My father-in-law has a Hisun 750.  It has started to not change gears while running.  He can turn it off, change gears, then restart and it will change.  I thought it might have something to do with the brake but can’t find any info.  Thanks in advance for any info.

How many rpms? Mine does this when idling is high. When it got warm I had to change the oil for the 5w40 winter to the 15w 40 for the summer.

There is a safety switch (I think) that is supposed to prevent you from shifting gears without having you foot on the brake. That switch is also supposed to prevent you from starting the machine in gear without having you foot on the brake. I'll take a quick look and see if I can locate where it is. I think it is by the brake light switch at the base of the brake pedal. 

Kinda like the switch that kill the engine of a riding mower if you get off the seat with the blades engaged or in gear and fall off.

Well as usual I'm wrong. There is a pin that prevents it going into reverse unless the brake is applied. But didn't see anything about a separate switch on brake pedal for shifting. Could be the brake light switch has multiple purpose.  I'd check it anyway just to make sure. And check the shift linkage. See pics below.

Good luck.

BUCK,

I have an Axis 500. I have no shift issues. Haven't changed anything with brake pedals.

With engine running, I can go 

N to HI or LO with no brake

LO to HI or N with no brake.

LO, HI, or N to R have to have brake.

R to N, HI or LO no brake.

Start in any position with no brake.

Don't shift to any gear rolling.

I'd check the linkage on your father-in-law's machine.

He said he checked the linkage.

Since the linkage seems to be good.

As T Fox asked, what is the RPM when trying to shift into gear while running.

High RPM could be an issue. And at high RPM the clutch would be trying to engage/engaged also. Putting pressure on the shaft attached to the primary sheave. Trying to move the CVT belt. Making the secondary sheave engage. And the secondary sheave is attached to the shaft that turns gears in the transmission.

And the clutch is in an oil bath also.

      Just wondering if mine is the only one that’s seems very loud while driving. It just seems louder that other brands I’m use to. I guess you get what you pay for I’m assuming.

      I am considering a Hisun 550 for tooling around the farm> I have a Kawasaki Teryx 4 and deeply disappointed at the difficulty of getting to the engine and belt for repairs. I would like some feedback on the Hisun's reliability and ease of access to work on. Thanks.

      I am putting a new primary and secondary clutch into a 2021 Sector 750. It is rarely used, only 350 miles, brought brand new and lost the CVT belt and I can't figure out why. In the first picture is the primary I removed.

      I received the new primary and it has a retaining ring around the outer edge. Does this make a difference?

      Recently purchased 2nd hand not going Crossfire GT400 (Australian branded name?) 2020 model.  Has some issues what would be the best forum to pose questions.
      Thanks

      My father-in-laws 750 hisun will not change gears unless he completely turns the motor off then shifts.  I thought it might be a brake problem but he thought clutch.  He took it to a jackleg down the road and he basically charged him $300 and did not fix a thing.  Any ideas would be useful because he really can’t afford throwing money at it.
