481.1 | wouldn't consider myself an expert | OPUS::GAGNE | | Wed Oct 07 1987 15:55 | 13 |
| Hi, If I remember correctly, you can use the dust cover on the
crank arm as the puller. The allen wrench that fits the allen bolt
should fit through the hole in the dust cover. You shouldn't have
to purchase a puller for this type of crank. All you have to do
is turn the allen bolt counter clockwise and when it hits the dust
cover, the crank arm should start coming off. It has been a little
while since I've seen this so one thing that you should do is make
sure that the dust cover is made out of metal. If it is made out
of plastic, it will just break.
Hope this helps

481.2 | I have one. | TALLIS::JBELL | Wot's..Uh the Deal? | Wed Oct 07 1987 17:50 | 13 |
| One other little thing is to check that there is the little plastic
slippery washer behind the metal dustcap like part. It makes it
easier to turn.
Does anyone know why they stopped making these?
As a touring biker, I thought that it was a great idea; crank puller
capability without having to carry the puller. I have even used it to
pull a friend's crank when he had stripped it with his regular puller.
(It threads in further).

| Watch out! That metal dust cap isn't very thick or strong -- when I had
Shimano 600 cranks, I stripped the hex key holes in mine simply trying
to take them off! Then it was a REAL pain to remove. Once I got them
off, I threw the caps away. Unless they've improved them drastically
in the last year, I can't imagine how you could use them as crank
pullers...

481.5 | crank arm stuck on - HELP! | USCTR1::PJOHNSON | | Tue Mar 07 1989 12:24 | 16 |
| I was trying to overhaul my bottom bracket last night and I was
unable to remove the left crank arm (Campy Chorus). I have
a Park crank removal tool (15mm) and it fits the crankset set, but
the darn thing won't budge. I slightly stripped the threads, so
I decided to back off and consult this notes file. The threads
are still o.k. but the tool doesn't fit quite as snug as it used
to and I'm afraid if I keep bearing down on it I'll be in the market
for a new crank set. I sprayed the crank bolt with WD40 before I tried
to remove it, and I also tried tapping the crank tool with a hammer
(lightly).
Is there a solution that I can put on the crank bolt to free things
up (e.g. the opposite of Lock-Tight)? What should I do?

One thing you can try is to buy, rent or borrow a small automobile
gear puller. This would have arms to grab around behind the
crank arm and a screw to press in on the end of the shaft. It
would probably be best for your crank if the fixing bolt (or nut)
were not removed but just loosened a turn... this will hopefully
protect the threads of the shaft from damage. Many car parts
dealers and rental places can rent you a gear puller.
P.S. A car battery clamp puller is almost the same device and
would be about the right size.

| Re .5:
Just a thought - why not pour boiling water over the crank arm just
before you try to remove it? The expansion might make all the
difference.

481.9 | Better technique or Use a bigger hammer! | BOEHM::R_WOODBURY | why silver bullets!?!? ... | Thu Mar 16 1989 11:37 | 31 |
| I'm going to assume that you've never used a crank remover before, so
forgive me if I'm wrong.
First, have you removed the 15mm bolt? (I know it sounds stupid, but I
just heard of this happening the other day to someone).
Okay, next thing to check is the center part of the crank extractor:
make sure it's backed off all the way so the threads on the outter part
can achieve maximum engagement in the soft aluminum arm. If you didn't
do this, I can understand why the threads got messed up: all that force
was being concentrated on one small area. If that was the problem,
before you try removing the crank again, read the next hint.
Try the boiling water, WD-40 (overnight, at least) etc., mentioned in
other replies. Then, do the following: 1) lean the bike on its side, so
you can support the right side of the crank on a solid wooden block; 2)
place a solid piece of wood (like a 2x3) squarely against the tight
crank arm; 3) hit the wood with several sharp blows as if you were
trying to push the crank ONTO the arm. This may seem silly, but the
sharp impact, applied as it is, is sometimes sufficient to break the
bond the forms between the aluminum crank and the steel.
If you still can't budge it, it is still possible to remove the fixed
cup (right hand side, and, if it's British B.S.C. threads, left-hand
threads) and pull the axle out like that.
If you get the arm off, put a thin film of grease on the axle before
you reassemble it.
Good luck!!!

481.10 | A subtle twist on -.1 | CURIE::WAGNER | | Thu Mar 16 1989 11:45 | 8 |
| A slight modification on .9 is to put crank extractor under tension,
and then smack it with a hammer as described above. (Be sure to
use pieces of wood to support the down-side crank, and as a buffer
between the hammer and the tensioning hex on the extractor.) This
worked very well for me once when I was having difficulty removing
a crank.

481.11 | Don't forget to remove the washer | CCYLON::SCHULDT | Larry Schuldt - WA9TAH | Thu Mar 16 1989 11:56 | 4 |
| My Shimano 600 cranks have a washer underneath the bolt. You must
remove the washer also, or the crank extracter tool is bearing down
on the washer instead of the bottom bracket axle.
|
481.12 | | TALLIS::JBELL | Ceci n'est pas une pipe. | | Thu Mar 16 1989 12:23 | 5 |
| Another thing to check is that the middle part of the puller fits into
the square hole. Sometimes and old puller will be mashed enough that
it doesn't fit anymore.

Well, what now ?
Will you be reassembling it dry ?
with WD 40 ?
With grease ?
Boiling water ? :-^)

481.18 | crank/axle - to grease or not to grease? | USCTR1::PJOHNSON | | Mon Mar 20 1989 14:05 | 12 |
| RE: .17
I cleaned everything out with kerosene and WD40, dried it off, put
in new Campy bearings with Phil Wood grease. I didn't put any grease
on the axle/crank connection because I seem to remember some contro-
versy about the grease/steel/aluminum bonding???
Everything is back together. I was all set to ride to work this
morning but my thermometer said 18 degrees, so I chickened out.
Maybe tomorrow.

You just experienced the steel/aluminum bonding problem.
The controversy that was addressed recently in THIS conference was one
of incompatible specs., though most of the readership wanted to not
acknowledge that.

| re: .20
Matt, you raised a point that I've wondered about. How often should
I do this type of maintenance? I rode about 5k miles last year
and I'm thinking of doing my headset soon. Is a yearly overhaul
too frequent for bearings (i.e. wheels, headset, crank, pedals,
anything else?)?
On my old bike I owned it for 12 years before I got into cycling
enough (2 yrs ago) to venture into the crankset and wheel bearings.
By that time everything was pitted and replacement parts were impossible
to find. Am I over compensating for that mistake?

481.22 | ONCE A YEAR IS CHEAP INSURANCE | AKOV11::FULLER | | Tue Mar 21 1989 10:44 | 9 |
| A complete overhaul once a year is a good idea. Not just for the
sake of cleaning the bearings, but to not allow any corrosion of
threads. When you overhaul the bike, the frame should be stripped
completely then reassembled with grease/lube in appropriate places.
If maintenance is needed on the road, it will be quicker to make
the needed repairs. If you do a lot of wet/dirty spring riding,
it is advisable to repack the BB and perhaps hubs in early summer.

| RE: .22
Unless I misunderstood, Phil's talking about REPLACING the bearings
every year, not just cleaning and repacking them. I'd recommend the
latter, but I'd say the former is overkill. You can usually tell how
worn a crankset/headset/hubset is by examining the cups or spindles
that the bearings ride on. (Also by seeing how dirty the grease is
getting...) By the time you need to replace the bearings, you usally
need to replace the cups. (Kind of like replacing the chain when you
replace sprokets.)
I remember disassembling my headset after a year, and finding the
grease still bright blue, no wear, no pitting, nothing. In a way, I
was happy, but then I thought I had gone through so much work for
nothing. Worse, I wasn't sure if I could reassemble and adjust the
thing as nicely as it obviously had been before I touched it. My
father's dictum kept ringing in my ears: "If it's not broken, don't fix
it."

By the "blue stuff", do you mean automotive axle grease ? I don't
like the fill_would ripoff either, but I find axle grease a little
heavy for my tastes. You can get a lifetime supply of something middle
of the road that will do the job for a middle of the road price.

If you go to any auto parts store, you can get a big tub of
lithium grease for the same price you'd pay for a little tube
at a bike store. As far as I can tell it's the same stuff.
