Using a 30 mm socket head, unscrew the flange mounting nut…
…and we take it off (the nut is installed with thread sealant).
We remove the washer (it is installed with the convex side facing the nut).
Using a long punch made of soft metal, we strike the flange, turning it.
The flange can also be removed using a three-jaw puller (the photo was taken on a dismantled box).
We remove the flange.
Using a screwdriver, pry off the secondary shaft seal…
…we take it off.
Having lubricated the working surface of the seal with a thin layer of Litol-24 grease, we press it in with a suitable piece of pipe. We install the dismantled parts in the reverse order.
