........??? We change fresh air cab filters every 250 hours and recirc filters every 500 hours. It isn't that dusty here and they always come out well dirty.I have had several out over the years. Most are always full of mud. Seems like the cab filters always get neglected. It is a pain in the butt job. But once done will be good for many years.
You do realize that there are two filters in that system I hope..... one outside and one inside the cab.Yup, when I did the cab cleanout on this one, that filter appeared to be a forgotten soul.
There's actually a door on the back of the cab, secured with one bolt and a hinge which is pretty easy to get to. You may find however that the filter isn't too dirty as the seals aren't worth a carrot.

There is only one louvered panel on the back of the cab that is roughly 4" wide and 12" tall. I first guessed the top bolt was all it had and the bottom "probably" just had a tab. Nope, there is a bolt I cannot even see and barely touch with my hand on the bottom. Only way to access it is remove the controller. I mean, I could probably get creative BUT what was CAT thinking here?
Now if you had an O&M manual the procedure would be right there for you ............Nige, if you have a page link on that attachment, that would be super! That things does not look fun and if I have an evaporator issue, it looks like pulling the lines, then the entire unit is the only play.
