Hollowtech II crank cup removal tool

[Rouxenator]

I recently converted my 2x10 bike to 1x10 however I have endless issues getting the chainline right. Previously on a 3x10 bike this is straight forward so I decided to buy a cheap 3x crankset to simplify things. 

 

The crankset I settled for was https://www.buycycle.co.za/mountain-bike/components/cranks/shimano-deore-m591-crank-set/ which will work fine as replacement for my 2x Hollowtech II. Don't care for the fact that it's 9sp since I will be removing all the chainrings and fitting my narrow wide on it.

 

My question is does the crankset come with a tool to remove that plastic cup which fastens it to the BB? If not where can I get it and how much will it cost? Ideally I would like to try and do this by myself.

Apparently after loosening the crank arm bolts on the non-drive side, you can use this

to loosen it.

 

If, by plastic cup, you mean this thing:

I have bought cranksets that come with the tool in the box and some that don't. Your LBS likely throws a lot of them in the workshop bin and may give you one if you ask nicely.

 

In a pinch you can use a large allen key. The tightening torque is VERY low, less than 1Nm....literally only finger tight. It must be loosened / tightened only while the left hand crank clamping bolts are loose. If you overtighten it the plastic cap splits.

If that's what you are talking about then it should be available at any local bike shop.

 

It comes with the BB tool/spanner.

No, the tool to remove it does not come with the crankset but is usually part of the BB tool that you would use to remove the BB cups with (Such as this http://www.chainreactioncycles.com/za/en/x-tools-bb-tool-hollowtech-ii-spanner-fitting/rp-prod10179)

 

Flandria should have some, I bought mine there last year for about R 120 if I remember correctly.

That's also why it is a finger tighten with the crank arm bolts loose - remember also that in the slot of the crank arm there is a plastic piece with a metal pin held in by the 2 crank arm bolts. this also needs removed before fitting the arm.

 

What worries me is that all of this is the same on almost all shimano hollowtech II cranks... I cannot see that it is any different from your previous cranks.

Yes it is the same, except this is a triple blade not a double. This will be the first  time I attempt to do it by myself and not take it to the bike shop.

I have the tool you need to remove the crank bolt and bb cups. A BBB Bottom Bracket tool.

Got it for about 130 bucks at Flaandria in Stellies.

 

Else if you are keen for a drive out to Gordonsbay, you can bring your bike and I will help you remove the crank, or you can borrow the tool if you want to do it yourself

Thanks, for all the feedback, I ordered one of these : http://www.evobikes.co.za/components/pro-bb-remover-hollowtech-ii.html 

 

Hopefully I manage to DIY this and learn a bit in the process.
