This
is how I replace the oil seal ring which should keep the
flywheel dry of oil. I re-used an old toothbelt gearwheel
from GM and adapted it on a lathe to take up the central
M18 bolt, taking care of having parallel surfaces which
will later press against the oil seal. Pressing the new
oil seal into place is a piece of cake now. Take care to
rub grease/molykote on it and a few drops of oil. The
first revolutions will be without any oil from the
crankcase so this first lubrication prevents ruining the
seal. |
