I have a 2021 Massimo T-Boss 550 which now has a crack in the rear gearcase. A few weeks ago during my usual fluid checks I noticed that the gear oil was very low and there was an oil film on the outside of the case on the side where the plug is. I topped up and cleaned it up. I assumed the the bolt was not sealing properly so I ran it as usual and same thing again and again. So then I was thinking that maybe I need a new washer or something. I cleaned the outside of the casing and was about to top up the oil when low and behold.......I noticed a crack across the top right side. OMG, this thing is only a year old. Any ideas out there on how this would happen and most importantly....how can I fix it?

Any advice would be appreciated because as we all know on this forum it is hard to get shops to work on these wonderful machines. And if I need parts, wish me the best of luck.

The way they are set up I think you can rule out being over-filled.  Sounds like it has still been running so something cracking it from the inside doesn't sound plausible either.  My guess is a weak spot in the case when manufactured.  Other than a replacement, I'd probably opt for Industrial Strength JB Weld (depending on how big the crack is).  I've seen guys fix automotive tranny's with that stuff.

Thank you for the response TapBoss. Funny that you mentioned JB Weld, I watched a dozen Youtube videos on it this weekend and went out to buy some yesterday. The crack is on the top so hopefully this patch will keep me going for quite awhile. It kinda looks like there was a crack in the manufacturing die; not sure if this thing is forged or cast but it is a long crack and parts of it protrude outward

      Has anyone purchased a rear differential from Alibaba, they want $432.00 for diff and $35.00 for shipping. This would be a great deal if I can trust them any thoughts?

      2021 Axis 500 4 month Review
      By mac66
      I bought a used 2021 Axis 500 last April.  Low mileage and got it for considerably less than what they go for new.
      The first thing I did was change the oil/fluids and also put a new drive belt on it.  The only other thing I did to it was add a rear vinyl window that zips open and rolls up to keep the weather off.
      I used it on my 52 acre property to check trail cameras, service the food plots, haul fertilizer, seed etc etc. It's has a good size bed and is not too big or small.  It has worked well as a utility vehicle. 
      Other than using on the trails working around the property I haven't used it much off road...at least until last weekend when I went on 74 mile group ride around the county. In my state it's legal to ride on any road that's not a state or federal highway. The group started in town, rode about 30 miles on back roads to the state ORV trail system. Then did about 20 miles on the trails and then headed back via back roads to town.   
      It had rained for 2 days straight prior, so the trails were one mud hole after another.  It was very challenging.
      The good...
      -It worked fine, never had any kind of issue with it since I bought it.
      -It kept up with more expensive machines on the trails. I was the only one with a CCC (Cheap Chinese Crap) machine.
      -Fairly comfortable to drive.
      -The roof, windshield and rear window kept most of the rain off when it started raining in the afternoon.
      -Okay, I cheated. I peeled off the AXIS 500 stickers on each side. Everybody in the group assumed I had a Rhino. They didn't ask, I didn't tell.
      The not so good...
      -The horsepower rating on the 500-cc engine is 24 hp but it seemed underpowered. While I could go about 35 mph with the pedal to the metal on pavement and hard packed dirt roads the best I could do on loose packed roads was 27 mph. I had trouble keeping up with the others in the group.  It also bogs down on inclines in high gear.  On the other hand, in low gear and 4wd I didn't have any problems going through mud or sand or up hills.
      -It is LOUD! Had to wear shooting earmuffs to keep my ears from ringing while riding. Going to have to address that.
      Overall Impression...
      I was impressed with it on the trails, and it is a good utility vehicle for working around the property. Considering what I paid for it I am very happy with its performance.

      2021 Hisun Sector 750 Primary Clutches
      By FDWT9956
      I am putting a new primary and secondary clutch into a 2021 Sector 750. It is rarely used, only 350 miles, brought brand new and lost the CVT belt and I can't figure out why. In the first picture is the primary I removed.

      I received the new primary and it has a retaining ring around the outer edge. Does this make a difference?

      Snow Blade for Coleman Outfitter 550?
      By Alien10
      I'm thinking of buying a snow blade for my Coleman Outfitter 550 (Hisun with Coleman stickers).
      Has anyone purchased a snow blade that can offer the make and model they bought and any comments, pros  cons etc.?
      Not 100% sure I'm going to buy, as the selection of blades for this model seems a bit thin on line. 
      Thoughts and comments welcomed.
      Thanks in advance.
