Jim,

To access your engine, I believe Liberty designed the center drawer sections to be disassembled and removed, which allows for access to the engine cover.

This topic came up during a Liberty rally, and it was noted that Liberty has a partnership with the local Detroit Diesel folks. They take everything apart, the DD techs come to Liberty to do the work, and then Liberty reassembles everything. It was mentioned that this process can take several hours for disassembly and an equal amount of time for reassembly.

I have a couple of thoughts:

1. If your engine is running well, do you really need to go through all this hassle? In my last discussion with Detroit Diesel, the technicians advised that if the engine is performing fine, it’s often best to leave it alone. I’d suggest consulting with experts to verify whether it’s necessary before diving into this costly and labor-intensive process, especially considering the risk of getting greasy marks in your coach.

2. If it’s determined that it’s worthwhile to proceed, I recommend letting Liberty handle it. Given that any work on the head of the Series 60 requires access from inside and involves the removal of the interior engine cover, having Liberty oversee the job would ensure that it’s done correctly and that your coach stays clean.

Let me know what you decide!

All:
Sorry. I should have been specific. It is a series 60.

I went 550,000 miles on a straight-six, 4-stroke diesel before replacing the injectors and checking the valve adjustment. The only noticeable difference after all that was I lost 50 RPM!

If it runs well, starts up quickly, and doesn’t smoke, there’s no need to touch it. As someone who works on Detroit Diesels for a living, I can confidently say, “If it ain’t broke, don’t fix it!” Save yourself the hassle and potential headaches unless there’s a clear sign of a problem.

Joe, Toy Box,
It runs well, starts quickly, and produces no smoke.
Jon, everyone:
Embracing my naturally lazy side, I’m more than happy to buy all of you six rounds of your favorite drink as a token of my appreciation for all the trouble you saved me!

And of course, I’ll even include Dale, who, despite his claims of ignorance, still managed to duck out!

Just for your reference, here’s some information shared by some helpful folks from another forum:

Jim,

On our first bus, a 1999 shell called 2001 Country Coach with two HWH slides, we pulled out the dresser drawers and found some screws holding an insert that the drawers slid into. Once we removed that insert, we accessed the floor panel beneath it to get to the valve cover. You might also need to pull up some carpet. We had to take the mattress off the bed for more elbow room, but you may have an easier time since you don’t have a slide.

Jim,

I was in this area this morning. The hatch is 40″ from the left and 37″ from the right, revealing a 21″ wide by 30″ long hatch. When opened, it exposed about three-quarters of the valve cover in plan view. This is on my 1997 Le Mirage 45. I decided to build the bed lengthwise. Hope this helps, Danny.
