Can't remove Pedals.

Sorry that should have read pedal cranks. My mistake.

Quoted message said:

Need to grease my pedal crank bearings but I can't get to the spindle and
bearings till I get the pedal cranks off. Pedal cranks held on to the spindle by a 14mm nut. The
pedal cranks have a square hole that fits onto the squared ends of the
spindle. After removing the nut, I tried to knock the pedal crankss off the
spindle with a hammer, but, no go. I think I need some sort of hub-
puller tool but I don't have one. Any ideas please anyone? Oh! the
pedal cranks are plastic covered so heat seems to be out of the
question. The bike is a Raleigh Mega something with oversized tubing.
Many thanks for any suggestions.

Yes, you need a puller. Or an angle grinder.
There isn't really any substitute for a puller, go down the shop and get
one, they don't cost that much. Make sure you don't leave any washers in
before using.

Using percussive maintenance is probably not a good idea.

Stuff shown on the above is fine, with the following additions for the
original poster:

The cranks are square-taper. So, the stuff in the article about aligning
all the splines on the octalink doesn't apply.

An bicycle crank puller (extractor), plus a decent spanner to wind it in,
should do the trick. If spanner won't shift the crank, then put an extension
tube over the spanner (eg. 3ft of car exhaust pipe) and gently push down at
end.

A bicycle crank puller should cost under £10. Without the tool, it will be
a struggle with a fair chance of doing more damage than good.

Just hope you haven't done too much damage with the hammer.

If you can't afford a crank puller from the bike shop to do the job
properly you could try riding it with the nut off. It usually loosens
up pretty quickly but don't ride it once it starts to loosen or you will
damage the crank taper.

( Remainder of list of extractors deleted and not inspected).

There is a slight difference between the first and second on the above list.
Its small, but I think signifcant.

The first extractor has a domed end. Its meant for older bottom bracket
axles which had a stud at the end, and the crank is held in place with a
nut.

The second extractor has a flat end. Its meant for the newer bottom bracket
axles which have a threaded hole at the end, and the crank is held in place
with a bolt.

If the first type (domed end) is used on a newer axle (threaded hole), the
end can dig into the end of the axle. It usually works, but not ideal.

On my bikes, I have a couple with studs on end of axles (dating from before
1990, though the axles are still available as spares). All the household
bikes with cartridge bearings have threaded holes.

I think either sort will work better than a hammer. :-)

I think I remember using a 5p coin to solve this problem. Put the coin
over the hole in the BB axle and wind the domed end of the puller
against it.

There's inflation - years ago a ha'penny bit would have done the job.

Tony Raven. First Prize goes to you. All my thanks. I knew there
would be a more lateral method to get the cranks off and riding with
the fixing nuts off quickly loosened them up nicely. It only took
about 100 yards. Thank You. Bearings now greased up. Job Done.

I would suggest using a farthing, but they're too valuable by now.
