2.2.1.8 The use of the Cat design mark (1E0198F) is preferred over the word mark (1E0198A) for Cat branded components, however, either variation is acceptable to apply the Cat brand to a part. Some materials and processes may not allow use of 1E0198F. If in doubt, the Caterpillar engineer should confirm whether the supplier can apply 1E0198F before releasing a print with this specification variation。
