    Default 2 more JD's for the road

    I have 2 JD projects to do this summer.
    A 1926 and a 1929.
    My current plan is to have both these bikes as riders by the end of the year.
    I don't have any plans to restore them yet. I am looking out for a sidecar or, preferably, a package truck.
    Depending on what I can find, one of these bikes might get restored.
    I have collected a lot of the OEM parts I need to replace the repo and missing parts, but am still short of some stuff. mainly lights and horns.
    The 1929 apparently has a fully reconditioned motor that has never been started, however I suspect it is a 61" motor in JD cases.

    All the usual work to do, straighten bent parts. replace incorrect parts, chase threads etc.
    I had better do some spring cleaning around the house first, as I won't do it once I start on the bikes.
    Cheers,
    Mick

    I envy you, Mick. You have 2 great projects there, and there is a lot of enthusiasm for later J model Harleys in our hobby. Electrical parts are the most difficult to find, and often the most expensive, as I'm sure you know. I have a 1919 Henderson that I spent many years tracking down the electrical parts for. The generator was the toughest part I have ever had to find and I had to buy a whole motor to get that generator. Like Mike, I look forward to seeing your progress on those beautiful motorcycles.

    Thanks all, I am looking forward to riding these some day.
    I also have another 29 JD project in a box, just parts.
    Once I have these two bikes running, I may sell them and build another 29. I have another 3 bikes I need to sell, running out of room.
    Spent the morning going through all my parts, looking to find what I don't have. Apart from lights, I think I am in good shape.
    Cheers,
    Mick

    Mick, it's great to see you JD's on their lifts! Looking forward to seeing them revived back to life!

    Got a start on the 29.
    First project was find out why the kick starter doesn't turn over the motor. Pulled the clutch and found no key in the mainshaft, that is an easy fix.
    Felt a bit of play in the main shaft and high gear. Pulled the clutch hub and found water marks and some rust on the mainshaft. High gear also has a bit of play, but I haven't looked in there yet. Afraid to find what I expect. Not so an easy fix.

    Also noticed that the cases have a mixture of bolts and studs holding them together.
    This motor has a 61" engine in 74" cases. I will change the bolts out when I change the cases for a 61" set.

    Next major project is to change out the magneto for a generator/ distributer system. No point in having a pair of big headlights on a 29 if you cannot use them.

    Making progress.
    Cam cover and gears have been changed out for generator drive parts.

    Found a couple of items that needed addressing.
    The oil pump drive was an early model, 22 and earlier. Had a later one in stock, so no problems.

    I pulled the rockers and pushrods as part of the cam cover change. has new late model pushrods with big ball ends. One rocker had a big ball socket and one rocker had a small ball end, (pre 28?). Found a good late rocker, so now I have a set of 28 rockers on the 29 motor. Will need to keep an eye out for a set of 29 rockers with the bigger bushes.

    Stripped down the generator to clean/repair anything needed.
    Armature was good, just needed the commutator turned and undercut. bearings and brushes will be replaced.
    Pulled the field coils and they seem like they have an intermittent connection problem, so replaced those.
    Next step is to reassemble the generator with the new parts.

    I broke my 29 timer by being an idiot, so I may have to run a distributor for a while until I can find another timer.

    Started looking at control cables and couldn't figure out why the throttle lever was in the wrong place. Turns out it was correct, it was the carby that wasn't correct. A M1 was fitted, not the correct Schleber. I had a restored DLX 66 so I installed that with a genuine air cleaner setup. Probably should use a DLX 45 for better throttle response, but I don't have one.
    Now the throttle cable meets up with the carb and oiler control cable.

    Hopefully get the motor closed up soon, then on to the transmission and wiring.

    DLX 66 installed

    This may be a stupid question but how do you tighten up the left hand nut on the end of the generator armature?
