Hello.

I got an early 80's Huffy road 10-speed with 27" wheels.

I rode the hell out of it and one of the pedals just fell apart. I looked at the spike now sticking out of the right crank and I have no idea on how to get that spike out in order to install a new pedal. And how do I know which pedal will fit there.

In fact, I would like to find out which parts will fit this bike: can I install a cassette with more sprockets? How do I know which bottom bracket to install, how do I know which crankset axle will fit in there?

Please, please help.

Thanks,

Eugene.

If the cranks are 1 piece it's a 1/2" pedal. It requires a 15mm open end wrench to remove. I wouldn't spend any more money on an '80's Huffy than replacing the pedal.

No wait! I wouldn't spend ANY money on a Huffy that old!

You probably need a 15 mm wrench to unscrew that spike from the crank, with a pipe to act as a prybar on the wrench. First let some Liquid Wrench penetrating oil soak into the threads overnight. Since pedals come in pairs you should also remove the left pedal - that one has to be unscrewed clockwise. Take the pedals to the bike shop and get a new pair with the same size threads. Put some grease on the threads before you install them so you dont have too much trouble taking them off later.

I think you would find it cheaper and easier to find a better quality used bike than to upgrade this one - ask about used bikes when you take the pedals to the bike shop - good luck!

Thanks for the replies guys.

Well I will try and fix it up. It would be an opportunity to learn the mechnics firsthand without ruining an expensive bike and acquiring all the necessary tools. Besides, it looks like quality parts are dirt cheap on ebay and it shouldnt be that difficult upgrading most components. I figure the size of pedals can be determined with a caliper.

Okay, so I found the 15mm pedal wrench, but my concern is that the pedal axle that has to removed from the crank is round, not something that a wrench can be used on, at least in my limited experience.

My next question is - how do I take apart the whole crank assembly - bottom bracket and all? I can only see a rather big nut on the left side of the bottom bracket. (BTW bottom bracket is the same as crankset axle hidden withing the frame, right? I just wanna make sure)

Thanks,

Eugene

Normally, there is a place to put a wrench on a pedal right next to the crank arm. If its not there, look on the other side of the crank arm for a hexagonal hole in which to use an allen wrench. There is always a way to unscrew the pedal from the crank arm!

Beware of jumping right in & taking the bottom bracket apart. Why do you want to do that? (I only ask because it sounds like you're new to this...)

It might look as it is round but there should be two flat surfaces opposite to each other where you could use a wrench.

Agreed, there should be some flats on the pedal axle, but on a Huffy, anything is possible. If there are no flat surfaces, you will have to grab the pedal with a pipe wrench or similar.

This link will help you with your repairs. Please note that most of the Park tools indicated can be substituted with common tools and common sense.

Thanks to all those who answered. Yes, I was thinking as a pipe wrench as the last resort.

halfbiked, I am new to this, but I want to learn without going to the store. I would like to replace the bottom bracket and the crankset eventually so the pedal turning would become smoother. That may also involve replacing the cassette assembly.

A little update. I checked the bike pedals and there are two flats on the pedal axles. So as I get my hands on a 15 mm wrench off they come. Then with the help of a caliper I can determine what they can be replaced with.

Thanks all.

Eugene.
