This may apply to other models as well, but mine is a 2022 Sector 750.  My brakes were squealing irritatingly from day one, so I inspected all the brakes in the first 500 km and found that one of my parking brake pads had fallen off the backing plate, possibly from the factory.  I thought this was an aberration until recently, when one of the factory pads fell off the left front caliper. Basically, the friction pad delaminated from its backing plate in both cases.  Fortunately, it happened at low speed and my wife felt the pedal lurch toward the floor, knowing something had occurred.  I replaced ALL the pads, which still had plenty of wear life left, because it's clear that there is some kind of manufacturing defect with these factory pads.  So if your brakes are squealing, check all the pads.  Or just check them to be sure -- they still function with the backing plate squeezing against the rotor.  This can be a dangerous failure.

      2018 cub cadet 750 challenger clutch issues?
      By esmarkey
      Hi, I purchased a used Cub Cadet 750 Challenger that seemed like the belt was slipping so I put a new belt in.  It still acts like the belt is slipping but now I am thinking it is the clutch? 
      What is the best way to remedy this problem? 
      Can the clutch be rebuilt?
      Are there aftermarket clutches available?

      MSU 500 Fuel Pump Ground
      By Kierobi
      Have a MSU 500 that we got from my wife's uncle a while back. We've had it running and hauling around the property but it stopped a few months ago after what I thought was running out of gas and I'm just getting to looking into it. 
      Had fuel to the injector but nothing coming out the injector so swapped with new injector and installed inline filter in the supply hose from fuel pump. Tried again and still nothing but noticed this time that I can't hear the fuel pump priming. 
      Pulled off the electrical connection and I'm getting 12V to the fuel pump but it won't run. Put it on a test bench and got it to run so put test lamp between +ve and -ve terminals on the connector and nothing. Checked against the passenger seat securing post and get a light. 
      Tried chasing the wire back and think that the ground is through the ECU but not 100% sure. Can someone confirm for me? And if it is through the ECU, is the ECU just grounded against the frame or is it wired through to the battery?
      Thanks in advance and hope this all make sense!

Can I use your typical vehicle code reader or do I need to download something on a laptop or PC???

      750 Sector Rear Diff Swap
      By CarlB
      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.

      Fuel injector replacement Massimo 500
      By Eman85
      Pulled fuel injector to see if I could clean it or if it's stuck open. Had a slide on clip that was really tough to get off. Don't see how the clip is supposed to lock into the plastic part that the injector slides into. Any videos or pics of injector replacement?
