    Default Adding Oil Cooler/851/888

    adding oil cooler/851/888
    I have added an oil cooler from a 91-98 900SS to my 92' 851. Here's what's needed, assuming that you have the cooler and oil lines from the SS. 2 ea. vibration dampers (cooler rubber mounts)(hopefully you can get these with the cooler) 70010111A, $8.46 ea. 2 ea. oil cooler nipples, 81510051A, $10.12 ea (these could also be gotten from 900SS w/cooler and lines) 1 ea. Flapper Valve, 79910541A $11.68 1 ea. Valve cover from early 916, 24010111A, About 85- $100 I think,or make a bracket. 1 ea. overhead oil line from 888, #87510191A, $123.46, 1 ea. banjo pipe connector, #77910341A, $4.48, 6ea. copper gaskets,#42020008A, .07 ea., 2ea. aluminum gaskets for engine nipple fittings,#22020008A, .07 ea. (check this number,can hardly read it, make sure it's for an aluminum gasket). Make sure flapper valve goes in correctly,won't work if upside down. A newer oil cooler may work but the banjo fitting is a different size so a different overhead oil line is needed.

    Default cooler parts/pic

    Here are the parts you need to mount a 92-98 SS cooler on your 851/888, minus the braided hoses for the cooler and the flapper valve.

    Hi tiz,
    Yes, all banjo's are 8mm. The hose is from an 888, SP4 or 5 I think. The 916,996 has two 8mm on the engine ends, a 10mm on the cooler end.

    What would really happen if you add an oil cooler? Wouldn't your oil pressure drop?

    Pressure in a fluid is distributed evenly across all surfaces of its containing vessel. So basically no it remains the same. You do have to add the extra volume of oil for the cooler when changing oil.

    Hi,
    I fitted the complete oil cooler system from a 916 to my "92 851 motor, all the parts bolted straight on.

    you can use a 916 cooler with a 916 type cyl head feed hose, or you can use a 900SS/888 type cooler and a 888 type cyl head feed hose. you can't mix and match cause the banjo fitting that comes off the cooler sits on top of the 916 cooler and the banjo bolt faces up and down, on the 888 cooler it mounts from the side and is a different size.
    mine runs the 888 set up and the feed line is a snug fit, i wouldn't know if the 916 type would have more room and therefore fit the 888 type cooler but i doubt an original ducati one would work, a custom aftermarket one can be ordered to fit anything though......

    You can also use a cooler from a ST4 or ST4S if you use the hoses from each. I don't remember if the feed/return hoses are the same as the Ss but I do know that the overhead oil line has a different size banjo.
