520 - Have to slam doors

Recommended Posts

Hey guys, both our 520's doors seem to have trouble latching fully unless you really slam the door. This leads to a lot of "hmm, the door is rattling a lot, better open it and slam it again" at the start of every drive. 
 

The door rubbers are in fair shape (could stand to be replaced but not terrible). I can see that the door jambs have some kind of a star wheel and the doors have a toothed receiver. I don't see any damage to either

 

I don't want to make things worse by trying to take the door latch apart, so before I do - has anyone had this issue and know how to solve it? Do the star wheel mechanisms need lubricated or adjusted?

 

Thanks for any suggestions!

Clean and lube the latch mechanisms on the door and the door jamb.  Check the door hinges for wear, sagging doors.  Check the doors for adjustment.

 

Also post pictures to see if the latches hyave been changed out.

When you open the door does it drop slightly? It may be misaligned but probably hinge wear.

 

I think this is for the 510 hinge but likely the 521 is somewhat similar as far as the bushings and pins.

I just found the pics that go with this thread.  I'm not going to put them in with text at this point, but it should help the thread at least a bit 🙂

Excellent thanks guys - wasn't sure if this was just a quick known issue but this info is a big help, I'll take a close look at the door soon

Unfortunately, no, the 521 does not have bushings in the hinges.

Can you drill them out and put them in?  For a quick fix I drilled out a 620 hinge and just put in a long bolt.

Anything is possible. I agree that would be the solution, just saying it's not the same as the 510 in that regard - just cast leafs with steel pins, no bushings 😬

I ended up soaking the "star wheel" in PB Blaster and rotating it around quite a bit and the doors seem much better now - guess the latch was just gummed up and wasn't spinning freely "forward" when the door was closing. Thanks guys, I love an easy fix!
