Bristol 400 rear axle gears
Dorien as it happens mine is noisy (they all seem to be) and I'm
sending it to Norman Geeson who you can read about on
www.kda132.com For many years he's specialised in overhauling and
raising the ratios of Post War Rolls-Royce and Bentley rear axles
and he does them for all the top specialists.
He's already done a 403 for someone in the club who'd twice had his
overhauled by axle or Bristol specialists and they'd done so much
damage he had to buy another Crown Wheel and Pinion. Norman did it
properly and it was quiet too.
Norman will have taper rollers ground to fit, he has the special tools
necessary to build the thing and he will spin mine up on the gear
cutter's test rig to find the the quietest setting.
Obviously your being in Canada makes it impractical to have Norman do
it, but once he's done mine, which is possible the same as yours with
the screw in pinion bearing housing, he'll have the bits you need and
be able to talk you through it.
I hope to have it out before Christmas but am currently fitting a
rebuilt Close Ratio Gearbox and MGB Clutch, so would like to see what
it's like before I dismantle it again.
I plan to tour France in it next year (we've five places left if
anyone would like to join us - please email me for details) and would
to reduce the noise as much as possible and be sure that it doesn't
brake down.
