We completed changing the front windshield yesterday and started on yet-another hub replacement. We completed the hub this morning. The hub that was replaced was installed about 2 years ago in Helena, MT as a result of a catastrophic hub/seal/gear failure. That failure took down both gears, 4 bearings, 2 seals, the wear ring and the cast iron hub case. At the time that the failure happened, availability of parts was an issue and as a consequence used parts were installed. There were some small rust pits on the large gear race and a few small hitches on one of the big ball bearings. These parts got us from Helena, MT back to San Diego, CA. Then from SD to the north slope of Alaska and back to SD. Then from SD to Maine and to Colorado. There was some metal debris in the oil, so I was sure it was time to take action rather than let it fail on the road. I was correct. The few pits had turned into many, large pits. The race on the lower gear was starting to wear in a conical pattern as you would expect due to loading. None of the other bearings showed obvious issues, although I did not do a microscopic assessment. The race on the big roller bearing looked Ok as well. Rob Pickering and I replaced all 4 bearings, 2 seals, wear ring and the big gear. The small gear looked ok and the presence of the metal particles did not seem to do any obvious damage. Damage to the bearings sure, but the small gear is such that both bearings are replaceable. Unlike the last few hub repair actions, I did not pack the bearings with grease, but rather will rely on the Amsoil 75wt Severe Gear lube alone. As promised in an earlier post, I did assess the slop in the big roller bearing setup. As I expected there is about 2 mm of slop. When setting the depth of the big bearing, you want the edge of the rollers just a hair below the face of the big gear. The race on the gear is just a mm or so wider than the bearing, but both have chamfers and the inboard edge of the race has a trough. To Kai's point earlier, it would be easy to set the depth of the bearing too deep with bad results, but if you put them in just below flush, you are good to go with plenty of clearance to spare. This was a pretty clean installation with no real issues encountered. I have not test driven it, but I have sufficient confidence that we are just going to drive away tomorrow toward Pueblo and then C. Springs. We will, of course, check the temps, but the whole assembly rotated freely so I expect low temps. Special thanks to Rob Pickering for letting us stay in his shop and helping with the maintenance action. Happy mogging.

Both of my trucks ('55 French, and '63 Swiss) have only 6 holes in the transmission flanges, and in the driveshaft flanges. My flanges have a smooth machined mating surface, and all torque is transmitted by those 6 bolts. My spare transmission also has only 6 holes in its output flanges. I have not had any trouble with my bolts, but I do not stress them like you do. Most unimoggers would call me a soft-core offroader. I can imagine that with the crawler gears, and extreme wheeling you are into, you are just finding another weak link. Lets see: Ring and pinion Portal (or was it 2?) Coil spring Transmission Driveshaft bolts I am sure I missed some.

The notched drive shaft and PTO flanges sound like a great idea, but at least on the 404, in my limited experience, all of the drive shaft flanges and PTO flanges are smooth machined surfaces. Torque is transmitted through the bolts only. Or maybe the wedged flanges are almost microscopic? How deep would you say the notches are in the flanges you describe? Thanks in advance, and I hope to thank you in person next weekend.

If the flanges are clean and free from burrs and raised material they will fit together perfectly and eliminate the torque being transmitted through the bolts. If they are re assembled with crud between them they will not seat perfectly which can lead to the bolts coming loose over time. Now if they were running very loose you should take extra time and inspect and repair both flange surfaces with a suitable file. The bolt hole areas will most likely have raise material which will not allow them to seat correctly. If they are not seated they will surely come loose again in short order. Good Luck!

Just rotate and use the next set of holes :-) PS, I'm only half joking. My rule number one: never take apart anything on a Unimog unless absolutely necessary. Only the Elves in Germany can put it back together right.

Possibly another PTO model that was smooth. I would think that would be more standardized so as to allow for the largest selection of PTO accessories.

With the original 75gal tank and now two 55gal tanks I can carry 185gal of Diesel for a range of about 1500 miles while hauling the 406. The only reason I'm adding the tanks is that I got a hookup of 200gal of free fuel. I'll save about $350 this trip by carrying the extra fuel. Cha-ching! On that note; Scott Ingham and I are donating one of these tanks for the NWMF raffle. They go for $150-300 each on E-Bay and can be put in the bed of a pickup or whatever. This link should show photos and description: _http://tinyurl.com/3xb8x3y_ (http://tinyurl.com/3xb8x3y) If anyone wants one of these tanks and doesn't want to take the chance of winning the one in the raffle, I have a few I can bring up. I'm loading up tomorrow (Sunday) and leaving early Monday so let me know soon. I am selling them for $150 each and the proper mounting brackets and straps are about $75-100 at the local truck wrecking yard. Looking forward to seeing friendly faces again! Alan Draper
