My CT20 off my 3tgte is poked,heaps of radial play in the bearings/shaft + leaking oil seals,this is the first time iv taken one apart and need a little help from all u experts out there,the pics below show how far iv got,so.....how do i split the center bearing section from the turbine valute/housing,ive removed the compressor wheel but not the turbine wheel(i dont have to do i?) + removed the internal circlip behind the turbine wheel but she wont part,wats the secret?
