My dad cleaned his bike today, and decided that the pedals felt rather
awful. No problem, I thought: Strip them down, clean and grease them,
and put back together.

Nope! They have never been serviced in the 8 years he has owned the
bike. They simply would not come off. I snapped an allen key in the
process . Fortunately it was safely concealed inside a seatpost which
was being used as an extension lever, so my fingers were uninjured.

Then the plan of action was to remove the crank arms so that dad could
mount them in a vice at work. Again, Nope! The crank extractor (the
part of lesser diameter) managed to break free and is now lodged
inside the BB axle.

Bummer. What now? Take it as an excuse to buy a new bike?

I once cut the BB off in a similar situation. A 9" angle grinder with a thin
blade might be able to get in between the crank and the BB shell. Cut it off
there (takes care!), then you can hammer the little bit out of the crank at
your leisure.
(this course of action depends on treating BBs as cheap enough to be
disposable)

cheers,
clive

Forget allen keys. You need a pedal spanner.

If these are the pedals without flats that have to be removed with an
allen key and only with an allen key, then they ain't ever going to
come off.

If they have flats, then you may have some hope, but....

....given this, I'd just accept that the entire bike will be seized solid
and treat it as a learning experience.

I have a 2-arm gear puller which theoretically should get cranks off
without an extractor. When I had a seized crank years ago it still
wouldn't shift them. Since then I have always used anti-seize on the
tapers, so there :-P

Try a little heat, it's truly amazing what you can do with a little heat 🙂

Can you get a container large enough for the pedal and the end of the crank.
Fill the container with boiling water and immerse the pedal and crank end
for 10 minutes.
Then try undoing it.

I assume you have already applied penetrating oil and left it overnight.
The right hand pedal has a conventional right hand thread but the left pedal
has the unusual left hand thread.

My dad's joking reply to being told this was "I'm nearly 60. I think
I'm becoming too siezed up too".

Presumably while wearing very thick gloves.

Bloody wish I had done now!

Dad attacked the left hand crank with a hack saw to remove it. The
right side came off easily. Bottom bracket was successfully removed
with brute force and penetrating oil.

Went to Halfrauds to look at chainsets, and to buy a new
crank-extractor. Chainsets available were either more than 200 quid,
or real budget end heavy-as-hell jobs.

There was, however a very tempting offer: A Suntour right-side only
triple chainset which exactly matched the old worn-out one (48/38/28).

I already had a spare LHS crank of the same length and colour. So we
purchased the Suntour for a bargain 8 quid.

We also bought a suitable bottom bracket.

When we got home we discovered that the BB was in the wrong box. What
was labelled as a 113mm Tapered was in fat 113mm Splined.

We also discovered that the tapered square of the Suntour crank was at
45 degree offset to the spare arm. It also appeared to be at 45
degrees offset to every other crank I have seen.

A quick check of SJS website convinced me that this was indeed a very
unusual design. Only one of the chainsets on there had this
arrangement.

Typical Bates luck.

B*ll*cks!
There's a bloke older than him comes out off road with us.

When you've got your dad's bike sorted send him down the park to learn
some BMX tricks!

Just mount it and let your dad re-learn cycling the 135deg way. Just
think on Mondays, Wednesdays and Fridays he can have a 45deg lead on
the right leg, and Tuesdays, Thursdays and all weekend he can have the
more relaxed 45deg lag :-).

I rather expect that we'll see this on Sheldon's site sometime soon.

A cure for those times when the pedal spins backwards? Banish those
TDC blues.
