87 lt 250 quadrunner universals keep going out

Recommended Posts

87 lt 250 rear universals keep going out on the right side . I mean brand new ones in 100 feet or so and the yokes just snap. Never saw anything like it the bearings have been replaced and

don't see any binding anywhere. Dad has had this quad for at least 7 years no problems with it before. Original tire sizes are on it when he got it . They are the same as the 87 quad we have I assume they are the same as the 89. He used it for plowing snow I don't think it happened while plowing only just him on the quad driving slow after a new one was put in and bang just snaps the ear off the yoke!! He as put on 6 Yokes so FAR determined to figure this out. We jacked it up and turned it and didn't see anything different than the 87. Any suggestions would be helpful.

Thanks

First you should use OEM axles. After market bearings dont hold up. Ebay usually has them from a part out.

Do have the yokes synchronized correctly per the attached?

      The rear brakes on this are hydraulic and manual. The hydraulic part is all messed up so I disconnected it all and want to go just manual on the rear. I got it all put back together but doesn't seem to work to well, like not enough pressure. The manual says I should mark the casing before taking it apart which I didn't read until to late. Any ideas? I put new brake pads on.

      Hi I have a 2007 Polaris outlaw 525 irs and am trying to replace the needle bearings in the rear a arms. I was wondering how you go about getting the rubber seal and bearing out!?

      I wanted to share an experience and a fix.
      Headed out was following a pole line, was looking for a cross track that may take me to this speckle trout looking spot on a creek.  All paths and semi paths... failed.  Second objective was to reach a speckle trout lake that has been recently stocked... followed 1 trail to dead end, followed second trail to dead end.... while investigating options on foot and the quad idling it died.
       
      It wouldn't start.  eventually it did... and when it did … it was essentially a pinned idle.  activating the throttle did seem to speed it up but it wouldn't knock out of the racing idle.  couldn't put it in gear at that idle speed.  got towed out.
      when I first got the quad, I ran it off a trail and buried it pretty good in the soft snow... eventually winched out.  It wouldn't start.  eventually did and it was fast idling.  not as fast as this last time. but still fast.  it eventually seemed to settle and I got it in gear and by the time I was back to the truck was acting ok.  chalked it up to the bike being at a bad angle in the snow.
      My investigation last year lead to the throttle position sensor TPS.  how to jumper the diag block to see the sensor position on the display,.  I focused on this nearly sure it was a detuned sensor or broken sensor again this time.
       
      I tore down the front plastic and stuck my head into the TPS area to see what I could see.  What I found was that the throttle body assembly had actually come out of the mounting area (not sure what it is called).  the ring clamp was loose I could move it easily.  Hopeful, I tore down the air intake assembly above it (air filter...etc) removed a sensor clip and a hose.
      I backed off the clamp some more and was able to reseat the throttle body assembly.  put some blue lock tite on the clamp screw.  When I was cleaning off the air intake assembly to ensure I dropped nothing down the intake, I noticed the underside of the air intake "box" also had a clamp.  this screw was completely missing.
      I went to the hardware store, bought a metric replacement (brought clamp with me), seated the assembly, settled the clamp blue lock tite that as well... 
       
      quad fired right up, idled normal, idled up without hesitation and dropped right back off.  Cost of solution $3.87 CND for a pack of 5 metric screws.  moral of my story was don't assume an idle issue is a throttle position sensor problem... there are a number of other factors including air pressure, which I believe was my issue.

      Im new to the forum and the quad I just got. I want to change oil in in. Its almost impossible to find anything on-line. I know it takes 10w40 and know the oil filter location. What oil should I use? Is there a cross reference for oil filter. The closest dealer to me is an hour away. I have NAPA close and like the WIX or Napa gold filters. Also is where can I get a Manuel for it? Thanks

      Buying a Baja 250 tomorrow for 600 bucks, needs nothing but a wheel bearing, i already know Baja is an off brand crappier. Manufacturer, but does anyone have any tips or knowledge of these bikes?

      Just bought (Tue. evening) an '89 Suzuki 250 4wd that has been sitting out the last 5 yrs. It's complete, including the shift knobs, battery cover, and headlights. It has the optional cooling fan on it (probly stuck - didn't check), and the engine isn't locked up. Plastic looks good and isnt cracked. Racks aren't bent up. Shift lever works, the foot brake moves (needs oil - have to pull it up by hand), and there's black oil and no water in the engine sight glass. Guy was asking $125 and gladly took $100 for it. Anxious to get started on bringing it back to life. Been wanting one of these for years. As soon as I can get to it (working on a junky "Jackel" right now - Chinese Yamaha Timberwolf). I'm going to pull the tank off it and clean it, clean & possibly rebuild carb, put in new plug, and a battery, then see what happens. If nothing, will keep going until it runs. Feel free to respond if you want to, I'm mainly just excited and wanted to tell somebody.

      I just bought two 1985 TRX250's from my father-in-law. One runs great, the other not so much. The one is having issues with the shifter. The shifter seems to be resting lower than normal. When I press the shifter downward, it just pops back up. Any thougjts as to what the issue might be?

      Hello all, 
      i just rebuilt the top end of a 99 Bear Tracker 250 and it can’t get it to hit off of gasoline or starter fluid. Occasionally it will backfire. Right now I’m just trying to get it to fire off without the carburetor like I’ve done a thousand times before with other engines. Usually there is no response, but occasionally I get a backfire through the intake. ISeems like it’s out of time, but I don’t see how that could be possible. 
      Here’s what I know:
      1. compression 120psi
      2. all timing marks are lined up after numerous revolutions. 
      3. Strong spark. 
      4. Valves adjusted correctly. 
      Thanks in advance.
