I had not seen this one. A bit more pricey, but for my next internal T47 (hypothetically speaking), I would definitely go with something like this.

You can't have bearing press tool for T47 BB because T47 is threaded bottom bracket. With that said, I have used this tool with good success -

It might be available on Aliexpress and works on almost every bottom bracket. It's not the strongest or hardest material but for a home mechanic it's good enough.

To avoid scarring on the bottom bracket I put a thin cloth on it and then force the tool on it. Then rotate.

What?! Nobody tries to press in a threaded bb cup. There are tools to keep bb nuts from disengaging. Hsaus even posted a link of a simpler version of it.

That is exactly what I saying. Your earlier reply says tool with thrust bearing with some bits - that sounded similar to BB30 / headset press tools and I was replying to it.

Thanks for all the replies and explanations! Concerning the BB - I would be willing to buy a new one if that is easier to install. Any suggestions?

Thanx, Flavio
