power series crank questions

i got some cranks and was looking for some info.   so i hear some of them came with miss matched dates on them?  i have a set with 88 and 89 on them.   does anybody know if this is true?  ive seen alot of mitch match ones so i would think they came that way, but just looking to get a conversation going i guess. 

also has anyone had a issue with the sprocket bolt being stuck? did they lock tite them on?    any tips to get it off ,

i plan on sanding the lil bit of flaws off these and polishing them, gonna try to keep it a lil satin look if i can.  anyone wanna share their methods of pics feel free to post.

Re: power series crank questions

Most of them have the bolt stuck. There is no reason to remove it, just leave it smile

Re: power series crank questions

Mismatched date stamps for the years was common so I wouldn't worry about it...my last set were stamped '87/'88.

Re: power series crank questions

If you have a bench vise you can clamp the allen key in the vise and then use a piece of pipe over the crank arm for leverage. It usually comes out pretty easily that way. Before you do that set the crank arm on your workbench, set the allen key in the bolt and give it a few medium taps with a hammer to break it loose.
For the satin look I polish them first and then go over them lightly with red Scotchbrite pads.

Re: power series crank questions

My guess is the bold is loc-tited in.  Personally, I wouldn't remove it.  If you're going to assemble the cranks on a bike for a show build, the sprocket would hide the polish detail around the bolt anyhow.  Just my thoughts.

Re: power series crank questions

all good info.  im gonna try that method to get the bolt out.  will try tomorrow.

here is an extra set i started to test sand.  i wanna get it right before i strart on the set for my bike.

so i didnt sand all the flaws off, i felt that i would take to much metal off and they wouldnt be as good then,  a few lil marks aint gonna make them look bad i dont think.   

so i sanded 120, 220, 400, 600, then used a brillow thingy i had, then i wipped them down good with mothers polish.   i could see some scratching that i really didnt care for so i then rubbed down for a bit with 2000, then mothers again.   its a lil more shinney than i wanted, but minimal scratching. 


anyone have pics of a satin finish that they did?  would like to see that.   the one in the link you guys posted seemed like they had scratching that wouldnt be to my liking.

Re: power series crank questions

these marks are not very deep but i didnt wanna deform these by taking off a bunch of metal. 
there both 180, the stamp was kinda lite on the one before i touched them.  they are dated 88 / 89

Re: power series crank questions

Leave the bolt in... Not worth trying to get it out.. this is common on these cranks..  Trust me not worth snapping it..

Re: power series crank questions

Very Nice Work sir... The Original Finish was done in a Rock Tumbler Polisher... Or Finishing and Deburring Tub... That is how they got their Matte Finish back then even tho they still looked shiny. Depending on the size of the media and slurry used in the tank Back then... Look at this Video and Imagine 100 sets of cranks rolling around in there instead... My Powder coater has one of these and I did a set of cranks in there... Came out amazing...

Re: power series crank questions

bump on an old thread.

I am doing another set right now, I have done several since this thread was created and have came up with new ideas since.

I have a way to get the sprocket bolt out, but its difficult. its imperative though for having the cranks anodized.

I will show some progress as it happens. here is what I started with.
