1952 Panhead frame mounts

#1

Post by doug_heisel » Tue Jun 16, 2009 7:17 pm

As I've said my bike is a 52 FL I've had my bike mostly mocked up. However there are many other holes and tabs that I cant figure out what originally went there. Ive figured out how the tanks, fender, engine, dash, seat, oil filter floor boards, brake, clutch and tool box mount. That still leaves alot of holes and tabs. Could someone post a road map to my frame? :? For instance there is a tab that sticks out from the front of my frame that points back toward the motor. It looks like it might be important. :)

The brackets welded onto the down tubes are for the horn mount, the one between the down tubes is for the engine guards to mount with those little spool spacers, the big holes on the rear axel plates are for the rear crash bar mount, and also I believe side car mounts and center stand and muffler bracket on the right side and the small tab under the seat is for the ground cable....Mike

Oh yeah, That rusty area behind the tranny has two bolt holes for mounting the adjuster bracket.

The tab on the left front down tube is for the timer advance cable. A small clip holds it there. I think the 52 horn mounts are supposed to be rounded off not squared.

The holes behind the tranny are for a bracket that wraps around the adjuster stud, that you see in the picture. It allows for adjustment of transmission for primary chain adjustment.

A bracket that allows you to adjust your tranny? does any one know where I can buy the bracket. cause its not in any of the boxes I got with the bike. It sounds like its pretty important. Or is there another way to properly adjust the tranny?

You can adjust it with out the bracket by prying back on the tranny and then tightening the mounting stud nuts. The bracket makes it easier. The bracket you need is the lower one shown under transmission adjusting kit on this link to the custom chrome site. http://www.customchrome.net/icatalog/full.aspx?Page=709

Thanks I was wondering if you couldn't tighten it like you would an old altenator. Thanks for the site I will order the part any way It belongs there and a tight primary chain is definatly a good thing.
I warned you guys I'm full of stupid questions. :D

Starting in 1952 MoCo started stamping the top motor mount bracket on the right side (gear case side). Consists of a number followed by a letter. The number is the year, the letter represents the month (A=Jan...)

And that hole you have on the right side of the neck above your key lock is someone's homemade drilled out hole. Not factory.

Thanks everyone thats alot of help! I started digging through the remaining box of parts and found half of my tranny adjustiing bracket. I dug out a piece of angle iron the right thickness. Cut out a piece the right size. drilled it shaped it and now I have a bracket. It works great. Thanks.

What do you mean "half of your tranny adjusting bracket"? It is only one piece! Just a sort of flat strap with a U bend on one end for the adjuster bolt to lay in. And remember that your primary chain should not be "tight" or you will be replacing a variety of ruined parts.

The flat strap with the "U" shaped end bolts right on the tranny bracket, holding the special adjuster bolt in the "U". No extra bracket is needed. Mike
