass through its CG, thus even if the layrub nuts are balanced around their axis of rotation they may alter the balance of the whole shaft's balance. Anyway there may be play and other angular or positional differences that mean the layrub CG is not actually on the axis of its rotation. After all it is a rubber joint!

Layrub Couplings
Hi there,
Thanks for all the advice. It looks as if the summary of the useful tips that have come in is that, if I replace all the couplings (as I had planned to do anyway as they are all look a bit tired and I managed to pick up some new ones from an autojumble) and use new Nylock nuts, then everything should be OK?
Many thanks,
David
