m737 blues..

[Double-E F]

Hi,

After successfully servicing the axle bearings on my favourite pedals, pd-m737, I got ambitious and into the idea 'why not take apart, clean and lube complete pedal'..?
Disassembly went well (as always..), but I'm wondering whether I'll ever get the pedal re-assembled again , despite the lovely Shimano schematice drawings.. :roll:

More or less in parallel, I tried to install my newly acquired st-m737 STIs and since the cable on the l/h one didn't go in very smoothly, I took that apart (flawlessly again..), but I wonder if that was the right way to go in the end, as I'm also having difficulty in getting that one back together .

To ensure that frustration didn't get the better of me and would cause irreversible damage any of the small bits, I decided to leave them in the cave and go for lunch :evil: .

Anyone of you ever experienced this kind of blues; any tips or tricks to get out of it?

Cheers :|

I think we all know that!

Pretty ambitious though to disassemble the infamous M737 pedals, I would only stick to the axle and leave the main mechanism untouched.

Leave them for a moment you feel more ambitious! That moment will come for sure. Hours, days, months...

haha...for the last 24 or so years, i've only removed the axles to service the bearings and then soaked the rest of the pedal in my degrease tank, then hit them with compressed air and squirted more grease inside like they came from the factory (side note, where can i get that cool bright green shimano grease?) ...i've never dared to pop them apart, they look like they would explode.

Dismantling STIs.

Good luck with that, as I've just posted on another thread, they aren't designed to be dismantled, reassembly is best left to watchmakers with bionic thumbs........

SPDs are easier, but only just.

I hope you are an extremely experienced mechanic. (Not one who just bolts things together well......)

Re:

Rapidfires are fun and can be frustrating, you just need to keep retrying to get that spring to catch there, while holding this and hope it doesn't pop outbfrom there. But once you get the nack it's great.
The 737 are one of the easier of them


As for the pedals,I'm sure I did that to mine BiTD. Can't rememeber the outcome but I seem to have had Onza pedals on them shortly after?

That'll be Shimano Dura Ace grease, also called 'special premium'. Pretty easy to find - CRC, fleaBay etc

Re:

Thanks for your words of support, fellas ..

I think I might've just pushed my luck too far this time.

I'm absolutely no experienced mechanic: the experience I do have in this area was obtained through numerous rounds of similar trial (and error..!) in previous attempts to scrutinize all that's kept in those small plastic 'black boxes' bolted to my bikes .

Let's just ignore that pile of m737 parts for a while, focus on the work I was actually trained for and wait for a moment of renewed confidence and hope before giving it another go !

Which begs the question, what were you actually trained for then?

Re:

Well, I'm a food chemist by training, but I've moved to analytical biochemistry over the years..

Lately, I find myself investigating the fate of therapeutic proteins once administered to humans.

.. still some bike parts render me clueless, nonetheless.

Re:

Ahh the seemingly simple tasks that turn into the stuff of nightmares.
I've lost count of the number of times I've thought "how hard can it be?" only to discover later that "harder than it looks" or "impossible!!"

I think you should get the pedals back together again with the aid of the diagram and much patience.

The STI's though..... Last time I took one apart a small internal piece went pinging across the garage somewhere, never to be found. Those shifters never worked again. But on the plus side.... I've never opened up an STI unit since, and thus never had any further problems.
