I can in fact confirm that neither the cab nor camper of the ER need to be removed for the engine to be removed for service:
I recently had the misfortune to experience a catastrophic fuel injector failure. The tip of the #5 fuel injector cracked and within perhaps one hour of engine operation at low demand the tip broke off and bounded between the #5 piston and head:
New #5 piston (shiny):
Here is the expert care provided at Diesel Services, Inc. in Grand Juntion, CO - an absolute FANTASTIC service center:
Yes, the engine comes out without cab removal:
I am happy for Rob and Nina in whatever vehicle they choose to explore - a belief I share for every adventurer on the forum or who hasn't discovered the forum yet.
I happen to believe that there is a bit of a tinkerer in Rob and he is - much like me - compelled to always work on things. I suspect he will always be in search of a "perfect" exploration vehicle...perhaps that too is why I have invested so much time in trying to get a 1972 Russian KMZ "Dnepr" MB650 motorcycle into running condition...:
There is another fact - ******** and Pip Smith had their (my) ER serviced overseas in an austere environment without the benefit of cab-off facilities TWICE. This is chronicled at length in their blog (accessible through the link to ER here:
http://earthroamer.com/ on the tab labelled "EarthRoamer Around the World"). Once for a transmission leak in Ulaan Baatar, Mongolia (11 March 2008) and initially for the high pressure oil pump (HPOP) at the snap-to-connect (STC) fitting while in Almaty, Kazakhstan in October 2007 (a weak point identified - and corrected - by Ford due to a high rate of failure):
In the picture above, ******** Smith is holding the old STC fitting and fuel injection oil supply tube (Ford's 6.0L uses high pressure oil from the HPOP to cycle the fuel injectors unlike common-rail which uses high pressure fuel).
It can be uncomfortable to lie atop the engine bay (I did just this for several of the modifications/upgrades I've performed)...but service is possible. Granted, parts availability was an issue but I hazard that ANY vehicle would have been difficult to obtain parts for in Mongolia; the ability to repair rather than replace would have been a beneficial alternative of course. On the Turtle Expedition across Siberia Gary Westcott said, "Cost was never a factor" in the search for reliability and his objective was "simply to find the best!!" (

The Land Cruiser's diesel is just not powerful enough for a large GVWR vehicle - this is not a fair comparison. Certainly there are non-electronic diesels available and they are well tested but considerable effort and expense goes into any expedition preparation - that expense may not be measured in currency but in man-hours and physical effort...an investment nevertheless.
Sometimes though, field conditions don't support an individual attempt at repair. In my case, I was concerned that the copper crush washer for the #5 injector would come free from the injector and fall into the engine resulting in the same catastrophic piston and head damage and perhaps putting my engine block at risk of cylinder wall scoring (and total engine destruction). While my dismay at the time was poignant, my decision to recover the vehicle to a capable service center was clearly the appropriate choice.
...and I say this with certainty...
EarthRoamer and fellow ER owners stood with me and helped me in a way that is beyond description and speaks (silently) to the character and values of these wonderful individuals and the organization. I am not implying that Unimog and the Unimog community won't similarly respond but my own experience was humbling and inspirational.
I am proud to be a part of these groups. I am blessed to count Rob and Nina as acquaintances - and I hope as friends - and I look forward to learning of their adventures in ANY vehicle in which they choose to explore. I am certain we all can continue to benefit from the discussion without reverting to a flippant comment such as how overly complex modern engines have become...
...excuse me while I search for my carburetor-voodoo-brew-guide to balance the cylinders on the Russian copy of a WWII BMW boxer engine...how nice it would be to have some modern features like a fuel gauge (...yes, I ran out of gas on a ride...at least there is a 10L "reserve" can...still I had to coast off the road...), or an oil temp gauge, etc...not all that is old is best, not all that is new is bad.
You can really go far in an ER - but avoid engine-out service is good advice if I may offer it (wink).
