2009 Hisun 700.
Well, back to square one.
I've been doing this rebuild since Jan. 2021. MANY new parts and fixes and re-starts and working/then broke/then working/then broke... and on and on. Last week I had a good ride, about 18 miles. Ran great. Parked in the garage for 2 days and then the exact same problem as last time-- Cranks and cranks, about 6 or 8 times, and then click: nothing. I get one click and a red warning light on the dash but it's too small and doesn't say what it is. It's not the battery: it's fully charged. Had it on a charger overnight afterward and still getting one click. It's like the starter is stuck or the engine is seized. The last time it happened I took it to a guy who's rebuilt many of these and he found the starter was full of oil! Black oil. He said it was black 'cause it got cooked trying to crank. Put in a new starter and he did all kinds of adjustments and between him and the neighbor it was running great. Now it's stuck again. I'll pull the starter when I calm down....
One of the MANY new parts we threw at it was a new battery. it's got plenty of power, 350 cold cranking amps. Is it possible to have TOO heavy a battery?
But has ANYONE run into this? 🙁

Well the good news is, the starter's not full of oil this time. Bad news is, the connection point is melted inside. I'm thinking something jammed inside the crankcase and the started was trying to turn against the jam and melted.

Yup--- Did that today. It turns easily in one direction and slow-but-sure in the opposite direction: compression. But it does move so it's not seized.

I fished a piece of a ball cage out of the oil filler spout several months ago and I've always felt that there must be other metal junk down in the case. I had a guy working on it but he didn't have an indoor place to take the crankcase apart to check. He did get it all timed and valves set right and it ran good once or twice. The last ride was about 18 miles with no problems. Then it sat in the garage for 2 days and wouldn't start: just cranked and cranked. Until it locked up, I guess from the starter melting. But I didn't crank long, just 6 or 8 normal cranks and was about to give up but it locked and smoked. So ... there it sits.

Interesting, the rest of the cage bearing must be in the case. Not good! Did you drain oil from engine when you found cage in spout? If not, do so and meticulously inspect oil for foreign matter.

Did you turn motor over several revolutions by hand? Did you hear or feel any grinding or resistance? Remove spark plugs prior to test.

 

What is voltage at signal wire of starter when turning key to start position.

You may have two issues, electrical and mechanical.

Oil change--- I didn't. It went to a mechanic and he did all kinds of work on valves, etc., had the valve cover off and did some things... (I know Jack about engines so I leave it to more knowledgeable people).  He did say he didn't see anything in the oil when he drained it. I had told him about the ball cage and he didn't find any debris or metal shavings . I don't know for sure if he emptied out the oil or not. I plan to borrow a neighbor's magnet/stick today and fish it down in the oil spout and see if it brings anything up.

I will try again to turn it with the plug out and try and do several revolutions.  I'll check voltage, too.

Thanks.

      Considering buying a 2021 1500 coleman
      By Rusmis91
      I’ve never been around Coleman Utv machines. Do they have a good reputation, durable dependability. Could you compare them to yamaha rhinos or Polaris ranger
       
      thanks in advance

      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  
       
      Thanks!

      Hisun Sector e1 Battery replacement: any tips?
      By didgeridoo
      Hello, All!  I've decided to replace the traction batteries in my 2018 Sector E1 with a 48V Lithium set. They may be expensive, but I figure the Discovery Dry Cell are, too. I am not looking for the max driving range, as I have never received near the brochured range to begin with, but a good mix of charge/ get work done/ charge is what I am expecting.
      I have settled on the 48V EAGL kit from bigbattery dot com. Each battery pack provides 30Ah. The kit ships with a charger, as well. The packs would be physically connected in parallel (using a busbar) to one another, maintaining the 48V voltage, but together would be able to provide the amp draw the buggy pulls when going up hill or towing a rake (rated 320 max continuous Amps). This is in comparison to the serial connection the eight 6V lead batteries. Each of the EAGL batteries looks to have its own BMS; am I correct in thinking I will have to use their included charger rather than (simply) changing the onboard charger to lithium mode? The chemistry of the pack is LiFe PO4, for what it's worth.  I haven't torn anything apart yet (to diagram), so  I am not sure how the dash will interpret the AMP draw, but the kit I am looking at includes a dash mounted charge indicator.
      If anyone has completed a similar conversion, do you have any tips? Specifically, how did you remove the original batteries, and how did you secure the new ones? I am guessing that almost any change from the stock batteries would involve at least some modifications. Any tips would be appreciated, especially things I may have failed to consider. Thanks!

      Is Your HISUN Loud?
      By HISUN Sector 750 EPS Failu
      "Mrs. Smith" doesn't like how loud our Sector 750 is.  On a HISUN forum someone said the same thing about his 750.  I haven't given it much thought because I've been more focused on stuff that has broken.
      So, I used my decibel meter to check ours out.  4000 RPM, Low gear, under 20 MPH . . . . 97 decibels.  That's above most ordinances, even state boat noise limits.
      AI Overview Ninety-seven (97) decibels is considered very loud and dangerous to hearing with prolonged exposure, roughly equivalent to a newspaper press, a loud nightclub, or a snowmobile. At this level, damage can occur after just 30 minutes, necessitating hearing protection

      Best place to find info on Hisun or Massimo UTV's
      By Eman85
      I have been searching and can't find much info on these units. Pretty surprising as every other thing I own I find a lot of info on. Researching for tech info and such it's like no one owns any of these yet I see them everywhere.
