Getting rust off Crank

i just bought a motor that has been rebuilt and sitting on a pallet under plastic for 2years, everything looks great has been oiled and rotated regularly, the only rust i visablty see is on the front of the crank where the crank damper goes, how can i get this rust off, i was thinking about taking some 600 grit and lightly sanding with some wd40 oil?

steel wool pad

do i put some oil on it and use the triple 000fine?

I'd use solvent & not sure of the grit but the finer the better as long as it'll cut what your trying to remove (the rust in this case)

i will try this tommorrow,

thanks

You don't need to worry about using such fine paper. Even, I donnooo, 120g should be fine. You don't need to get it absolutely "chrome," just clean off the rust so you can get the damper on, and there's no debri that'll make it into the pan

Have you tried CLR or Naval Jelly? They work really well without the concern for removing material. Let it sit, then fine steel wool it to clean up the surface.

grab a steel wool pad w the soap in it from your kitchen & dip it in solvent & it'll be rust free in no time

or some crocus cloth. This is an area that isn't real particular. Just so that the damper slides on slightly snug, it is not a press fit.
