2007 Freightliner Columbia MBE 4000

for your excessive crank/no start problem.change the timing sensor on top of transmission bell housing.only $30.when you pull old one it will have build up of clutch dust.does not always throw code.good luck.

 

sorry.meant to say sensor is in top of flywheel housing not bell housing.

I'm typing this on a phone, so I can't access your list handily.....

Hard starting/long crank: I had the same symptoms with the original motor but the new reman engine seems to do it less often.

Speed/cruise lag time: I just recently had mine limited to 65 as well as I thought I was going to reload in ON. I went through the screens with the mechanic and thought we had it right..... Result is mine lags as well, drops a few MPH and then picks up again. I'm sure it's in the settings as it hasn't done this in the past as I recall. There are options for driver rewards with MPH for MPG in there.

Does it do it at a lower set speed as well?

Smart pass was an option I saw in the various screens.

Oil PSI: mine is just above 60 but cruise rpm is 1450, so your psi would be lower at a lower rpm.


Check engine light: on a Columbia, it can come on separately from the engine ECM. There are various posts about the PDM in the drivers side door post panel causing this. Look in "the garage" under Freightliner forums.

What rpm do you cruise at?

 

Thank you. I'll investigate into it a little further. It may be the culprit with the random code throwing as well.

I'm wondering if the reman just happened to come with a new timing sensor, or it was at least cleaned in the swap process. I'm thinking we might just pull the old one, clean it and see if things improve.

That's why our company has ours set as well, just so that it's Canadian compliant, should we go there. Technically they are set to 64.5. I'm wondering if you set it to 65.5, you now become non-compliant.

I'll have to experiment with it by setting the cruise at a lower speed. I typically only run it at max setting, and don't set the cruise at say, 55. I'll do it tomorrow on my run.

I think Smart Pass is a great feature. Drove for a company in Florida that had it on the 60 Series and it came in handy at times. I used it as intended, some guys would just burn through their allotted hour - which was redundant.

I'll poke around over there next. I'll give you a better answer on oil PSI tomorrow. In fact, I'll hit 1450 and let you know what mine is doing. I know that there are variables - you may use a higher quality oil then our shop does - I've even noticed a slight increase in PSI when you put a gallon of Rotella in it on the road.

 

The reman motor was complete from crank pulley to flywheel and housing and fuel system to turbo, so likely all those sensors are new as well.

I'm using Delvac, mostly because I'm a slave to marketing, LOL.

I did use Delo for a long time because it is found in every shop where I live and I was home for every oil change for many years.

 

A truck with any engine of that many miles. May have many problems. But then it is al about what u can afford and what u can do about it..

 

Curious. What was the out of crate price tag for the reman? Because if I purchase the unit at some point, I think I would opt into one just for the reliability. I'm fairly pleased with the little powerplant.

It's not my tab to pay, but our shop does have a budget like any other operation in trucking. So, yes, we would clean the clutch dust off the sensor to see if that works. If not, we would replace it. I have many friends who have run engines to 1.3 million miles before an inframe without it chucking it's cookies. It's a solid running truck for it's age. Slightly tired, but then .... so am I. All those miles have given me problems too.

 

I wanna tell U top secret information:

THIS SENSOR IS WABCO ABS SENSOR but with different connector.

U can install ABS sensor on its place. Just nock it in. The only problem that polarity is important so when U start engine it may fail to start ore run rought (with fault code) if polarity is wrong, so it is ez to change polarity twisting wires.

On early MBE engines they used no connector on sensor. There was used ABS sensor with long wire connected directly to 55 pin connector

 

Make sure "soft cruise" is NOT enabled, as far as the speed dropping. It was meant to be more fuel efficient, but ended up being a royal PIA.
Now you Canadians can send me some Flakes and real vinegar for my chips please

If the sensor is part of an integrated wiring harness, it would be an OEM drop in. We're big on maintaining integrity of factory wiring. My additional lighting on the truck is junction boxed at the tail-lights, just to not hack into the front wiring harness.

Thanks. Yeah, I don't mind 65, but it needs to hold a solid steady 65. I can't see where this continuous cycling between 63 and 65 saves fuel. Plus, it's annoying as crap to pace traffic with.
