Wore out another BB

[MattDB]

Hi,
I've recently bought 2 vintage bikes and have been commuting up quite a steep hill. Initially there was no play at all in the bottom brackets but after a couple of journeys with each they've started to creak quite a lot.

I'm 6'6" and 16 stone and wondered if this is contributing - I'm dreading taking the BB out (took me ages on last bike) but is there a particularly sturdy one I should be using?

Depending upon age I would fit a shimano cartridge BB. Will fit most bikes since early 90s.

what are the bikes and the crankset.

The bike is a Raleigh Esquire, I think it's from the late 70's. I'm not sure about the crankset or bb :-$
