Thanks for keeping us up to date. Looks like quite a project! Jim

I am back to working on this conversion project as my move to Oregon is complete. I am now splitting my time between being in Oregon and working on the coach in Gilroy, CA. In addition to doing some interior upgrades, I have progressed with the conversion project. You can select my handle on the FMC website to see other albums that detail other things I have been doing in parallel with the drive train conversion.

Here is a link to the last items I have worked on. You can go back to earlier pages if you have not been following this project.

Cool Stephen!
I remember doing all of that tagging, fitting, refitting, figuring(figgerin down here) & refiguring over & over. I think that I could just about flip to the service manual page I needed in either the 99 or the 2001 book. Used about 15 pads of yellow stickies in the process. It takes A LOT of digging AND weeding out the Lawyer BS that makes up most of the manuals.

Stick with it & keep posting!

Some more steps completed. There is just so many step to complete!!

Here is a link to a photo of the engine essentially "in position". This is a test fitting to ensure everything fits and to position the engine so that the motor/transmission mounting brackets can be designed and located.

The engine will then be removed and the mounting brackets welded into place, final things done to the engine and then the engine will go back in permanetly. The rear frame cross member will also need to revised.

To see how the dash cluster was installed go to the previous page of pictures.

While work continues, I will be gone for the next couple of weeks.

Can you post (or repost) the part numbers to the driveline brake conversion? Was it hard? Thanks!

Actually, I don't have the part numbers. The Allison 540 4sp tranny that I am replacing already had the brake on it and so I just had the Allison distributor move it over to the Allison 1000 when it was being converted from having a transfer case for 4 wheel drive to being a two wheel drive setup. The tail shaft housing must have the provision for the brake. Allison can give you the number for that tailshaft housing.

As a side note, the website that hosts my photos is having some problems as a result of foreign spammers and is no longer available without registering and no longer has the pictures from Dec 2013 to now. When that gets sorted out I will update the pictures and provide a fresh link.

Progress does continue as I am in the process of positioning the engine and tranny so that the motor mount brackets can be welded into place.
