Re: (ET) Mower motor bearings

[Allan V <allanhv worldnet att net>]

Steven:

Have you actually tried the Grainger puller you listed?  If so, I may
just order that one so I don't have to waste time trying to find one
that fits.  Our mower bearings have never been changed.  I want to
change them this Spring, before it's too late!

Thanks,
Allan
