I've got the following identification on my rear axles:
Right: BTA501S MOWOG BH ONES EN17
2A7242
The first line is all cast into the axle; the 2A7242 is stamped (irregular in alignment; handstamped?). The 'ONES' is cast in smaller letters and not real clear.
Left: 2A70 85 EN17C MOWOG ONES
All cast; no stamped alphanumberic; the 'ONES' is also cast in smaller letters but pretty clear.
She's a 1960 model, and has never had anything other than the 948 cc engine. I replaced the right axle (unknown donor model) sometime in the 70s/maybe 80s when the splined end twisted off, using a 'puller' 'fabricated' from a piece of 1/2" plywood.
According to Horler's "Original Sprite & Midget", the Sprite Mk IV and Midget Mk III got stronger half shafts. "The steel wheel shafts could be recognised by the new part number BTA 806 in raised letters on the end face. As the new shaft was interchangeable with the earlier type, it is now quite common to find one fittted to an earlier axle."
He doesn't indicate the chassis number at which the axle changed occurred (or my skim reading missed it); however,he also shows under Special Tuning that "axle shaft, heavy duty, disc wheels only, C-BTA 1226; axle shaft, heavy dty, wire wheels only, C-BTA 939", and that production of these models began Oct. 1966 and ended Oct. 1974.
Anyone got suggestions as to what I do have? I'm assuming I DON'T have the 'stronger half shafts."
