Onan Generator Oil Filter Crossthreaded

Hi!
According to my service technicians my generator is leaking oil (and can’t even run) because the area you screw the filter into has been cross threaded/stripped. They say the entire bottom plate has to be replaced to the tune of $2400. I have the Compass Platinum Protection plan and I anticipated paying the deductible. But they’re telling me this is considered physical damage and therefore not covered.
Has anyone run into this? I know coverage companies do everything they can not to pay out, but this seems unreasonable. Our RV has 15,000 miles on it. Generator has 600 hours of use. Oil has been changed ever 100 hours with Onan Filters.
Thanks for any advice on how to approach Compass and get this covered.

    Can you share with us how this happened? Are you saying Superman forced the new filter at the last change all the way up to the sealing surface?
    If there is a heavy truck shop near you I would consult with them for ideas. I don't know how access on your rig is configured but they could possibly chase the threads.
    Maybe you can find a junk genny cheap for parts, use that bottom plate, and solve it that way.

    What is the exact model of your nan genset?
    Hard to believe the plate is mad of softer material then a filter!

    Who changed the filter the last time? If it is cross threaded they are the responsible party and they should pay not your insurance.

    Even if it is cross threaded, it seems it could be rethreaded by a competent mechanic or the "bolt" part cut out and installed. But, as someone said, get a second opinion. I also don't really understand how someone cross thread an oil filter. It seems to me someone would have almost had to try hard to do that.

    Definitely get a second opinion. I have had experience in fixing multiple things on friends cars that the professional technician apparently didn't want to deal with or know how to repair so they just wanted the larger dollar replace.

    What normal person has the strength to cross thread a spin on filter that is only tighten by hand??? Sounds like the last place where you had it service had some kid do the work and a wrench was used to install the filter.

    I remember mine has a piece that screws into the plate and the other side is where filter screws on.
    Need exact model of Onan from the OP to look up his genset for parts list.

    I think your service department screwed up royally and are trying to make you pay for it. If the previous servicer had cross threaded the filter boss, your filter would have probably leaked. Have you always had your generator serviced at this shop?

    I've never seen physical damage covered by a warranty.

    The shop that last changed your oil/oil filter should pay for the repair though since they are the guilty party that damaged the threads.
