Coleman UT400; Hisun HS400 model changes...

Recommended Posts

I acquired a Coleman UT400  just after Thanksgiving (2020) and find it to be quite different than most others seen on the web--the most visible difference is that the cylinder slants toward the rear placing the "hot spot" under the bed rather than under the seat (a significant improvement to my mind). THe curious prt of this is that neither Coleman nor  Hisun seem to acknowledge  this major design change. In fact the Owner's manual supplied with the vehicle appears tp haqve been written for a completely different unit--showing the ignition and light switches mounted in the dash (they are stalk mounted on the steering column on mine) and indicates that to change the spark plug requires removing the seat (the cylinder head and plug are under the bed on mine):

I wrote to Coleman and they sent me a what is supposed to be the most recent "UT400-5" manual which is still wrong about 90%+ of the vehicle. Neither the Coleman or Hisun websites are of any use as their content provides no photos and very little information about maintenance or the engine/drive train in general.

Is anyone aware of when these changes were made, or of any sites offering info re: this latest mode?  Currently I'm battling shift cable adjustment to find better and more consistent reverse gear selection.

Mine also differs in that the parking brake is a single caliper and disc mounted on the rear differential pinion shaft (this seems to be a "5 brake" configuration I have found reference to.

Overall it seems well designed and manufactured--the chassis welds are as nice as you could ask for and the castings and  machining are top notch.

Any information or suggestions as to where to look would be appreciated...

TIA

Kind of odd... usually manufacturers are better about updating stuff.

maybe someone at Hisun finally got it right with this one machine, lol

The owner's manual provided on Coleman's site does not even accurately reflect the machine shown in their video on the same site. In the video the vehicle clearly has a steering column mounted ignition switch--while their manual depicts a dash-mounted switch. Also the gauge cluster shown in thw video isw like that in the machine I have--the cluster described in the online manual is entirely unlike that in my vehicle--the manual provided online by Coleman  is wrong about most everything

gauges/controls from video heading Coleman's site:

gauges from on-line owner's manual:

Then there's the whole bit in the manual about using the choke to start a cold engine:

It's an EFI engine, no choke--I feel sorry for those owners that spend time looking for a choke...

Another anomaly;  In looking at parts lists for the Coleman and its cousins (the Massimo MSU400 and Bennche BH400) I ran across this reference to the engine oil cooler:

 

Note the "(2012 and older)" annotation re: the oil cooler-- My 2020 Coleman UT400 has the engine oil cooler...

      I'm in need of a brake master cylinder for my ride.  Appears to be leaking between the reservoir and the cylinder (picture).  Is there a seal that I can replace inexpensively without buy a whole master cylinder assembly?  Can't tell if the master cylinder is the same as used on the Trooper because I don't have a Trooper parts manual.  I don't know if the master cylinder is different when they went to the 1100cc engine.  Has anyone had experience with master cylinder make for the Kinrod Joyner line of rides (I believe it's a German company)?  They are available on Amazon but the configuration isn't the same as OEM.

      Howdy all,
      I searched the forum (and the internet in general) for this and didn't find anything that looked like an answer.
      I purchased a Coleman 550 from Tractor Supply last October.  Runs well.  Really only one issue that I have had and that is a dragging brake pad.  Still haven't fixed it, but hope to soon.
      For now, it is time for the first oil change (38 hours).  After some reading, I decided to use Mobil 1 4T 10w-40.  I also purchased a filter from motorcyledoctor.com.  Got the filter and noticed that there is a hex head on the end.  I thought "Hey that's nifty, but I wonder why they did that?".  Then I went to change the oil and I know why now.  Which brings me to my question.
      How in the hell is one supposed to get that oil filter off?  First off, it is not obvious how to take the seat base out to get leverage.  I thought about cutting out the plastic above where the filter is.  But decided against it for now.  I tried my best to work within the tiny space given to get the filter out.  I have a number of different filter wrenches.  Only one is able to fit over the filter.  But ... I could not get the filter to break loose.
      So, I ordered a strap wrench from Amazon.  
      https://www.amazon.com/gp/product/B01MZH57V5/ref=ppx_yo_dt_b_asin_title_o02_s00?ie=UTF8&psc=1
      In case that doesn't work, I also ordered this:
      https://www.amazon.com/gp/product/B07FVNH2QV/ref=ppx_yo_dt_b_asin_image_o01_s00?ie=UTF8&psc=1
      My intention with the latter is that if the strap wrench does not work, I will punch a hole or two into the side of the second product.  Put it over the end of the filter, put two screws into it and hope I can break it loose.
      Anyone else experience this incredibly difficult task?  I have always worked on my own vehicles and have had some difficult circumstances, but I always prevailed.  Not this time.  The Coleman 550 b*tch slapped me this weekend and is pointing and laughing at me.
      Any suggestions or recommendations would be great.  If nothing else, just some content on the subject so that someone else who might be having the same issue can find this and get some ideas.
      Thanks,
