Hello Mike
=20
Can you please let us know how the magnet is fitted to the gearbox drain =
plug for a sideshift box.
=20
They can be purchased complete from Denis Welsh for =C2=A39.95 plus =
postage, but would be interested in doing my own.
=20
Thanks

Quite correct Bob,=20
However I believe the premature failure of the laygear needle bearings =
is caused by circulation of the microscopic chips of hardened steel that =
are shed by the 1st, reverse and laygear when people grind them =
together.=20
To minimize this I always install a magnet on the gearbox drain plug to =
supplement the overdrive one.=20
I have been restoring (replacing) the 1st gear section of MG "T" series =
gearboxes for several years for which we have been using a tougher steel =
alloy for the replacement 1st gear. To date have experienced no =
failures, even in boxes that have been raced extensively.=20
I would presume that the people doing the Healey laygears are using =
similar material.

ps. The only laygears I've seen advertised were 'rebuilt'--i.e. welded=20
together--is there a source now for new laygears?
