Turning Brake Collection & Differences

["D"- Man 827]

I assembled some of my turning brake parts that I have collected.  Some parts have been restored while others have not.  This is only part of my collection as I also have turning brakes on my D-180, and I failed to include a disc in this display.
Most are Wheel Horse' however, some are from a Cub Cadet.  All parts from Wheel Horse are comprised of parts from an 18 Automatic {Turning Brakes model # 8-1901} or "D"-Series.  
Even Though there are some differences in parts most could be interchanged with little or no modification.  
The Secondary Bracket from an 18 Automatic was wider and beefier, than those made for subsequent models, as well as, those used on the Cub Cadets. 
Notice the two on the right {above} have a thicker metal than the one on the left.  You may also notice that the two from the 18 Auto did not have the little flat bar {or two} welded onto the bottom.
The 4 shoulder bolts on the 18 Auto were 3/4" longer than those on the latter systems. {middle and lower right}

The long rod and the short rod remained the same, but the medium rod was assembled with a footrest stop welded to the end, on the latter models.  This is a picture of the early style rods.

The pedal pivot assembly on the latter models had a cut-away portion {to retain grease} at the point where the pedal attaches.  {Middle left}




The pedals on the 18 Automatics had only one hole each; whereas, those on the latter models had two holes each.

The Brace Assembly on the latter models had an extra support bar welded on to attach under the footrest, those on the 18 Automatics did not have this bar.  
The rubber material for the pads were different as well, and followed the same material as used on the footrest.  
The latter brake mounting plates had a piece of angle welded to the upper side, the earlier brake mounting plates did not have this angle.

The early shafts had only a 1/4" diameter pin to secure the arm, while the latter models used a 5/16" roll-pin.  This hole size was the same for the holes in the arms, respectively.
 The two shaft bearings were wider on the 18 Automatics than on the later models.  Part #'s for the discs are different; however I do not know why.  
The 18 Automatic parts list only lists one size for the Spring Anchor Plates, while the latter models list two additional thicknesses in the parts list, presumably to be used on an as needed basis dependent on the need.
The plate assembly {with the pad} has a different part # between the early and later models, but here again I do not know what the difference might be.

I will "STOP" right here as I have already said more than I know about these, Mark.

Wow, I don't know much about the 'D's but it took some time to lay this out so neatly!  Very nice

Thanks Karl, it also took some time to collect all these parts.  Some are N.O.S. {repainted,}  some were free and others were quiet expensive.

Resurrecting this post....need some help and advise if possible.  Was there 2 different version of the turning brake kits?  Believe the center bar for left side is what isn't in the picture which I believe I have.  But, there is a plate in the middle of said bar in one picture I've found but another picture and kit looks different

Have seen 3 different kit numbers

8-1900 - Service bulletin

8-1901 - Have manual

8-1903 - Have manual

There was likely a 8-1902 but have not seen anything on it.

 

Do a search of the files for "Brakes disc" in quotation marks. 6 results will show up with some duplicated to get them with the appropriate model years.
