I have a Tioga bear trap bb attached to a takagi opc, and want to remove the spider to clean it. What size is the nut between the spider and the drive side bb cone?
I must have a crank spanner that fits, because I fitted it in the first place, but can't find it so need to get another...

I still use one of these - old Raleigh bike spanner! Seems to fit everything

Sure it's a 30 or a 32 but needs to be slimline

Yep, pretty sure I have one of these somewhere.... Just need to find it.
All time classic bike spanner! Any chance you can measure the big gap for me?

32mm or 1 1/14

The old raleigh bike spanner is too small.

So now I need a super thin 34mm x 2mm thick spanner that can get in between the spider and the BB cone...

any ideas?

How would a vice help?

Normally the cone screws up against a washer which is up against the spider, so it's the cone you need to loosen.

As they usually don't have flats for a spanner I use a vice, vice grips or stilsons.

clamp the nut

turn the crank

bobbbbsy · « **Reply #10 on:** April 14, 2015, 12:15 PM »

The bit between the spider and the cone/backnut is a washer / shim. How do you hope to loosen it when the cone/backnut is clamped to it ?

That Swan Guy · « **Reply #11 on:** April 14, 2015, 02:19 PM »

how has this thread got so confusing?

to take the spider off you need to remove the nut holding it on to the crank.

either you take it off using a spanner and turn it aginst the stationary crank or you clamp the nut and turn the crank against the staionary nut!

whether there is a washer/spacer in between the nut and the spider is irrelevant!

i use a dirty great 18" long 1/2" thick adjustable.. plenty of leverage !! Why do you need such a thin spanner?

fook knows

I think we need pictures of wtf is going on here

Here is the offending item, how do I get at that nut?

pickle · « **Reply #18 on:** April 15, 2015, 01:39 PM »

doesn't that seal just slide off back over the crank leaving you with access to the nut?

OldGooseGuy · « **Reply #19 on:** April 15, 2015, 01:46 PM »

The black seal will come off, but the bearing cone is still there hard up against the nut, and bigger than it, so you need to get in between.

Is the nut actually part of the cone, or are they separate?

pickle · « **Reply #20 on:** April 15, 2015, 01:52 PM »

If the seal comes off away from the chainring then just get a huge set of mole grips on it

OldGooseGuy · « **Reply #21 on:** April 15, 2015, 02:04 PM »

Mole grips will chew the edge of the bb cone, and I want to reuse it...

pickle · « **Reply #22 on:** April 15, 2015, 03:17 PM »

not if you're careful and who's going to see it once you've refitted it?

All is now clear

I just widened an old Raleigh bike spanner with a file and it seemed to work fine on mine. Fingers crossed someone has not over tightened it though.......

put that cone in a vice, turn the crank, it'll all come off
