HISUN Sector 750 EPS Failu

Shouldn't have to . . . . and for all the neighbors, too!!!???

Put a DB app on your phone, and find out. It's free.

My phone has the DB app, so I set it on the passenger seat and went for a ride. 4000 RPM, 20 MPH. 101 decibels! That violates most noise ordinances.

Maybe on a day I'm not replacing the driveshaft! 😝

"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

Sometimes it is a long route to get to where you need to get to. The current Tech Team asked me to send a picture of the current coupler AND BOOT. Hmmmmm! Let me go look, Yup, no boot, the dust cover for the coupler. It never had a boot, from the factory. Here's a picture of it when I took it off a year ago. NO BOOT. A year ago I replace the coupler and put the driveshaft back on exactly the way it came off.

That was a year ago and I turned out to be the local repair facility. It was a booger to replace the $20 driveshaft coupler. It has failed again. Just 142.5 hours, and we are 70-year-olds, not driving over 20 MPH. I've reached out to the HISUN Tech Team again. The first time around they knew it was going to be the coupler, since it is successfully engineered to fail first, before the differential. Annual driveshaft repair, twice every 100 hours, was not in any of the advertising brochures!

I thought I had my own thread when the driveshaft coupler failed a year ago, but I guess not. It has failed again. Only 142.5 hours. Two old people operating at 20 MPH. That's pretty sad. I've reached out to the folks at HISUN again, to see if they are still there.

Totally agree. My HISUN Sector 750 has one, and I hook up a battery maintainer in the Winter months. Works just fine. I have no problem with the digital clock and hour meter on the display. They work fine, too.

That's exactly what i recommended. Like I said, those using it are used to the clutch slipping (they are clueless), so hopefully it won't get worse if we switch oil, twice.

That pretty much applies to the one I'm referring to. This clutch is slipping, but still grabbing. It's a machine that's used every day in golf course maintenance. I don't believe they've gotten around to switching out to JASO MA2.

I posted a link to a HISUN VIN letter to the NHTSA, but it's hidden because it's a link. Use google if it doesn't appear.
