Can't remove Pedals.
Need to grease my pedal bearings but I can't get to the spindle and
bearings till I get the pedals off. Pedals held on by a 14mm nut. The pedals have a square hole that fits onto the squared ends of the spindle. After removing the nut, I tried to knock the pedals 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. |

Using percussive maintenance is probably not a good idea. http://www.parktool.com/repair/readhowto.asp?id=120 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. - Nigel -- Nigel Cliffe, Webmaster at http://www.2mm.org.uk/ |

It usually loosens up pretty quickly but don't ride it once it starts to loosen or you will damage the crank taper. -- Tony "...has many omissions and contains much that is apocryphal, or at least wildly inaccurate..."

How about many suggestions? :-) http://cgi.ebay.co.uk/ws/eBayISAPI.d...m=160092030751 http://cgi.ebay.co.uk/ws/eBayISAPI.d...m=120081425582 ( 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. - Nigel -- Nigel Cliffe, Webmaster at http://www.2mm.org.uk/ |
