Avid/Polaris drivers

[TRS]

If anyone can confirm 3" pitch track on 8 tooth 2.86" pitch Avid drivers will work let me know.
I know a 3" pitch will work on the stock 8t 2.86" pitch polaris drivers but the avid driver is a completely different animal and I dont wanna be the guinea pig.

I can check when I get home, but I don’t think that will work.

Same for 7t 2,86" Polaris drivers? At least as well as With the Stock 2,6" Polaris track?? If so, maybe there is a New track waiting for me..

Tony?

As a track stretch’s it will move the following driver lug further away from a track lug. With that said a driver that contacts track lugs would be crucial. Engineer designs don’t always work in the real world, as we have witnessed again of late.

Let’s ask Indy Dan about his drivers. They are fast.

Indy dans drivers are indeed fast.
(I had a set on my 2011 pro)

They fit well at rest. (No tension)

Thanks, please let me know. Ordering a new track soon but don't really wanna buy drivers again.

The polaris 3” pitch drivers look like they have an excessive amount of room for track stretch. TRS I’m curious what track and approx miles you used in the pics. Thanks for the info.

PC with a couple hundred miles on it.
I measured the distance between drive lugs on the PC and a PII 3” with 2200 miles and there wasn’t a significant difference.
The PII was installed, the PC was a take off.
The PII drivers would need track shrinkage.

Cool. And when you say they were fast, can you quantify that?

Smoother running track,
Less variation in track speed under load. (No other changes)

Call it a butt dyno experience (since I didn’t do any drag racing or speed runs)

The downside?

Smacked a rock and bent my steel splined shaft. (1/8” bow in the center)
The only bent splined shaft i’ve eVer heard of.

(Spun it on the lathe and trued up the drivers to match the bend and it’s still running true)

I tried a 2.6 pc 153" on pro 8tooth 2.86 drivers and went about 50 miles before it was ratcheting all the time. Had track super tight too. Couldnt make it stop.

Now running 7tooth axys 3.0 pc with no issues on same sled. I dont run extroverts or the center driver.

That's kinda hacky no?

Same issue

Are people saying the avid 2.86 extroverts are better for the 3.0 pitch powerclaw.

I don't think so. If you have Avids, use the correct pitch driver for the track you have. Supposedly, if you have the Poo 7T 2.86 drivers, they will work on a 3" pitch track... Personally, I always ditch the Poo drivers and install Avid drivers for the track I'm using.

 

[PISTONPETE]

OK, Dumb Q's here ?? Could one put a 2;86 track on POLARIS 3' drivers ??

 

[PISTONPETE]

Anyone ?? Wondering if I go to a 2'6 and just swap rails ??

 

[alexkravets]

Gregg called and asked if I would compare the 3.0 pitch drivers. Robbies drivers get the job done.
Polaris’s 3.0 pitch driver drives on one lug, Polaris’s 2.86” pitch does a better job on a 3.0” pitch track.

You have to Understand that this track stretches a little bit.So that fit will change

If you look at the track in the pic, you will notice there are plenty miles on it. The stretch is definitely done.
