Larger oil pan, frame change and skid plate

Recommended Posts

I have done a number of things to my Trooper over the past months and am now trying to get caught up on posting. As we all know, hot oil seems to drop the oil pressure considerably leaving us concerned for our engine. To help the oil stay cooler I built a larger aluminum oil pan and now hold 9 quarts and has a drain plug that reaches out where I can easily get at it. The oil pressure does stay much better. It still drops down but not as far. I also removed the frame tubing that runs front to rear under the right side of the engine. I wanted to convert it to a bolt in frame section so I can remove the oil pan without removing the engine. Now I can do a lot of work to the engine lif necessary because I can completely dismantle it while it's in the Trooper. The new frame member is part of my skid plate. The plate is a piece of 3/8" thick aluminum with another 1/2" aluminum plate welded to it directly under the diff. The plate bolts on real tight and becomes a strong structural part of the frame. Prior to this I had a piece of 1/4" thick aluminum plate under the diff. This worked fine until I went through a dip with a rock sticking out of the ground. The Troopers diff hit the rock quite hard as the suspension compressed. The hit put a hexagon shaped hole in the plate from the drain plug on the diff. It took the hit but I decided it needed more. Now I can do the same dip and the skid plate bounces over the rock without damage other then a gouge in the plate. The one pic shows the top side of the plate with the frame replacement bar as part of the skid plate. Also where I placed the strip of steel shows where a bracket goes that holds the lower side of the differential. When the plate is removed, the bottom of the engine along with the diff have nothing under them. Makes for easy servicing.

      Hey all, I bought a Hisun 550 back in June of 2019. After 6 weeks of ownership, this machine took to sputtering when started and under power. I checked everything I could think of before I took it back to place of purchase....(rural king), since it had a one year warranty.   They kept it almost two months stating they were waiting to get info from Hisun to rectify the issue (supposedly faulty drivers seat belt). I was told by the tech that they replace seat belt harness and cured the problem. It did! Ran just fine again for almost a year and now the very same issue has returned. After doing a little investigating on my own, I noticed that rural king did not replace the seat belt harness at all.  The wires to seat belt connector was cut and spliced and taped back together. Now I’m not real sure what the real problem is as that tech is no longer with company and can’t seem to locate the past work order for my machine.  Hisun customer service is non existent . I’m on my own and begging for help. Im mechanically inclined but if this is an electricical issue, I’m screwed! No warranty left. Any help would be gratefully appreciated.

      Hello Folks - newbie here with my first post so go easy on me.  I picked up a Buck 400 in May 2020 direct from Massimo when they were doing a closeout sale on the 400 models.  I read the reviews and was skeptical. 
      We live in a golf cart community  we do not plan any off roading - just some very mild work tasks like hauling firewood / brush etc.  Honestly, all we do is cruise around our neighborhood roads.  I pulled the trigger b/c the price was cheaper than a 2WD lifted golf cart and the Buck  had way more features.
      We have a few steep hills and after about 20 - 30 minutes of cruising, my check engine light comes on.  It only happens when we are going up or down one of the hills .  We head straight home and things seem fine the next day.  Light never comes on unless we tackle multiple hills during one ride.
      Should I be worried?  
      PS - Unit is 4 months old and has 258 miles on it - barely broken in.  I've yet to go full throttle on a flat or up a hill.

      HELP - my wife and i just bought a 2013 joyner trooper 1100 and we rode for 2 evenings with no problems. Went to ride last night and all of a sudden it acted like something was catching up and it didn't want to move easily. Whatever it was must've broke and now it moves with no problem but is making a rubbing/grinding noise somewhere in the backend. Could it be wheel bearing, differential, or something in cv shaft. Any info or similar experiences is appreciated.
