I have reached that stage in my life where I want to pass on information! (like every other old fart you have met at a tractor show) the multifuel engines had many different tags : white,hercules, continental. When we went to a neighbors retirement sale many years ago I told my dad that someone had put a multifuel in his tractor but dad pointed out that the tractor did not have an intravance unit between the PSB pump & timing housing, also there was no density compensator on the top of the governor housing. The military motors used clear plastic tubing for the fuel supply lines, even the 80(?) psi line that went to the pump head, can't remember if the White tractor had plastic or not. Also it had spin on oil filters & we checked in buying tractor stuff to eliminate our messy cannister stuff. We never converted so maybe we found out we had to change the entire oil cooler assy. $$$ . The first production were LDS 427 then they became LD 465 (non-turbo for 2 1/2 ton truck) & LDS 465 (Schweitzer wastegate turbo 5ton) The other differences between 2 1/2 & 5 ton were fuel delivery, single hole&2hole injectors,cam (maybe?)& stuff like pressure plate, bell hsg. etc. The dry sleeves were slip fit & if you rotated with heads removed the sleeves would usually push out! The energy cell cavity in the piston looks just like a Sheppard diesel & if I recall the Sheppard also had a 22:1 compression ratio. The intake manifolds were a water jacket type & the elbow that the clean air entered in had a spark plug & a tiny fuel spray nozzle, When you pushed the cold start toggle switch it activated a spark box & a tiny 24v gear pump to heat the intake air. When all was good it was actually a effective system. The later were LDT465 with non-wastegate turbo for the 2 1/2 ton , can't remember what the 5 ton had.
