I no longer use halite washers. I like to make sure that the oilseal plate sits flat and doesn't distort when screwed down.
Instead, I make up an O-ring that sits around the 62mm bore of the bearing housing. The edge of the bearing has a slightly tapered relief here as has the edge of the boss on the oil seal plate creating a nice little fillable gap for an O-ring.
I then screw down the plate and leave it for a while and then undo it and inspect the level of compression that the rubber O-ring has been subjected to. If it shows as good, then I simply make up another one and use that and all is well. If it shows as insufficient or even partial in any area, then I simply make up another o-ring using the next diameter size up of Nitrile rubber cord. (could also use Viton) No need for any messy sealants. You only need a razor blade and a dab of superglue to make up O-rings like this.
Rubber cording is generally available from most local reputable bearing suppliers in 0.5mm diameter increments and it's cheap as chips.
