Front gas tank bracket

#1

Post by heath49036 » Fri Mar 27, 2015 2:48 pm

Hello,

I have a 1940ish panhead wishbone frame that doesnt have the front gas tank bracket. I'm assuming it was ground off or something of that nature. SO, my lower tank brackets have nothing to attach to.

My question is this: Do they make a bracket that would bolt on to the front of the frame that I can attach my lower gas tank brackets to? I know I can order a replacement plate to weld on to the front of the frame. I am trying to avoid any welding on the frame if possible. I am just trying to seek out all possibilities at the moment.

Any suggestions?

Thanks!

Heath

I've never seen a clamp on Heath.You may have to fabricate your own.

I was wondering why you don't want to weld anything on your frame? It was welded on from the factory....

I know if you weld it, then you have to paint it, and we all know what that means.
If you're the fabricating kind of guy, you could certainly come up with something that bolts on and does the job.

Yeah, I really didn't want to ruin the paint job with welding. It looking like that what im up against.

Question: What year or years where the panhead frame a wishbone style frame? I see from doing research that there are 2 types of frame brackets or plates that weld on.

I'm not real sure what the difference is between the last 2. Any thoughts? I'm not sure which bracket is the right one. Like I said I have a wishbone frame.

Well, first off, you're calling it a "40ish panhead wishbone frame".

The only "40ish" panhead frames would be 1948 and 49, but wishbone frames ran until mid-1954.
First thing to do is accurately identify your frame so you get the correct bracket.
Are the front downtubes flattened for horn blocks?
Are the horn blocks present? If so, what thread pitch are the holes?
Photos would help immensely....!

The difference between the last two is the 'curvature' at the top of the bracket, vs. flat at the top.
If your frame is a '48 (no flattened downtubes), you would use the bracket that is flat on top, the second from the last photo you posted.
If your frame is a '49-early54, you would use the bracket in the last photo.

However--- it is possible that the downtubes are flattened, but filled with Bondo at some point in it's life.
So to definitively identify the frame, you should look at other features, such as the lower motor mount and the top motor mount / gas tank-seat tee mount.
If you post photos, we can positively identify it to the year, so you get the correct bracket.

The reason that the bracket is curved on the top portion, is to allow clearance for the horn. In late-'54, the trumpet horn was introduced, and in 1948, the front forks were sprung forks with the horn on the front forks.

I can see in the first photo that the top mount for the gas tank/seat tee has been cut off and a custom mount installed.
Scratch that for using it to ID the frame. I can almost see the top motor mount portion, but not quite. It looks like to me like a '48-'51 style motor mount.
The second photo doesn't help much. But the frame has several other modifications. What year is the motor, and is it original to the frame?

If you're not going to run the stock horn, you'd be okay with either lower tank mount that you showed.
There are more '49-'51 frames out there than 1948-only frames, so odds are your frame is '49-'51, based on the photo provided.
You'd be safe installing the new mount with the 'curvature' at the top portion of the mount. That way, if anyone ever wanted to install a factory horn, it would fit.
Other than that, the two mounts are identical.

Sucks that you already painted the frame. Maybe your painter can feather in over the welds when you install the mount. Good luck..!

heath,
You could cobble up a bracket using something like the aftermarket 3 piece clamps that are used for mounting footpegs etc., or you could make up something that would mount by pinching the downtubes, but . . . . . it's going to look out of place.
Your frame is begging for the correct mount to be welded in place.
Bite the bullet, weld it, and then touch up the paint :) .

Geo.

Frame downtubes look to be round, but like I said, could very will be flattened and filled in.
Top motor mount is prior to '52.
I'm not criticizing, but I see the steering head has been cut on, there is missing material below the dash mount.

The dash mount appears to have been replaced, and I'm not sure it's located properly. It looks to be too far away from the steering head.
The hole for the speedometer cable should align exactly with the hole in the backbone.
If the dash base is improperly located, it will dramatically effect the location of the new mount you want to install.
Have you done a mockup fitting of the gas tanks? You'll want to fit the new lower mount to your tanks when you install.

I also see the area fore of the seat post has been filled in. Rear axle plates are cut. Sidecar loops gone. Missing control coil tabs.
But all that stuff is common for these old frames to have suffered, no worries. It's a rider, not a restoration.

I can't identify the frame any further than prior to 1952. See my previous post, I would go with the '49-'54 style mount if it was me.
