John Deere B Pistons, Rings, and Rods

Rebuilding the engine on our John Deere B. Prepping piston rods for assembly and overview of piston ring orientation

[@natedillard7353]

Good thing you caught that! I think that inner chamfer causes the ring to expand under compression to make the best seal possible … My A has two channeled compression rings instead of one like the B’s I think …. Nice work !!

I've also heard that upside-down rings will lead to oil consumption

[@rustyoldmicrofarm4673]

Good catch on the rings, thanks for the info!

[@jonelsonster]

Yes, I'm really glad I double checked!

[@JonathonBoucher47A]

Where were you able to find your pistons/rings?

[@jonelsonster]

I think we bought these from Miller tractor out of PA. But we've also bought from Kuhn's out of South Central New York.

Always pays to double check.

Trust, but always verify.
