I can shift into reverse and 'high' gear beautifully, but I can't get the UTV to go into low. I hired a mechanic to change the belt, and clean the clutches. When it came back 'low' gear no longer worked.

I tried to change I've tried replacing fan gears  https://www.amazon.com/gp/product/B08V97JZL5/ref=ppx_yo_dt_b_search_asin_title?ie=UTF8&psc=1 that were worn down, and it shifts better but, didn't fix the low gear problem. I can't shift into low with the engine off either. It indicates that it's in low gear, but I hear what sounds like something spinning in the middle of the UTV. 

It seems like the mechanic didn't know what he was doing. Never even mentioned it to me that 'Low' didn't work, until I went to use the

Chris, thought I'd throw this out to will until more informed members help you out. There are some here that have more knowledge on these things than Myself. I own a 2016 MSU 800. In 7 yrs I have very few problems with mine. Mainly brake pads which I consider a wear item and wheels bearings a couple times. Mine has sealed wheel bearings as opposed to roller bearings that can be maintained, the only maintenance of sealed bearings is run them until they wear out and replace them!!

  On me machine if it gets to where it doesn't shift well it's usually the adjustment on the shifting linkage, which in my opinion is quite touchy, therefore it doesn't take much for it to get out of adjustment.

      Hisun Axis 500 Problems - Hesitation, struggles to go up incline, and low speed regardless of gear range
      By AlphaSerenity
      Hello,
      Before I invest $10k+ into a brand new UTV for the farm, I want to get my feet wet with a fixer upper and learn the mechanical side of things. I acquired a 2022 Hisun Axis 500 (Lowes-specific model) from an auction for $500. It has only 200 hours and 120 miles on the engine. It looks like the previous owner used it for ranch work and didn't drive it on trails, deep water/mud, or anything too crazy.
      While it runs and moves, it has some problems. It struggles to accelerate up any incline in high and low range and sometimes stalls when I let off of the throttle or change gears. When I apply throttle in neutral, it sounds like it is struggling for fuel/air and pops. When I decelerate, there is a grinding sound coming from the clutch, which I've read to be related to the one way bearing and is semi-common. The last thing I've observed is sometimes the speedometer display sometimes will show a much higher value for a few seconds after barely touching the throttle. Based on the documentation, if a problem is detected from the sensors, the instrument panel display should have an error code rendered on the screen in place of the time, but this isn't happening. Here is a video showing some of these issues (engine is exposed with console removed):

      Here is another video of the clutches in action:
       
      I've done some research, but information on this specific unit and sister units is limited. There does seem to be transmission and clutch issues reported. I still need to check into the head gaskets. I don't have the equipment to test compression right now, but I do plan on ordering what is needed soon. I do have an order in place for some cables to read the diagnostics from the computer. There is a shop two hours away from me that works on Hisun products, but I am hoping the problem can be identified and is something within my ability to handle. Below is what I've already investigated.  I am leaning towards the primary clutch needing replacement right now.
      After getting it home and unloaded, I did the following maintenance/checks to it prior to operating it further:
      Changed the engine/clutch oil (and filter) and gear oils using manufacture recommended viscosity Changed the air filter and checked for cracks in the air intake flow. Verified good suction. Cleaned the throttle body Changed the spark plug and verified the gap was within spec (0.6-0.7mm) Changed the coil and coil wire Changed the fuel lines, fuel injector, and verified the fuel pump was outputting the correct initial prime pressure for ignition and continuous pressure after ignition. Also completely emptied the fuel tank and made sure octane 91+ fuel is being used per manufacturer specs. Ran seafoam through system too. Cleaned the spark arrester and verified no cracks or gaps in the exhaust flow Changed out the O2 sensor Checked all wired connections to ensure they were secured and no breaks were visible Checked the belt for tightness and for any signs of wear and tear Verified 4WD and the differential lock function as expected - still hesitates and struggles uphill Verified the fan gears in the shifter are not corroded and working as expected ECU was reset after replacing sensors and fuel-related parts

      UTV Odes Ravager 1000cc - Strange noise from the back
      By Ermd ttk
      Hello friends,
      I got my ODES Ravager UTV yesterday and after a couple of hours of driving when I go downhill I heard a strange loud noise a couple of times, like a gear skipping or maybe something from the differential.
      It doesn't always happen and when it does it is heard for a few seconds and then it goes away and everything works normally, I'm worried if there could be some major malfunction or what could be the problem if someone can help me?
      Thanks a lot.

      "R" light will not go out when the UVT is in any other gear. Is this an issue?
      By Steve B
      My "R" light on the dash will not go out when I take the UTV out of reverse and put it into any other gear. Is this just the light switch issue or will this effect engine performance in the other gears?

      2021 Coleman UT400 - Transmission fluid change
      By AlaskaTrail
      Hi All,
      New to UTVs and recently accuired a ut400 from our local Alaska Commercial Co. and had a questions regarding the transmission fluid. I have had a squeeling noise, sounds like a teapot, that recently started after being driven for a few minutes. The manual says to change the fluid at 500 miles, so I was thinking maybe its just time for this to be changed. Other then that I cannot find any information regarding the type used. While reading through these forums, I seen someone put that the transmission is lubricated with the engine oil. Is this true? If not what should I be using and where can I find the information to change it out? Any input on this would be greatly appretiated!
      Thanks in advance

      2013 UT 500 won't go into reverse.
      By lonerider98
      At the end of last year my Coleman UT 500 will not go into reverse. I can hold it over toward the reverse to move it nut it won't lock into reverse. Anyone have this problem? Winter is just about over and going to have to get this resolved. Thank You!
