    Ws2 tungsten disulfide

    Anyone running this additive to your Yamaha? I added it in my folks 2013 Commander with straight cut gears in the rear end. Made a big difference in quietness and reduced gear wear. Also ran it in my 2014 Commander rear end but was changed to bevel cut gears that year and already fairly quiet. Yeah I know it's a Canned Ham and not near the quality of our Yamaha's lol.

    Technically speaking it's called the final gear when referring to our rear ends on our X2/X4's.

    I see no harm in running it in our front diff or final gear on our Yamaha's. I wouldn't use it with any wet clutch. My warranty is up anyway. So anything I can do to improve longevity. I don't see any down sides on all the searches I read on the internet in using it. Thinking about adding some maybe 1/2gram to my rear final diff during the next service this late spring to experiment. I only will add it one time as everything will be coated. Any future oil changes I won't worry abut adding any more. Before I change the oil I'll get maybe some readings using my infrared temp gun before then after adding WS2. Anyway I'm sure others have used it in the past and can chime in. Anyway let me know your thoughts with anyone that has knowledge first hand with Tungsten Disulfide use.

    Just some of the benefits:
    Reduced gear noise
    Reduced gear wear and galling
    Lower coefficient of friction
    Excellent lubricating properties
    Superior resistance to oxidation
    Lower temp in gear boxes. Big one here as we all know how hot the rear end can be on our X2/X4's. I run full synthetic already which helps.
    Would also be very beneficial with the guys running portals as those little gear boxes get extremely hot with the small oil quantity.

    As a Construction Union Millwright I have rebuilt gearboxes/gearsets in the heavy industrial sector, i.e. Powerhouses, Steel/Aluminum Mills, etc.
    Most of the gear sets are single & double helical gears and some straight.

    I have rebuilt several automotive diffs and depending on the system, some require limited slip additive for the clutch packs and any friction modifiers will causes the clutch pack in the locking differential to slip and miss engagement.

    I don't know enough about our front diff/final drive to make a contribution about additives, however, Yamaha does recommend "Yamalube Friction-Modified Shaft Drive Gear Oil 80W-90".
    So based on that I think it would be suffice to say go for it and let us know your results.

    I just changed the front diff/final drive oil.
    This was the third time in 1k miles. The oil from both diffs was super clean.
    The final drive looked 'brand new' (not like some videos I've seen where they say new and looks like shit to me) and the front looked almost new.
    I used printer paper while draining to look for oil contaminants.

    Since Yamaha recommends Friction-Modified oil in both the drives and transmission, I don't see why you couldn't use it there also.

    I used it in my Commander when I had it. I have some left over and was going to try it in my X4, at least in the rear end.

    Exactly what I was thinking. Can't hurt as the rear end gets extremely hot on our X2's. I still have some left from my Commander as well.

    Check out the Hunterworks Gear Butter. Incorporated with the same “ nano particles” they use in the greaseless sheave to make it slick.
    Safe for all portals, gear boxes and transmissions.
    He explains it all in a video on there website. Same thing your interested in doing here!

    Yeah I seen that earlier on the HW site the gear butter. I ran WS2 and know that it works for a whole lot less money then gear butter. Pretty sure the WS2 is equal or better then the gear butter. Wouldn't be surprised if it doesn't have tungsten disulfide in the gear butter.

    I have changed my rear a number of times with the recommended GL5 80w90 and the manual never mentions any modifiers for it. Its filled with GL4 initially which is harder to find. The GL5 is backwards compatible to it by all spec's comparing the two.

    Maybe the X2 spec has changed but I don't see why Yamaha would have built a different rear end as the rest of the power train is the same apart from the engine.

    Yeah kdt1970 that's why I've used it so far.
    3 oil changes in 1k miles and the oil has always looked new.
