Expert Maintenance Review
To keep your product feeding system in top condition, accurate gearbox output shaft alignment is critical. Standard preventative maintenance for the 7120 series requires precise alignment performed in accordance with CNH recommendations to ensure optimum service life of the splined components.
Damage to splined bushes and shafts is directly associated with incorrect alignment during installation.
Recommended Maintenance Upgrade
For a total feeder house restoration, we specifically recommend inspecting your Feeder Floor and Lower Idler Drum bearings when installing this drive kit.
