Re: JD450C third head gasket This is getting old

Thank you Bruce for your post. I was concerned about thread failure. I will get better threaded shafts later if it does. I have been trying to decide how far to take this repair. Given the slop in the timing gears, the slop in the balance shaft bushings, and the general wear including semi slow buil...

Re: JD450C third head gasket This is getting old

Got home and started in on making a puller that will hopefully last a good long time. If all goes well it will hang there on it's pegboard hook after I am done and get real dusty. :wink: So I made this. Three choices for allthread. A single center if it is not a hard pull, or dual allthread for a to...

Re: JD450C third head gasket This is getting old

Well at the risk of making yet another longer than neccessary post yesterday (I'm good at it :) ) I stopped in and had a 2 hour conversation with the John Deere guy I mentioned was the go to person for John Deeres around here. We talked about JD's and airplanes. He had a couple suggestions on gettin...

Re: JD450C third head gasket This is getting old

I never had plans to save it. Especially after seeing it with the piston out. It is actually worse on the opposite side from the picture. So I made a puller that I am trying to post a picture of. Paint won't let me save the resized pic. I used a 3/4 or so thick bar and used two coil spring compresso...

Re: JD450C third head gasket This is getting old

I will try that Jim. Thank you. I did try about 5 good whacks with a big snap on slide hammer 3 jaw puller. I decided to quit so I did not damage the OD of the sleeve. I see the liner puller in the manual. I will try the sledge on top idea, and then probably see about building a puller to try and ap...

Re: JD450C third head gasket This is getting old

Thank you for that. The seller said it was a 78. Pretty hard to purchase a 78 in early 76. :mrgreen: So what is the secret for removing a stuck liner? I definately need and in frame rebuild. The liner looks pretty bad with coolant etching and scoring from running it with the corrosion that was creat...

Re: JD450C third head gasket This is getting old

Interesting stuff developing here regarding all this this morning. My next work project has been canceled. The owner has developed cancer and his life priorities have changed. Restoring an old jeep is not in his cards. Disturbing news. I spent more time awake last night than asleep. I too pondered h...

Re: JD450C third head gasket This is getting old

I had a heavy equipment mechanic friend come by today to borrow my log splitter. We took a long look at the engine. I showed him everything I had found. He thinks the block is damaged and the packing land or ridge? is broken for it to be so low. The opposite side of the liner is high. So it is defin...

JD450C third head gasket This is getting old

I have not been on here in a while. I finally got caught up on a project and got it to it's owner. One of the things waiting for my attention is my 1978 JD450C with turbo. I am about to do a third head gasket and I am looking closely to try and not have to do this again. I have found a liner low on ...

OK, I was not sure it made it. And my internet has been down since this morning. Blue skies too, which is unusual.

Thanks.

Compression testing

Happy new year all. Working on a 1978 450C w/ turbo. And a 1969 JD 400 backhoe. I was going to ask about a part # for the correct adapter for compression testing. I believe I have finally found the correct one. http://www.autotoolworld.com/Mityvac-MVA5619-Diesel-Injector-Adapter-JI-Case-Caterpillar-...

Fantastic that you found a good solution for new instrumentation. The Stewart Warner Deluxe series have always been a favorite and go in most all my car or jeep restorations. Only recently did I open a SW gauge and found the gauge face was crimped out of position and could not be mounted straight in...

Grab a flashlight and remove the seat and covers and give the shifter some movement. I did this yesterday on my 450C as I am getting ready for some adjustments and was surprised at how sloppy the linkages were. I have clevis pins wore half way through and the lock nut under the clevis for the shifte...

I just received a thermostat from John Deere and got it in yesterday. Drove it today and it is great. Solid at 180. I tested the old 180 thermostat in a pan with a temp gun. It did not start to open till it hit 205 and was slow to open. It was fully open at 213 or a boil. Hmmm. I shut the motor down...
