How far do I go with this? etc. 1989 XL CC 8v92TA

Rick,
Just a suggestion, if the bottom of your transmission pan looks like ours then tiny pin size holes are not far in your future. Ditto for the engine oil pan.

Liam, thanks. I am in the process of replacing every ac hose also. Aeroquip has a system called EZ Clip that I am looking at using. That is a project in and of itself, but I think there is no better time to do it. I will attempt to put a photo of the engine on the cart up here. Not sure how to do that yet.

way cool photo. Thanks
-
Rick that’s a great looking portable work cart ,you will know every inch of that baby when done. Good luck .
-
Rick, that picture is priceless now and to the generations of your family ahead . Way to Go and good luck with the project ahead .
-
Would love to see pics of your CC interior if you wand to send to my email.
-
My sons and I have had many great days doing just that! I would love to get the dimensions of that cart. I don’t see an out of frame overhaul in my future but you never know!
Also if you are inclined, post progress photos of your work. Always nice to see how things flow.

Rick,
77 miles north of you in Sheridan, Mi I have had a pretty complete head job done on my 8V-92 by Brandon Peters who runs a shop he calls Superior Equipment Service LLC. He has a lot of 8V-92 experience and keeps a lot of them running on farms, oil rigs, generators, etc.
If you need advice give them a call at 616 835-6525.

Elliot, here are some progress photos.

Is that some $150 per hour mechanics?
-
That’s the same mechanic’s i seam to get, better doin it yourself

Thank you all for the suggestions and information. I am most appreciative.
An update on my progress:
Most of my time this week has been spent in design and looking at wiring diagrams and junction boxes/terminal strips and buying parts/tools/paint.
I have decided to remove both A/C compressors for the Over-the-road air. I am getting rid of the condenser that Country Coach mounted up above the front axle as well as the one mounted over the radiator (dash air). The one above the front axle was a bad idea in the first place. Removing the one on the radiator will give me that much more cooling ability in addition to having the radiator rebuilt with a higher-efficiency coil design. I am replacing compressors with one slightly larger Valeo TM31 compressor and using a roof-mounted condenser. The dash air system will retain the 24V evap fan and 24V evap liquid line solenoid all else being 12V. The galley and bedroom will retain their respective evaporator units, solenoids and controls. I only have to add one relay and some additional wiring to make it work right.
A/C hoses to and from the roof-mounted condenser will go through drivetrain tunnel up into and through a closet to the roof. A/C hoses to dash evaporator will utilize existing copper lines to traverse the bays to and from the dash. Unfortunately the Cruisair condensing units mounted behind the front bumper have to be temporarily removed to access front hoses.
A/C hoses going to galley are simply going to run through the tops of bays 3 and 4 to get to underneath the cupboards. Who will notice? A/C hoses to and from bedroom (evap mounted under bed) are through existing holes above transmission. Not sure yet where to put 30 cubic inch filter/dryer.
That is the plan for now. Not much has changed with motor.
Has anyone else done a roof-mounted condenser for OTR air? I think that will make a huge difference in A/C capacity and radiator cooling efficiency. What do you think?

Well, it has been a long haul, but we are at least going back together on this thing.
Last fall I was able to get the A/C hoses pulled out and new ones run in their place to the galley evaporator and the bedroom evaporator. The two Cruisairs and fan boxes behind the bumper were removed, everything cleaned, ready for paint. Still have to build those hoses and install them. The A/C fittings for the entire project took me a whole day to specify…do you know how many different types of A/C fittings are on this thing? The roof top condenser has been installed with lines running through bedroom closet. That worked pretty well, although you see them when you open the closet. There was only about a 3″X4″ area where it was possible to get those lines through the floor into the drivetrain tunnel. Down through closet over in behind the washer/dryer and through the floor. What a royal pain that was!
The engine bay was sanded down and painted along with the body corners behind the bumper. I think it looks pretty good for a novice. Still need to source and replace all of the rotted out hose tie-downs. Boston Gearbox for fan was a pain. Installed new seals, but the gaskets are not available. I made my own, but had to put it together and tear it apart three times to get the gear mesh right. The gaskets provide the spacing for the gear mesh. The radiator had to be re-cored.
Right now the motor is almost done. Sleeves, pistons, bearings, etc. Injectors rebuilt, heads rebuilt. New oil coolers. Need to set valves and injectors next. Building thermostat housings now…another new tool. As of now, I have about $15k in parts and tools in this project, but I’m glad I did it. I will include some photos.
I have learned a tremendous amount doing this project and would be glad to pass on any information I have gleaned in the process.

WOW! This looks amazing!

WOW! Very impressive. Where did you source the new hoses and fittings for the OTR A/C system?
