Lathe is up and running
I finished building my rotary phase converter , on Monday evening and ran a few test cuts on the lathe Tuesday afternoon .
This is a 0.100 test cut , about as much as the old girl likes .
The test bar is just plain old Cold Rolled steel bar that has been in the shop for a long time
The rust was removed all the way around with about a 0.035" cut .
Playing with speeds and feeds .
Surface finish at about 200 rpm's and 0.027"/rev feed .
Now I can build up the damaged sealing surface on the axles of my 420C .
These photo's were taken with the lathe running and making a cut , except for the final surface finish photo . I bought a better camera

Tools are to men as shoes are to women , you can never have too many !!
Used diesel engines are an adventure any way you look at them !!

Eletrolytic rust removal
I started the rust removal process yesterday on the instrument panel support by putting it into the ERR tank , it is happy bubbling away slowly removing the rust and some of the old yellow paint . Once the rust is gone then it will be time to remove what paint is left and remove a couple of broken bolts before degreasing it and readying it for paint
I have the plans drawn up for the bushing press to change the bushing in the idlers and the track track support rollers . All that is left to do on that is to build it and make the removal and installation tools for the bushings .
I will be ordering the aluminum for them tonight .
Just a little update on my progress . Dan

Just about ready to rebuild the Idlers
I finished building the press to rebuild the idlers and the upper support rollers .
The press was built from drops from other projects and steel I saved from the dumpster on one of the jobsites I was on .
This is the driver to remove the old bushings from the idler . It is turned out of 1018 steel .
This is a 7/8" through bore to allow the driver to be mounted to the ram of my 4 ton port-a-power's cylinder .
It was harder to figure out what to do first then it was to make this driver . I am waiting on a blade for my parting tool to finish it up . I might take it out of the chuck and cut it off in the bandsaw . I am itching to get started on the rebuilding the idlers . Dan

Bushing driver finished and the test of the press
I recievec the blade for my parting tool yesterday morning and set it up .
The cut went smoothly , I used a lot dark threading oil while cutting .
Finish cut , not the prettiest but hey is is just a driver .
Bushing end .
J.D. Tool Number , for future reference
The press works .
Old bushing out , now the idler can be sandblasted .

nice job making that bushing driver,I guess if you have the know-how and a big enough machine shop you can make just about anything.
many years ago an old timer had a machine shop setup to work on indian motorcycles,he could fix or make anything for those bikes.
I watched him repair a hole in a case the size of a coffee can lid,heli arc and a lot skill.
you might be able to start your own antique crawer repair!!!

Installation Driver
I finished the installation driver and I am now ready to sandblast the idler and mounting parts to get them ready for paint .
Installation Driver and Bushing
Bushing on the driver .
I still need to stamp the John Deere Tool Number on it for future identification .
I am also in the final stages of testing of my hopper for my pressure washer sandblaster attachment , I might get it tested today to see if the orifice I made for it is the right size .

Not hard to make if you have access to a lathe . Could make you a set for a reasonable price plus shipping . They would fit into a small flat rate box .Pistonman wrote:I need a set of those.
It has been interesting to say the leastgus wrote:Thanks
I'm about to bring my 420 into the shop and do exactly what you're doing. I think you've saved me a lot of work.....

I have decided that the transmission will get torn down and rebuilt also , since I am this far into it I might as well do the whole thing . Dan

Update.
Well with many fits and starts on rebuilding this crawler I am about ready to get it done. I found the last of the big parts for her and I have to build a few projects before I get started. One a hot tank to remove the nasty grease and dust from the center frame. I might get that started tomorrow . The hot tank has to be tall enough to submerge the center frame completely with the bell housing pointing down. I have a boiler expansion tank here that I picked up off a friend a few years back, I will have to build a set of legs to support the tank above the turkey fryer burner, and stabilize the tank while loading the parts in. I will use a set of chainfalls to load the parts into the tank, the chainfalls will hang off my gantry crane I have here. Once the parts are out of the tank I will pressure wash them and then sand blast them.
I might start on the hot tank tomorrow.
