Specialist tools...pah.
Veloce BB with Veloce Power torque cranks, I notice a little knock lately as I pedal hard...could be pedals but I suspected the BB. Proper tools are expensive but at the end of the day it's just another puzzle to beat.
Using a 14mm Allen socket, 14mm spanner on the hex, remove the end plug, remove washer that's so easy to miss and refit the end plug till its sitting maybe 5mm proud. Using normal pullers and a bung to prevent the puller spindle going inside the end bung...and a fabricated plate to protect the back of the crank arms...pull the crank off so far, loosen end
bung a bit more...repeat until the crank is off. Took maybe 15 minutes.
Non drive side bearing was dryish and very slightly notch, remove seal, clean and work in new grease, refit seal, reassemble.
Drive side bearing seemed ok.
Chain wear measured..0.75%...time for a new chain, pronto. Chain cleaned and lubed.
It's like being at work...I PPM (planned preventative maintenance) stuff all day
Edited to say...im happy and careful not to over do stuff...for instance using the end bung to press against may (and equally may not..i dont know) result in failure of its shoulder. I'm not suggesting there is no risk and there is no danger of damaging something, but tread carefully and it can be done.
