Superstar do a socket type tool for about £8, that means you can use a torque wrench. They also do an Aerozine BB, that can have new bearings installed.
I’ve changed the bearings in my HT2 BB, & they seem to be lasting ok. (Branded bearings from Ebay that I packed more grease in to). Doubt they will see out the coming Winter so about to swap an old set of HT2 shells ready to go in.Posted 6 years agothepuristSubscriber
They come with some spacers that you put either side of the BB shell so the cups don’t screw in all the way. If it’s 68mm it’s 2 on the drive side & 1 on the NDS, if it’s 73 it’s just 1 on the drive side. If the existing one is HT2 then just look at what spacers are fitted on that and do the same.
And when you take it out make sure you undo them in the correct direction as the drive side is threaded the opposite way to normal – Shimano ones have a ‘Tighten’ arrow on the shell to help.Posted 6 years agomartymacSubscriber
it will come with spacers, usually 3 of them, 2.5mm each.Posted 6 years ago
the width of the shell will dictate how many spacers you use.
a wider shell will need less spacers.
have a search on youtube for HT2 bb install, there are videos that show you.
when its done, you will be like ‘thats it? i was worried about that?’
it isnt that hard to do.fishaMember
lastly – dont tighten the little crank screw thing on the axle too tightly. it only needs to light-finger tight so that the cranks are touching in against the bearings with no slack. Too tight and you’ll get clicking from the BB at the outset.
Think along the lines of putting a cap back on a plastic fizzy juice bottle. Do it until it just starts to bite, then stop. Dont tighten past the bite point. Or if you do, then back it off and then re-tighten till the bite point.Posted 6 years ago
