Kraton Kraton gearbox sealing problem

[Ombretuti]

Hi
I bought a kraton v3 two month ago.
I used it in a sand mine mostly. After fifteen batteries, there was a loud cracking sound from the rear differential. After disassembling, the gearbox was full of sand, and the main diff gear has two worn teeth, and the input gear seems worn too. It was factory state, I have never opened it.
Last week when I changed the oil in the front diff, there was no wear in the gears, but there was some sands in the front gearbox too. So there is no other reason to this wearing then sands.
How can I seal the gearbox so sands cant reach the inside?

Thanks

I just purchased one. Hoping to receive it Friday. Did you buy anything tires etc for beach playing ?

RPM a-arms, rear mudguards, and bumper. After many long jumps, the plastic parts still hold, but sand is bad for metal parts.

I'm going to make a gasket for between where the gearbox and the chassis. I'm still trying to figure out which material to use. I notice particles in the gearbox when I do maintenance. I'm sure water gets in there also. Maybe you could try to seal the crack between the chassis and the gearbox with some sort of plastidip.

I use a thin bead of gear grease to seal up the gear boxes

Same problem running my Talion at the beach. I too now apply gear grease with a Q-tip along all the mating edges of the gear case cover and around the outdrive cups and bearings.

I changed the bearings for a rubber sealed one. Because the sands can reach inside through the factory bearings. And after 10 battery I usually clean the diff house. But i mostly use the car in a sand mine. Its not good for the metal parts. But the plastics never broke.

I just fill them solid with a synthetic gear grease.

I have the same problem and considering getting those gaskets. Will let you know how it goes...
