I'm looking for hardened and ground washers for the cylinder head nuts and the
rocker stud nuts. Been reading Carroll Smith's book on fasteners and he makes
sense to use these washers in this application, especially the cylinder head
which has spot faced locations for the washers. I have washer from Moss but
they all are "crushed" and obviously not very hard. (Checked with a file and
they are just plain washers as far as I can tell, the right size though,
almost.) On the rocker studs, I had used double Gr. 8 washers and they still
got "dished" into the rocker pedestal holes. I'm wondering if some of the
rocker pedestal stud breakage is from not having a good hardened and ground
washer under the nut and the nut loosing it's tension and/or bending causing
the breakage that has been reported. This has probably been discussed and
maybe everyone is already using these type of washers. I'm still pretty new
at this and still have a lot to learn.
Would appreciate anyone who has a source for these type of washers in the size
needed. Did the usual Google thing and haven't come up with a supplier who
would sell just 20 or so.
Thanks,
Tim
