1999 Polaris 500 Diesel / starting issue

Recommended Posts

Hey here's a topic you don't have everyday.  Wanting to buy a quad on Craigslist ( 1999 Polaris 500 Diesel ). Guy bought with intentions to get running well he has no time for it now. PO said it ran one day and not the next. Current owner said it looks to be ridden hard in past. Im wondering what issues it has about starting?  Most likely has a bad fuel pump or clogged fuel filter.  ( i thought all diesel engines had fuel filters ) Does anyone have any suggestions or experience with these models? Thanks

I was checking out eBay for a fuel pump and there isn't much but there's some switches that could cause it not to start ( safety switches ) like a thermal switch and a couple other switches. Easy fix i know but just no experience with diesel engines.  $1200 hundred bucks is the asking price, and it comes with a winch & plow so it's a 4- wheeler. they only made these for 3 years 99, 20 & 2001 Thanks for reading.

I wasn't aware either till i saw it on Craigslist.  Now there's another one on Craigslist. Same issue. Im just interested because I drive a semi-truck for a living, and it's weird.  It's a Polaris 500 Diesel it's got huge letters on side of tank DIESEL.

I have a polaris diesel ATV. I think it is a 1999. Runs great. Had 2 batteries but replaced them with a single utility tractor battery. No problems starting, even in sub-freezing temps. Only issue is when going from 4wd to 2wd the front end seems to stay engaged/locked, making it difficult to steer. Also had some issues with shifting to low, but some tweaks to shifting rods have resolved that. A fantastic working machine.

May be a joke to some, but truly is a beast of a machine (especially for those that want a work machine).

I'm in the middle of putting a 99 diesel into a 2009 frame....

I bought the engine (nothing with it) by mistake (thought it was a different engine till it was too late to back out) and it sat here... a week ago I found a free to me 2009 500 with a locked up engine...

  so far everything will be simple to swap out... mounts are in the same places, hoses hook up the same, and the clutch will swap as well.  Its good to read you like yours, I'll try to keep you updated on how this one turns out.

Got it to run today, just needed the injector cam/throttle linkage freed up... Got it in place, what a pita working the engine/transmission in that hole... I'll have to move the two front small suports a little forward and move the mounting brackets a little but everything should work out well... Also will have to change the drive belt to be a little longer.  Dayco has a wonderful page that list lengths/widths if anyone ever needs it.... Maybe even do a new thread once its complete... But its not like your going to find a lot of Polaris diesel threads on here...

Fyi - mine had 2 batteries. Switched them out to 1 bigger utility tractor/mower battery. Never had an issue starting, plus a lot cheaper than the stock mc batteries.

      I have a 2000 Polaris Sportsman 500. A year or so ago we got it running after replacing the kill switch. It ran great but after some use for a couple months it got a flat tire and for some reason we just forgot about it and it sat for some time. Before it sat i replaced the gas cap, fuel filter, fuel pump, petcock, battery, starter relay, oil and oil filter. I recently went to start it and it started so quickly and without choke or throttle but the ATV wouldn't move till about 1/4 throttle and it wasn't really a smooth ride until 1/2 throttle. it also would bog out randomly after you came to a stop and sounded like it was getting too much fuel. I cleaned the carb and adjusted the air/fuel screw to 1 3/4 turns out.  I also messed with the idle and the throttle cable adjuster up on the handlebars. It's safe to say it now runs worse than when i started working on it 2 days ago. It takes more effort to get started and bogs out idling after about 30 seconds. I tried adjusting the idle but every time i do it'll get to a sweet spot but after driving it down the driveway and back the idle will go up and down to the point where i can't put it in gear because the gears will grind. Any thoughts or ideas would be greatly appreciated. Thanks

      Got a 04 Sportsman 500 that wasnt running- owner said it needed a stater and a new battery.  It ran rough (been sitting out in the weather for a while).  A friend and I started by adding a new battery and it would start barely with the choke and his hand over the air-filter.  I decided to install the new battery in the holder on the side.  we had it on the rack because the old on was still in the bike.  I tried to be nifty by turning the battery to put the terminals in an easier spot to get to, but forgot to reverse the cables too.  In a sentence, I reversed the positive and negative on the battery like a dummy.  When we discovered my mistake and corrected it, we turned on the bike, but the display did not light up and the key did not turn on the starter.  jumping the solenoid worked the starter, so we thought the solenoid just burned up when I reversed the pos and neg...  new solenoid and no difference.  what have I burned up?  Also, the shifter does not seem to do anything in the trans.  it slides back and forth like its stripped in the trans.  any help would be appreciated!!
      I think the biggest issue right now is the electrical.

      I'm working on a 2018 Sportsman 570 and found in the service manual that there are two different torque methods for the head bolts depending on whether the bolts are silver or black. Well, silver bolts came out of my engine and I'm going to be replacing them with new bolts, however the parts fiche doesn't specify bolt color or that there is even an option!?! 
      Has anyone on here been through this before and can offer insight??
       
      TIA

      I've never done this before but after reading a few thread I decided to check my valves for the first time and to my surprise it was much easier than I thought.
      My bike is a 2005 Sp 500 HO.
      I first pulled the seat and the right side panel off, and that's it! It wasn't too bad to get at.
      Next I pulled the spark plug out and removed both the head cover ( 8-8mm bolts)
      [ATTACH]1021[/ATTACH]
      then the side cam cover (5-8mm bolts).
      [ATTACH]1023[/ATTACH]
      Also remove the plug in the recoil cover (14mm bolt) to see the timming marks.
      [ATTACH]1022[/ATTACH]
      Next I turned the engine over with the pull cord untill it was at TDC of the compression stroke.
      The best was to tell that your at TDC of the compression stroke is to rotate the engine until the
      timing marks are parallel to rocker cover gasket surface.
      The cam sprocket locating pin will be facing upward directly in line with the crankshaft to camshaft center line.
      Now fine adjust by looking into the timing hole in the recoil cover and line up the upside down "T" on
      the flywheel into the center of the hole.
      [ATTACH]1023[/ATTACH]
      Now using a feeler gauge, slide the .006" (.15mm)blade between the top of the valve and the bottom of the adjuster and adjust accordingly
      [ATTACH]1024[/ATTACH]
      [ATTACH]1025[/ATTACH]
      To adjust, Loosen the locknut (10mm) and check clearance with a feeler guage. Clearance should be .006" (.15mm) for both, intake and exhaust valves. Turn the adjuster with a stubby flat blade screwdriver untill the proper clearance is achieved then tighten the locknut (5.8-7.2 ft. lbs) while holding the adjuster in place with the screwdriver. Re-check the clearance with the feeler guage one last time and re-assemble the covers (72 in.lbs) and plugs.
      The only thing that i noticed was that I had to clean and silicone the side cam cover other than that I found the whole process rather simple.
      I'd give it a 4 out of 10 on the skill level scale.
      I hope this helps!
      Thanks Rich
