NESD | I have had a couple 470’s row tracks. If you have 18 in tracks you have a narrow undercarriage. I believe you can go up to 24 on the narrow style. The wide undercarriage is 24 and above. There was also an undercarriage upgrade in about 2019 I think. The new style is supposed to disperse heat better and be more robust. You may be being told to update and switch to the wide undercarriage. You probably don’t have too, but probably is a good idea. | |
