So i have a 2018 Hisun Sector 750 Crew and while driving the noise level is outrageous.  I want to find a way to decrease the decibel level, so does anyone have any ideas!!! i was thinking about installing foam on the roof enclosure and possibly putting something around the engine bay area.  I have not found any companies that makes a suppressor for the muffler...Any help would be appreciated.  thank you

I have a diesel mule that has the intake in the rops bar. It's loud also. A back window tamed the noise to a tolerable level. Since I'm not familiar with your machine, it might not be helpful. But insulating, and deflecting that noisemaker away from the cab would be the way to approach this.

Just a shot in the dark here. But I see those black truck bedliners, on the side of the road that've blown out of a truck. That stuff would be an excellent material to fabricate what you've described.

I used this for good effect - self sticking with aluminum foil on exposed side.

      2017 Cub Cadet Challenger 750 hisun junk motor
      By hisun junk
      As I tried to do a conversion with the Yamaha 660 motor, I realized the 660 was never fuel injected so it would not work for the fuel injected hisun motor swap. But the good thing is the hisun 750 motor is a clone of the 660 Yamaha but with the components for the fuel injection (cam/crank position sensor). So that left me with a new rebuilt Yamaha 660 and still a broke 750 hisun motor. I took apart 750 think the timing chain had broke from all that I've heard about these motors. The chain was not broke, but just off cam and crank gears! The chain tensioner was at fault!  I've ordered Yamaha 660 replacement parts, chain, two exhaust valves (which got bent when chain came off while motor was spinning) and seals. The piston has 2 little nicks where it had hit valves but no damage otherwise. The head is being redone at the machine shop and I'll be putting it back together in the next couple of weeks. Also I finally tracked down a Service Manual with all the info on the 550/750 Challenger.

      Help needed, Anyone recognize where this Internally Threaded Bolt belongs?
      By SouthernGypsy
      We have a 2018 Cub Cadet Challenger 400 and I found this Internally Threaded Bolt with a 10mm head size laying in the floor of the shop bay here on our ranch where we park the Cub Cadet.
      Trying to figure out where it belongs...

      Hisun Vector E1 - Gear oils
      By Justine
      I've had a Hisun Vector E1 for just a bit longer than is required for me to do some maintenance. While it's well-overdue, it only drives 1.5km a few times each week on a fairly decent gravel road (to the letterbox), and it has worked really well right from the get-go.
      Looking at the manual it states that I need to use SAE80 API GL-4 Hypoid Gear Oil for the Main gear Case, and SAE80 API GL-5 Hypoid Gear Oil for the Front gear Case - unfortunately i can't find either of those online here in Australia. Plenty of options that look close, but, as someone who has never driven any vehicle before, I want to use the right thing and it's a tad confusing.
      My question: Since there are no oils that are bang on SAE80 (they all seem to cover a range) would Liqui Moly Hypoid GL4 Gear Oil 80W-90  & Motorex Hypoid GL-5 Gear Oil 80W90 - be ok to use? (Or any other suggestions of what I might be able to purchase online in Australia) And would I have to drain out any existing oil from both gear cases?
      This is a whole new world for me and  being able to find exactly what is specified in the manual hasn't made this easy!

      Hopefully someone else will buy a UT10X and join in.
