Product Notice

As a parts distributor we mostly sell aftermarket parts (any OEM parts would be noted as such). Aftermarket parts are not sourced from the original vehicle or equipment manufacturer, but are designed to function the same as - if not better than - the original. All parts sold are new.

• John Deere 4045/4045T/4045H PowerTech 4045 (4.5L, 4-cyl) (1992-2015)

IMPORTANT:
LEFT-HAND (LH) balancer shaft gear for JD PowerTech 4045 (4.5L, 4-cyl) and 6068 (6.8L, 6-cyl). 15 teeth. NOT interchangeable with TR120637 (RH). These gears are a DIRECTIONAL PAIR — LH and RH must be installed in correct positions. Installing in the wrong position causes severe vibration and potential engine damage.

The balancer assembly reduces inline engine vibration. Replace as a set with TR120637 (RH) if both show wear. Inspect balancer shaft bearings and housing bore. Confirmed OEM via Shop.Deere.com as R120639.

⚠️ LEFT-HAND gear. Right-hand is TR120637. Must be installed as a matched pair.
