timnjulie Report post Posted March 13, 2023 I have a 2005 Damon Astoria 38’ diesel pusher motorhome. It has a 300 Cummins engine that has been diagnosed with a turbocharger that had failed and the actuator will only open 64%, also the manifold gasket is leaking at the #6 cylinder. The Cummins dealer wants $11,000 to repair. The engine runs good pulls a motorcycle trailer with ease. Do I risk breaking down if I don’t get it fixed?

bhalldorson Report post Posted March 13, 2023 If the turbocharger decides to fail 100% it could destroy the engine. I have experience with this and would recommend the repair before going to far. Share this post Link to post Share on other sites
wildebill308 Report post Posted March 14, 2023 That does seam a bit hi for what you said. I think I would shop it around a little. Is this place going to replace the turbo with new? Or just replace the actuator? The actuator is on the outside of the turbo. Look on You Tube there are several videos on them. Bill Share this post Link to post Share on other sites
srsnure Report post Posted March 14, 2023 As a point of comparison, three years ago the turbo was replaced in my 2009 Fleetwood Discovery at a cost of $6,000. It was done by Mainline Truck in Bedford (Cleveland), Ohio. I have no doubt it's higher now, but I doubt it would be $11,000. Share this post Link to post Share on other sites
dons2346 Report post Posted March 14, 2023 Cummins is very proud of their labor rates, parts, and diagnostics. I suggest finding a Cat shop and an independent for second and third opinions. Share this post Link to post Share on other sites

rayin Report post Posted March 19, 2023 I had the exhaust manifold replaced on my Cummins ISC and the bill was #3,000. During this work the turbocharger must be removed anyway, which cuts down the labor bill, so i would agree that is rather high. Locate a nearby HDT repair shop that will work on a MH engine instead of a Cummins dealer, local shops seem to be more reasonable. Share this post Link to post Share on other sites

rayin Report post Posted May 10, 2023 (edited) Cummins Engine location pdf However, if your engine is the ISB 6.7L engine, it is not shown. When you do not supply the needed information, we can only guess. wildbill, there are no videos of a Cummings engine. Edited May 10, 2023 by rayin Share this post Link to post Share on other sites
