Hisun 400 UTV leak from side of transmission


Davo

Recommended Posts

I have a Hisun 400 UTV that has developed a sneaky oil leak from the end of the black plastic thing protruding from the side of what I think is the transmission on the driver’s side. Looking for any guidance or advice as to what this thing is and whether it’s fixable.

Apparently at some time it was the speed sensor--I found this part on AliExpress (who I wouldn't buy from if they were the last vendor on earth):

However on newer models like my 2020 and apparently the OP's 2012 the active speed sensor is on the rear reducer and there's that crappy plastic cover on the crankcase.

I think on the 2012 the reducer mounts with the "flat" side on the right and the sensor is on the left--don't know when or why it was "flipped", but it seems to coincide with the engine being changed to the rear slanting cylinder.

a 2020 model from Coleman's site:

yup--an undated, I think pre-2018 HS400:

I'd pull the plug out, make sure it's intact, clean it well and put it back together with a good dose of Permatex's Ultra-Grey gasket maker (best I've ever used--the crankcae on my 2003 Suzi Burgman 400 was reassembled with that 5 years and 26k  miles ago) --if it is cracked use some of JB Weld' high temp stuff to fix it:

      hello everyone, i just joined this forum to try my luck, few days ago i bought an old (dont know exactly), 2011/14 hi sun 500cc ""carburated"",  was not running at the time, but i fell was a good deal and decided it to bring it home to play with it, this is the issue, i bought and installed a new carb, and pump, i repositioned the battery location and upgraded to a "car batt", reconnected the fuel lines and started it, but it only runs with the choke ON, i checked the bowl, it does have fuel,but for some reason wont inject it to run, i came across a video that say that ""the body small tank had to be connected for the cart to run" (was deleted when bought), sure enough i got it to run sporadically , but the so called ""small body tank'' often runs out of fuel and wont refill itself , i had to couple times do it manually, so how does that small tank works ?..what does it do?..and why if  bypass it , the cart wont start?....any help?..thanks so much!!!

      Howdy Everyone,
      New member looking forward to learning and sharing more about UTVs. I have a 2019 Coleman Outfitter with the Hisun 550 engine. Does anyone know what Code Scanner will work with it ?

      I'm working on a Coleman UTV 400 that has a rough idle, owner has had it for about a year. When I say it has a rough idle, it doesn't have the continuous smooth running sound. At times you can hear it kinda skip, sputter, or like the RPM has fallen (RPM stay constant according to the gauge) It's not as bad as it was after I replaced the fuel filter and fuel injector (both are Chiki) not sure if that is a quality brand at this point. Checked the spark plug, it was a little foul, but not too bad. (Since the engine is still idling bad I'm going to replace that) Cleaned the throttle body making sure the carbon and soot has been removed, and the air-filter has been cleaned. New fuel is being used so it's not old or been standing. They did tell me that they were using non-ethanol fuel, not sure if that would be causing the issue. Next two things I can think of that maybe the issue is the O2 sensor or the valves need adjusting.
      Thoughts and suggestions? Thanks in advance.
