Solution for Valcrum Oil Cap for Trailer Axle that is Leaking Oil

Updated 11/03/2025 | Published 01/15/2025

Question:

I have the Valcrum oil caps on my 10k axle dual wheel tandem am I believe it’s leaking around the gray fill plug or around the red piece or even around the cap it’s self.how could I go about fixing that. And is it normal to have to add oil every now and then I have to add some oil about 5 times a year it only gets used to haul hay so it sits a lot

Hey Weston, we have repair kits for the Valcrum oil caps like you have with the part # VA85JR. This comes with Lens, Gaskets, Lens Retainer, Vent Plug, and Screws so it would fix the leak. You really shouldn't be leaking that much oil so yeah the repair kit is definitely in order. We also have replacement caps too if that's something you'd rather go with?

Hey Weston, how did things go after you used the repair kit for your Valcrum oil caps? Did it stop the leaking around the fill plug or cap area? Your update could make it easier for others with the same issue.
