Well, I am engineer, not a VCR technician, but I have replaced heads
on VCR's before and it is pretty much a bolt-in replacement.  Well, you do
have to do some soldering in addition to the bolting.  On my Samsung, you
just pop off the dust cover over the slip rings, unsolder the wires connected
to the slip rings, remove the retaining ring, and ease the head drum up and
off the shaft.  To install the new one, just reverse the above.  I didn't
need to change any alignment stuff afterward and neither have other people
I know who did it.  No special tools or test equipt. needed, except you
may want to splurge $5.00 on a pair of retaining ring pliers.
