I have got an ordinary office chair. One of the castors broke but the
distributor (dpauk.net) has quite efficiently sent me a set of castors
(all five). (I write "quite" as they first sent out a set of the wrong
castors. But both sets have been sent for free which is pretty good -
the chair is a fairly low cost model.)

But I cannot see a way of removing the "spike" part of the broken
castor. I think you can see clearly what I mean in this pictu

I tried pulling it out using pliers - but it seems to be extremely
firmly fixed. The new castors have the "spike" already inserted into
them. The bit that sticks up from the new castor has a metal
circlip-like object on it. Any ideas?


You need a flat U shaped metal bar preferably to fit in between the
metal
and plastic castor which would allow you to prise it off.

An open ended spanner might do it? or a hefty blade screwdriver?


You made me look again. Man in chair shop had said it was impossible to
remove the castor from its spike (something about the castor being
moulded onto the spike when it was made). So I was looking to remove the
spike from the web of the chair. And that was proving to be very
difficult. (Zero space between the collar on that and the web of the
chair so impossible to get anything in to lever it.)

I have just successfully done what man in shop said I couldn't but said
I should - screwdriver between castor and it's metal spike. A minute of
pushing/shoving and it was out. Castor now attached to spike on web.
Chair repaired.

Thank you - sometimes the right nudge is all that is needed.

Although common it frequently goes undiagnosed.

Confucious say : Man in shop big nob. :-)

They are pushed onto to the spike during assembly and not moulded around
spike.
As you have found out they can be prised of with a screwdriver as of one of
my suggestions.
Castors on 3 piece suites are the same idea.
