The way I do it, or think about it,
1) buying filters from dealers, firstly check the dates on the filters, shelf life around 2 years! They will gladly sell you all the filters, but the dates will be later than the ones you take off.
2) most services are based around hours around the running hours, the engine oil and filter are important at recommended intervals, air filters can need changing earlier depending on dust conditions, hydraulic oil, in dumpers it only tips and steers so you can stretch it out a bit, excavators rely on hydraulic oil more so, and if using breakers or augers change it more regularly.
3) track motor reduction hubs, change very regularly, more so if doing lots of road work or travelling.
4) pilot filter always a consideration if the hydraulic oil is changed sooner than necessary.
5) grease fast moving parts daily more than once, slow moving parts at least once.
6) change coolant after checking its freeze temp, and it’s above -20, I know we rarely see temps down to this, but depending where the machine is stored there could be a wind chill factor.
