Okay, so they tell me that if I shut the truck off, it won't start - or is real hard to start. Something about losing it's PRIME. Been in the FL shop for days and they can't figure it out. New fuel pump didn't help. Using a "bypass" fuel line didn't help.

Any suggestions from the REAL mechanics???

If U can't help understand the problem.... how about this? If it accidentaly shuts off on me on my next trip... HOW would I manually prime it to get it started?

Thanks!

I can't say much but those Benz engines are very poorly understood by mechanics here in the states who were born and raised on the big 3 American ones. I think your best bet would be to find a Detroit Diesel shop with a mechanic who specializes in these at this point. Detroit is the one who is supposed to have the people capable of the service on these but even with them it is hit and miss....

Engines are engines ;0) learn to fix 'em!

The ISX replaced the N14, the 3406E (C-15, C15) replaced the 3406 pushrod engine, the only 1 that's still the same is the S60, and it's hardly recognizable along side of the new ddec IV engine. Rumour has it the S60 is going away for the '10 emissions platform. All of the others have been changed-out by new/updated engines.

Cat, Cummins, and Detroit will all become optional engines in the near future.

Get used to the Truck OEM specific engines;

freightliner/sterling/star - MBE,

Navistar and Paccar both have a big-bore engine coming next year for their chassis.

Volvo and Mack of course have their own engines.

CAT and Mercedes both have drivelines (trans/diffs) for h/d trucks as well.

Peterbilt has also announced the introduction of production line hybrid trucks --- nothing's gonna be the way it used to be ... ever again, unfortunately.

There's my rant for the day...

Paccars engines will be rebranded Cummins for the time being anyway.

The '07 medium duty's are cummins engines with paccar badging... no more yellow-powered mediums.

thanks for the replies. Actually FL took it to the Detroit place down the street. THAT's where the mechanics are still puzzling over it for 3 days now.

Wish me luck as I'll be taking it coast to coast this weekend, and it's REAL COLD out that way. If it shuts off, it won't restart. B-r-r-r-r !!!!

Will it start on ether?

If it's under warranty, and they cannot fix it... ask them for a can of ether... you know, just for the reaction ;0)

...you should consider all of this next time you go to buy a benz, all I hear about is mechanical issues and low power complaints... all to save a few bucks on a truck with no re-sale value.

The trouble with the Europeans and their products is that the mind set is more geared toward the institution be it the government or large company and the authority thereof. For instance I was taking an Allison transmissions class last spring from a guy who also taught Detroit Diesel and hence, Benz engines. He was talking about one thing, I think it was a fuel pump drive gear, that backed off its bolt and took out the motor commonly, due to a bad design. He brought this up with the company and they seemed taken aback that any grease knuckle mechanic should be able to tell their high class German engineers to do anything differently, after all, they were the ones with the fancy degrees! I have also noticied this with the new disc brakes of European design. They want all sorts of expensive special tools just to do regular service sometimes because they expect it will be taken back to them for service where here in the states we are used to a brake than ole Joe Bob can fix with nothing but a Budd socket, a pick, and a big pry bar. So my advice is before you buy anything European in origin, find out the details about service availability, cost, and track record.

i'm understanding that euro truck mans have already been using disc primarily for many years. don't forget that the american manufacturers are already pushing disc brakes here... hard.

furthermore... the old 16 1/2 x 7 brakes are going away shortly, larger brake shoe tables are required to meet NHTSA's new brake stopping distances.

The Europeans certainly have and they have been paying through the nose to get them serviced as well. But they are used to that so they apparently don't think much of it.

They are pushing them here but I have asked some mechanics about them and they say that they are nothing but trouble so far.

furthermore... the old 16 1/2 x 7 brakes are going away shortly, larger brake shoe tables are required to meet NHTSA's new brake stopping distances.

I have been informed that there will be some 16.5x10 or 11 drums available that meet the requirement, as well as the discs of course. What's the solution? I don't know but I do know that here shortly it will be a bad time to be buying new trucks.
