Thanks for the comments, that's mine and it was indeed a fun project. I know I've said it before, but sometimes I think I spend more time propping stuff up for photos than I do working on things. I also want people to know if it wasn't for the help of people that know these old machines the projects would be difficult at best, I try and post some of the stuff I've learned during the process.
My first machine was my grandpa's WC in 2004 and I had no real intention of restoring it, I just didn't want the barn to fall on it. I must say first that I have been blessed with this hobby. Every step where I didn't know what I'd do or how to proceed, I'd meet or be introduced to someone that did. Being a computer network guy, I Googled Allis Chalmers and found Tony Carbaugh - he helped me out on several things and lined me up with others when he didn't have what I needed, and got me started on this forum.
One quick story comes to mind. I needed a final drive hub for the WC - mine having teeth all chipped up. I called Tony and he lined me up with Bill Deppe I called Bill on a Monday and on Thursday afternoon the back half of a WC was in my driveway all the way from Maquoketa, Iowa, and I only needed to pay some gas money for freight. It turned out a brother of a co-worker of mine was coming through that way with a vehicle that could haul it.
I have had other very eventful coincidences too. But this post will get too long. The brake pin puller is made by Gary Agrimson http://www.agrimsontool.com/ac.htm - http://www.agrimsontool.com/ac.htm
He also has been a great help to me, I don't hardly want to start naming people since I'm sure to forget some. Dave Ferguson taught me everything I know about the WD45 Diesel injection system and should get named for sure though.

So Tom,,,did you find the brake pin puller as effective as it looks?

Yes, it was very effective. I pulled the ends off first though as I described on my web page. I think I could do it better now that I know how though - well since I haven't had to in a couple years who knows. You have to know that it has the ability to pull the ends straight off. You have to make sure the shoes are loose and work them back and forth, I actually think the shoes were stuck to the pin more than the pin was stuck in the hole. I could pound the pin in and get it to move out a bit prior to pulling the ends off. Once that was the predicament I had to drill and tap a hole and get a washer ground to the right size to fit the tool again then spent more time working the shoes back and forth while pulling with the tool. Many have said they have gotten them out with a little pry bar but some are so rusted in place you almost need to blast. Tom

Thanks Tom!,,I need to look into my WD's brakes and I messed with them last summer a little and the one I messed with wouldn't budge!
Dale Haymaker has told me several times,,,they'll either come right out!,,,,,or you'll fight them to the bitter end,,,,,,
What's your opinion of "neversiezeing" the pins before replacement?,,,Dale and I have talked about that possability too!

I put no sieze on my new pins. I hope to never have to do a brake job on it again but maybe someone will appreciate it.

since when did a 45-d use shims in the rods and mains????

My uncle told me as soon as I bought my first 45, to leave a can of whatever penetrating oil you like in the tool box, and whenever you think of it give the pins a good shot. then when you get around to it, they might just be freed up, especially if you are using the tractor and working the brakes. It worked for me but i never checked them before I tried to remove them.

Thanks for the extra effort to take lots of photos during the rebuild process...and a special thanks for orrganizzing them and sharing them with us. I also use a lot of never-seize on bolts/pins when reassembing; great stuff for future tear downs...and to find out where your hands go.

Yes, anti-sieze does seem to get on fingers and then leave traces where ever gets touched, and usually you need to touch lots of stuff before you can really clean them.
As to the shims mentioned, I don't know why there were shims under the rod bearings on the engine I purchased. I suppose the idea was to tighten them up a bit. Since the reason that engine had been sitting on the gravel floor of a shed for several years with no pan and head was because a rod bearing had spun, I can't think it was a good idea. There were no shims on the mains just the rods. In any case there are none in it now.
Thanks for the comments. Tom
