I just looked in my 03 Performance Manual where it lists part#'s of MANY 11, 13, and 15 wide upper and lower gears and there is no listing for a 43 tooth gear in any of the widths...... <_< Sorry I couldn't help.
That part # 1602-418 is a 13 wide 43t (15 Spline)
Just so ya Know Some of the 15 Splines are Different.
Cat now uses a Polaris Spline so a Polaris gear will fit and is a Better gear! Not (Powder Metal).
I would think the F7s AND F5s are the same shafts as the 03 440 SnoPro.
If so, We use Polaris Pro X Gears on our sleds!
Black Magic is ok ?,, Speedwerx has the right gears in stock now.
I orderd a 44 from B/M And got the wrong spline, Yes it was the 15 spline But they will not fit the NEW 03 Shafts.
03 440 Snopros run 13 wide.
And I have a Collection of gears, The 02 Snopro gear would not fit on the bottom of the 03s. They have different Splines~ Ones sharp 03s ~ 02s are flat. I could see it fitting if the spline had wear, But I all ready had a battle with this gear issue at the start of the race Season. Speedwerx can Confirm what I am telling you. Call them.
