1950-1953 Midstream the 1950 Chief serial numbers changed from CEJ to just C on BOTH engines and frames, upsetting the rules as shown in the 1932-1950 table. Early 50's Chiefs were CEJ, late '50 and' 51 Chiefs were just 'C', and all '52 and '53 Chiefs were 'CS' . When this change happened all vertical twins also had frame numbers matching the engine exactly too. Examples : Eng# BEJ911, Frame # 250911 is 1950 Warrior. Eng# B1003, Frame # B1003 is 1951 Warrior. | |||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||
MP=Motoplane (in Jr.Scout frame) |
1932-1950 Frame Numbers introduced late 1930 early 1931 See note 9. Example:we have an unknown motor (or cycle) that's stamped CDF 6403 and a spare frame stamped 441 1089 <work in reverse, i.e. numerals to letters using table or your fingers!> 1st letter is C, this is the series, all Chiefs are 3, Fours are 4 etc (see table left) | |||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||

1926-1931 Indian lost the plot for a few years between 1925 and 1933 with their numbering, possibly exacerbated by the 101 series 'no new model years', the Ace acquisition and how to incorporate frame numbers in 1930/31 which I will ignore in this scenario. Examples: AH1088 is a 1926 Big Chief, 74ci, serial 1088 (similarly, AZ1088 would be 1926 61ci) BGP1055 is a 1927 Scout, 45ci, serial 1055 (similarly, BG1055 would be 1927 Scout 37ci) EA779 is a 1930 Four, serial 779 (similarly, BL779 would be 1926 Prince) | |||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||
Model/hp(Hendee/Indian) 1= 2 hp single 2 = 5hp twin or 2 hp single 3 = 4hp twin or 2 hp twin, or 21ci Prince single 4 = 4hp single or 30.5ci Pplus 5 = 7hp twin or Scout 37" 7 7hp twin or 61ci PowerPlus 8 = 8hp twin or Chief 61ci 9 = Chief 74ci = or 72ci Powerplus Years Example A=1909 B=1910 C=1911 D=1912 E=1913 Ex.3 F=1914 G=1915 H=1916 J=1917 K=1918 M=1919 Ex.2 R=1920 S=1921 T=1922 V=1923 X=1924 Ex.1 Y=1925 (I, L, N-Q, U & W not used.) also see note 12 for ?Pxxx models (where ?=R,S,T or V) |
1909-1925 hang on it gets a little tougher now!.
Its a little like an odometer that clocks over in units, tens, hundreds and thousands and tens of thousands. You may find it easier to pay attention to the year first, then look at table and determine the models for that year, see Example 2. Example 1 - 51X107 Take the engine number 51X107 which breaks down to: 5 is Scout 37", (because of X) then because the second number is not zero (as it would be if serial < 1000) we add it ( 1000) to the serial 107 making it 1,107, The X is the year 1924. So it is a 1924 Scout with a engine serial of 1107... eg. a serial of 54X155 would be the same model and yr with a serial of 4,155. similarly, a serial of 67X157 would be the same model and yr with a serial of 17,157. Example 2 - 72M911 Example 3 - 86E630 <please see note 8> | |||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||
1902 101-243 1903 244-620 1904 621-1167 1905 1168-2349 1906 2350-4048 |
1902-1908 There was no commercial sales in 1901 but numbering began 1902 starting at #101 and remaining in sequence to #4048 until 1906. This gives us an insight into production numbers. From this point till 1909 as the database illustrates, its anyone's guess what someone was dreaming up! | |||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||
Engine number suffixes
"A letter may be stamped after the engine number (but off to right of boss itself, i.e. on crankcase): these letters are:- A is for aluminum pistons which were optional over std cast iron pistons in scout 45"in 1928 see note 5 B is for Battery ignition (distributor). (post 1933, see below note) ...BUT - B was used (briefly) to denote blackout lighting fitted by the factory on mil. cycles during WWII. see note 6 - B also designated aluminum piston and/or special clearances for performance and/or sustained speeds on pre '28". - B also designated aluminum piston, chief carb (DLX81?), chief valve springs and chief inlet nipples/manifold used on special factory 101 Scouts. BM is for Bonneville Motor. BY is for Battery (Distributor) ignition on 'Y' motors, i.e.. Y manifolds, trench heads (Ricardo) etc - mostly mid 30's models. M is for Magneto ignition. MY is for Magneto ignition on 'Y' motors, - rare, mostly mid thirties models. Frame number locations (also see note 9) '31 and up rigid frames are on a boss just below the left rear axle slot, '40 spring frames are on the left rear shock casting above the axle slot, '41 through '51 are on the lower left shock mounting ring, '52 through '53 are on the front face of the right front footboard casting mount. '49-'52 VT's (Vertical Twins), i.e Scouts, Warriors/ TT's and Arrows, have the frame serial on the front forks. '34-'42 DT's (Dispatch Tows), i.e 3 wheel Sports Scouts have the frame # under the seat on the frame casting.

Extended Notes and Contributions. 1.
Introduction. This database is by no means perfect, but as close as we can collectively get it to-date. Consternation lies mainly between the dates of March 15th, 1928 and 1st November 1st, 1931, the latter being when frame numbers were introduced and
numbering and model numbers were somewhat rationalized.
Evidence of a possible serial number G3433 on a 30/31 101 here.
The first Fours rolling out of the Wigwam were nothing more than Aces, but immediately were made a finer machine for riding conditions, which had changed in the years since the Ace was first made. The forks were strengthened and brakes improved. The engine received pressure feed lubrication, and included upgrades in cylinders, pistons, tappets and valve gear, all to improve gas flow. In July of 1928, Indian announced the first true Indian Four, the Series 401 as the company then stated they would make only running changes and would not recognize model years. The 401 was designed to have the appearance of the popular Series 101 Scout. The new Four received a 101 fork with an additional leaf spring to handle the extra weight and the streamlined gas tank and fenders of the Scout. The frame was still Ace with a single front down tube. A year later, the Series 402 was announced. The frame was now a double front down tube giving the appearance similar to other Indians. The engine reaped most of the benefits. It gained a five main bearing crank and babbitt was bonded to the case and rod journals instead of using removable bearing inserts.
Significant changes were introduced for the 1931 model year but the machine was still referred to as the 402. Effective from mid-year,
the crankcases were revised with a central drain plug and additional ribbing on the bottom case. Newer special alloy pistons reduced clearances, producing less noise. The frame gained the more notable
improvements. DuCo lacquer replaced enamel, and heavier cadmium plated spokes were used in the wheels. Finally, an effective brake was used in rear wheel. An Autolite generator replaced the smaller
Splitdorf unit. The ineffective bullet headlight was replaced by a John Brown Motolamp and centrally mounted on new handlebars with a revised shape and a crossbar. I had a 1951 (FEA106), a friend has FEA103 & FEA104. A FEA105 is overseas and
is a two wheeler, I have pics. You cant say it was never made because if you wanted special orders they would make it. 103 & were NYCFD (fire
dept) bikes. I sold mine 20 years ago, my friend still has his. 16. "Starting with Motor no. EA580, machines were equipped with all steel clutch, wide transmission gears, single keyway trans shaft |
