Rancher 420 Rear end rebuild

Recommended Posts

My 07 Rancher rear end started roaring on me the other day. I took the inspection plug out this afternoon and to my dismay it was dry full of rusty nasty crap. The pinion was loose and the axle seal was pissing out oil when I tried to top it up. I bought it used and usually check stuff over better but I missed that.  Muuuhhh :( Now I gotta take it apart and fix it. Not gonna be expensive, just time consuming. Hopefully the gears aren't too torn up. I cleaned out the nasty crap with some brake-clean and put in some fresh gear oil. Much quieter now just leaks out all the gear oil cause the seals are shot. I'll fill it up with some lucas and limp it along till I feel like fixing it.

Its good you know how to tear it down. Hopefully no internal damage. Those quads are normally great quads. The rear end is often overlooked.

Yeah their not to terribly complicated. Nothin but some nuts bolts and a few cotter keys.  I'm pretty sure the gears are O.K. Just a little corroded. I'll post some pictures when I get it torn apart.

I have a Honda rancher and those atvs are built like a tank.  They're worth spending time to keep them running.

I've ridden Hondas for years. I won't own anything else as far as ATVs go. My brother has a 98 artic cat(Suzuki). Its got nice suspension but nowhere near the power.

      Hi,  I'm looking for a repair manual for a 2011 Honda Rancher 420 ES.  I've been looking on here and have only seen manuals for the 420 AT.  Does anyone have a PDF that would be willing to share?  
      Thanks in advance.

      I am trying to put a 1994 Suzuki 250 quadrunner back into service. I have it up and running like new but need to replace the plastics as they are brittle and crumbling due to age and sun exposure. I would like to purchase new parts either OEM or aftermarket but have had little luck in finding them. I would even consider used or salvaged parts in serviceable condition. Any help in locating these parts would be greatly appreciated. Thanks in advance.

      Ok, so I bought this scream of a deal the other day - a 94 King Quad 300 for $40.00.  It's been sitting outside with no carburetor on it for about a year.  Its rusty, missing some parts, wiring is all cut up and spliced etc.  No seat, no racks but the plastic is all there minus the headlight housing.  Anyway, who can pass up a $40.00 quad right?  I get it home and looked at the sight glass for oil level, it's about 1/2 oil and 1/2 water.  I drain it, refill it and turn the motor by hand (recoil starter is missing) and it turns over just fine.  I worked on the wiring for about an hour and got it to turn over with the electric starter and got enough of it sorted out to get a spark.  Did a quick compression test, 70 lbs.  Wet test bumped it up to 90.  Ok, so rings and cylinder washed out with water for a year, not too surprised.  I thought 'what the hell' and sprayed some starting fluid in it and it ran for about 2 seconds - enough to show  it's got life.  Since then the compression has gotten worse, I can't get enough pressure to activate the carb diaphragm, therefore no fuel pump either.  The compression is now around 60.
        Anyway, my question is....is it worth it to try to get this thing going?  I tore the top end down today and the cam and one of the rockers is pretty worn.  I figured a top end job would be about $100 or so, depending on the condition of the cylinder but I'll probably have to put a cam and rockers in it as well.  Doing some research on ebay I figure I'll have to spend about $500-$700 to make the whole machine right again.  Much less just to make it run and use as-is but I won't really like it until it's right.  I don't mind doing the work, I actually enjoy it but I'm concerned about what all that water did to the rest of the internals, I can't really test it all out until I can make it run.
      I know it's a basket case but I'm not into it much at all, even if I do the top end and find something else wrong I'm still not out much.  I'm leaning toward ordering the top end parts and going from there unless you can convince me otherwise - any way to check the rest of the internals without tearing it down?  I plan on flushing the oil cooler before I do another oil change, I've drained it twice now and it gets milky almost immediately just turning the starter - I suspect the oil cooler is polluted badly.
       
      I'll get some pictures today if anyone want to see them.
       
      thanks!

      If you're getting that pesky leaky seal on the pinion of your front differential and the pinion has allot of play, polaris won't sell the bushing needed to repair it properly without having to shell out big bucks for the complete ring and pinion kit. 
      I have a kit with an upgraded bushing, Japanese made bearing and USmade seal
      50 shipped in the US and 55 to Canada

      I replaced the fuel pump filter and it ran great for a week or so. Then while driving across the yard in 3rd gear it shut off and hasn't started since. It has fire and its getting fuel, all fuses are good, battery fully charged. The fuel pump relay seems to be warmer than it should be when spinning it over. Any help is appreciated!
