Service Magazine SEPD1385, 20 January 2012, "The Track Shoes for D7G and D7H Track-Type Tractors Have Been Updated to Classic Track Shoe Part Numbers". Disregard this article. See the replacement article that follows.

The D7G and D7H Hybrid track shoes have changed. This change applies only to Hybrid tracks that have 3/4 inch diameter track bolts.

Most hybrid shoes have been replaced by Classic Undercarriage shoes of the same width. Some Hybrid shoes have been canceled and replaced by a Classic shoe of slightly different width.

The former Hybrid Extreme Service (ES) shoes can be mixed with the Classic ES shoes in the same track. However, the former Hybrid Moderate Service (MS) shoes and the Classic MS shoes are not compatible in the same track. They will interfere with each other.

New Classic Undercarriage shoe part numbers are adaptable to the machines listed above.
