    Remember all diesel oil specs are backward compatible.

    Do you have a serial number? I was able to get parts books and operator's manuals for both a gray market 311 and a 312. I think they are printed in Japan and shipped direct. I could call and ask if books are available for your 307 if you like.

    thanks for your interest!
    The problem is that i am located far away....!
    I have a parts manual for the American 307 and seems to fit to my ssr but is not full compatible i think.
    So, can you order parts according to these books? i mean, the serials are Japan or American?

    The serial numbers of our machines are in the range of the books.
    The are written in Japanese. For parts I look at the picutures and find the part numbers. Can be a real problem with subsets.

    Seems like your looking for an opperators manual which will have lube specs, refill capacities and maintenance schedule. I wonder if any 307 manual would work?

    My serious problem is to order the part which will fit to my machine. Dealers here cannot help me, they can just order by serial.
    So, if i have the Japanese parts book and look at the pictures and find the part number i need then i will have to match it to the American parts book and order by the American serial??? Is that correct?

    With a Japanese parts book, It's written in Japanese but the part Numbers are the same. I haven't come across the problem of finding a part number in the book that didn't correspond to an actual part.

    You find the number and give it to the parts department.

    I dont' think I was very clear. Hope I don't muck it up further:Banghead

    -You find the part number in the Gray Market (Japanese) parts book and you place your order using that part number.

    -There is no need to cross-reference with the American manual.

    I know EXACTLY what your saying. They'll ask for your serial number and then say, "I'm sorry, that machine is not in our system. I can't help you".

    Once you get the gray market parts book, you call up and give them the part number directly - no need for the serial number.

    Do not worry, you were very clear, i understand.
    I have checked few serials written on parts on the machine and most of them do not match to the American parts book.
    I think, i am not sure for this, that newer machines like yours and 308 use same serials American - Japanese) and the older like 307 are a bit complicated.
    However, how much did the Japan books cost to you?
    And because we are off topic, which oil do you use for your engine, hydraulics and for the swing motor?

    We have two Cat books- I'll have to check to see what we paid for them but I just bought a parts book for a gray market Komatsu- it was $130.

    Engine Oil- Mobile Delvac MX 15w-40.
    (Have used Chevron Delo 400 15w-40)

    Swing Drive & Final Drives- Any GL-5 rated 80w-90 gear oil.

    Hydraulic Oil- AW 46

    What I use might be different than what the book says.

    remember that the grey machines do use some different parts than the US machines. Matching S/N's does not always work.

    Make sure that you use a HYD oil with a minimum 900ppm zinc. There are several oils that do not meet this critical spec even when new.
