I am building a new buggy and am incorporating Mog 404/9's. My question is, is whether or not someone has loosened these hubs up at all, or the shaft snout of the big gear that the hub rides on.

Where is the press fit coming from? I mic'd the outer and inner spline engagement, and the only conclusion that I could draw is that the width of the splines are where the press fit may be coming from.

Has anyone removed material from the Unimog 404 hubs to allow an easier slip-fit?

:beer: Cheers!

(this is what I am working with for visual purposes)

weps used a sandblaster on the inside of his

Great info mog-10... can you attest that it works? Maybe weps will chime in. Should the focus of the blasting be on the lateral edges of the splines? Just blast the hub or the gear too?

I didn't do it, but Andy did tell me that as well.... makes sense but I just pressed them babies right back on :D

They were never designed to come off "easy", but I'm sure that some clearancing either of the interior or exterior splines would help. Even just a really good polishing and deburring would probably help.

My front 404s came off a lot easier than the rears. The only reason I can guess is that they were serviced more frequently, so there was less rust to bind them up. I'd say some anti-sieze when re-assembling would make life easier next time around.

I'll subscribe to this just in case you come up with a brilliant idea that I can steal. :D

I mic'd everything, and the only thing that I can deduce, is that they need some sandblastin' :) I tried the lathe already. In fact I had a guy with 150 ton press make a taco out of one of the hubs - they were on there so tight! Kinda ridiculous if you ask me - and those were off of a rear portal box.

So... I'll write back once the blastin' happens.

I have done both, blasting and running a 'flapper wheel' thru the bore.
I have taken alot of these apart and have seen anywhere from 5 to 45 tons of force to move them. seemingly with no rhyme or reason.
