In one of my road bikes i wanted install different bottom bracket. I cant screw in the bottom bracket i take my bike In LBS and tell me needed use the bottom bracket facing too.l. Is charge me $30. When i come back home i see the mechanic had install wrong the crank arms. In wrong angle. I should go back at the LBS and show that mistake? Is not should the mechanic be more professional? Also how i can see if the bottom bracket is good? i ask the mechanic is tell me is good but i turn the crank with my hand in one spot i feel is little harder to turn.

I don't understand. Pictures would help.

So let me try to read between the poorly written lines as best and as far as I can. The Op has a threaded BB and shell. He wasn't able to thread in the new/replacement BB. He took it to a shop, at pick up he was told that the shop had to face the shell and then installed the wrong brand/model/kind od crank arms, some how at a wrong angle. this was not questioned or noticed at the time of the pick up. Now, later, the Op wants to know if het should return the bike to the shop. He is also wondering about the BB, given the crank arm difference and that at one point when rotating the cranks there seems to be a tight spot.

All that is straight enough. But I agree with HB that details (which photos would provide many of) are missing. Given the poor writing (just bad command of the key board or a bad translation device??) (but given the cost being stated in dollars I assume we're dealing with some one in the USA) some might question the OP's perceptions or judgments. Some BB do have tight points in their rotation as seals are not fully broken in when new. Some are adjustable and when done well will be very free turning. Some are very dependent on good shell facing, others far less so. Do we know if the OP's reference to facing is really just that or a mistaken reference to chasing the shell's threads (a far more likely situation IME)? And the wrong angle thing is another oddity. Some arm/spindle designs do allow for off angle mounting (cottered ones as example) but many are keyed to align only one way. If we knew the brand and model of the BB and cranks we might be able to read deeper. If we had a simple photo or three we might discern even more.

I'll look forward to a greater understanding of this situation. But if the shop did do something wrong I feel the OP owes it to the shop to have a chance to do the right thing. Maybe the mechanic needs some feedback and/or better instruction by their boss. Andy.

sorry i cant take pictures now. But i fix that problem my self. The mechanic had install the crank arm in different angles. I am home mechanic i have learn some thinks my self. I deside replace the bottom bracket is ultegra 5500. I replace with sealed square taper bottom bracket. is used is have some play i look tommorow in my parts if i have one square taper bottom bracket with external bearings. i have install in one old road bike and is turn real smooth. i like do experiments on my bikes and try make them better.

What is missing from this equation is what job you discussed with the shop to have done when you dropped the bike off. Did you discuss and hire them to face the bottom bracket shell, install the bottom bracket, and crank arms? OR did you just discuss and hire them to face the bottom bracket?

Another thing...if you can't screw your bottom bracket in, that is not a sign that your bottom bracket shell needs faced, it means your bottom bracket shell needs to be chased with an appropriate tap.

If all you discussed and hired them to do was face or chase the bottom bracket shell, then they may have just bolted the cranks on to keep everything together with the thought that you would finish the job at your home workshop.

i see you are good mechanic. what happens with my bike is. Because the bottom bracket is was bad and i could install the other bottom bracket i had. i take the bike for opinion in LBS. the mechanic tell me the threads need chaced. I tell do that job because no have that tool. is do tye job okay. Ask me if i want install the crank i tell yes. But when i come home i see have install the crank arms in wrong angle.

It's nice to have the right details the first time. It keeps us on track and doesn't give us a reason to either call you out or just stop trying to help.

Again if you want to be part of the solution and help the shop avoid the next mistake then you'll go back and explain the situation, in well understood detail, and ask them to review what they did. So both you and the shop are on "the same page" at the same time. Then you can go forward with figuring out the path to the right results. Asking us here won't do anything to help you fix the situation.

BTW $30 for a BB thread chasing is about right. Andy.

I still don't understand what it means to install the crank arms "at the wrong angle".

OP, because your writing is not very clear, you should post some pictures. That will help others understand what you are saying, and offer answers.

At this point, I'm not convinced anything is wrong with your bike.

While it is not safe to assume anything...I imagine the bottom bracket and crank are an octalink/isis type because with a square taper bottom bracket and crank a misalignment would be extremely noticeable. With a splined type bottom bracket/crank the mechanic may have installed one crank arm one spline off causing the cranks to not be 180* from each other...I can conceive of this happening if the mechanic had a lot of things going on and was trying to get the job done as quick as possible, became distracted during the job, or was just inexperienced. None of these reasons are acceptable excuses for poor quality assurance.

My recommendation is to the OP is to take your bike back to the shop and show the problem to the mechanic and/or shop manager. They should have no problem correcting their mistake. Or if you have the tools just remove the crank and reinstall at the correct position and possibly find a different shop in the future if you no longer trust the one that did your install.

If you have a torque wrench, I would loosen and retorque the bottom bracket cups to the correct specifications as your the binding you describe could be because they were installed a bit too tight. The more I process what you have posted it seems like the mechanic who worked on your bike either did not have a lot of experience or was just sloppy in his work, but who knows.

This issue is not that big a deal to be too upset about....I would not go back to that shop unless you wanted to discuss having them return some of what you paid for this job.

Good luck.
