Wheel bearings are shot!

Okay so no big deal I would have thought...

So I got my bearings/seals ordered, and headed home to take out the old ones, wow...I'm getting nowhere. tried a hammer and screwdriver but they just arn't budging, I guess I'll either have to pay to let them take them out, orrrrrrr maybe order the special tool. What do you guys think? Has anybody had any luck with replacing wheel bearings themself?

Bummer gyro just when you get all your new goodies together something crapps out.Sometimes it worth it to invest in the right tool but I can't see you having to do this very often. It shouldn't be that much if you take it to them all in peaces. Wonder why your bearings are bad already. Lots of water crossings or what? :)

I looked at one of the seals, and when placing the wheel spacer in I noticed one side was alittle looser then the other :) so ohwell, the season is over anyways... I didn't expect to get any riding in except for the occasional run though snow when the snow hits.

I'll just let the guys at the shop do it, and I better get a rim lock while I'm at it.(shoulda done that when I got my new tire put on but I forgot since I was in a rush)

ohwell whatever, money is for spending.........on our toys :D

Also I think what killed the bearins, is since one of the seals was bad, some sand must have gotten in there and ruined the bearings. Atleast my front wheel is good

So guys, if you have your wheels off, check your bearings/seals. It costs less to get new seals compared to new bearings.

Check your local rental center, a lot of them rent nice bearing remove/install kits, check out renting tools at checker. Also you my need to warm the hub with a little torch action, remember to heat the hub not the bearing.

Hotler is right. try warming the hub.also,make sure there isn't a bearing retainer,or circlip thats preventing the bearing from coming out.i just put money down on an `02 S model--picking it up next month so i'm not familiar with the details of these machines yet. either way, that bearing should come right out of there with some abuse.who cares if it's the proper way or not-grab a screwdriver and hammer and something to support the wheel with enough clearance for the bearing to come out. it will come out.

I'm sure that you can do this yourself. I did this just this summer. Wheel bearings have interference built into the hubs--so the bearing is larger than the hole in the hub. You heat the hub with a torch for about three minutes to expand it then from the backside hammer it out with a long punch. Then to install the new bearings heat it again and pound them in with a bearing driver (I got mine at a auto parts store for about $10)

heh, just got back from taking removing the bearings. I finaaaaaly got them out, just took alittle pounding and abuse :D But thanks for the advice anyways, because I will have to install the new ones.

When I get the new ones I'll just ask the guys at the shop for a bearing punch to install them. They should have one or atleast be able to order one.

hehe.....when the bearing started to move a 1/8th of an inch a big smile appeared on my face, then a couple more knocks and it fell into the garbage can the rim rested on :D The bearings from the other side came out alot easier with the centre tube thingy out of it.

The hub contains 3 bearings.

1 side has 2 bearings (1 large 1 small)

1 side has 1 bearing. (1 small)

I don't know why it is the way it is, but for anybody who ever needs to remove bearings, remove the side with the 1 bearing first. This one will come out easier. (if thats not already obvious to ya)

Anyways, saved myself 30 bucks(canadian) in labour charges. Which is all that much better since I'll need that when I order my cyra front disk gaurd :)

awesome buddy!! i knew you could do it!!

a little trick for installing the new bearings: heat the hub and put the bearings in the freezer.the hub will expand and the bearings will contract-sometimes allowing installation by hand! if it's not that easy,just get a socket thats just a hair smaller than the outside diameter of the bearing,make sure the bearing is going in straight,and tap her home! just make sure the socket doesn't touch the rubber seal inside the bearing or you'll be reordering bearings!

Way to go gyro!! :):D

smittyman, how can you only have 8 posts to this forum!? You seem pretty knowledgeable about bikes. It's good to see helpfull members around here. Thanx for the tips about cooling/heating the parts, thats exactly what I'll try when I get my bearings.

i just discovered this site a couple weeks ago.glad i can help!i work on motorcycles for a living and i drive a `72 elcamino for summer and a `71 c-20 p/u for winter so i'm no stranger to a wrench,i guess!

cool, well congratz on the purchase of your new 02 s model!


You may wish to add a little extra wheel bearing grease to the new bearings before installing them. If they are double sealed you can pry the plastic seals out with a ice pick or dentist pick. They snap back in place real easy.

Then look at the dust seals and decide for yourself which way you want to install them. Several DRZ400E I have worked on have the rubber dust seals installed with the lip and tension spring to the outside. Most other bikes have that part facing inwards. I reinstall mine inwards. With the spring outside it is easy to dislodge and lose the spring when wiping dirt and grease from the outside of the seal. I pack my dust seals with Polylube 2000. Its a light synthetic grease you can buy at bicycle shops for under $10 in a 1 lb tub. Any waterproof grease will work including white lith. Also works under the dust seals on the forks.

Rockymountainmc.com now sells bearings and seals real cheap. I bought a whole set just for spares but probably will never use them. If you have spare bearings from other bikes you may look and find they are the same part #. Two inners are 6004. Same as the rear on 90-94 Cr500 and 92-94 cr250 Hondas. One outer is 6204 which is found on the left side of most big Xr and Cr Hondas. Seals are MK029NI AND MHSA2842 6J.

yup yup, got some of that grease, just have to get my bearings/seals first.

As for the seals, I think I'll go with your suggestion and install them backwards. Can't hurt to do this anyways.

Gyro: I think it is Suzuki that has got them backwards on the rear wheel. Another benefit to installing the dust seals with the spring inside is you are using a different wear surface on the wheel spacers. Also the outside is now flat and easily wiped clean.

Be sure to check out the front bearings and keep them lubed and moisture free as they are way pricier than the rears.

yup I am going to clean up the front when I do the back

      I'd like to turn my UK 2004 DRZ400S back to stock airbox (snorkel) and jets, needle shim position etc
      When I bought it the PO had fitted a Sigma6 kit and done the 3x3 mod but is doesn't have a tapered needle like the JD and other kits. Took me ages to get it running right, however it still runs rich and I'm fed up of arsing around with it. 
      So I've bought a standard airbox without 3x3 hole, stock exhaust.
      Q1 The Suzuki manual says this Mukuni BSR36 (29FA) carb should have a 142.5 Main Jet but the Clymer manual say its a 135.  In UK everything's from sea level to 1000m. I'm in Sheffield so nothing gets above 500m even in the Peaks (Hills). Any UK owners or anyone else know what the correct jet should be?
      Q2 Says the original needle is a '5DH36-2nd'. The needle has 5 notches on it. Currently set at 2 clip from bottom. The Suzuki reference says needle is 5DH36-2nd, Does the 2nd bit mean 2nd from top or bottom?
      Q3 - Does anyone have a detailed photo of the shim order just in case it was assembled wrong. (mine is attached)
      I know most people on here are going to be horrified I'm taking back to stock but any help on above would be really appreciated.

      I've read a lot of threads about this but still haven't found exactly what I'm looking for.  I'm pulling my 2004 DRZ400S out of storage sometime this week and getting it ready for the season.  I live at 9,000 ft, but my first ride of the year is probably going to be at around 5,000 ft.  I was going to pull the 145 main jet I'm running and put in the 150 adjusting the needle from the 2 clip to the 3rd, then re-jet once I got home.  I already have the extended fuel mixture screw in place so I started thinking that I should just run the 150 jet set up and adjust the fuel screw to compensate for the higher elevation where I'll be doing most of my riding.  I will be going down in elevation for rides until late May or June depending on snowfall, but riding on the street when I'm able.  Are there any disadvantages with this?
      I'm new to posting on this forum, so please forgive me if I didn't get the right search words in and there is already a post about this.

      Good Morning,
        Last night I measured my valve clearances for the very first time (I know...) on my DRZ400S.  It's a 2002 and I've owned is since 2011.  I bought it with t's got about 15,000 miles on it and most of it's miles these days are on dirt.
      Intake specs are 0.10-0.20 mm.  Exhaust specs are 0.20-0.30
      My intake valve clearances are in spec, forgot to write them down.  My exhaust valve clearances are between 0.1778 and 0.2032 which is slightly out of spec.  They are no more than 25 microns out of spec.  My question is, do I really need to shim these?  Will this kind of out-of-spec cause performance, mechanical, or other losses?  As far as I can tell, I'd have to buy a whole shim kit which is like $80.  Thanks!
