HELP NEEDED!
I am currently trying to get a new pair of gears made to fit the transfer
box on my 6.1 litre aero engined pre-war Riley. The trouble is that the
gear cutting people are taking about 1000 pounds to have a pair cut heat
treated and ground. The current gears and box are I beleive a PTO off a
tractor.
As an alternative I have thought of using the Crown wheel and drive gear
from a transverse front wheel drive car. The quality should be good, spare
cheap, easy to get hold of. The trouble is finding what I want without
dismantling every box in the local breakers yard.
What I need is a pair of helical gears (not a 90 degree set like the CWP
in a rear axle) that run in the same axis. Ratio needs to be 3.3:1, centre
distance approx 105 - 115 mm (4" to 4.5") aboiut 40mm/1.5" wide.
All dimensions approximate, does anyone have any good ideas? Anyone who
comes up with something that I end up using can go for a spin down the
road in the car!!!!
cheers
Geraint
