I just got the first of many parts for my next build. A modern shimano Ultregra BB

Open it up and it has it's cool little plastic installer the two BB parts and the infor sheet

I open the info sheet, and no install instructions what so ever. Cryptic reference to professionals and experienced installers going to a web site

I guess the assume most people just use a shop, but this bugs me....I like to have the paper details in the shop when I install.....and my wifi is not great in the garage

I guess it is the new way, but it is a dumb way

will be interested to see if all the other parts in the 5800 105 group i just got are the same

That actually surprises me. Most of the Shimano parts I've bought new have come with paper versions of way more instructions than I could use and in something like 8 languages. Happily my recycling bin is right behind my work stand.

It may be that the bottom bracket installation instructions come with the crankset. The old ones, I believe, had torque specifications and threading direction printed on the cups.

Also, if I'm not mistaken the "cool little plastic installer" is just an adapter to make it work with the old tool.

double checked...no install. the bb has direction and right and left, but no nm

having never worked with this type (does not loo difficult) I want to do it right

I don't think there's any possible way to assemble one of those cranksets wrong. I bought a used one with no instructions either.

If it's like mine, watch out for the two allen bolts on the non-drive side. If you don't alternate when tightening them, the arm can wobble loose while riding. They need to be tightened down pretty tight, I've had two come loose on me when riding.

I'm assuming you have the bottom bracket tool?

thanks for info....no I will need to add a tool to the pile, but that is ok

In the car world Chilton made famous the saying "This is beyond the skills of the average home mechanic". That is when I stopped buying Chilton manuals.

The instructions on Shimano's website are very good. BTW - make sure you get the right size tool - there is like three of them.

That plastic ring is an adapter that fits in the park tool pictured up thread. To shave weight on the newest generation of BBs they made them smaller so the old tool doesn't fit anymore and to save everyone the hassle of buying a new tool they include the plastic adapter ring. Mine worked fine.

The plastic ring doesn't fit all of the old tools, BTW. I have a Pedro's BB tool and a Spin Doctor BB tool that it works fine with (both similar to the Park Tool but open on one end), but I have an Abbey tool (a nicer cup that fits over the bottom bracket and has a slot for a proper torque wrench) that won't work with the plastic adapter. I don't know how it works with the Park tool.

I know this is C&V but paper instructions are pretty old school. Online is the way of the future.

I am old school and I will just have to print the online ones out to have in the shop

what would be the proper hammer for that? 2lb sledge or ????

Last four years or so, no new Shimano parts come with instructions. This bothered me when certain details of a chain's installation (such as logo side towards driveside, and that connector pins be installed at the leading end of the outer link plates that they are pressed into) suddenly weren't in the package, but fortunately my older chain inventory provided these for my archives.

I agree with Colnago Mixte, that the two clamping bolts be torqued alternately many times until fully settled. Also that bb cups be torqued to 30 Ft.- Lbs, with the wrench torque maintained for a period of time, again until fully settled with no further creeping rotation.

Everything's online now. This is to assure that dated instructions that don't reflect updates are not used (and which otherwise can become a liability for the manufacturer, suppliers and OEM's).

All designed to dodge the upcoming increase in tariffs. Lower cost, no info, less import duty.
Lamenting today about the Nixon added 10% across the board tariff increase in an attempt to reduce the negative balance of payments.

Who as a kid watched the prices at the local bike shop jump upon the Announcement of the extra duty.

About 15 years ago, I bought a Shimano 105 brand new crankset from Jenson for about $30 -- one of those periodic parts purges getting rid of older model year stuff, I suspect -- it was the original Octalink and likely had already been superceded by Octalink 2.0. A couple years later, I found the matching 105 Octalink BB. Installed it in a new Soma Stanyon frame and when I opened up the box, I found paper as you describe. Some words about professional installation but no instructiions. Tried to find my 3# copper hammer -- heavy but soft, sort of like out president, and the same color, too, but couldn't find it. Probably loaned it to may neughbor for cracking pecans. Had to resort to a funny llittle wrenchy socket sort of thing. I hope it lasts after this non-standard installation.

There's a lot of pressure from conservationists these days to minimize paper use. It's the PC thing to do. So, I'm not surprised that they just direct you to a website. What I am surprised by is that there is a piece of paper stating this and that they didn't just print it on the packaging. Regardless, it's all available on the Shimano website. It sounds like this may cover the OP"s particular product line...

If I ever use a hammer to install a BB on a steel frame, even a Donald Trump Signature "Extra Special Bigly" model, I'd not feel good until I sent the frame out to be faced and chased again ...

I think one of the benefits of hammer install is that you can just peen around the ends of the BB shell to secure the installation, in the absence of using a torque wrench - "hand-hammered drivetrain installation" a new craft in vintage bike restoration.

@squirtdad, did you find the doc you need online? The tech docs they offer are very good. I agree it's better to read from paper when your hands are dirty and your shop is cluttered, but it's good that the docs you need are available.

squirtdad

Tom,
I did and there are quite good..... I am probably more of a paper curmudgeon than I am bike curmudgeon, I still you the library. But any more at work I would not survive without 2 monitors.

I will just read and print..... I will be installing a ful 5800 105 group on a newly acquired frame, so will have a bit of learning todo with some of the newer technology in cranks and bottom brackets

thanks

Jim

any pro's cons on this vs the ones you can attache to a torque wrench. I am moving from feel to nanometers

cbrstar

You would think it would have the torque specs...But then again I suppose with Carbon Fiber you gotta go with what the frame manufacture says, and it might be a liability if a idiot used the wrong specs.
