Gearbox Removal - Atlas

If the inner primary case is removed (this implies clutch, engine sprocket, etc are removed), and the drive sprocket removed, can the gearbox be removed without removing the engine?

Slick

7.06.14 I found the answer in my Norton Service Manual. NO!

THE ATLAS SHAKES

I have been asked:

"Hi slick

You've had an atlas over fifty years, do they really shake the filling out your teeth, so to speak?

When mschmit told me john Hudson repaired nortons with 1960,s dental tools it made me wonder."


My first Atlas was a '62... a pretty bike with only about 1800 miles if I remember correctly. My Beezer and Trumpet buddies tried to dissuade me from buying it, saying Nortons shook bits off and left them lying in the road. The first thing I noticed was it did not shake any worse than the 650 BSA's and Bonnie's. The next thing I noticed was it could barely beat them out in a zero to ton contest.

I then traded for a new '63. First thing I noticed was it beat the crap out of those same BSA's and Bonnie's.
Next thing I noticed was it was more intractable than the '62, but I cannot say it was any worse in the vibration area.

It definitely does not leave any parts on the road. My Bonnie buddy used to weekly go around his bike tightening up all the fasteners, something I never did. Once I burned out the Brit bulbs, I replaced them with Made in USA equivalents, and never replaced bulbs on any more frequent basis than I do in my cars.

To be sure, it is no Commando, but OTH Commandos are not Featherbeds either.

At 70 MPH, the handle bar vibes are such that the mirrors are worthless, but 60 MPH is a more efficient cruise speed both in terms of saving fuel, and saving my energy to hold on against the wind, and at that speed, the vibes are no worse than other big verticals.

Sure, I would like to have a Featherbed Roadholder, smooth as a Commando. But I think the Atlas has been given a bum rap. What sayeth other Atlas guys???

Slick

PS: I never lost any fillings from the Atlas.

As well as Commandos I also did some serious touring on my 63 650SS not an Atlas but close.
I probably enjoyed touring on the 650 more than Commando's.

After 5 years of work my 65 Atlas is now on the road and quite frankly it doesn't seem much worse than my 71 T120. After I get more ride time on it I'd like to take it on a trip.

Slick if you want to get rid of your handle bar vibrations do what I did to my 850 Featherbed, I replaced my handle bars with a set of Renthal bars they are alloy 6mm walled, nomal bars are only 2mm walled thick, since doing this I can ride at any speed without any vibrations in the bars and they were near the same price as nomal bars, my old bars only vibrated at certin speeds and not all the time, but the Renol bars fixed all that.

Re: Atlas photo posted by P400:

I notice the speedo cable is routed upwards .... if I remember correctly, mine was factory mounted horizontal along the swingarm, along the lower frame tube, then upwards to the headlight bucket. I routed mine as in the photo, but parallel to the rear damper to hide it from view.

The '62 & '63 had the speedo mounted in the headlight bucket. both my '62 & '63 came without tach, although I believe that was an option, but probably dealer installed.

I considered it improper for any manly British Twin to not have both clocks on top of the triple tree, so I mounted my mine there....purists reading this may spit now.

What did I do with the hole in the headlight bucket? Just plugged it with a flat plate, but when the Lucas Headlight switch crapped out, and the steady alternator output boiled over the battery, taking the chrome off the primary chain case cover, and left silencer, I mounted dual 3 position rocker switches in the flat plate to have the function PILOT-OFF-MAIN headlight and LOW-OFF-FULL alternator function. Purists can spit again.
