2001 250 Recon - Ring Gear Spacers

[Coyote251]

Hello,

Hoping someone can help me out. Just picked up a 2001 Recon for my son, got a good deal on it but the rear-end of the bike came in a box (pieces). I have gone through and inventoried what I have and what I need but I am not sure what size ring gear spacers I should get. I have a new pinion gear installed and a new ring gear to put in it, all of the other bearings and seals are replaced also. So since this should be pretty much like a new differential, I am thinking that "F" is the right size (1.56) based on the manual where it says this is the "standard" size. I am thinking that I need to start somewhere before I worry about measuring backlash.

Any input or advice would be appreciated.

Yup. Just as you say. Assemble it with whatever shims you have and then check and calculate what difference you need(if any), and then go from there.

These days things are made so  accurately that it's quite possible that the original shims which were chosen for that case will be right again.
