I got the transmission section entered, taking pictures of the parts I have in my stash. The only change on
the home page is that big table now has a blue link to "transmission". That link goes
here.
I made thumbnails of all the parts for the first table. You can drill down to individual parts or to higher sections. The table below the first one has part numbers. The tranny level only has the numbers for the shifter shaft and bearing since they "report" to the transmission sub-assembly. To see the part numbers for the sub-sub-assemblies, you have to look at the second chart on pages for
Countershaft,
Mainshaft, and
Trap door. The Mainshaft asy has its own sub-sub-subassembly, the
Clutch gear, and the Trap door asy has another sub-sub-subassembly, the
Shifter.
The look and arrangement of all this is still pretty tentative. All the part number tables have the pop-up image of the bikes on the left, which is a carryover from the top-level table software that builds these tables. I would like to get it so that hovering over a part number will pop up an image of the part, but that is a long way off. First thing is to get all the major assemblies represented, with at least a few model year's parts, and then I can fill in the different year part pictures as I find them. I expect to have an entire trove of pictures when I take apart my 1952 K-model.
Thanks to JerrryR for noting just how crazy some of the early bikes are. He pointed out to me there are dozens of changes to the early frames that are not noted by any part number. I have witnessed this in the transmission section, where sometimes I see parts that have no service number, like the shifter pawl spring retainer, until about 1970, when it gets a -70 part number, but we can see for a fact that part was made and used all the way back to 1952. I assume that they just considered the retainer plate part of the pawl holder assembly, and when AMF bought them, they were under pressure to "release new parts" so they created a new number for this. I noted elsewhere on the forum how the factory also had a -52 center stand, but they didn't appear until the 1971 parts book.
JerrryR said he is up to revision 14 on similar projects and I am sure I will have many changes and improvements as time goes on. I just want to get the structure of the BOM fleshed out for now. I tackled the transmission since there were not a lot of changes over the years. I figure next to do flywheels, since there were so few changes there. I do have a KH flywheel in my parts stash, so I have that covered, and I also have both pre-1976 and post-1976 flywheel assemblies. I figure there are 4 basic types, early K, KH long stroke, the early pinion shaft up to 1976 and the cheap pinion shaft 1977 and later.
I am re-arranging my house to make a photo and video studio in the living room. Once that is done I should be adding to the sections of BOM and hopefully create a reference that we all can use to figure out what is what. JerryR also recommended I add some disclaimers to show that none of this is definitive, the whole community is figuring out what was going on back then. I will do this next time I do an update to the home page. One of the biggest shortcomings of all these tables is I had to round off when the factory did changes in the middle of the year. The parts book will say E79 or L56, or in some cases, give a serial number when the change happened. It would just be too unwieldy to represent this, so I have to figure out how to add an asterisk to show that. I did try to explain these running changes in the detailed part page, so for instance
the clutch gear page points out as much information as I could get out of the parts book.
