98 tbird -- rear wheel bearings R&R

Anyone help me R&R these? I'm using the haynes manual that says punch out the bearing from the opposite side using a drift punch. But there is a sleeve inside the wheel that prevents me from getting the punch on the bearing... at least not a good enough contact to hammer a punch against.

I'm also looking at either the Batlax BT45 for my front wheel, or a Bridgestone S11. The Bridgestone S11 only comes in a 110/90 18 size, but the BT45 comes in the 110/80 16 size, which is the correct size for my bike (1998 Tbird non-sport).

Thanks

Stephanie
PS. My rear tire is a Bridgestone S11, hence the desire to have a matching front Bridgestone...

The stock front is a 110/80x18 on the Thunderbirds.

Early Tbirds had 160/80x16 on the rear
Later ones had 150/80x16 on the rear.

I choose alternate sizes based on the outside diameter spec that you can find on most manufacturers website.

I put a 100/90x18 on my Tbird with a 150/80x16
when I still had it.

I'd use the 100/90x18 on the front if I wanted the s11 tire.

The tire I'm looking at getting is the Bridgestone S11 110/90 18 for front. That is an aspect ratio of 90%, compared to 80% that's called for in the spec. 90% of 110mm is 11mm more than 80%. That's a hair less than a half inch in tire height.

tire height (from rim?) for:

110/90 = 99mm
110/80 = 88mm
100/90 = 90mm (only 2mm higher than spec!)

I'm thinking tire height is critical since too much would affect handling.

It will also reduce the clearance between fender and tire.
You would probably notice a difference in handling with a taller tire.

And it will make the speedometer inaccurate.

When I replaced the 110/80 with 100/90 my speedometer was much closer to the GPS.

Look up the outside diameter on the bridgestone website and you'll see the real difference in ride height.

they do make a 100/90x18 in that s11 tire.



My opinion about this is worth exactly what it cost you to read this post.
YMMV as usual, but it makes sense to me to keep the Outside diameter closer to the original.


The other thing that will effect handling is the use of a bias ply tire instead of a radial.
The originals were Radial. But, there are very few radial tires available in the Stock sizes.
Avons are the only ones I know about. And it is not a good idea to mix radials and bias ply on a motorcycle.

I've ordered the BT45 Batlax tire, 110/80 18. I forgot to ask if it was radial (although the guy who ordered it for me also sold me the rear S11 tire... so he probably would've said something if it was radial... I don't think the S11 is radial (?))

I'll let you guys know how it turns out (I was hoping for a front tire that matched the rear).

Denny, I couldn't go with the 100/90, because I already think my front wheel looks too small, compared with the rear.

Later,

Steph

These are both bias ply tyres (non radial). Radials were the standard fitment & generally are better, but these older style designs are getting made with the more recent rubber compounds according to their maker's info. (Think the 045 rear may even be dual compound?)

I suspect Denny's right about Avons being about the only radial choice these days. The 16" being the more limited size. Maybe keep an eye out for a Legend (early model, Akront alloy) 17" wheel which is a straight bolt up.

Usually you can push the distance piece (sleeve) slightly to the side, enough to get the punch on the inner diameter of the bearing.

If you warm the hub with a propane torch it makes it a lot easier to drive the bearing out, just don't get it so hot you can't touch it.

Ok then, please elaborate if you don't mind John (lol) how do I use the propane torch thing. Sounds like something only the experienced should try out.

And I don't have one, so where should I go to get one, cost, used or new, etc.

Thank you John!
