Why do you guys think that a third battery is necessary? The output of your 12V alternator will be at the same voltage as the midpoint between the two 12V batteries in your 24V system. It is understood that, for the same wattage, a 12V system requires double the amperage, but you are jumping...

Agreed. But you do not HAVE to remove the sprag linkage.

You don't have to do any more than removing the driveshaft.

No need to go any further than removing the front driveshaft.

The evidence "suggests" that they have them but I can't say with any certainty. I have a buddy who has to replace the pan on an LDT1C and he will check and see. I THINK that the only salient feature of the LDS rotating assembly is the cooling channel for the top ring (Continental's paper...

They don't say how or for how long. The last part says that 300hp is believed possible while retaining full multifuel capabilities. That suggests the same high compression and combustion chamber design.

There are five LDTs sitting in my shed. Each one has the external valving for piston squirter. That would suggest that they have the piston squirters. The oil channel in the LDS piston gives a 100F reduction in ring land temperature and was advertised as allowing the use of a poorer quality...

You may be on to something. I had a 302 GMC that would run hot. Ended up being a minor head gasket leak. I ordered a 24V, 16" fan from ebay for $47 shipped. Wanted to try it out and see how effective it would be.

I think that it was the tall hitch which took the weight off of the front of the sled.

Based on Continental's literature, the LD and LDS were designed at the same time for the 2.5 ton and 5 ton, respectively. Based on what I have read here on SS and other websites, the LD received a turbo as part of an effort to clean up the exhaust and became the LDT. In my opinion, calling it...

I'm pretty sure that he was talking about the LDS465-2, not the more common LDS-465-1.

Where do you get all of these improvements? TM 9-2815-210-34-2-1 agrees in that there is additional (though minimal) piston cooling. However, there is nothing mentioned regarding crankshaft couterweights and it clearly states that the the oil pump volume is the same (unless you are talking...

Did these companies replaced the GMC axles with rockwells?

My question is what is significantly better about the LDS. The piston cooling seems minor and was done with the intent of using poorer oils (think about that, oils considered poor in the sixties!). If you had to pareto the multi's shortcomings, it sure seems that the lower end would come...

According to Continental's literature on the LDS, the oil cooled piston results in a 100F decrease in top ring land temperature and allows the use of "lesser" oils. Only 50% of the oil squirted makes it into the pistion. It's not what I'd call significant.

It has a 100kW head. He's testing it right now with a 40hp irrigation pump. Runs great, clear exhaust. Very smooth.

Thanks!!!!

I am helping a friend refit a civilian generator with a multifuel engine and need to know the number of teeth on the ring gear for the speed sensor. It is too far assembled to take it apart to count.

Stumps is dead on. If achieving the CAFE standards were as easy as Lucal oil additive, that is what the automakers would do. Instead, they specify a thinner oil with less friction: 5w20.
