RE: Which of these 3 battery brands would you choose?

I just replaced my batteries with 6 of the Trojan T-105’s. Paid about $136.00 each at one of the local golf cart stores…..be sure to buy a battery strap to pull the old ones and replacing the new….sure makes the whole process easier. They are heavy…. All the research I did….pointed to the Trojan as the best. Also agree with earlier post….they are wet-cell.

Follow up- Turbo goes out at 37,000 miles

One more peculiar thing……before my turbo went out I was getting about 7.8 mpg. After several trips (350 miles) after the new turbo and actuator were installed…..I’m getting 11.4. I know that is a very short number of miles to get a real number for mpg….but I never got that kind of mileage…comments?? And yes, I know there isn’t any way that RV towing a Tahoe should get that kind of mileage….

RE: Turbo goes out at 37,000 miles

Yes, you are right about it being too late. I had talked with Cummins and they indicated a failure analysis could be done which would very likely provide the cause…..unfortunately Freightliner had already pulled it and sent it back as a “core exchange”. The actuator was bad and had to be replaced as well…..the Air Filter was replaced along with complete service on the engine and chassis. I’ve learned enough from this incident to make sure of what to do if there is a next time…..

RE: Turbo goes out at 37,000 miles

I got in the internet and found 2 sites that are worth looking into, the first one is really good in explaining the different pumps and their pitfalls really worth reading, the second one is good to. Hope this helps a little www.rbracing-rsr,com/oilsystems.htm www.team-bhp.com/tech-stuff/idling-rule-turbo navegatorl Thanks!! I will read them…..the URL’s make it easy !

RE: Turbo goes out at 37,000 miles

Maybe someone can impart a little wisdom.....I have a Tiffin Phaeton (only 37,000 miles) with the 8.3 ISB, with 380 HP and 1250 foot pounds of torque. Just a quick correction-- the Cummins 8.3 liter is the C engine-- depending on year it would therefore be the ISC. You are absolutely correct, you win the gold star for the day !! Thanks for the correction….

RE: Turbo goes out at 37,000 miles

One item that kills a turbo really fast is driving down the interstate at full speed and getting off to get fuel, coming in to the gas station and shutting down the engine. This simple little action is detrimental to the life of the turbo, while the engine is running the oil is circulating to the turbo and lubricating the bearings and cooling, shutting the engine down shuts the flow of oil, this oil not only helps lubricate the bearings it also helps with cooling the unit. When the flow of oil is interrupted the residual oil begins to cook and slowly starts to block the passages and also starts to destroy the bearings. Depending on the turbo, it will spin at about 17,000 RPM at idle and anywhere up to 150,000 RPM's running down the road. Try to avoid this by letting the engine idle 2 to 3 minutes or more before shutting down, this helps the turbo slow down to near idle speeds and helps cool the unit a bit, this prolongs the life of the turbo. I do not know if they still manufacture them or not, it is an electric motor 12vdc and a pump coupled with a timer that runs for about 3 minutes at engine shut down and pumps oil to the turbo after the engine is shut down, totally separate from the engine, runs from the engine sump to the oil line for the turbo, the oil then drains to the engine pan this helps cool down the hot end of the turbo while it spools down and prolongs it's life. navegator I have made me a small white laminated sign and Velcro’d it the dash.......it says: 5 Min Cummins recommends a 3-5 minute cool down before shutting off the engine. I have been guilty of this in the past....never again.

RE: Turbo goes out at 37,000 miles

Bad turbo? Indeed....replaced the Turbo, turbo actuator, NoX sensor and did all the yearly maintenance, service, coolant flush and change, etc...|

Turbo goes out at 37,000 miles

Maybe someone can impart a little wisdom.....I have a Tiffin Phaeton (only 37,000 miles) with the 8.3 ISB, with 380 HP and 1250 foot pounds of torque. I maintain this thing as it should be, even have it stored in an enclosed facility. Driving down the road several weeks ago, the check engine light comes on, then the stop engine warning...I’m on a very small one lane road....before I can find a place to get out of the road, it goes into limp mode (derate the engine) and just a very short distance later.....shuts down. Coast onto the side of the road and that’s it.....tow to a very large Freightliner dealer where I get the bad news. I bought this baby brand new and maintain it like crazy. Any guesses as to what could have caused this??
