This snapshot is out of date as soon as the machines run. If your Cat 745 runs 52 hr a week instead of 40, its service lands around Apr 15. If it sits at 24 hr a week, around Oct 15. goAardvark reads real hours from Cat, Deere, Komatsu and Volvo telematics every day, so the dates stay right.

Official Cat maintenance resources

Your 745 isn't the only machine due for service

Most fleets run several makes side by side. Each has its own manual, intervals and telematics portal. goAardvark pulls hours from all of them and builds one PM schedule for the whole fleet.
