bearings

[honda400ex2003]

Hey guys, I am doing the bearings on my buddies foreman 450es that is a 2000 model. I am wondering if when we do the two for the axle in the back we need to do the one that goes to the motor via the cv axle. It is the one that surrounds the final gear from the motor. Also do you know if they are a different size when using the aftermarket ones. he got a kit with 3 in it they are all shorter and wider than the ones that are in there. The new ones do not fit in the space. I said they are wrong so he is going to call denniskirk. thanks guys steve

You will most likely have to pull the whole rear diff. out.
It will make life easier!

I agree on pulling the rear out, Much easier. Also the bearings should be snug going in that you will have to press them in or tap them in.

We had to take the diff off and take it apart. we have the old bearings out but the new ones don't fit in it. Does anyone know if they are a different size when using the pivot works ones? the numbers and everything match from the pivot works site and dennis kirk but they are much shorter and wider. Also with the one around the final drive from the motor I am wondering if you have to change that one. Thanks for the help guys. steve

I'm not sure I understand what your saying. can you take a pic and post the two bearings side X Side?
Also while you are in there might as well replace the on at the final.

Sorry I dont have them my buddy does. The ones that came out are for an example 16mm wide and the ones that we got are like 20mm wide and the the ones that came out are 33mm and the new ones are about 30mm. So the old ones are are like a jetta tire on the car being narrow and taller for the snow, and the new ones are like a rear 400ex tire. short and wide. I hope that helps that is the best I can do till later today. Also I am wondering how to get the final drive gear out that connects to the cv shaft. I think inside of the front half of the diff is where the third bearing is. It looks like it is held in with some sort of clip but I do not see one. this is the link for the schematic

I am looking at the 2 bearings marked 33 and the one marked 26 but I can not get the number 4 part from the motor out. not the spindle gear. I need to get the number 5 out but can't find the part that is open on the end to spread it.
thanks for all the help guys, steve

EDIT I'm am not sure without being there. If you have an old needle nose you can grind them to make the type of clip puller you need.

[honda400ex2003]

I dont think it was at the end with the bolt we got the bolt off but it does not pull out of the diff. That is where i am stuck. I can not get it out. Do I have to change that bearing anyway number 26? Otherwise I will leave it alone and just put in the other two. Steve

If you can see it and it looks good I would say let her go for now.

[honda400ex2003]

i dont see anything that I can even use a puller on cause that was my first thought. I don't know. I will have to try to clean out all of the grease and then look inside it again. There is a hole in the case of the diff that has a silver ring you can see down inside. I think that is the number 5 but I think it needs to be spread apart to get it to pull out but I don't see anything.

[honda400ex2003]

I cant see the bearing itself just the outside seal from the outside of the diff. Thanks for the help steve

[honda400ex2003]

i think they all went out because there was no oil in the diff. We pulled it apart and there was like 5 drops that came out. that is the olny reason I am worried about this one. steve

[Eviltanker]

5 drops..... That will lead to the mess. Tell your buddy to keep up with maintenance to avoid these situations. Sorry I can't help you more.

[honda400ex2003]

alright thanks for the help, hopefully someone else knows about the front of the shaft. The gears still had oil stuck to them so at least they were not grinding. steve

[honda400ex2003]

We just found out that there are two kits for the rear. one for the diff and the real wheel bearing kit. We need to get the wheel bering kit and the other kit. Where do the ones in the real wheel kit go? At the end of the black housings and by the brake on the right side? thanks for any help, steve

[Eviltanker]

maybe this?

[honda400ex2003]

that is the one without the diff in it. I never even looked at that one. Thanks, I have those bearings for the ends. Now I am geting the whole story here. It never occurred to me that there was more in there on teh ends until today when my buddy showed me the other bearing set for the diff only. Thanks again for the schematic. Steve

[Eviltanker]

Anytime bud

[honda400ex2003]

We got that set changed tonight. There were two that went in the brake assembly and one that went on the opposite side of the axle in the black tube. He is ordering the diff bearing kit and will have it tuesday to put in. I didn't think that there were that many bearings inside there. thanks for the help with the schematic steve. Maybe I will do a how to when I am done with it. steve
