Thanks Verkstad for the info. Since I am new to these trucks and have only seen ours I have no base for comparison. I do feel though that the OM366LA is a nice smooth engine and have been impressed by it. Just also found out that with an injector pump/injector upgrade I can get a bit more power out of the engine (up to 270hp). Also figured out our truck has the 39:8 ring/pinion so there is a possible upgrade to get a bit more top end speed with a swap. All it needs is a pile of money (which I am exactly one pile short right now ).OM352 motor is 345 ci. OM366 is 346 ci.
Substantial differences of design between them.
As much as I like charming oldschool 352s. Given me choice, 366 any day !!
Not sure about that, I know the American way is the decimal ratio (so 4.875). From the EPC and contact with a UK supplier MB does it this way. Guess this way describes the ring and pinion number of teeth (so 39 for the ring and 8 for the pinion)? It seems the American decimal way just describes the overall ratio. Once again, very green about this stuff and trying to learn along the way. I mean, this is not only my first medium duty truck but also my first 4WD (why start small?).Btw, 39:8 seems an odd way to express gear ratio. But maybe not if one cant use decimal numbers.
I probably banded the 1017 into the larger engine group incorrectly and it's not an ideal example of what I was getting at, but what I was trying to simply explain is that the NG, SK, MK trucks are all 'heavier' and 'bulkier' trucks. You are right that the first digit is weight, and in that respect an 1120 will carry more than a 1017. The 1120 is a later truck with a lighter cab and more refined build. If you put an 1120 beside a 1222, the 1120 is smaller, easier to drive, has a similar payload and HP and is probably more fuel efficient... The 1222 by comparison is taller, wider and a little heavier (and definitely more clumsy), making it quite a different truck to own and drive.Hey Sitec, our habitat is 5.3m and almost 2.4m wide. The width is from the rubber fender wells on the front tires. The box length hangs over the rear of the chassis about 300mm (the bottom of the 45 degree angle is at the end of the chassis). Once we got the 385/65 R22.5 tires on our height of the chassis is around 39". For some reason the GVWR of a 1017 and 1120 are the same at 12,000kg (I thought the first digits were the weight rating). Our cab is definitely narrower than the pictures I have seen of the 1017's, but still seems large. Although a little late for me, it would be interesting to see the chassis/axle differences between these 2 trucks as our plans are essentially a land circumnavigation, hope we made the right choice (they all seem pretty robust but I am new to medium duty trucks). We are getting right around 13mpg which I am pretty pleased as the 1120 is full time 4WD. After our cab upgrades and new higher sidewall tires the ride is actually pretty good, not sure how it compares to the 1017. I keep mentioning the 1017 as it was the other truck I was looking into. I bought our truck sight unseen, so was unable to visually compare the 2.
When you say the 1017's have larger engines I am a little confused (happens often). I think the 17's (though not the 917 which uses the OM366A) use the OM352A which I also think is a 352 c.i. inline 6. Our truck has a OM366LA, so a 366 c.i. inline 6. I sort of figured it was just a slightly larger displacement of the OM352, is the block lighter? Now your 1222 has the much larger V6 and they even offer a larger V8. Given that our truck is the only MB cab over truck I have personally seen anything I think I know is just internet reading.
See, now that is yet another reason for my confusion (other than the other more obvious reasons ).Just to add a little confusion the german army had thousand and thousands of 1017,s. I looked at hundreds lined up for sale in several german military sites. They were all plated at different weights fespite all being 1017
Some were as expected 10000 .kg they then went up litteraly in 100 kg increments to about 14000 kg .
Mine is in the middle at 12200 kg .
This is a bit confusing considering that there is an 1117 and a 1217 and a 1317
Work that out
