Well that brings back memories of me fitting a banana box on my 406😆. Ironical I fitted a 421 box to my 406 snowblower, you’ve done the reverse! I would say, keep a spare set of seals for your box or be ready to keep filling with oil 🙂. Nice to see a rockinger being fitted👍 if you ever get chance to buy a muller-mitteltel trailer, get it! They’re a lovely trailer.

The banana box of the 411, 421 and 406 are the same. There's only an early version which is a little bit smaller on the bottom part and a newer version which is wider to hold more oil. They changed it due to heat problems

Always nice to have the "Banane" on a Unimog and a second one with perfectly good spares. In some weird twisted way the chain driven relocating gearbox wasn't too far off. The really old 401s and some 411s also had a really simple chain drive one. Open, with no guard, fixed to the holes in the frame end left and right with a bar going to both sides just below the tow hitch. It had the secondary purpose of stiffening the tow hitch for higher tung weights. Early 421 already had the relocation box shaped like yours but smaller and still chain driven on the inside. So whoever built it was on the right track but not there yet. The chain also shouldn't really have to be that tight to function per design. But the chain was probably too weak to transmit the power spikes. If I remember correctly the chain gearboxes on the Mogs had double row chains. The wear on your sprocket probably didn't help. One thing I noticed: your rear cross member seems to be thinkered with? Looked to me like there was weld on the bottom corner, which should just be bend? The additional plate around the hitch and the hole for the PTO seems also a bit weird? It looks like someone tried to beef it up, which surprises me as it's already rated to pull 13+t at full speed (which it will never reach). The banana gearbox is important if you need your pro center for like a muck spreader. But if you just want it lower, to do your cardans a favour, there is a little hack. You can just mount the bearing block of the PTO below the cross member on the same holes. You only have to take an additional look at how far your axle can travel and maybe limit that. But I see quite some people doing that. I also saw somebody mount the PTO bearing block below the axle on the rod where the lower links mount to. Not just that it costs ground clearance, but it must be hell for your joints.

The chain drive wasn't a bad set up in some ways, but I wanted to fit a tow hitch so I needed to make room for that with the centraliser gearbox 🙂. Yes the rear crossmember has been modified and plated - not sure why as there is no obvious damage to the original! This did mean the holes that should have already been there for the mount were plated over though - so that's the reason for having to align things with the bottle jack etc and drill new holes. It was one of those jobs that was meant to be an afternoon, but turned into days of work spread over several months! 😁

@@Classicworkingvehicles Unimog always turn into a lot of work. You either do work with them or on them. I wanted to exchange der Rear cross member on mine. Thought of it as a Weeks worth of work. Ended up in a complete tear down and already 2 years of ongoing restauration.

I really like your unimog,I own a unimog 1600 agri in Ireland brilliant machine's to work on Keep the video's coming 👍👍👍

Thanks! Yes, gotta love a Mog! 😁

Great vid, good work. Was a wee bit nervous around 14min mark with your overall sleeve and the running PTO stub shaft....

I‘m wondering about the engine. Is this the om616? Doesn‘ t sound like that. And you‘re driving really fast 😂
