Repair and replace?
#1
hi just got my bike back after it was stolen recovered, and have to sort out the damage now. the bike is a Reebok BUTE and damage is mainly gears brakes stripped, seems they went to town on the pedals and cogs, not done bike repair for a long time for this type of damage, so need to know how do i get the shaft out, it feels like the bearings have been damaged, and is it better to replace the cogs or just replace the whole lot?

A little hard to understand what you're asking.
I would start here: http://bikeride.com/guide/ to walk you through most basic repair. If you have a question about a specific part, please try to give more detail about what part you're talking about, what the problem is, etc.
Good luck

I assume you mean the "bottom bracket" which is the bearing that let the cranks and pedals spin.
To repair or replace, you have to take the whole thing apart anyway. So start here:
http://bikeride.com/part/bottom-bracket/

It shows the two main types. Long term, the cartridge type holds up longer, but if you have the "loose bearing" type and nothing is damaged, no reason not to clean and put back together. If cartridge, these can't be "repaired", you just replace when they wear out.

Usually the only special tool you MUST have is a "crank puller" for either type. You would need a cartridge tool if you have that type.

many thanks for your patience, been a few years since i worked on this sort of repair/maintenance, only issue i seem to have now is the left pedal will not come away from the bearing post, have taken the locking screw out off both sides and the right side with the cogs on comes off ok, the other does not, and i assume it should, would soaking in wd40 oil and leaving help?

Hard to say without my crystal ball or pictures from the bike...
Assuming it is a regular tapered square spindle bottom bracket and the crank arm (rather than the pedal, which is removed using a 15mm wrench with a loooong lever) is stuck on the BB axle / spindle: If it is stuck and you cannot get it off using the crank puller you might want to check if a washer is still sitting there, you should remove it. If you have already stripped the threads you have a problem. Heating the crank arm might help, penetrating oil might help, more brute force or in the end destructive removal... without any pics it is difficult to tell what is wrong.
