DIY Fix Shimano SM-BB71-41A / shell 41x89.5mm

Muise

Hi I have this bottom bracket: Shimano SM-BB71-41A / shell 41x89.5mm

It is pretty creaky at the mo so I want to fix or replace it. I like to try and learn to do things myself, rather than go to the bike shop (unless I need them to fix a mess I made trying to do it myself!). I'm searching for the tools I need, but they seem crazy expensive (£45 is the cheapest I can find, twice the price of the new BB). There are lots of cheaper ones, but I can't figure out if they will work for my specific BB, which I think is a bit bigger than most.

Can anyone point me to the cheapest removal and installation tool that will work for the Shimano SM-BB71-41A / shell 41x89.5mm?

Many thanks

Not sure if it is relevant, but this is the specific bike: https://www.startfitness.co.uk/scott-2017-genius-710-plus-full-suspension-mtb-grey-249566.html

I think this tool will do for installing but haven't found one for removing yet... https://www.ebay.co.uk/itm/Shimano-BB86-BB92-Bottom-Bracket-Bearing-Press-Fit-Tool/283869650368?hash=item4217f31dc0:g:mCAAAOSwzfFeSZjv

I haven't ever removed or replaced a press fit bb before and depending on how you stand ordering an item from China through EBay this is worth at least looking at, costs £15.46.

Type this into EBay search:-

Press Fit Bottom Bracket Removing Tool For SHIMANO BB71 BB91 BB86 BB91/92 New

For Installation and in true DIY fashion I did make something like this to install a new headset which is basically the same procedure except there is another EBay seller that provides this tool which with care, taking your time is safe and will work, it did for my headset anyhow, costs £7.99.
