new tires, wheels fought me a bit

Perseverance pays off!!!

If you are likely to be using the TTR in the wet (muddy lanes or salty wet roads) then it is really worth investing in air valve seals such as Steve sells here https://totallyttrs.com/epages/699105d9-e4cc-4b32-b236-84e72cd67f84.sf/en_GB/?ObjectPath=/Shops/699105d9-e4cc-4b32-b236-84e72cd67f84/Products/TTR-0624

Also, if you have a flat washer under your tyre clamp retaining nut consider fitting either the shaped washers or the complete nut and shaped washer kit - here https://totallyttrs.com/epages/699105d9-e4cc-4b32-b236-84e72cd67f84.sf/en_GB/?ObjectPath=/Shops/699105d9-e4cc-4b32-b236-84e72cd67f84/Products/TTR-0312 and here https://totallyttrs.com/epages/699105d9-e4cc-4b32-b236-84e72cd67f84.sf/en_GB/?ObjectPath=/Shops/699105d9-e4cc-4b32-b236-84e72cd67f84/Products/TTR-0311

They help keep the water out of the tyre so that you avoid corrosion on the inside of the rim and generally make changing tyres/tubes a tad more pleasant biggrin

A tip I would give to anyone buying a new (to them) TTR is to check the front and rear axles will come out and, if they don't do so easily, give them a good clean, make sure they slide in and out OK and then grease 'em up so they don't seize up in the future.

You don't want to find yourself stuck out in the boonies with a puncture and not be able to get a wheel out

Well, round 2 goes to the bike. when trying to get the axle out, the outer bearing on the sprocket side seized onto the spacer, and that is seized to the axle. I will post a picture tomorrow. Anyway, took it to the local bike shop, and they got the bearing off the axle. However, since this bearing has sustained possible abuse, I 've decided to replace all 3 bearings since I'm into the meat of this thing as it is. I will remove the other bearings and seals while I wait for the new bearings and seals to arrive, since they had to be ordered. I had 3 days to ride coming up, with nice weather. I guess that I will have to just wait it out. I've seen the article on the bearing install on the disc side. Any other hints for this job?

Thank you.

Hi Jim.

Is this the web page you have looked at http://www.ttr250.com/Wheel_bearing_replacement/TTR_wheel_bearing.htm ?

yes, that's it. I've been watching youtube videos all night too.

Actually, it appears that it may be the collar that is stuck onto the axle. I am at work right now, but will show you a picture tomorrow of what my problem is.

Ah yes, probable the long LH spacer.

If it is ridged where the seal sits then you probably need to replace it which means that you could cut a split down in with a Dremel or hacksaw to release it.

Otherwise heat and careful use of an Irish screwdriver cry

Ha! I'm mostly Irish, but I haven't heard that term here in USA. Sorry, but is that a hammer, vice grips, or what? :)

I know what Irish coffee is....

Yes, the left side collar right below the chain puller is stuck on the axle. I guess I get to go buy a small propane torch and try to persuade it gently to move off the axle.

How do I remove the spacer from this side? I'm guessing I need a blind bearing puller (slide hammer bearing puller), remove the bearing from the other side, then drift this out from the sprocket side of the hub.

I got the spacer off the axle, after 45" of heat and hammer. Whew. Taking a break for tonight. I bought a slide hammer blind bearing puller. So far, no success, but the hub may need heat to get those out too. I played with it for a bit, got the inside tube to move, but couldn't get a hit on the opposite side bearing to knock them out.

I have used a screw driver with one side ground in to a curve so it catches the edge of the bearing and slowly knock it out from the other side .

Best results have been using a Dyna bolt and a punch to knock the bearing out , ive posted a picture ext on a previous thread but don't have the photo to upload a this point .

All bearings are out, surfaces lightly sanded and cleaned, ready for my bearings to arrive at the shop.

WOW, what a difference!!! She rides so smooth now, I can't wait to get back out on the trails.

3 bearings, 2 seals. I was unaware that I could get bearings from a bearing distributor until after I had already paid and ordered from bike shop. Live and learn.

Bearing and seal details here for any owner wanting to buy from a bearing supplier rather than OEM parts.
