I have a 2022 Hisun 750 Sector which comes with a locked rear differential. Was wondering if it would be possible to install an unlocking differential. I see that there are some Hisun made machines that come with the unlocking rear diff, such as Cub Cadet Challenger, some of the Massimos, and probably others. My concern is whether these would be a direct bolt on, using the original axles, drive shaft, and of course matching gear ratio. I've tried to match up part numbers but it seems every brand has their own number system even for parts that I know are identical. If anyone has ever done this swap or has any information about the whether these unlocking rear diffs are comparable to the Sector, I'd appreciate your input.
My 2022 Coleman/Hisun UTV 400 steering shaft has a couple of U-joints and angles to help get it down from the steering column to the rack. Today, my son who drives it most came in and said that it wouldn't steer and that he could turn the steering wheel but it doesn't turn the wheels I investigated and noticed that the bolt that clamps down the upper part of the steering shaft onto the lower one before the first u-joint in the steering shaft had fallen out. We haven't been able to find it, so I wanted to see what size and thread, bolt I should get to fix it?
When I am moving forward on my Hisun 500, the motor accellerates up and down while I have my foot on the gas pedal. It also is not idling very well. Both symptons appeared at about the same time. What should I look for? Thanks.
Bought a Coleman 400 UTV (pretty much a Hisun), the previous owner tried to replace the timing chain, couldn't time it properly and sold it to me. After some hours I figured out how the timing all is supposed to be set (I think/hope) and as I am reassembling, I noticed that the water pump gear was awfully hard to spin. I held the gear with my hand and spun off the impeller. I checked the bearing, spins great no obvious issues noticed other than this o-ring which seems to be out of place? When I remove this o-ring and reassemble the WP, it seems to spin nice and easy without a drag. I looked up the service manual (although very inaccurate info there often) and don't see this o-ring present. Am I missing something here or what? Any input?
This is not easy to access once the engine is back in the machine so would like to avoid having to deal with this if it becomes a problem.
