classic motorcycle forum

Im trying to identify parts of this bike for an artical Im scratching together .
chassis = 49 - 52- Indian scout , motor = crocker ,  trans = HD predate electra-glide.
fuel tank = looks brit ??
oil tank = brit ??

HD clutch = 37 tooth 2 row that requires 428-2 chain , that requires 2 row motor sprocket for 1" taper motor shaft = pre 1954 HD sprocket  , tin primary case .
trans out put = HD therefore 530 rear chain

usually motor has magneto out front BUT notice there is a tail and head light ?  there fore , there is power or a total loss battery strapped on but not visable thru rear wheel ?? . magneto could be replaced by gen . there was a dizzy also available for there motors , which would need a gen which was driven off stock clutch basket which this is not . it was an autolite clock wise rot.
HD usually had gen off front of motor driven by the timing gears .
motor has 2 separate oil pumps which are the copper pipes up the guts centre .

HD primary has no allowance for dynamo take off drive or pulley
under the tank theres a wire parallel to down tube

front brake lever by his elbow . no shadow of RH lever on tank = no clutch lever therefore LH foot clutch and LH hand change .
bike is resting on the kicker . right above kick spring is where clutch arm is which needs room to move forwards and backwards .
between the blue line , the rear exhaust and above the clutch arm there is a mass fairly well lit but  ....possibly brit dynamo ?    ......more I look its most likely the shifter drum housing / lid
 
Rear hub =  LH sprocket drum ??  brit equivalents ?
49 scout rear axle is straight dia 1/2-20 , any brit equivalents ?

any ideas or theory , feel free to throw it in the mix , there cant be any wrong answers

1925 to 27 the taper bearing is timken 19138 , 19283 , outer race is 14mm . this is available but no one uses them .
there are replacement BB which have the outer trimmed to suit . walkers and the guy in sweden
antiquebike .

there are 2 helical baskets , diff being the neck area where the bearing sits . shoulder if you want to call it anything I guess . .850" or .950" deep

I have original NOS bearing as a reference pre 1925 , its thrust but it can be replaced with one of the modern trimmed ones in stead.

over all width is 14mm (inline) but when reversed on it self over all width becomes 17mm = outer race facing one way and the inner facing other under thrust against each other . leaving the BB staggered ....17mm wide

the early BB or the taper need thrust washers.
the 101 replaced the bearing with 35 x 72 x 17 , right up to 1953
later bikes chief , 741 use radial bearing , HD use same BB

RH  thin bearing is used in velocette and landrover

quick reply cheers

I see AJS has 16T , Norton 11T ...
Ill check out Miller etc

its not veteran Triumph ,they are all 14 tooth generator

this is June and Jackie in the usa so its an export model . 
looking at tank logo with 4 stripes that would make it 1950 and rigid frame up to 1953 .

well spotted ... I can just see the tank rack 

2 saddle seats , both sprung I guess
fork tins have chrome ring at front gaurd level
obviously has a side stand aswell as rear stand
remembering this is marlon brando era "wild ones" movie so Id say americans were buying triumphs like crazy

Ive just been reading about the T6 thunderbird 1950 intro so yes that is a possibility too .
so ... polychromatic blue or marroon paint ...
Im searching site and net for colours at the time 

Does any one know the correct rake for an early scout frame ?

I have asked tony leenes , george yarocki , ken fox, jurgen hecker , moen , walkers , j parker , jurgen sundberg .... list goes on
it appears no one knows
I measure 23* but thats on a bent frame . I need to make a frame jig . George yarocki 101 frame diagram shows rake as 30* and down tubes 15* , the top tube is on a 5* slope .

if the neck were reset so the top tube was level then rake would be 25* and down tubes would be 20*

cheers
