I agree with wz abouve. Possibly a typo? 57-59 should be center screw with windowpane instructions

WZ, you are correct. I mis-copied from my notes, and now have corrected the posting above, as well as the web page I'm working on. I'm using your photo on the webpage.

Here's another conundrum! Palmer says the 1948 -to- early-1955 instruction tag is mounted so you can read the tag from the street side, and the photo in his book (below) shows it that way. My '54 is that way. Jerry - your photo shows it readable from the rider's side!

Another minor point is that Palmer says "steel round-head rivets are used to attach the plate". The rivets on my cover are flat.

OK guys, dig out your air cleaners. Which way is the tag mounted? What kind of rivets?

Both my former '56 KHK and my current '57 Sportster have the air cleaner as pictured by wz507. My '59 XLCH (#23XX) has the cover with no window pane and the larger lettering; I don't think it has been replaced but can't be 100% sure. Another detail on the screw-mounted covers: '56 has a chrome-plated slot-head
mounting screw; '57 and up uses a Phillips-head chrome screw. My KHK still had the slot-head screw in place but poor condition; this was a very shallow slot and if your screwdriver wasn't an exact fit, you were going to mess it up. I had one of these NOS years ago and have only seen a couple of used ones; I assume Big Twins used the same. This shows up nicely in both the '56 Enthusiast new-model issue and in the parts book, the list in back just calls it a "countersunk head screw". The '57 Museum bike,parts book, and period road tests plainly show the Phillips head, parts book just calls it "air cleaner cover screw" and it's not even listed in the back. In '59 it returns to the back fastener list as "oval head screw". I don't find it called out as "Phillips oval head" until the '63 parts book, all parts lists show it as "2402C". Always open to comments or corrections; this stuff can get very confusing, and with a severe shortage of original bikes
we may never figure out all the details.

Your bike was made around April of 1959, way too early to be an end-of-year supply problem. We've got a few 1959's in the crowd - can anyone shed some light on this?

I saw the slotted screw in the parts book, but figured it was just an illustration problem. But here's the Sept. 1955 Enthusiast (1956 Announcement issue) photo - definitely slotted. The Sept 56 Enthusiast (1956 Announcement issue appears to show the Phillips head screw, as does the 1957 parts book.

Harley seems to have changed a lot of screws from Slot to Phillips during the 1950s. The rear fender support screws and tappet block screws come to mind, but I can't remember when they changed.

Jerry,

Compare your 1960-1965 to the one on this page-in-progress: http://www.harleykmodel.com/technical/a ... index.html

Your letters, and the spacing between lines, appear to be much larger than mine. Looks like they changed between production runs. Can you measure the height of the letters? I'll measure mine.

The one on the web page is from my 1962 XLCH, but I can't swear that it's original.
