5th Wheel Question

[Hammerhead]

I'm not familiar with the Fontain 5th, but I've done several Hollands.

Here is my guideline for deciding if a Holland 5th is worth rebuilding.
you have to clean the grease off first, crappy job
1) Is the plate flat? Yes=good, No=No go
2) Does it have any grooves worn into it? No=good Yes=No go
3) Does it still have the fine machining grooves in it, or has it worn smooth Yes=good No=questionable
4) Has it "keyholed"? Where the pin rides, is it a larger diameter there than the opening where the pin slides into the ride position? No=good Yes=scrap
5) Do I really feel like getting filthy doing a $h!tt¥ job, or do I have the extra $$ to just swap it? Yes=maybe No=F##k NO!
