     I’m pretty sure this has been an ongoing issue even before I got it. Towards the front of the crankcase, right of driveshaft coming out I noted a lot of oil buildup. I cleaned it up really to see if I could identify where it was coming from. It looks like there’s a seam where the two sides meet and that’s where leak is originating from. 
 

     From what I find in the service manual it doesn’t look like there’s a gasket here. So would anyone know how this seam prevents oil leakage? The next question is how would you correct this leak? I’ve read where you don’t want to use oil leak stopper as that will most likely cause slippage on your wet clutch. Any thoughts? 
 

Thanks, Harrison

 since they didn't use a gasket most likely they used a RTV sealant (liquid gasket)

The only solution i can think of is to take it apart, clean both gasket surfaces with brake clean and Rubbing alcohol works good at removing that stuff. and a razor blade is good for scraping paper or RTV gasket off.

I prefer to use Permatex Ultra black sealer. good up to 500 degrees F, https://www.permatex.com/products/gasketing/ultra-series-gasket-makers/permatex-ultra-black-maximum-oil-resistance-rtv-silicone-gasket-maker-4/

And for any surface that comes in contact with Gear oil i use https://www.permatex.com/products/gasketing/gasket-makers/permatex-gear-oil-rtv-gasket-maker/?locale=en_us

Oil leak is the one thing mine never had.. knock on wood... But I agree, separate the two , clean them up and use hi-temp RTV is the only solution.. unless the bolts are loose . might check that first

looking back at that picture again, it looks like someone put 3 allen head bolts in it. then above you can see a regular Hex head, weird.

you might check to be sure they're tight.

      I'm looking to purchase a 2015 Massimo 550 that might have an issue with it's throttle position sensor.   
      From the fella selling this UTV, he claims its to set the idle on fuel injection because the engine will not stay idle or when it starts sometimes it idles too high.
      My Question if anyone had any issues with their Massimo 550 and if it was actually the TPS or something else that would allow the machine to idle correctly.
      Thanks!

      Hi I'm about to order parts to do a bunch of work on my Massimo. Does anyone know if there's a difference in the top end kit {piston, Cylinder, Rings, Gaskets, Piston Pin} if it has a carb or EFI? I'm EFI and I think some came with a carb so I thought i'd ask before making a mistake...
      Thanks Jerr

      I have a 2021 Massimo T-Boss 410 and it needs the cv boots replaced.  Has anyone had to replace the boots on their T-Boss?  Does anyone know where to get replacement boots?  Are there boots for other ATV/UTVs that will fit?  The Massimo parts site only sells the entire axles.  Thanks

      Picked up an essentially new 2022 UT400 with 9 miles on it.  Decided to change the oil because it's probably never been done.  Pulled the dipstick and noticed it was overfull then went and pulled the drain plug and took off the filter and it was like brown water running out.  What should I start checking?
