LedFTed a dremel tool, may just grind what is left of the bearing. you dont have to grind the whole part. just on one side. then it should fold in on it self. with a bit of help, and pry out. the bearing should be on any parts fiche. the outside part, of what is left of the bearing, is in a housing, and i would try to leave 98 percent of it there, if not more.
i doubt the bread trick would work on this one..
Today 03:59 PM
simplegreen Ok, well torn out the shift motor and the casing. Soon as i did the bearing on the larger (circle gear) feel to the garage floor. So the good news i know my problem.

Bad news is i think the outer casing of the bearing is still there. Any suggestions on getting it out? (picture below)

Second question. I assume while i have it tore out its best to just replace all the bearings and such. Can anyone point me to a rebuild kit for a 2014 420 Rancher ES?

retro If any of you guys reading this thread are looking for AT preps info you're not gonna find it here. ES systems only. :-)

retro Ya, the Rubicon has an automatic trans though. It was a DCT in 2016 I'm pretty sure... none of the info in this ES thread is meant to be applied to those systems.

There are a couple posts beginning here outlining the preps and materials you'll need.

While the front fender is off clean and dielectric grease every harness connector pair in the bike. If you need any help start a thread with all of the relevant info. And let us know how it works when you're done.
got 2 extra sensors.

Yeah the 2014+ has the shift motor the goes into another chamber where the gears are. I didn't confirm it but it looks like those gears are covered in engine oil. Looking at the schematics attached. you can see the motor mounts to a plate, that plate mounts to front of the engine where the gears are housed.

Again, i just want to make sure im not going to introduce something that would be detrimental to a piston.
i looked at the setup on the 2000es while not exactly the same. it is so similar. i got the same bearings and the same gear set up, on the 2000es. maybe not the same gears. if it was bathed in oil, i doubt you would need grease.
make any sense?

ATC4ever Wow "Much Music Digging through the Vaults" I had to go back to page 2 to find that
What i ended up finding was that the 'new' Rubicon's shift motor shaft is in a little bit of oil, whether submerged or splattered on it, but the gears had this sticky goo I had to scrape off before applying the white Lithium grease. It made very little difference in the 2016 i had, (did it twice at that...) So with the help of a buddy of mine who is a tech at a Honda dealer, i got the ECU flashed to a 2017 i think it was. It did shift faster then, but still not like the old 2003? TRX350 4x4 i had here one time. That shifted like there was no tomorrow.

MarkChamorro I made an account because I just wanted to say thanks to all you guys who help out.

I just bought an '00 Rancher ES knowing it had a shifting issue. Assuming it was a shift motor or angle sensor, I caved and bought it for a decent price. Now I find myself opening the front crankcase tomorrow to see if there's anything broken. But like I said, you guys are a plethora of information, and I appreciate it all! This is my first ATV so I'm completely new to this, although fairly mechanically inclined, so I'm sure I can figure this out by reading all of the threads and responses on this forum. Thanks again guys!

One of the main problems with Honda ES systems is that an improper grease type (and an insufficient amount) was put in them at the factory. So when you service yours clean out the original grease (clean out the support bearings too) and repack & reassemble using any NLGI #2 synthetic bearing grease. Mobil 1 is cheap and readily available in a 1 pound tub...
I'll give it a go thanks a lot
