I just found this on another messageboard. I wonder if the Commando is having the same problems as the Trooper.

Post subject: New style diffs to replace in 2006 CommandoPosted:

Posts: 1 Just rec'd 2 new style rear diffs from joyner to replace in the 2006 650 Commando. Need to know how to take the cv cups off old style rear diff that need to be installed in new diffs. Is there any special tools needed or do you have to hold your mouth just right??!!! Any help will be much appreciated. Thanks much

I think your find that the Commando gears in the front and rear diffs where not meshing correctly. In other words one gear would ride on the top of the teeth instead off fitting the gap fully. The result was the tips of the teeth snapped off. Not too dissimilar, different problems with same result. All new Commando from the middle of last year have correctly shimmed diffs.

Cheers Mike.

Just put a new diff in mine. when I opened up my diff to check for sheared bolts like Kinarfi had, I found a completely mis-shimmed differential and I could see that the pinion gear wasn't correct, In my case the pinion gear was not only too far away from the ring gear but was also pushed in too far torwards the center of the ring gear. This looks to me like it's causing the tips of the pinion to take more then it's fair share of the stress and thus ending up fracturing chips off. I think proper alignment of the pinion gear axeually in relation to the ring gear is even more damaging then improper gear tooth clearance. My teeth were chipped, thus the new differential. Fortunately, I purchased the 3yr extended warranty just as it came available and they covered it. Joyner got a diff out and I received it in 1 day.

Lenny,

Did you open up the new diff?

Definitely did. Found the same problems. I installed my diff kit in it giving it much stronger bolts and better security from bolts comming loose. I also re-shimmed it for clearance and proper pinion to ring gear alignment. Real happy with how it came out. See my post under Diff blowup.

Lenny, it was my understanding that the Commando diff problems were just the mis-shimmed teeth on the gears. I just wonder that in your case that caused the gears to walk away from their settings slightly making them to far away from the ring rear if that is possiable. I don't think that happened with the Commandos, maybe they snapped because the strength was less than the Troopers. Anylizer might have the inside word with that issue.

Cheers Mike.

I would really like to see Joyner step up and take care of the Diff problems. By using bolts of poor quality and the diffs not being made correctly aren't they responsible? Ours is parked until we get Lennys fix it kit. I think that this is a major problem and the second one (the drive-line was the first) in the last year that is either poor workmanship or lack of quality in parts and design. All I can say is thanks to Lenny for all his hard work in keeping all of us on the road.

      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):
      https://www.youtube.com/watch?v=FFAkO5TaGps
       
      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!

      Hy (pronounce he), just bought a Hisun Sector E1.

      trying to finish assembly "new" 2021 Coleman ut 400
      By buckrub
      Hey guys! Newbie here. I'm an old man who's better with plowing a mule (4-legged kind) than these newfangled beasts. I, and a friend of mine, just bought new Coleman sxs and are having to finish the assembly. I've been reading on this site and I'm falling on the mercy of you experts. The only way I'm an expert is that an "ex" is a has been, and a spurt is a drip under pressure. LOL First off, the 2 buggies have no ignition switches. They seem to mount on the dash, not the opening in the steering wheel shaft cover, so we ordered new ones that are supposed to fit. They are 8 inches long, and have a 4-wired white plugin which is slightly rectangled when looking at the end of the plug. The trouble is there's nothing to plug into. There is a three-wire grey plug close enough to reach the four-wire plug, but of course, they are not compatible. 
      Secondly, the blinker, light, ect. unit on steering wheel just spins around when touched. I see no way in heaven or earth to secure it. I've looked at a diagram on the Powersports site, but can't detect how it mounted. Fellows I'd be so grateful for any help with this. Me and my mule will even plow your garden for free, for your help. LOL

      Bennche 700 EFI Bighorn New Fuel pump not working
      By Nathon S.
      I have a Bennche 700 EFI Bighorn. I’ve recently been unable to get it to start. After a little troubleshooting I realized my fuel pump was not pumping fuel. This weekend I emptied the gas and replaced it with new. I replaced the fuel pump, fuel filter and fuel injector. I also replaced the battery, spark plug and made sure all my fuses and relays were good. I have confirmed that the float on the fuel pump is not obstructed. The UTV is about 12 years old and has less than 100 hours on it. It has not run in over a year.  Not sure whats going on?!? After doing a little reading I'm leaning towards it being an issue with the ECU or perhaps a faulty wire in the wiring harness. Anyone have any ideas on where to start looking or what I could be dealing with? Any help is appreciated, thanks in advance!
