There is a trick with the aluminum decorative molding that

fits into the gasket that took me many years to finally figure

out. Be very careful when you remove it to avoid bending

it any more than necessary. Like most thin soft aluminum,

it work-hardens rapidly so it is much easier to not bend it

in the first place than to get a bent item looking new again.

An appropriate rubber lube is a great help in both getting

the molding out and putting it on the new seal/gasket.

The trick is to block the lip of the seal up enough that

the aluminum molding will slip into it easily. You do this

with something flexible and round, such as the factory-

recommended 4mm round leather thong. (??)

I tried a lot of things that were a lot stronger than

a 4mm thong, but not that big, and it was absolutely

no help; plainly impossible. Then after about the

50th reading of the manual I began to wonder why

they emphasized that it must be 4mm in diameter.

I found some vinyl-insulated stranded wire whose

outer diameter was about 5/32" (3.97 mm, close

enough) and crammed it into the slot with some

rubber lube and was impressed how high the

offending lip stuck up. It was then pretty easy to get

the flat part of the aluminum molding under it and pull

the wire out as I went. It only took 2 more tries to get

it right.
