Reference: IRM (Information Release Memo), UC86-46, "Undercarriage Conversion For Competitive Hydraulic Excavators," December 22, 1986, 1987 Parts Sales Kit, Page 143, and Conversion Guide - Undercarriage, Form PEGP2806, Revision 1 (data summary for appropriate models).
Four sizes of bolt-on roller groups are now available for installation on a variety of competitive hydraulic excavators. The 7T6395 (215 size), 7T6394 (225 size), 4C1901 (225 size), and 7T6396 (235 size) Roller Groups will bolt directly onto a significant number of competitive excavators without modification to the end collars or mounting surface bolt hole pattern. This makes conversion to Caterpillar roller groups easier and less costly for the customer.
