M100 to TRW Steering Box Swap

[QueenandI]

First time poster, long time information gather. 2001 Monaco Dipolmatt. Getting ready to swap the busted Sheppard M100 PMN31 to a TRW in the Ohio Welcome Rest Stop on I-70 E 2 hrs from home and want to make sure I have everything I need before I head over there. Been in contact with Weller and have the TRW on the way. Multiple sets of directions, some more complex than others. Sockets, wrench, impact, breaker bar, new filters, DexIII, floor jack, hammer. However, from all my gleaning information, I can not find the size of hole I need to drill for the new TRW adjustment. Any ideas?

What else am I missing? 

Side question, is the onboard air compressor belt or hydraulic driven? Can I run the engine to operate air tools or bring my own compressor to run off the generator?

Thank you for being such a great group of very smart and experienced individuals!

in a word, YES.... I have done both, run generator and a portable compressor, and run engine and plugging my air hose into the air coupler near the generator.  Good luck with your project.

Sorry can't help with the bolt / hole size.   However, if you havn't already,  you should get a drain pan because a lot of fluid is coming out when you unscrew those hoses.

I use a plastic tub for mixing concrete from Lowes and a funnel to pour the old oil into the empty jugs. 

Unless you use a creeper I like to find a large piece of cardboard to crawl on, it makes sliding my old body under there much easier.

You can use the coach air system for the impact but an air comp might be a good idea to have along.

A seperaror for the joint on the drag link might be a good idea,  sometimes they are not cooperative.   Harbor Freight if you don't have one.

I would use 1" hole saw lots of oil while cutting

When I had Josam's do the switch on my Windsor they also had to install a new (different) Pitman Arm.

Not sure what a Diplomat would need.

When I cracked a seal on my m80 I was towed to a shop in Duncan, SC. There is no TRW replacement for an M80. They had to use a torch on the bolts to get them out. This is a 2000 Dip. They had it rebuilt and reinstalled it. There is a written procedure somewhere on Monacoers blog on how to do a trw replacement for an M90 or M100.

Good luck

My husband just did the swap, I found a write up someone did for the swap, I’ll attach the file to this post!

I think I used a 2” hole saw for the adjuster clearance. Depending on how accurately you locate it you could probably get by with a 1 1/4” hole.

Thank you for your replies and advise. Yes, I have a new Pittman arm from Wellers too. I appreciate the instructions. It also doesn't give saw hole size to access the adjustment screw on the new TRW, but in the picture it appears to be similar to the mounting holes.
