If the arm goes too far forward, it could release the detent lock pin.

That stop was first fitted to transmissions in 1926, and is seen in the 1926 parts book as pn 2429-26.
Additionally, first seen in the 1928 parts book as a new part number, a "kit" of sorts consisting of the plunger screw, locating pin, spring for the locating pin and included the sliding stop with it's cover.
This 2239-27 "kit" did not include the locating plunger nor the plunger spring nor the 2429-26 stop. The 28 book calls for this "kit" to be fitted to 26-28 twins and likely first appeared on the assembly line as the late-1927 twins were being built.Last edited by Steve Swan; 03-04-2021, 09:53 AM.

Ah, thank you Steve! I've had a couple of those clutch arms with no interlock feature, so that's where they come from. With that part number, does that mean the V-bracket/stop was only used in 1926, because it would be more or less redundant in '27?

The V shaped bracket is a clutch arm stop. Pt no 2429-26. The 26& 27 tranny didn't have any type of clutch quadrant as later models. There fore the clutch arm could travel too far forward and possibly hit the clutch bearing fork internally against the mainshaft. This bracket was installed to limit the forward clutch arm travel.

Thanks Steve and we all like one-year-only parts, but what does the V shaped bracket do?

Originally posted by exeric View PostLong overdue, Steve, and thanks to you, Bruce, Mark, Tom, Terry, Pete, Johan, Jan for expert information. The entire F, J, JD (and the rest of that alphabet series) are so individual, and year particular that it makes for a colossal undertaking. The whole J series are my personal favorite Harley-Davidsons because of their yearly individuality, but also because the J era made Harley-Davidson the iconic brand that it is today. I know that could be debated ad infinitum, but I believe the J series was made when the founders were in their stride, and they honestly tried to use the best materials (for the time) and the best engineering in that post pioneer era. I think the J series is what made Harley-Davidson a household phrase for motorcycles. Please keep us posted on when this publication comes available. . . . Again, Thank You.
Thank you Steve for taking on this project. I will buy one of your books when they are finished and i know at least two other solid buyers who will also buy them!

Help with a Harley 1915-29 Pocket Valve book please
Dear All, I need help with a forthcoming book on these bikes.
Bruce Linsday has asked me to write an identification and restoration guide to the 1915-29 pocket valve Harleys and I'm perhaps a third through it. We are still waiting for Mark Masa's definitive workshop manual, so this is an interim effort of perhaps 150 pages aimed to be out in the middle of this year. You will know that AMCA members have written detailed 1929-64 Harley manuals, but nothing earlier, and the experts are getting older while the judging statistics show the average member is interested in later bikes. There's no money in it, but the time is right to get that knowledge out in print.
The layout is spiral bound landscape pages to allow full page bike pictures. We have a printer and an ISBN. The first third of the book is an overview of the business environment, production numbers and models, engine number examples and summarised technical changes. Then two full page photos per year of good restored or unrestored bikes, with more technical detail of changes from the sales brochures etc. Then each major assembly such as forks, gearboxes, engines is treated in more detail, with pictures of key items and restoration tips. I've Emailed Mark Masa and Jon Neuman for assistance, and have had great input from Tom Feeser, Terry Marsh, Bruce Linsday, Pete Reeves, and Dutch members Johan Wijers and .Jan van der Werff who all have enviable collections and technical knowledge. Bill Wood has assisted with Cannonball Run photos and AMCA calendar pictures.
For the main central section I'm looking for two full page photos per model year, plus four on the back cover and two on the front - presumably 1915 and 1929 - meaning I'm looking for pictures of 36 restored and unrestored machines that might qualify for our Winners Circle. If you think your machine qualifies, and you'd like to see it in print, please contact me. All contributions will be credited. Likewise for any pictures of tanks, toolboxes, chainguards, forks, engine numbers, generators, gearboxes, headlamps, mudguards, striping details etc that illustrate particular changes, or restoration tips for others to benefit from.
If you would like to contribute to any particular year discussion, or major assembly description, please let me know and I'll Email you a draft section for comment. Likewise, if you know of other people or other bikes, please contact the owners and see if they would like to be involved.
Best regards, Steve Slocombe, vlheaven@aol.comTags: None
