  1. 2012 TRX420FE Rancher: What is error code 44?

    Repair & Maintenance
    Troubleshooting the above model. Electric start won't work (pull start will) and the electric shift won't work. It is showing two error codes: 15 and 44. 15 is the shift solenoid and 44 is the EOT sensor. I cannot find either of those sensors on the bike. It appears they are on the...
  2. 2012 Foreman 500 FM Won't shift

    Repair & Maintenance
    You can see that there is a larger gap on the right than on the left. The top gear is mashed onto the bushing and the two gears will not spin independently.
  3. 2012 Foreman 500 FM Won't shift

    Repair & Maintenance
    So I did have to crack the case and I found the problem. The reverse and 1st gears on the countershaft were jammed onto their bushing and would not turn independently. My guess is it was shifted very quickly from either 1st to reverse or reverse to 1st (probably reverse to 1st as that would...
  4. Convert 2012 420 Electric Shift to Manual Shift

    Repair & Maintenance
    Thank you Shadetree. I am actually trying to fix a friend's electric shift and was wondering if this was an option. It sure seems like the manual shifts have less headaches. So far I have learned that the shift motor is good but no juice is flowing to it. I'm in the process of tracking down...
  5. Convert 2012 420 Electric Shift to Manual Shift

    Repair & Maintenance
    How easy is this? My thought is just replace rear crankcase cover, add new seals and O-rings, buy shift spindle and mounting hardware, move the stuff from the old cover and reinstall. It can't be that easy, however, and I am sure I'm missing a lot. It looks like there are some sensors on the...
  6. 2012 Foreman 500 FM Won't shift

    Repair & Maintenance
    Manual shift Foreman. The shift lever clicks like it is shifting into a gear but nothing happens. It won't go out of neutral into either first or reverse. There is also no stop. You can keep shifting forever in either direction. Again, it feels the same way it does when you shift a working...
  7. 08 Rancher TRX420FM fuel pump won't work

    Repair & Maintenance
    I can finish this post off. A little late, but maybe it will help someone. One of my wiring harnesses had a connector with a bad "stay put" tab--that bar on the connector end that prevents the connector from backing out of the harness housing. When I plugged the harness in, this one wire...
  8. 08 Rancher TRX420FM fuel pump won't work

    Repair & Maintenance
    These are my thoughts. There are only two possible causes: mechanical failure or electronic failure. Mechanical would be a loose wire or poor connection or some other issue that prevents current from getting to the pump. Electronic would be a failure of a component that produces or routes the...
  9. 08 Rancher TRX420FM fuel pump won't work

    Repair & Maintenance
    I will add that the bad machine ran when I parked it. As mentioned, I have two. This one did not start as well when it got colder, so I covered it and ran the other all winter. I was helping a friend with an 07 Rancher sometime in November, and he needed an injector. Rather than wait two...
  10. 08 Rancher TRX420FM fuel pump won't work

    Repair & Maintenance
    The machine is still in Alaska. I am in the lower 48 for the summer. All this transpired as I was getting ready to leave, so I didn't have a chance to really look into it. I'm obviously not getting 12V, however, because if I was, the good fuel pump would have kicked on. It did not run at...
  11. 08 Rancher TRX420FM fuel pump won't work

    Repair & Maintenance
    I have two 08 Rancher TRX420FMs. I had to pull the injector out of one and it sat all winter with no injector. I finally decided to get it running when it got warm. I pulled both machines into a garage and put in the new injector. It turned over fine but would not start. Problem was that...
  12. 2008 Rancher TRX420FM stalls in reverse

    Repair & Maintenance
    I’ve discovered that it is cheaper to buy a new cylinder than have the old one re-bored and buy the oversized rings and piston. (At least it is when you live where I do.) There is very little scoring of the cylinder wall, so I’m hopeful it’s okay. I just need my machine good enough to drive...
  13. 2008 Rancher TRX420FM stalls in reverse

    Repair & Maintenance
    Hello Kentco, I just pulled the cylinder on this. I discovered that one ear is broken off the piston, and the other has two significant cracks. Needless to say, I have a new piston on the way. Everything else looks fine (i.e. crankshaft is still tight and isn’t missing a thrust bearing...
  14. Cold weather start sequence for EFI Rancher

    Repair & Maintenance
    I use that procedure with my second machine, and it has given me no trouble unless it is very cold. I also have noted that -20 seems about the break point where starting is bothersome. We had a week of -25 last winter and I couldn't get it fired up. But I've never failed to get it running at...
  15. Cold weather start sequence for EFI Rancher

    Repair & Maintenance
    Gotcha. I'm familiar with the term ECM, but ECU threw me. My ECM/U is brand new. I've been pondering this, and one thing has come up. There is a black sensor that sits on the left side of the throttle body. It has a probe that extends into the intake chamber and is actuated by the movement...
