Crank Removal - Bosch Active Line

[Matt Vinyl]

I bought a simple crank removal tool online (picture) but it doesn't work on my Bosch Activeline motor. Can anyone point me in the right direction for the right tool please?

Hey Matt - that looks like the right tool (on my phone) to remove the cranks. Take out the centre of a crank with a Allen key and then insert and screw in the black end into the thread. then you can use the silver end with a spanner to push the crank off the spindle.

might help

Make sure the silver end is fully unscrewed each time you use it before you fully screw in the black end. Otherwise the black part will not engage many threads in the crank arm, and strip the threads in the crank arm. (You can learn by my mistakes.)

I don't know about active line but the Performance CX has a hollow axle and the pin bit of my extractor was too small and went in the bore instead of pushing on the end of the axle. My answer was to get a bit of 6mm rod that goes right through the axle and engages on the crank bolt on the other side.

Most crank extractors are supplied with a fitted smaller push plate, and a larger plate which can be slipped over the smaller one for a bigger opening.

Thank you all for your replies. I have the same problem as WavyDavy in that the end of my tool has a small diameter that goes in the end of the threads rather than pushing on the spines. The Bosch Crank Puller mentioned by the e-bikeshop.co.uk specifically says not suitable for Active line motors!

Also an ALP owner.
I had the same problem and used a short counter sunk head hex bolt to plug the hole, I can’t remember for sure the size as I have screws and bolts scattered throughout my garage, maybe 6mm or 8mm.
Also as the cranks can be blumin tight, I warm them with a hot air gun first, I’ve found a warm crank comes off easier than a cold one

If you have the smaller spline crank, the correct tool was linked in the very next sentence in that link above:

"Please note: This tool does not work with the 2018+ Active Line / Active Line PLUS Bosch motor as this has a smaller spline. You will need to use this tool for these motor types."
