Dead Cummins ISB/275

Looking for some help with Cummins ISB/275hp in DP motor home. Started normally, backed it out of garage, went to close garage door and engine stopped, just like key switched off. Will nor re-start. Cranks at normal speed, but not seeing any sign of smoke out of tailpipe. Changed fuel filter, checked electric lift (supply) pump, it is running and have fuel delivery when cranking. Any ideas? Also, anyone know how to release spring (parking) brake, as I have no air pressure due to no engine running..so I can pull vehicle back into shop? RV is on a Freightliner chassis, with an electric throttle mechanism. Any suggestions would be appreciated...I can swap for Generator info, as I work on Onan/Kohler/Generac, etc at my work

RE: Coachman Sports Coach DP Question

I purchased my Sportscoach Cross Country new in 2004. Has the Cummins ISB 300 Turbo. I love my coach, great gas mileage usually around 10.5 miles per gallon keeping it at 55 MPH. The coach interior is average but from a mechanical standpoint, I've had no issues.

Cummins ISB 6.7 360 hspwr normal engine temp range

Watching our year old MH temp last night coming home from vacation and I noticed it running at about 201 - 210 mostly at 205 degree. Now it ran going during trip out about 198 - 201 but it was cooler outside, yesterday was 86 degrees - about 10 degrees warmer than the trip out. The fan kicked in around two times cooling quickly to 192. My question is what are you other people seeing with this engine and normal operating temps? It just seems a little hot. According to Cummins it's within normal temps. Fan on is suppose to be around 212 - 215 and engine shutdown at 220. So I'm curious if it was hotter in outside air temp say in the 90's am I to expect much higher engine temps or a fan on constantly? The next worry would be mountain pulling in hot temps. Thanks

RE: Is this a good deal or not?

Thanks for all of your wisdom and great advice. I have passed it on to my husband. We REALLY want a used Ace 27.1 but only after the kinks have been dealt with prior to purchase etc. I would rather have a old Holiday Rambler like that than a newer Ace MH. Build & ride quality is far superior and that 275hp Cummins Diesel Engine is probably a Cummins ISB engine with about 600 lb of torgue. Plenty of power for towing and up hills. The newer Ford V10 only has about 425-450 lb.

RE: Monaco Cayman 34' or Newmar Kountry Star 3353, Can't decide

I'm a first time DP buyer and have reduced my search down to two used coaches both of which are 2004 year models. I would welcome the opinion of folks who know more about these manufacturers. The Newmar 3353 has 2 slides, 62K miles, full body paint, upgraded cherry wood cabinets, new batteries, king dome and two year old tires. The window sticker shows $40K in options for a total sticker price of $182K in 2004. It has a Cummins ISB engine. Overall condition is very good for it's age. Final negotiated price $50K The Monaco Cayman has 4 slides, 8K miles (Yes only 8K), NO full body paint, 3 point leveling system (instead of 4), 6 new tires, new batteries, all the basic features without a lot of others options. Overall condition is good. Also a Cummins 300 engine, not sure if it's an ISB or C. Final negotiated price $56K I see the Newmar as the nicer coach all the way around but the 4 slides and low miles are attractive. WHAT WOULD YOU DO?? Buy the one which is still supported by its manufacturer. (Newmar)

RE: Need advice

Sanford gives classes on digging holes in the road for other cities but they still do not know how to fill them back in. Our roads are rough. Thats why they spend so much money on repaving. There are still plenty of dirt roads, especially in the mountains. Where are you from?? This MH has a thing on the back to block rocks thrown from the tires. Dirt roads don't bother me. By the time I get rid of this MH it will look like it has been through hell if it lasts that long. When we travel we like to explore different roads (dirt or paved) that we see to see where they go. No reservations or appointments so we don't have to be anywhere at a certain day or time. Another reason for buying a MH. Haven't heard anything about the engine or transmission on this one - Roadmaster chasis, Cummins ISB (whatever that means) 340 hp EPA 2007 low torque engine with Allison 2500 MH 6 speed world transmission and Onan 8KW quiet diesel generator. Since I'm not a mechanic a lot of that is Greek to me.

Winnebago 2005 Journey 36G Freightliner Chassis Cummins 5.9 liter engine Driving north on I75 at the Georgia border. All of a sudden the cruise control quit, all of the dash gauges went to zero.

RE: What Alison tranny do I have??

Try looking inside the bedroom closet for the several build sheets; especially the one with the large FREIGHTLINER logo on it. It tells which tranny is in the drivetrain. 2007 Mandolay Valencia 36A Freightliner, Cummins ISB, Allison 2500

RE: Georgie Boy Diesels

GeorgieBoy had a few diesel models. Initially the CruiseMaster which was on the Freightliner XC chassis (Air Suspension). It had Cummins ISB 275HP and Cat 300HP diesel. And was available 1997? to 2005 or 6. In 2000 and possibly 1999 they introduced the Landau, as a Diesel on the smaller XCS chassis (Spring suspension). It used the ISB 260 and 275HP Cummins engines. Both the CruiseMaster and Landau were also available as gas powered on Ford and Chevy chassis. The Landau diesel was only available for a few years as the two diesel models competed with each other, Landau was available then only as gas powered. (After Coachmen took over GBM, I called Coachmen for info on my motorhome and was informed the Landau was never available as a diesel???) There are several Landau diesel owners here on the RV boards.. Brochures and Specs for GBM Diesel.

RE: Looking at new Gasser

We've been looking at a new Winnebago Adventurer 38Q. Love the floor plan and features. Seems less expensive to operate due to lower maintenance costs. Currently have '05 DP with Cummins ISB. Pretty much have a handle of fuel/maintenance costs/trade-offs. Questions are: Will I miss the air bags? Why? Will the brakes need replacing more often? Will the lower torque be noticible? What advantages do a fiberglass roof have over TPO or EPDM? With out airbags you will get a lot of "rock and roll"! Especially around curves.

RE: Class A Fuel Mileage

Over the last 30,000 plus miles we are about 9.5 mpg overall driving about 65 while towing a Chevy HHR. On flat ground out west (WITHOUT a strong head wind) getting over 10 mpg would be common. Late model Cummins ISB engines can get great mileage in a 33-38 ft MH.

What advantages do a fiberglass roof have over TPO or EPDM? Probably, smoother ride. No. Probably not, if you drive conservatively. Both the same, many will argue fiberglass is better but unfortunately there is no real proof, just opinions.

RE: Synthetic oil change-over

I had to do a little research on this because I run a Cummins ISB and wasn’t as familiar with Cat. From page 15 Table 6 of the Caterpillar on-highway diesel engine fluids recommendations guide dated November 2009. This is the newest one I could find. SAE 10W-30 is the preferred viscosity grade for the following diesel engines when the ambient temperature is above –18*C (0*F) and below 40*C (104 *F) C7, C-9, C9, 3116, 3126. This chart also shows a 5W-40, 10W-40 and 15W-40 as being acceptable. Also hear is what it has to say about Synthetic Base stock oils. Synthetic Base stock oils are acceptable for use in Caterpillar engines and in Caterpillar machines if these oils meet the performance requirements that are specified by Caterpillar for a particular component. The highest level of protection is Cat ECF-3 or API CJ-4 oil category performance requirements. On page 17 Cat does say if you do the proper oil analysis you can extend the oil change interval. The diesel engine operates at much higher internal temps than a gas engine. It is only because they have much bigger cooling systems that they will run at the proper temperatures. You can do a search and find a large number of posts about coaches over heating. Most from dirty radiators. When I see EGT temps 1200 deg + when pulling a long hill I am glad I have oil that will stand up to it. I also like to get oil to the turbo as fast as possible and to give it maximum protection. The oil today is not the oil of our youth. 50 years ago I would never run less than strait 30 weight oil and never one of those new multi grade oils. Today I run Mobil 1 5-40 Turbo diesel Truck. This oil meets or exceeds Caterpillar ECF-2, ECF-3 and also meets API CJ-4, CI-4 PLUS, CI-4, CH-4/ SM, SL, SJ. Bill
