Hello , i have this Excavator, CAT BSR 313 rega in Australia and from what i have learnt its made in Japan , i have exhausted all avenues on trying to find manuals/information for this machine through CAT Australia, and currently looking on websites in Japan about CAT excavators , and unfortunately with little to no luck , my search has left me more annoyed than what i was when first started, I am appealing to any one that can help please, with service and part manuals , i am currently in the process of overhauling the machine and been able to reach a stage that i cannot give up now as i spent to much on it .. Even if someone can help with information of a shop that is good for parts on this machine , my searching has been time consuming with no luck
