You're welcome!Thanks for sharing!! Great info!
Golden rule, I suppose.Our new friend has great advise and is willing to help when others would walk away .. Ty sir!
The basic architecture of these engines has been around for a long, long time, and they're solid. I'll have to respect those that designed the thing and wrote the book. Now, for practical real world solutions, you have to fully immerse yourself in it for a while, and that's when you figure out all the quirks and working solutions that aren't in any book. Quite a few of the technical bullitens were put together from collaborations between individual mechanics and technical service managers, who worked to gether to pinpoint various problems. I like that level of troubelshooting.I especially like the comment of "follow directions".
I have an older sister. She knows how to drive a stick shift. That's pretty much where her automotive knowledge ends, though.Greasytshirt,
Do you have a sister, that works on Freightliners ?
She'd be a welcome addition, too.
I think they are very good trucks. I'm not sure if they're even making large cabovers right now, if they are I haven't seen any. The little NPRs are hard to beat at what they do. They suffer from some of the same things that little Hino cabovers do. They also have their own quirks. For example, It's hard to bleed air out of the cooling system, so if someone refills the cooling system without burping it, it'll spike up in temp pretty quick. The placement of the EGR coolers on the newer ones make this worse, and the temperature differential of hot exhaust gas on one side and air pockets on the other makes them crack. You'd need a vacuum operated cooling system fill tool to make it easy. The oil coolers seem to leak oil into the coolant after several years of use. It's a hassle to get it out, because it's on the fuel pump side of the motor and every thing is in the way. The liners are no where near as easy to get in and out like on a Hino, and replacing the main bearings while the engine is in the truck is absolutely impossible. The block splits at the crank centerline, so the engine has to come out and go on a stand, and the block halves separated. It's kind of a pain in the rear.What's your opinion of Isuzu ?
That's a good question. I've actually heard that too, but it's always in passing, like an urban legend. In this case, we would not be able to do anything with it, as it's going to be a function of the Allison ecu. We can get in there with Allison software, but reprogramming lies in their hands. If you call an Allison shop with the serial number, they should be able to tell you exactly what it's got.coalminer said:I have seen someone say that the dealer can "unlock" the 5th gear, so my question is, that actually 5th gear or one of the lower gears that is "locked"?
