Thanks for the starter help guys!

>$35 for Brushes... ouch! Still cheaper than a starter.

I had considered trying to find the brushes from other
sources for less, but had some second thoughts about it.
There are actually 4 brushes in there; 2 are attached to
a lead which goes to the solenoid ($11), and the other
2 are soldered to the brush holder (24).  The brushes in
there now are definitely worn and need replacement.  I think
I could probably find generic brushes for less, but then
I'd have to have someone do all the soldering work (I
don't think my 85W Weller can handle leads that thick);
the cost of this will probably save me, what, $10?  So I
figure I'd just save myself the hassle of running around.
And besides, these things will fit the first time...(I'm

Thanks; that's what I needed to hear.  I had thought to use
some steel wool until I thought again; your note clicked in
my head to use some crocus cloth or a scotchbrite pad.

I had thought there was some lube for the end bushing, but a closer
look tells me there's a sealed bearing in there with some sort of
thrust washer underneath.  I guess I'll have to clean it up as
best as I can (I figure solvent is a no-no here?)

I'm over at the Jones Farm campus; close enough!  I'll drop
by there after work.

Thanks again for the help guys!
