BB30 problems....bearing/creaking problems? (with vid)

The Northern Monkey

I've noticed today that the preload nut (part number 8) isn't tight, and has about 1.5mm space between the bearing shield (part number 5) and the crank arm...

Is there a spacer missing or something?

The extracting bolt (part 9) can't be done any tighter...

adjust the preload "nut" to take out the play make suree the small grub screw is lose before and tighten up after.

The Northern Monkey

Sorted! didn't see the little grub screw!

tiny little fecker, had to try 3 different allen key sets before I had one that fits!

nicklouse

it gave the size in the instructions.

The Northern Monkey

hehe... I mean i didn't have a set that went that small lol! luckily one of my old park tool sets had a tiny one on it lol.

How good is the bearing sealing on the BB30?

Mine is now clicking like a mutha flipper :evil: I'm guessing its the Welsh grit but 4 rides?!

Checked pedals and other potentials, but they seem fine.

Seems to happen with any weight on the pedals :evil: Not good when you have ocd. stopped about 8 times to check I haddn't cracked the BB!

The Northern Monkey

is this all i'll need (along with my big allen key) to get the cranks off?

Not remover the bearings, just want to give it all a good clean out.

Good question regarding the bearing sealing and if I'm honest, I don't think it's that good. The bearings don't seem to last very long, but they are cheap(ish) to replace.

Yeah, that's the tool you need.

The Northern Monkey

Cheers Dave, will order one tomorrow

The Northern Monkey

Here we go.... creaking like a mo fo.

Cleaned and refitted afterwards which seems to have fixed it for now.... are the bearing seals really that crap?!

Quick search on the net finds loads the same

Dave_P1

Quite a scary sound when you first hear it as it echo's through a carbon fram very well (in my case).

The Northern Monkey

Right another question... (couldn't find the latest thread... stupid search).

For BB30 bearing removal, all I need is the following?


And a hammer.


And instalation, this and a heasdset press? (already have a headset press)


Not bad for a tenner... as I've already got a press I might as well.

Anyone know where I can get some decent bearings from?

nicklouse

any bearing shop.

IMHO, yes !

The best one I have come across as recommended by dpaulett the Enduroforkseals version.

The Northern Monkey

Today question...

How do I get the drive side out?

I've been twatting the spindle with a rubber mallet for about 30 mind and the fecker hasn't even shifted!

Following this: http://www.parktool.com/blog/repair-hel ... nd-removal

I don't want to ht it any harder! Could it have seized?

Dave_P1

They shouldn't come out without too much bother to be honest. All the ones I've replaced have been fine. I expect you have already checked, but make sure there is nothing stopping it from coming out and you are striking the bearings and not any ridges in the frame.

The Northern Monkey

Just to clarify... tis the cranks I can't remove, not the bearings lol!

Levi_501

Not sure what you mean, but I always find pouring boiling on water on aluminium parts to releaves them.

itsmygame

Him them harder ben it will come out don't be scared of it

not had an issue removing spindles from bb30 boardmans, using a halfords deadblow. http://www.comparethestores.com/product/35/403623121/Halfords-Dead-Blow-Hammer.html
make sure the bearings are properly seated, some first batch 2011s had issues with that.

Knock the shifter into the small ring then unhook the chain otherwise this may prevent the cranks from being knocked out.

Dave_P1

What cranks are you using? Most use a self extracting system now so there shouldn't be a problem.
