Vanderwell bearings work very good with nitraded surfaces. If you don't
have a nitrated surface, i.e. std crank, you can use std bearings, which
are cheaper and give you a chance to replace a bearing before the crank
is shod if a bearing runs. (provided you shut off the eninge sort of
instantly) If a vanderwell bearing runs, you need in 99% of the cases a
rigrind. Now, that doesn't mean vanderwall bearings are bad, its just
they are better for hardened cranks.

use plenty of engine oil on assembly, that works good enough.

Make sure you use a proper torque wrench and proper settings.
