I'm having a dickens of a time fitting up the rear pancake set of Hasslers on my '26 tudor. The edge of the emergency brake drum 'eats' into the brackets that replaced the Ford rear spring perches. Consequently I can't tighten up the rear axle nuts much at all. Were there two different designs of what we call 'pancake Hassler auxillary springs'? I ask that because these pancake Hasslers were on a small drum rear end when I bought them. Of course I know the difference between the 'beehive Hassler' and it's components and the pancake. The cast bracket that positions itself right over the large brake drum had to be ground down quite a bit so it wouldn't rub on the drum outer surface. Now the edge of the drum is eating into that bracket when the hub/drum is mounted. Anyone else have this experience? Thanks in advance

Here is an older thread about the same problem: http://www.mtfca.com/discus/messages/50893/79614.html?1232635109

Roger thanks as I just got a full set and they have been ground on also, as I had the rear arms from another set and they are not cut into. Morn George from old Mo.

The rear brackets, if for the rear pancake should fix ok..

Here is a set of Pancakes on rear of '26 chassis. Large drum. The rear brackets hang over the backing plate, but allow room for the drum to run under them.



This shot shows the Pancakes on the rear, note clearance of the drum, just enough, but not enough to run Rocky Mtn or other accessory outside brakes.



Rear hangers used with Pancake Hasslers. Fit either small or large drum axle housings.

The other thing that may be issue is if the rear wheel hubs are too worn, wallowed out taper or worn axle, that would let the wheel slip too far in and contact the brackets.

Check to be sure the rear drum doesn't go over the backing plate.

Thanks to All !! So the installation of rear pancake Hasslers caused the car to be raised about 2"? This is about the height of the special spring perch. Instead of the Ford stubby perch in the same plane as the threaded end w/ castellated nut, the Hassler perch extends up and over the emergency brake drum. Wish I had the clearances you do on your p/u, Dan. Thats about 3/8". Mine actually contacted the width of my drum until I grinded about 3/16" off the Hassler perch. Although the hub and axle taper look good, the drum does hang over the inside of the backing plate. I thought about shims on the taper but it would be insufficient to extend the hub outboard enough. Now theres a visible 5/16" drum "excess" on the inner lip until the shoes make contact. What is the advisability of grinding the drum up to that 5/16" line? I feel it'd be enough to cure the cutting into the perch. There wasn't a 'R' and 'L' like on the beehives and I installed them wrong?

Just had a thought: Were both the front AND rear springs unique to '26 and '27? What if my rear spring is earlier? Would that cause the clearance problems? I know the front spring is correct. Howdy John. Good research on the older thread Roger. I'm somehow not able to use the keyword search feature.

As for the height kick on my '26 pickup...that is because this T was original pickup, so it had the 9 leaf sedan spring. Does lift it, as there is no load in the bed, the truck rides high, put something heavy in and its down :-)

The Pancake rear bracket should fit fine, on the large drum '26-'27 backing plate on the axle housing like this. (Right side, passenger axle housing)





Here I am lifting up the swing part for the shackle. Suspect that maybe your rear spring is weak, and sags, that would perhaps make the swing bracket ride too low and possible to hit the drum?



Made this view to show what could happen with a rear wheel drum that is too far in, due to worn hub bore or axle taper.

This is what it should look like.



Now might also be the brackets do have left and right? Part numbers on swing bracket (the one with the stop part) are same #, but note this pair, the oilers are outboard, (ie facing the rear) of the car for easy oiling access.
The brass Hassler 'patent plates' read facing up and in line with the oilers as mirror image on a mated pair. Meaning both swing arm plates are the same, and in line with the oilers.

If the part is the same, at least this pair had the oilers drilled on the same side as the spring arm. Swapping them would put the oilers on the front side of the bracket.

Oh wow Dan ! Your pictures are the greatest! Many thanks ! They tell the story all right along with John Danuser's comments on the unusual wear of the rear pancake brackets he has acquired over the years. These latest rusty pictures have been most helpful. You've actually pulled the perch-replacement part away from the backing plate to illustrate how the drum rim could cut into it. Maybe I need a spacer here? The hubs and original axle taper keyways look so doggone good! And the second to last picture with the white '25' paint: That piece above the drum actually rubbed the paint off the width (1/4" strip) of the drum. I'll go to my modifications right after I shred 8-10 acres of grass/weeds at our church today. Thanks again all!!!
