What frame does this belong to?

[Milrite]

Got this from the brother in law who got it at a garage sale in Florida. I saw some pics from his phone, but did not have the luxury of measuring all the details. We were told it was a 26-29 single frame. Problem is, the singles have a 9 3/4" center on the motor mounts, and this frame is 10" on center. Anybody know what this frame is for?

First DL 45s, 1929s thru 31s, IIRC, used slightly-modified Singles' frames. The straight front downtube being the reason for the vertical generator and "3-cylinder Harley" appelation.

Maybe. Not all had a number there, and some were on a strip of metal so can get lost.

Thanks all! Oh well, live and learn. Fortunately I dont really need this frame, but it was cheap! So I'll throw it on the "for sale at a later date" pile! Or, maybe I'll add a 1929 45ci to the growing list of projects
BTW, I would still be interested in another frame if anybody has one! I'll be at Wauseon and would be happy to pick it up there If not, how about a 1929 45?
There is a CVMG swap meet here this weekend in Paris, Ontario, 10 miles from home, I'd be even happier to pick it up there!!!!

Thanks Ken;
I have found that the 26-29 frame is not readily available (least wise not since I have been looking for one in the last 8 months or so), which is why I jumped on this one, as it was in a little better shape than my other gearbox frame. I have seen a few modified frames, basically with the tranny shoe modified to fit a jack shaft, but that said, they were all pretty crooked and had pretty high sticker prices. My "c" motor obviously doesn't fit either, but I have another frame plus the repop.... So when time permits, I can start fitting it all up and assemble my piles of parts! Except my new tanks that I ordered 6 or 7 months ago. But alas, I also have two sets of tanks. Same story, the second set were a little better than the first. From Paul actually, who makes the nice shcebler carb covers.....

27-28 and maybe 29, brake cross shaft tube,right side long,left side short,no casting numbers in trans saddle,28-29 left rear frame has brake stay brazed or welded on tube, 29 -34,start seeing changes to a wider back end,frame used for singles and 45 twins

Yes Ken, 1926 is one-year only with short crossover tube, but there are frames both with and without the raised 26-casting. I would identify the frame as 1927-28. The 1929-30 21 Single frame has a full pan under the engine. I have not actually tried, but I have thought all the 21, 30.50 ahd D45 motors should crossfit all 1926-31 small Harley frames.

Hi Fiskis;
I thought the same about the late 20's frames for singles and 45's. But the tape shows 10" centers on the motor mounts, my B and C motors are both 9.75" on center.

[Fiskis]

Do you mean that the distance between the motormounts differ from your other frames. That seems odd to me. The R- and the W-series frames have different configuration of the motor mounts, but I believe that all A, B, C and D frames crossfit with all these motors. I'm now in Spain but I can check this out when I'm back as I have all these components at hand.

Thats correct.

Hi,

Checked out that the B, c and D motor cases fit in the Single and early 45 frames. I think that the frame you have has been extended by accident or as a try to fit a W series later 45 motor.

Thanks Fiskis. I can see no sign of alteration, the mounting holes are not elongated in any fashion. I may just unalter and use it as it is. Throw the "C" motor in, the gearbox, stud the tires and head for the ice!

It must be an original road model frame, not a race "S" frame. It is hard to see on your pics but maybe there is a slight outward distorsion on the front upgoing tube under the front motor mount. That could move the holes 1/4" forward. It should not be difficult to correct the misfit.
