(closed)
Hey Everyone!

7710 is self extracting. you need the appropriate allen key (8mm?) for the bolt. Turn it counter clockwise and watch the crankset remove itself from the bb spindle.

I can understand that service isnt free. Shops need to make money. But this is no harder than filling up two wheels with air. $45 seems like a steep price for that :(

BB is removed with either just the standard shimano BB tool (BBT-32?) . or. BB tool and lock ring tool depending on which BB you are using.

*edit* take a better pic of the crank arm dust cap svp

It almost looks like you dont have a self extracting cap. Looks like its been replaced simply with a bolt/washer combo. You might need to take the extracting cap off the nds arm and use that to remove the ds arm. All that work could justify $45.

However.. with $45 of tools (or less) you can learn to do it yourself ! :)
You should ask to buy the tools from your LBS, then ask them to show you how to do it. They make money, and you learn to wrench a bit on your own machine. Win Win

You need an Octalink crankarm puller, which should cost about $20. Park Tool makes the CCP-44 for Octalink (and the CCP-22 for square taper), or if you want a square taper AND Octalink/ISIS puller in one unit, get the CWP-7, but you use your own 15mm wrench for the handle of that one.

^^^ thats probably your best tool to have in your case.
Having the stock self extractor caps missing..I can understand why they would charge you 1 hr labour. Its fair.

Fair? Removing Octalink cranks and the BB should take a competent mechanic no more than 10 minutes. An hour's labor? C'mon. I would have charged, at the high end, $20.

i dunno what to say guys, but i think the new mechanic in are LBS got a attitude problem, there last mechanic charge me nothing he just removed the crankarm and BB less than 2min and install to my new frame for 2min, i give him $10 for consideration thanks for your suggestion. The good news is i already removed the dust cap by using of scissor and pliers and i break one of my cheap hex 8mm, i might need puller i guess (but the last time i saw the mechanic that removed my crankarm he never used a puller but will see what happen)

7710's have a self extracting bolt. You leave in the dust cap and use an 8mm allen key to take off the crank. Takes literally 20 seconds. You shouldn't need a puller if your 7710's have the right stuff. But you pic sucks wiener and we cant tell if it has the correct dust cap.

Steve. Put yourself in a shop owners spot. 1 hr labour for this job isn't unheard of. It's pretty standard. Still have to tag it, put it on the stand. Wrench at it. Shop insurance.. Blah blah blah. It's fair yes.

Would I pay 45 for that?

No hahaha.

But it's fair...

So the last mechanic did the work under the table for $10 while getting paid his hourly rate, and you think the new guy is shady for charging the minimum standard hour rate?

It's easy to think an LBS is a ripoff, but until you own a successful one, no one really knows what it takes...

I can't put myself into the owner's shoes, but I can tell what I would charge as the mechanic who works in the industry currently and does this sort of shit all day every day. Either way, a full hour's labor charge to remove cranks and bb on Octalink is way too much. Also, what shop charges $45/hr? Most shops have seen do $60/hr currently or more. I wish our industry had more standard labor rates, so shops couldn't undercut each other so much and the good shops with good service would flourish and shitty shops would sink into the ocean.

And yes, some mechanics do work "under the table" while we're on the clock, but some mechanics do a quick service for a regular customer just as a nice courtesy, perhaps while their current customer is on a test ride and they'd otherwise be standing around trying to find an orifice to put their thumb into.
     
March 26, 2015 01:05 PM
so $45/hr is a deal ! :P if standard rate is $60/HR

I think its absolutely fair, as hes probably a new customer coming in and inquiring about work being done. Shops will never ..well most shouldnt...over promise and under deliver. So $45 now can be $10-15-20 when its all said and done.

$45 is expensive for us who have the tools, and who know what to do.

$45 is fair for shops to charge for work.

Buy the tools yourself and fix it up.

Why's it gotta come off in the first place though?

as stated above, Shimano 7710 has a self extracting bolt attached to it. an 8mm Hex Key is all you need.

Now, if you have the cash to pay for a $250 dollars crankset for your bike + $70 for the bottom bracket, you shouldn't have an issue paying an extra $45 to get it removed as budget didn't seem to be an issue when you choose your parts.

I would have done the same if I was LBS owner and someone with Dura-ace components all over their bike walked in my shop.

We havent seen better pics of his set up. His cranks seem to be missing the OE self extracting bolt. But could just be a bad picture and poor lighting.

So did the tools that you bought work for you ok? Curious because I'm looking to buy tools for the same crankset.

Sorry to bump the thread, but just want to know how hard is servicing a dura ace 7710, just has mine service by a bike shop and I feel ripped off. I feel like they improperly installed it, or didn't but enough grease and now my bb is making a loud, rubbing noise every time I go down on my right pedal.

The njs version is completely sealed. The road version you can service them.

Or you can just get the 105 octalink version for half the price of the njs one

^^Would you know what tools I would need to service, I have shimano grease otw.

Haven't taking her a shower, but my right crankarm is loose.. This is the second time the bike shop does this. What do I need to do to tighten it? 7710 BB.

You need an 8mm allen wrench and a master's degree in advanced rocket science.

Well, MAYBE you could get by with a Masters, but I wouldn't trust anyone but a PhD with my 8mm allen.

Thanks for the advice guys! Tighten it up with an Allen key, seems like the bike didn't tightened it up enough and came loose after a couple of rides. PS. Scrod I hope you were the one the packaged my TB14's @ Retrogression, if so I'm keeping the box as a collection item. :)
