Flexing gearbox outer cover on Indian
It's well known that the gearbox outer cover of the four
speed Albion type gearbox is not strong enough.
This in itself wouldn't be a problem, but this couple of millimeters flex robs the clutch push rod of that amount of movement and the mechanism is short of movement as it is. This is one reason that the RE classic clutch can be tricky to set up correctly and can start to drag when it gets hot (e.g. in traffic)
Obviously it's a
good idea to eliminate this movement if you can.
One way is to extend one of the main bearing bolts out
through the cover but I think the hole you need to drill in the cover is a
bit close to the inspection hole for comfort.
This is what I did;
Steel strip mounted on brass spacers between the main bearing cap bolt and the inner cover fixing screw ( with suitable longer screws)
20mm X 3mm steel
strip drilled at each end 1/4" with 6mm tapped hole at centre.
spacers 1/2" OD, 1/4" ID
Drilling the cover.
I drilled at the centre of the cast-in webs as I thought it might be
I used a button
headed screw to keep the profile as low as possible to clear the
Clears the neutral finder lever nicely.
I'm quite surprised there's room for
this under the cover but nothing fouls so I'll call it good.
UPDATE 1000 miles on
Hitchcocks are now selling a version of this mod for £15 (but it's more satisfying to DIY)
