Rocks stuck in accelerator

David Justice

Recommended Posts

Hi all. I just recently started taking my Trooper T4 back out into the desert here in Phoenix, AZ. I've been running on a mix of sand and rocky terrain and I've noticed an issue and I am wondering if anyone else has encountered a similar situation. The other day, I noticed that my gas pedal would stick at max throttle. It did this twice before I realized that I had a rock(s) stuck somewhere above the gas pedal. By simply repeatedly actuating the pedal it's full travel (with the motor off) small pieces of rocks would dislodge from above the pedal and the pedal would spring back to normal. I assumed that I had solved the issue but it proceeded to do the exact same thing 2 more times. The last time it happened, I dislodged a large rock. The issue hasn't repeated itself since but it did leave me wondering how that large of a rock got into that particular area. The first time this happened, I was actually stopped and the engine banged off the rev limiter a few times until I killed the ignition. The next 3 times I was hauling ass and only discovered the problem after I let off the gas and started braking. The second part of my question is, if anyone has experienced this, have they put something in the chassis to block rocks and debris from catching in this area? I have an early 2009 T4. Thanks.

I have caulked all of the seams and open cracks between panels in the entire floor area. Also cut some foam to fit in the upper forward corners of the center console which was glued in. I have installed a panel that covers the entire dash area from the back side to keep dirt from getting under the dash area, most anything will work.. I also have a piece of foam plugging the vertical hole that opens from under the front, behind the diff, to the area under the center console. For this area, I used a piece of 1-1/2" thick polyethylene foam. It is stiff enough that after squeezing it into the area, it stays there without any anchoring and seals around the edges good. I have a larger then stock radiator so if closing up the channel that goes under the console if effecting the air flow to the engine area, I'm not having a problem from it. Side venting the engine area helps with that. Closing these areas up good, as Ricksrb and Kinarfi said, keeps a lot of dirt and dust out of the cab area.

I did some of what Lenny has but I also used a spray in foam sealer for the cracks and open spaces under the dask and in the floor. My T2 has a full cab enclosure with jeep style zip up windows. Finding and sealing al the open spaces keeps all of the dust out of the cab, now I just need to install a heater due to the -5 degree weather I have been hunting in.

      Hi all, New member and new joyner trooper owner here.
      Just picked it up yesterday. I worked for it. -40C here in Winnipeg, Canada loading it into a trailer. Unit was too tall. Some ratchet straps, recopricating saw and a lot of F^#ks. 
      Anyway she came with a broken front driveshaft. One of the ears was cracked off. I have a replacement but i am unsure how the driveshaft comes off the transfer case. 
      Doesn't sem to pull off or have any way to remove it. Any suggestions??

      I thought the problem was electrical but I just found this in the oil filler tube. Does anyone recognize the part? I know I'll have to tear down the whole engine, and maybe I'll find the rest of it in there. Something beg enough to seize up the engine. That was the problem I was trying to diagnose.... 'Cause it's locked up. 
      Thanks in advance.

      I have owned my 2015 Hisun HS700 Crew  for about 3 or 4 months now. I got it used and was supposed to run good but was not put all the back together from a stator upgrade due to previous owner said he was going to out a stereo system on it. Anyway I have worked it much more than I have rode it. I seem to work on it 2 days and ride it for a hour. Me, my wife, and 2 kids (10 and 18) enjoy it but the engine compartment gets so hot. I've replaced the water pump and burped the cooling system and any other thing I could think of to bleed the air out and think its good with no air and water circulating. Fan seems to run fine and be on about all the time. Changed the coolant twice and oil 3 times. I noticed the engine really has nowhere for heat to go because heat rises and no air flow at all. Has anyone had any experience in this area? Any DIY tricks or any advice in removing the heat out of the engine compartment and getting it to a tolerable temperature. Im about to sell it if I can't figure something out and go waste money on a big name brand but I won't have red legs and arm from engine heat burning me and my wife. They machine never acts like its to hot or anything but it feels like it is. Thanks in advance for any and all help.

      Hello everyone.
      Here I am showing our Green Scout electric all-terrain vehicle.
      All-terrain vehicle 6 wheeled, electric, side-turning. Rides, jumps, dances, swims, but does not fly. The drive is permanent (but you can turn off any wheel arbitrarily through the controller). The power of each wheel is 3 kW at its peak, the total power is 18 kW. Speed up to 60 km / h. Since the all-terrain vehicle is electric, it starts from a place quickly, drives silently (well, of course, the sound from tires and shock absorbers does not disappear).
      The idea of creating such an all-terrain vehicle came after the experience of operating the Argo all-terrain vehicle. The main disadvantages of the wheeled side-turning all-terrain vehicle are low ground clearance, lack of suspension. To get high ground clearance and suspension, there are two outputs on mini all-terrain vehicles - either electric drive or hydraulic. The hydraulics had to be excluded, since at temperatures below -30C it does not work, plus it always flows. As a result, we settled on an electric transmission. Each wheel is a motor-wheel. Naturally, the motor-wheels were being finalized to be able to be installed on an all-terrain vehicle and to be able to swim. The battery is iron-phosphate, all information on the battery, the charge is displayed on the smartphone. Control of the all-terrain vehicle through the on-board computer. Bicycle handlebar controls. Braking either with the sides through a turn of the steering wheel, or with the gas pedal of all wheels at once.
