Shuttle brake pad on drive pulley

[rsnik]

I bought a couple of replacement brake pads for the drive pulley on the shuttle drive of the 7013S. The glued on brake pad on the end of the cap screw falls off after a while. Also the brake pad just does not work good, it does not stop the drive pulley the way it should and causes general problems. So today I tried gluing some leather patches on the end of the cap screw instead of the brake pad. I cleaned and rough sanded the end of the cap screw with 26 grit sandpaper. I used Loctite super glue.

I glued on one patch of leather and then glued on a second layer.

I installed the leather brake pad and adjusted the shuttle drive following the step-by-step instructions in the manual. Durability remains to be seen, but the leather brake pad works so outstandingly well it is just amazing. You can change gears at even high RPMs with no gear grind.

It will probably last well as there is not much mass on the split sheave. If the super glue cracks and does not hold you might want to try contact cement which may stand shock better than super glue. I lined my pto clutch with leather back last spring and it has worked fine all summer. On my 3414s, some time in its dark past someone put together a brass brake pad on the shuttle split sheave. It works pretty well with no gear grinding in neutral and shows no signs of wear on the sheave.

Phil, that sounds like an even better set up. The brass is a softer metal so it shouldn't scour the drive pulley. It provides sufficient friction to stop the drive pulley effectively and will probably last a very long time. Whoever put it together right so it works and lasts was a good fabricator.
