Topic: Rocky Tune-up Experience.... (6 msgs / 283 lines)
1) From: Bob Holland
Since there has been some talk of the venerable Rancilio Rocky grinder
lately, I thought I would share my "tune-up story". I purchased Rocky about
4 years ago in a group buy from this list. I grind about 3/4 lbs a week for
both espresso and drip. I have heard from the those much more knowledgeable
than I, that the burrs need to be changed by about 100lbs ground; sooner if
you grind the rocks, glass, metal, etc that can inhabit your homeroast from
3rd world origins! So I ordered the replacement burrs and went to work.
Top burr removal no problem, 3 screws and its out. When you feel the old
burrs compared to the new ones, it becomes obvious what dull burrs do to the
bean. Removing the top burr carrier is simple and gets done regularly to
clean beyond vacuuming. Note here: the burr "carrier" is heavy brass, while
the collar it screws into is aluminum (soft).
When I tried to remove the bottom burr I found it would not budge. A quick
check with Mike McKoffee and I was assured the screws do come out and the
lower burr will pop out. After removing the screws (obviously torqued in by
Guido in Italy), I still could not budge the burr loose. Instructions say
the burr should be removable without pulling the lower brass carrier. I
resorted to a gear puller to remove that assembly. Finally got the burr
loose from the carrier by smacking it flat against the concrete floor. I
found the burr was actually "pressed" into the carrier making it impossible
to remove without significant force. I had to grind a small amount from the
new burrs to get them to fit flat.
So after getting the burrs all seated I find I am unable to screw the top
burr carrier more that 4 turns into the collar. Ultimately, after much
frustration, I take Rocky to a certified Rancilio repair location. I am told
and shown the upper burr carrier is damaged. New burr carrier, problem
solved! WARNING FROM RANCILILO: They are no longer selling the upper burr
carrier as a part! If you damage it, RANCILILO will only sell you a NEW
machine! I didn't question that bit of info, but I will certainly treat that
new burr carrier like gold!
*new burrs - $42
*new carrier-$65
Great espresso-PRICELESS!!

Bob,
Thank you for the information!  This confirms my affinity to the Mazzer.   I
can't believe Rancilio would be that customer ignorant!  At least Solis has
gotten with the program and you can get replacement burrs for both top and
bottom with the carrier if needed.  I may have to retrieve my Solis from my
mother-in-law and put it through the paces, do a replacement and keep good
records of wear and tear.  I may have to drop my love affair with the Rocky
as the best value out there.  Everyone knows burrs need to be replaced or
the whole machine.

Bob has an obstinate Rocky! Have replaced my Rocky's burrs 3 (or 4) times
and never had to pull the whole lower carrier to get the lower burr out.
Does usually take some careful prying to get it out, but apparently my lower
carrier isn't quite as tight as Bob's. Never had to machine down the new
lower burr to get it in either. Fortunately never damaged the upper burr
carrier receiver threads.

That sucks and is somewhat surprising (though anything and everything can
and will have failures). Wonder if something like a rock got jammed in the
burrs and the motor over heated or something. Though I thought there was an
over heat shut off thermal reset, not 100% sure on that. I've easily ground
well over 500# on my Rocky with no signs of motor weakening or dying.
