We were awake before 6 a.m. yesterday morning to be ready for the tech at Rocky Mountain Cummins to take our motorhome into the garage at 7:30. Since we are not morning people, we were not thrilled about that. And it’s been our experience at different repair shops over the years that even though they tell you to be ready when they open, sometimes it 9 or even 10 before they actually come to get your rig.
But not this time. At 7:30 sharp the tech was at our door and took the RV into the shop. We retired to the customer lounge, which had a TV and comfortable chairs, and settled down to wait.
Four hours later they called me to the desk to tell me that three or four mechanics had gone over the coach from end to end and they were mystified. They had checked the driveline, U-joints, rear end, front end, wheel bearings, motor mounts, and everything else under the Winnebago and could not find a reason for the vibration we have been experiencing on hard acceleration, such as when climbing a hill, or when coming down a hill with the exhaust brake on, or why turning off the exhaust brake on a descent makes the vibration let up. In the process I had them install a new air filter, which was overdue.
Smith Power Products is an authorized Allison Transmission repair shop and is right next door to Cummins, so we went there next and they spent another four hours flushing the transmission, putting in a new filter and Transynd synthetic fluid and looking for anything that might be causing the problem.
When I saw they had an armored car there I asked them if they did so much business that they needed it to haul their money to the bank every day. Or maybe they just knew I was coming.
When I called Mike Bronzi at Redlands Truck and RV the other day, he told me it sounded like the exhaust has a broken bracket and is touching the frame and sending a vibration through the RV. When I first described the problem to Lurch, the Service Manager at Smith Power, he said the same thing, and their mechanic did find one nut on an exhaust bracket that he was able to tighten almost three turns. He didn’t know if it could have been something that simple.
So the good news is that a full day and a $1,000 lighter in the checkbook, we have been assured by both shops that nothing major (and expensive) like the engine or transmission is bad. The bad news is we still don’t know what the problem is. We came back to Cummins to park for the night, with their free 50 amp power, and today we’ll be back on the road.
We had planned to spend a few days in Eureka, California on our way to the Oregon coast, but Mike at Redlands suggested we might want to go up Interstate 5 to Grants Pass, Oregon and have John Henderson look things over. I’m thinking that may be the better option, and then we can cut over to the coast from there. I’ll call him this morning before we take off.
