wuss. :-P

Are there any TMs showing these style pistons or any dimensions/wear limits for them? I never saw any, only for the wrist pin hole wear limits. I wonder what the rings are made out of... is the top one chrome? Are new piston rings available for these new style pistons? Any ideas what my issue...

Were you using the front winch and backing up? Edit: I see G helped you find the problem. Fantastic! :beer: I was using my winch once when I was stuck and still had it winding in when I put it in reverse. This caused the transmission to fight itself by trying to provide torque to the winch to...

Does your truck have a sprag transfer case or air shift? Edit: I was thinking of something else but its a 5 ton issue with driveline bind...not applicable to this. Sorry, its been a long day.

I measured the height clearance of the second compression ring and the piston. I measured .010". A quick google search showed me other pistons (not multifuel) that the spec was between .0015" and .003". I have to search the TM's to see if I can find the specs on the pistons. I have never seen...

Injectors all have timing marks so they only go together one way. I have also whitnessed them going in the cylinder heads and they align perfectly. Pop pressure was set to the bosch manual for these injectors.

Why isn't the second ring polished then? What explains the difference in ring gap in the relaxed position? What about the ring dots on the pistons? I am thinking the rings are not in the correct order from the factory and that messed everything up. Other pistons will tell if they are in the...

Oh, I took the top ring off and put it inside the cylinder to measure the ring gap. It measured about .010"

I pulled #2 cylinder... the one that had 95% leakdown. No Broken Rings. Picture 1: The piston ring on the top is real shiny while the second ring is not as shiny. Picture 2: The relaxed state of the piston rings as shown. the top ring measured a gap of about 5/8" while the second ring...

I wonder what the original piston rings are made out of vs what the rings are made out of with the new style pistons? If I pull the pistons out for inspection and find some issue, I will probably end up putting my original pistons back in. I will need to buy a ball hone and from my research...

Looks Great! Any pictures of the full length bed on the M1061A1 trailer?

How does your truck run now? Is it still running good? No Blowby? What fuel do you use?

Thanks for checking up on my G. :-) I just saw this thread now. Yes these 2 ring pistons are not any good as I see it so far. Knowing they are only 2 compression rings instead of 3, that had me concerned from the start. To better clarify what 74M35A2 said, the truck ran good for about a week...

The cylinder heads are the same for LDT and LDS, the pistons are LDS pistons, the injection pump is LDS. The LDS engines are the same as an LDT with the exception of the pistons, injectors and injection pump timing. That is how they get the extra power out of the engines. This weekend we can...

My timing is at the stock setting. Boost pressure is that I develop 15 PSI at 1900 RPM if the accelerator is to the floor... it would develop more at higher RPM but I only spin it up to about 2250rpm.

What are the chances the rings could be broken in my engine? If they were in wrong from the beginning, would they be now ruined where I could not simply just flip them around? The thing is, the truck ran good when I first put it together, and then slowly went down hill loosing power and getting...

I heard quite a bit of them were routed incorrectly. There are threads out there showing the correct way to route them. It does not seem that hard of a thing to check and if they are routed wrong and you fix it, it seems like an easy win. That would be fantastic!

Does anybody have experience with the pistons I put in as far as which way the piston rings go on? Since I have the heads off, 74M35A2 suggested maybe I should pull a piston and see which way the rings were put on the piston. When I got the piston kits, I never took the rings off the pistons...

So what are the pros and cons of each disc? With springs and without springs. The one I just put in my truck 2 days ago is ceramic and has springs.

I was reading something from what Jatonka said a while back about the alignment pins to align the cylinder heads could be sticking up too much and cause issues with interference with the heads. I checked this and all of my alignment pins are fine and do not interfere with the head. I was...
