A 743 is hydrostatic and doesn't have clutches.

I think he means the parking brake... mine has two free floating discs that get clamped in a brake block with brass plungers... I think.. been a while since I had it apart. If no one else puts it up for you I'll dig up my manual... but it might be a few days before I can get to it as we're pretty busy right now. It is fairly straight forward how it goes together you really don't need a manual

Yes your correct,mine are smooth as a baby’s bottom and I would have thought they would be lined like a clutch.Dave you are correct my machine doesn’t have clutches.First time in one of these so any pointers would be much appreciatedI think he means the parking brake... mine has two free floating discs that get clamped in a brake block with brass plungers...

Been a couple years or more since touched the 743 at the place I retired from but here is a link that might help a little:

You can either look by S/N or Model numbers and at least see the parts breakdowns and part numbers with quantities, often that is enough. Along with help from people here.

Just a note, when I looked at the parts picture for the brake they only show one disk, but if you check the quantity it does say "2" so kee that in mind when looking at any of the other pictures!

Ok so looking at the breakdown and I'm guessing this parking brake is using the brake block to wedge against both brake plates?

Inside the block there are two slots that the discs ride in, when the parking brake is applied there are three brass pucks/chunks/plungers... one on the inside between the two discs and one on each outside of a disc they form a sandwich.. brass-disc-brass-disc-brass these get compressed when the brake is applied
is this an older one with a threaded rod adjuster from the brake pedal? If you out of adjustment the blocks can be reset and adjustment started over hardly ever need to be replaced I cant remember how to do it with out looking but your manual should show when it comes
