You need a new presser bar, the kind with the narrow top to fit in the button cap on top. The two pieces of your presser bar should be welded together (I have seen various methods used to fit it on) and have a sort of spring action. The shorter flat piece presses against the ink sack when the longer piece is pushed down (as I'm sure you know well). I think the generic replacements work with older Montblancs, and most button fillers in general, the main thing is the get the right size.
I have had problems when replacing ink sack on one of my button fillers. I think some pens have a slight bend at the botton end of the presser bar, most don't. I'm not entirely sure, the bend might be a damage to the presser bar. At least, yours looks like it's straight and no fuzz about it. The ink sack usuall goes on, make sure the section is clean and the new rubber sack is dust free (not all are).
When you asseble the pen; the section with new ink sack is put back in place; then the presser bar is inserted from top. The filler button needs to come off.
I have to admit, I struggle a bit to see where I go wrong on my pen, I'm in doubt I have the right spring action on the presser bar when assebled, and I some how have an ink sack that comes loose on one side I think the presser bar might have damaged it some how. Get the same size in sack as the original in the pen, and cut it to the same length. My buttonf iller is being mailed to a specialst repair guy along with a twistfiller ;- )
I have ordered parts from
this site; a seller I was recommended. There is a US seller that is recommended on this forum too, there are a few models that need special parts and a good think to know about. Your pen looks like it takes the regular replacement parts.
