I will be able to offer them in either a 7 tooth or an 8 tooth driver in 2.52 pitch.

I've started a thread on the two stroke site on my progress.

I've got a few sets made up now. Going to retail a pair of new 8 tooth drivers with adapter bushings installed for $95.

Price is right, but I have a couple questions. First, How are you ensuring that the square drive is centered within the hex driver? Second, What materials are you using? It looks like some type of plastic material (e.g., HDPE, UHMW, UHMWPE, nylon, delrin, etc.) with some sort of metal square drive insert (or maybe that's just a discoloration from where the driver has been pressed onto the shaft?). Either way, the plastic material appears to be pretty thin near the corners of the square drive, so I'm also wondering if in testing these, you have logged some real world miles (as opposed to installing a track and running it on a stand) to see how the drivers hold up?

I don't make the drivers. They are an off the shelf driver I get from kimpex.

The bushing is a hex od to match the driver ID. It centers itself when you press it into the driver. The square is centered in the hex bushing.

Material of the bushing is 6061 Aluminum.

Bushing is 1.5" long and fully in cased inside the driver. Despite wall being thin in the corner, once its all assembled everything is under compression. There are metal band clamps on OD of driver too.

No trail time yet as I only began working on this over the summer. If I had any doubts I wouldn't be offering them for sale yet. Remember....this is an 18 hp motor....not 200hp sidewinder. Ha.

For those that don't want to do a skid swap to accommodate a 121" track I'm working on a rail extension kit. Extensions get welded to stock rails. Welded my test set up friday. Hoping to install this week to test fit then add set of wheels and weld nuts on for tension adj bolts.

Anyone know how tight to set the track on a LT bravo? I put a used track on my sled and I can't seem to find any info on it. Thanks

like a banjo lol

 

[maim]

usually just tight enough for it not to skip when it has good traction on the older air cools I still run.

Out of my 2011 manual.

40-50mm with 10 kg pull. Converted to American ... 1.57-1.97 inches with 22 pounds downforce.

My interpretation is that I want to be able to get a 2 by 2 in without too much trouble when the track is hanging slack under its own weight only. Seems to work, I have 5k miles on the original sliders and they are still 80 percent easy.

Thanks a lot, that's a big help.

Attached are some photos of my 121 rail extensions for the bravo. They are steel, so just get welded to the stock rails. Added a set of wheels, and a cross shaft in the rear. The assembled skid has my prototype extensions. Last pic shows the production extension profile. Nuts get welded on for track adjuster bolts. Will work up pricing for the rail extension kit soon.
