IMPORTANT:
RIGHT HAND (RH) balancer shaft for John Deere 4-239/4-276 engines. JD engines use a PAIR — RH (AR69710) and LH (AR69711). They are NOT interchangeable. If replacing both, order each separately. Weighted style with bolt-on counterweights.

Do NOT confuse with RE26282 (also RH) for the earlier 4039/4219/4239 series — different shaft. AR69710 fits 4-239T engines with s/n 746396 and earlier on 2555/2755/2855N. Failure symptoms: pronounced vibration, rumble from crankcase, accelerated bearing wear. Follow service manual for balancer-to-crankshaft timing.

⚠️ Confirm RH side and engine serial number before ordering.
