    Hi Guys

    Do you know if Yamaha used the same thread on the oil cooler through bolt to the crankcase on the XJ series and Diversion engines? I am wondering if the one from the 900 Diversion pictured is an M20 with thread pitch of 1.5?

    Probably not much help, but I'd start with the parts catalog and compare oil cooler bits from the different bikes. If that threaded part happened to have the same part #, that's a good bet it's the same.

    yamaha would not change a part if it was not need to change but I do not have access to part numbers.
    yambits may have the part number for the diversion 900


    83 900 part number click on part number and you will see all the bikes the union bolt fits for US bikes

    Plate adaptor for 900f is 5N1134610100 from CMSNL

    Diversion is 4KM-13461-00-00. They look identical but have different part numbers unfortunately.

    sometimes a new part number is the same thing just an updated part number. I see it alot with xj parts on partzilla where they list both part numbers with the old part number lined out.

    I can get parts off E Bay so I think I will buy them and see if I can convert my bike to the spin on filter. That is good about the different part numbers, being the same part. Yamaha probably used the same parts on all the XJ's. I read a write up on the forum and here is one I read on other Yamaha machines.

    If you are going to keep the motorcycle, those spin on filters are very nice. Once you get used to the OEM type it is not too bad. You can find OEM from $4 and up, but you are correct, that spin on filter is very nice.

    Here's mine
    https://www.xjbikes.com/forums/threads/spin-on-oil-filter-for-xj900f.124259/#post-624325

    The plate was from a Divvy 600 iirc, and I had to shorten the central bolt by 3mm as I mention there, to securely tighten down onto the cooler adapter and squish the bit O-rings behind it. I don't recall whether I used the original central bolt or got one from a Divvy 900.
    Thinking back on it - my original cooler plate is slightly different to a later one, hence the need to alter the spacing. Same diameter, different thickness. From what I recall looking at all the XJ cooler adapters I could find, there are some differences, but they all fit in a mix and match way, but some need slightly adapted, like mine. As far as I know they're all the same bolt thread.
    The total price was dirt cheap (about 30 quid), which made me laugh out loud at the price quoted above for the converter plate sold by CMSNL.

    I'm using a Mann filter.

    Further to above, the filter I'm currently using is a Mann W67/1, which is a short body. I also have a W610/3 longer bodied one for the next change.
