Writing a maintenance plan

I wouldn't overthink it. Most fleets have a 45-60 day inspection program. The shops they send equipment to will have a sheet of things to check. Get one if these and copy it. You can change your oil at your preference.

 

My 95 W900L doesn't have one either. It's easy to figure out though.

 

How do you know that the clearances are within acceptable limits?

 

I have...

All I did was start a basic spreadsheet and recorded in sequence everything I did & do on my truck.

Included that along with printed receipts in a file and the auditor was fine with it.

They just want to ensure you're taking care of your equipment.

 

So you Plastiguaged all of your Rod and Main Bearings?
What was your oil clearance?

 

No. My "maintenance plan" is the spreadsheet that I started and maintain since my authority was established in 2016.

Don't over think it

 

Have you considered a Crank Damper for that Cat? It would certainly smooth it out and if that, Harmonic Balancer that is on there currently, may be no good.
They're kinda pricey, but, money well spent, especially on those E-Cats.
