I really wanted to change the mail bearings too but it was too much work to do that I think. So I just did rod bearings. It runs good. 74M35A2 and I went out to the preview of the Woodward dream cruise tonight. He drove his bone stock M925A2 and I drove the deuce. After I got my truck in 3rd...

I don't have a video of it starting for the first time... I'm sorry. It did what it would do typically if you put on injector lines that were empty... it cranked a little bit and then fired off. Didn't run the smoothest for about 10 seconds and then it smoothed out. I let it run for about 4...

I'm riding the struggle bus tonight. Staying up late last night really kicked my rear end. Come to think a guy that has 10 years on me can handle it better than I can. Thanks for your help 74M35A2! I'm just getting some torque specs and then heading back out to the shop. I hope to have it ready...

If anybody has any questions so far in the rebuild, ask them now while I have it apart! :-)

well tonight i hope to have more done, so relax. I would have had more in before but you thought i should wait until i get all the pistons. :) you need to kick that cold and help me drop some pistons in! :)

I have made more progress on the truck tonight. I checked the end play on the crank and it was only .0085" so that was within spec. The new pistons I bought came with the 2 hole oil nozzles for cooling the piston. So I installed them and that went well. I then cleaned up the top of the block so...

Negative ghost rider.

I found some more wear limits and sizes that would be useful for a rebuild. I wanted to post them so they would be easier for people to see. In the pictures is also the TM which is TM 9-2815-210-34-2-2. The specs I posted below are for a standard size crankshaft.

They came out relatively easy. I rotated the crank so the given cylinder was at bottom dead center. I then took the bearing caps off and used a long piece of wood to go all the way up the cylinder to push the piston up (and being careful the crank does not get scratched during the process). Once...

I agree with the positive pressure all the time on the valves, but what about the non-turbo deuces? I don't think they had valve seals either. Also does that explain the oil/crustyness buildup on my intake valves?

Well the intakes felt good, the exhaust were the ones really worn. These engines do not have valve seals either, which I don't understand why they do not.

I pulled a bearing cap off last night and checked with plastigauge the clearance on the rod bearing of #5 cylinder (it was the easiest to get to). I measured between .002" and .003" clearance. The bearing showed some signs of wear, but it was not scored at all. I have to check the TM and see...

I lied. I am working on the truck more today. I can't help it! :-D I just measured how much slop was in the one exhaust valve of the #3 cylinder. I did my best to measure it with digital calipers and it moved up and down somewhere in the neighborhood of .024" and .030". I measured the valve...

I went home for lunch today and checked my engine to see if it had piston oil squirters for piston cooling, and it does. My engine model on my truck is an LD-465-1 I believe. I will double check when I get home, but I know for sure it is an LD-465 anyway (not an LDT). Piston oil squirters for...

Last night I made some good progress on the truck. I got both heads off and put them on the bench. I also pulled the oil pan to see what things looked like under there. I was also curious as to what rod bolts I had in my engine, 6 point or the latest and greatest 12 point. I don't think my...

It's not a 6-71.... it wont run away :-D

That is the exact thing I am trying to do, document as much as I can and give lessons learned to help the next guy that decides to do the same thing as me. Its a big job so organization and attention to detail is key.

Could a moderator please change the title of this thread to "Piston Rings Worn Out, Time for a Rebuild" I would appreciate it. That title tells more what I am actually doing in the thread and may help people find more answers when they search. Thank you for your help.

Ill have to have my buddy shoot some video. It should be good. Im expecting EGS's to be lower and power to be high. It was a slug before.

I made a lot of good progress with the truck last night. I have a lot of the components removed and did a leakdown test on all the cylinders last night. The leakdown is as follows: Cylinder number 1: 24% Cylinder number 2: 95% Cylinder number 3: 88% Cylinder number 4: 79% Cylinder number 5: 80%...
