350 rancher crank bearing

Does anyone know where the Support crankshaft bearing is at? Iv been told if the engine is in as it is normaly there is a kinda round cover on the front side of the motor and iv been told that is where it is. But i would rather have confirmation by people who know more about them then i do.

What year and model 350 Rancher are you working with? What do you need to know (and why) about the crankshaft main bearings? Need more info to get on the right page with ya...
Thanks,

See page 12-22 of the FSM if you are working on what my best guess is... that you're working on. :-)

The rancher is an 2004 Footshift and another question. How do i get the front driveshaft peice off so i can change my one way clutch bearing. Turns out when ever i bought this 4 wheeler for $1500 like new no scratches at all or mud stains but me nor my dad knew that it had been sunk before but it was smoking just a tad when you would get on it. So this is the 2nd rebuild so im putting all new bearings that i can get to easily without splitting my cases and some of the seals that are important new so i hopefully wont have anymore problems out of it in the future or at least till i sell it. Thanks in advance for all the answers.

Ohh and the reason i need to repalce it is when it did run but had to redo the timing chain and tenstion and guids. You could hear in the front like a bearing that sounded like it was ticking/clinging in the front its either my one wat clucth bearing which is like already done for or that support bearing. Sorry for so many posts i keep reading you comment RETO and keep adding my input

ok, for one, lets start from scratch. if t's been sunk ?, you REALLY need to pull the motor, split it, and flush/clean the motor out !. why ?..simple..you already rebuilt it once, and that failed !, want it to fail again ?, then do as I say, pull the motor, split the cases, flush/clean the inside out very good !. or your going to be right back to where you are right now in maybe 10 miles ?, maybe 1 mile ?. there is grit inside that motor that is eating your bearings up !!. as for the front drive shaft ?, if you will get the service manual, which you really should have done to begin with !, you would see it tells you to unbolt the front differential ( if this is 4x4 ?, cuz ya DID NOT SAY ?? ) pull it far forward as you can, then pull the drive shaft copular off either the front pinion gear ?, or the front output drive shaft spline ?, then you can get the front cover off, but in this case, you should really be working on just pulling the motor, and doing what ive been saying ^^^, the motor has been sunk, don't waste anymore time or cash !!, do it right, or don't do it at all. your time, your cash, my know-how !, your call :-).

and if you do decide to do it right, and pull the motor ?, this would be a good time to replace all oil seals, as well as a new cam chain, seeing how you will have the motor out, and apart :-). I've been down this road sooooooooooo many times with motors, it takes time, a little cash ?, BUT IT'S WORTH IT IN THE LONG RUN !.

that drive shaft copular is just stuck on the output shaft bro :-). just pull it off. it may take some '' help '' with a drift punch, or screw driver on the flange ?, but all that is holding it on...is nothing !. its just pushed on the output shaft, and has a o-ring under the motor side lip, nothing to it :-).

just for chit and giggles , is this the same trx350 rancher you worked on awhile back for a top end job ?, I remember this trx350 !. and it was sunk so you say !?!, and i'm pretty sure I warned you, as well as a few others, BACK THEN !, to split the motor, and flush/clean it out, or am I wrong here ?. and now your right back where we told you, you would be..correct ?..lol. I won't say anything else, as I think I've covered it enough :-).
