Result at the tip this morning

It looks like it could do with some oil .

Yes quite. I've got a bit of diesel engine oil kicking about. I'm thinking to give it a bath in that and then work each link. Then put it back on. I'll check for wear first though, cos if it's stretched then there's no point soaking it.

Am now attempting to remove the crank set. My 15mm socket is too thick to fit in and get the crank bolt undone. I could do with a thin walled socket, but has anyone else had any success with specific crank bolt wrenches? If so where from? Also with the TA crank, am I going to find I need a non-standard crank puller too? There's a pick of my crank above somewhere.

Something like the above.

Yes a thinwall socket or a peanut butter campagnolo spanner normally works and yes you will need a ta crank puller and i think there are 2 options if i remember rightly

never tried one of those but it could work , i have the Planet x equivalent but never tried it on a ta crank bolt i think i have one of the extractors if you wanted to pop up ?

Ah. TA cranks might be a non standard size. My next door neighbour from three moves ago had one, but that doesn't help. Regarding getting the bolt undone, a standard el cheapo crank remover that doubles as a bolt remover should do the trick.

Here's one I found on amazon: https://www.amazon.co.uk/Silverline...coding=UTF8&psc=1&refRID=479RMDWQRXWBEDEWAD47

Thanks for the offer. If I can get the crank bolt off and measure the threads then I might well come and borrow that from you.

I needed a thin walled socket that wasn't chamfered at the entry. Too late, I realised that such a tool does exist and it's called a box spanner.

 

[stalagmike]

Update: got the crank bolts off using a 15mm box spanner. Had to buy a set of them for a tenner to get the correct size, but I'm sure they'll come in useful for something. If only to fit the crank bolts back on.

Then I took the whole thing down to Corley cycles in MK where their kindly mechanic pulled the cranks for me. There was a funny moment when we were comparing our pulling tools over the counter. My pushing pin was smaller than his. Fnarr.

He did it completely FOC. So I'll probably be back there again soon for something else.

Here's a pic of the TA crank after a go over with bar keepers friend.

What do I need to get this left hand side BB cup out? One of these?

I've had a bit of a go with needle nose pliers but they're not going to work.

Anyone seen cheaper ones than park?

I've seen pin wrenches for £3 to use on angle grinders but not sure that would work.

I doubt that will touch a fixed cup, I use a hammer and drift or a big nut/bolt through the middle (as you tighten the bolt up it undoes the left hand thread.

The other option is to leave it in and just fit a couple of new caged bearings if the shaft/cup are OK and you're sticking to a square taper crank.

Looks like a pin spanner jobby? Can start movement with a hammer and punch then move onto a pin spanner.

Is there enough for a big pr of parrot nose pliers to grip hold off ?

This is the non- drive side so my thinking was to get this side out, clean or replace the bearings/crank and leave the other side in.

There might be. Maybe a couple of mm to grip onto. Are you suggesting clamping the parrot nose pliers around the outside of the whole thing to get it moving?
