Default Titan Center Diff Outside Bevel Gear Trouble!

I am having problems burning up the center diff and pinion gear on my Titan. The grease that was on it when the truck came worked fine until it washed off when giving it a bath. I have tried Mobile 1 grease, valvoline wheel bearing grease, Lucas "Red and Tacky" grease, etc. but they all sling off and finally the gears wore out. Could someone please tell me what grease to use on them before I eat up another set? Thanks in advance[sm=teeth_smile.gif]

Are you talking about the ring gear and pinion?

Yes, the main drive pinion and the bevel ring gear on the outside of the center diff!

Are you sure there was grease on it ? Usually there is no common lube applied there (grease, oil) because it attracts dirt and the final effect is not lubrication but grinding.

There was grease on it initially. I do agree though that when dirt, etc. sticks to the grease it can have an abrasive effect!

Indeed, from Smartech my Thunderbolt had grease. I was glad when I spun it all off. If you are running on dirt and sand with grease on the gears, that's why they are not lasting. Especially with the helical gears, it turns them into grindstones. Run them dry they'll last longer.

Try adding a shim to the pinion and the far side of the diff. this help out with the mesh. I had the same problem when I started testing on these cars. I used the shims and worked fine for bashing and playing around in the parking lot, but when I started setting it up for racing I found a few thing that would definitly improve the cars handling and rigidity.

This is video of my Titan/Hurricane at the Milestone race track. It performs very well against other large scale cars.

a glob of shoe goo or gasket sealer in front of the plastic gear cover. to keep rocks from getting wedged between the chassis and spur gear. you can also use antenna tube in the shock pistons. only 1,2,or 3 of the holes though. that will allow us to use the more common silicone weights that we already have on this side of the world.
recently someone used the foam ear plugs instead of o-rings to in the diff outdrives.

I put the Elcon springs in my Titan and it keeps the shafts nice and centered.


As for the shocks, I'm running 80 wt in the front and 100 in the rear. Works fine for me.
