It is Walt. I’m ordering the parts this week and will update with some pictures when I’m doing the install. I took some during disassembly for anyone interested in doing this on their own OTK hubs. Haven’t driven my kart in over a year so I’m pretty excited to get the parts and install them.

Thanks a lot guys.  They were really easy to remove after the advice given and I will let you know how the install goes. Lots of good tips and it should be pretty straight forward after some of the pointers mentioned here.

Walt – on the second bearing (the one where you mention they need to be lined up, I noticed there is a step for the bearing to sit on. For this reason I don’t think I have to align them up as they each have their own step that should line them up. This is something I didn’t notice before and may be particular to the Tony hubs. Regardless I will ensure the sleeve is centered before I drop the 2nd bearing in.

Thanks again.

Thanks Dave

Will the spacer ring come out after the hub is heated or is it a non removable item?

Just out of curiosity it seems like it would make sense on the installation process to remove the spacer ring (part G in diagram) and press the outer bearing in 1st. After this I would drop the cylinder in, followed by the inner bearing and press it in with something until it sits flush with the cylinder.

Does it help to freeze the bearings for installation and if I do freeze them will I need to heat the hub again?

I’m aware that extremely hot things that are cooled down too quickly can sometimes crack (glass for example). Is this true of bearing material or no?

Might be a simple thing for others, but as this is my first time doing it I want to be aware of what can be damaged so I can avoid having to spend money unnecessarily.

Thanks!

hahaha of course John.

Thanks a lot for the replies guys. I got a lot more information than I was expecting. I was just trying to understand if they were sort of stuck in their  respective forms of racing. Didn’t know they made centered oval track karts since when I lived in NC and dirt tracking was the dominant form of karting I only saw offset chassis being used.

Appreciate the insight and we plan on going out in his modified GX390 sometime soon to compare to my TaG 2007 EVX with a 1st gen PRD Motor. Should be fun to compare the two and see how they feel on a track like Grange which has both left and right hand corners.
