    Default Yanmar SD40 & SD50 Cone Clutch Upgrade Kit

    After experiencing the typical "Slipping Cone" syndrome on our NEW (900Hrs) Voyage 500 in 2012, we looked into/identified the cause of the problem.
    It took a while to develop a solution to the problem, which essentially replaces the Yanmar thrust washers with Thrust Bearings (similar to Volvo).
    The Rework also incorporates the Selector adjustment, allowing much closer initial set-up tolerances, and reduced wear.

    This Rework/Upgrade solves the re-occuring slipping Cone Clutch problem on the SD40 and SD50

    If you are really aware of the importance of writing you know how difficult it is to find a proper writing resource. And sometimes every one of us needs it. I suggested you follow the custom proofreading service ThrivingWriter and learn about reading. I like that they have so many different types of services and specialists for each of them. Have a deal with them is always a pleasure.
