2019 Massimo T-Boss 410 How To Unlock Differential


Locking Diff

  • Alex changed the title to 2019 Massimo T-Boss 410 How To Unlock Differential

Are we talking about the front or rear differential? The front diff is the one that locks when the 4X4 is engaged. At least, that's what the tech said. I don't know about the rear diff. I have downloaded both the owner's manual and the parts manual, but I don't remember seeing anything about the rear diff.

  They have told me that the rear differential is always locked and it's the front one that locks when put in 4wd. It sure makes it hard to turn on wet grass, gravel or concrete.  Not a good design, you have to give plenty of gas to get it to go while turning  going slow. Other than that it seems like a well constructed unit,, it does what I need. It could use power point to plug in my sprayer.

So, unlike a limited slip differential such as in the automotive industry,  it's locked always? Yeah, I can see how that would make it more difficult to turn. You would think the engineers would have taken that into consideration during the design phase. I have used mine for some yard work, and I can see what you mean. It doesn't have a very tight turning radius. Great for straight line traction, though.

I'm running the risk of telling you stuff you already know.  Your Massimo (made by Hisun) and the Bennche have similar 4WD/Lock systems.  In 2WD, the rear diff can't be locked (shouldn't be unless there's a problem with the actuator).  You can select 2WD or 4WD unlocked differentials.  There's a lever that covers your lock/unlock select switch.  You rotate if you're in 4WD to uncover the lock/unlock selector.  This switch locks both front and rear differentials; not independently selectable.  Apparently, you can't lock just the rear diff or just the front diff.  If you can, jack up the rear of your machine and select 2WD, neutral transmission.  Turn one of the rear wheels; the other wheel should rotate in the opposite direction if unlocked; same direction if locked.

It doesn't make sense to have a differential locked when driving on hard surfaces.  Puts too much stress on the internal differential parts and tires.

Here is the dirt on the Massimo T boss 410 UTV side by side differential. It doesn't have one in either the front or rear. It’s simply a ring and pinon gear set. Therefor it can not be unlocked. It’s always, permanently locked! I asked Massimo if there is a locking differential option for this model, NO. Is there an after market locking differential available for the 410 side by side? So far google has not found one.

My MSU 500 is the same.. rear is not locked under 2wd position and front axles free wheel . you select 4wd, then slide cover and press LOCK .. it is much harder to steer in lock position .. warning sticker  next to selector .. DO NOT EXCEDE 18 MPH in LOCKED position..

About whether there is a "locking differential" on their UTV??????   There is so much misinformation appearing here from folks that don't have any idea what they are posting, check it out for yourself rather than jumping on the smart phone or computer and asking questions.

very few atv's or utv's have an unlockable rear differential, in fact the majority have no rear differential, the few that do actively promote them as having "turf mode".

atv's and utv's are not designed to be driven on hard surfaces

Sorry to disappoint you about the rear "differential" There is NO DIFFERENTIAL in the rear! The rear end is just a ring gear and pinion, If you doubt what I am saying jack up both rear wheels and with the shifter in neutral and the parking brake off, spin one wheel, if the opposite wheel turns the same direction as the one you are spinning there is no differential when you turn,  the wheels slide around the corner, both at the same speed

Hey, I'm just passing along some information I got from a Massimo tech.

      Hello All,
       
       I am trying to find a Scanner that is works for a 2016 MSU500. I found the Tiny Scan TS301 that looks like a decent Scanner but so far have not been able to get confirmation that this works on and older model. It has been stated that it works on the 2019 and newer but not sure about older models. It appears that the ECM/ECU/EFI modules are likely interchangeable between a 2016 and the newer 2019 and on but not sure of the Scanner. I am waiting for feedback from Hisun on this issue right now.
       If this unit is not usable for my model year has anyone found and a Diagnostic Scanner for the older machines, one that works and is Affordable?
      Thanks for reading my post and any information that you may have to share,
      Robert

      I have a 2020 800 sx with about 16 hours on it.  From day one I have heard a clunking noise from the front end going over bumps.  Has anyone else experienced this?  Also this past weekend while out riding I heard a noise that sounded like the dump bed bounced three or four different times, again has anyone experienced anything like that.  Thanks, gary

      I have a T-Boss 750 and I have had to put 2 starters in and put heavier wire to the starter but it still has a problem starting. it will turn over and than die before it wil turn over again. could it be that there is to much compression that might cause this problem

      I have a 2018 T Boss 550. It is currently in the shop for an exhaust leak. The shop is telling me that Massimo (SCAutosports) is out of the exhaust gaskets along with numerous other parts.  Is there any other resources for parts and is this a problem anyone else is having?

      I've looked long and hard and can't find an oil filter.  Wondering if there is one.  Any help would be much appreciated.  Also, live in Canada - we have no Massimo service centers or dealers, only HiSun.  Are HiSun and Massimo related?
