TLR 22 5.0 using non front slim wheels

[DavidB1126]

Ok so carpet "slim" wheels/tires work perfectly fine but I have a couple of old 2wd front wheels, guessing they are normal size. They are 12mm hex but they are wider / more deeper of a hex than regular slim wheels. Once I put them on they don't like to spin freely or in some cases there isn't enough stub axle to put the nut on. Would a longer stub axle and wider hex on the car work? I can fetch pictures and/or video for you guys if needed later.

OEM part number for the axle/hex is TLR232070
They say it is adjustable. Should I put more shims so it can try to widen it a bit more so the wheel isn't rubbing on the hub?

Or do I have to use TLR narrow front wheels? These wheels I have are Jconcepts

It says 'non-slim' on my pants!

Perhaps grab a set of 22SCT 3.0 axles TLR232061 (on the right) to give more clearance for wheels with deeper hex area?

 

[CertifiedMike]

Just thicker hexes won't fix this?

 

[DavidB1126]

Well the hex is on the axle it's like a 1 piece thing so.

Yea they look thicker and longer axles too? I'll try those out. Got them in the cart.

 

[CertifiedMike]

Is this set up better than replacing hexes?
I'm trying to understand why it was designed this way.

TLR are not the only ones to do this..

Why do they do this instead of using hexes is what I mean? I just seems like hexes are a simple solution to this problem and they've been around forever.
Does this design offer better performance or is it stronger?

I'm 95% sure the SCT axles will fit the buggy's steering blocks/spindles. You would have to download the 22SCT 3.0 manual and compare inserts, bearings, and such.

That's a very good question. Less rotating mass? Better balance? I pretty much stopped hangin' out in the 2wd buggy forum threads when the B5 platforms came out. I didn't hang around to hear anyone's thoughts on what was so great about this, that, and the other stuff. Off the top of my head, I know Associated and Kyosho also use one piece axle-hex adapters on their newer gen. 2wd platforms.

Maybe just a fun new way to sell us more stuff.
Ok. Thanks!!!

Comparing 22 5.0 manual to SCT 3.0 manual

SCT 3.0
Hubs: TLR234074
Axles: TLR232061
Bearings: TLR6932
Inserts: TLR234074 (come with the hubs. Inserts look different compared to 5.0 buggy)

22 5.0:
Hubs: TLR234106
Axles: TLR232070
Bearings: TLR6932
Inserts: TLR232070 (come with the hubs)

22 5.0 axles comes with additional shims that I don't have.
Once I get to wrenching at some time Ill see if I can find some shims in the screw jar that can fit this and see if it can work, if not, maybe buy OEM axles and use those shims that come with it?

 

[DavidB1126]

Ok what I did. Took it all apart. Has 1 of these spacers so I moved it to the outside. Seems to work now! Would it be ok for long term probably not but just a temporarily fix.

How did this work out for you? I just ran into a similar problem. Bought a set of used tires and wheels that a guy was running on an Associated and the hexes on the front wheels are so deep that the wheel rubs the hub and can't turn. I was considering switching to the SCT front axles as mentioned above that way in the future if I buy up some used wheels, that I won't have to worry about it. Another concern was the impact it has on the wheelbase side to side and how that may impact handling since it was engineered to be ran as stock. I have my car handling what seems to be pretty good and I don't want to mess that up. Of course the safest route would be to just pitch those wheels and make sure that I buy ones that are compatible.

 

[DavidB1126]

Yea. Been a while since I updated this but I've been continuing to run on stock 5.0 axles and use that spacer on the outside. On the right side, it works just fine. On the left side, well shortly after my last update here on my first club race on clay with this car, that screw holding the axle into the hub, that backed out (rookie mistake, lack of use of loctite, lol) and I lost that spacer and currently looks like this. Which is ehh. No physical play in the hub with it being worn but side to side play, yes bc there is no spacer there. Lol. But plan on getting a new set of axles and hubs anyways.

Yes I also know the wheel nuts are super worn. Replacing those as well. my wheel wrench constantly slips on them. Lol.
I haven't been racing and out to the track in a long while so, huge list of stuff to all of my cars I need to do to get them all in tip top shape. Hopefully.

It still drives fine, so that's why I haven't gotten to replacing all of that!

22X hub conversion? Would be a good move if possible. I believe many have done it.

 

[DavidB1126]

22: Dialed for the most part. Actually ran it back to back for like 3 practice sessions, as today we did do timed practice sessions of 5 mins each to rotate people better as theres alot of action here today. Although for my last session was cut short, the left front hub/axle, the hub insert came out of the actual hub, probably bc the wheel hex was rubbing on the insert, wearing down the insert, so I'm gonna see if I can fix it, if not, new hubs/insert time and will most definitely find a spacer that I can use with these axles to push out the hex

Well it happened. Lol.
