Gearbox Selector Fork Rebuilding.
Posted: Fri Apr 13, 2012 11:58 am
Further to gear box overhaul and rebuild work, pictures
below show 3rd & 4th gear selector, note the amount of wear
on the face.
Re building was done with Oxy and wear resistant
silver braze rod, this is a low melting point braze material
which means the metal deposit can be applied below the
heat point at which bronze will begin to sag.
Gear selector forks are often die cast in Aluminium bronze
which can be tricky to repair with nickel bronze.
With the correct metal preparation & technique the repair
can be done quite easily, the hard part is the careful hand
filing required. These reconditioned selector forks should
last for many more years.
I would not be at all surprised if many elan gearboxes
have badly worn selector forks considering the age
of them now.
