Odds and sods....crankshafts.
« on: 15 Aug 2009 at 05:18 »
G'day all
I have been into the container today looking for someting and found a box of Douglas crankshafts and bits.
I imagine I have 3 DT crankshafts and some OB's.....can the learned amongst you identify what is there.
See photos.
I know the gearchange is early RA and the little leaf spring set is from a Brooks seat.
A couple of the counterweights are stamped "T 13" and "F13".....make any sense.
thanks.
Howard.

Howard,

The second set of three cranks are DT. The stampings on the counterweight are assembly match-marks. The counterweights were balanced and to a certain extent fitted to a specific crank. The T and F stand for Timing side and Flywheel side of crankshaft number 13. The crank would be stamped on the periphery of the center web, adjacent to one of the oil dippers. Often the number is faint or polished away.

The first set of three crankshafts is what I believe to be OB or OC, but I do not have any examples to compare to.

The middle one of the top three is the same as that on my OC
