Hey i'm trying to take apart a 231J and i can't seem to get the case to split... am i missing something? I took out the tail housing bolts and knocked that loose, i took out the bolts holding the retaining something or other on the input side and removed the two snap rings... inner and outer... and then took all the bolts holding front and rear halves together out and broke the seal... but now the chain is holding onto the front output and rear output so i cant pull the two halves apart. Do i need to take off the front yoke or or the rear hack n tap or what?
