Has anyone had anything to do with such parts as ... plastic drive cage rollers ( wear 3 to 4 times better than steel ) ? aluminium rollers ( front, rear and centre bogie wheels ) ?? non CAT tracks ??? What other aftermarket upgrades are available ?? 6400 hours on our 277B, 3400 hours on the 277c, both in " hospital " at the moment !!
Camoplast offers premium tracks, claiming 30-40% more life... I'm skeptical on the plastic drive cage rollers outlasting steel... I could see aluminum idlers/bogies being an upgrade.
