Thanks for the imfo always wonder about the L DS - 465 -2
Steel Soldiers now has a few new forums, read more about it at: New Munitions Forums!
Yeah, thanks for the info about the LDS-2. What was different about those, as compared to the LDS-1? That cyclone-type air filter is very similar to the Sy-Klone pre-filter that I'm going to mount on top of my snorkel. Not going to increase airflow, but should help keep the air filter a lot cleaner, and flowing more air. Not going to worry about feeding my LDS any more air until/unless it's a problem.Yes, they were built exclusively for the 1969 m656/xm757/xm791 8x8 trucks. Very few in existence...
The air cleaner on these trucks is of a 2-stage type, where fins or vanes set up a cyclone effect on the air to separate heavier particles, which are collected in the "dust pot" shown in the images and that was 40 years ago.
Don't think you'll notice much difference in the performance with a different filter unless you operate the truck under near full or full load.
To measure the efficiency of the filter, install a "vacuum" gauge and look at the readings for the different filters. Third image below shows the gauge I have in the M35 and it indicates about 3 to 4 inches of water mostly.
The restriction indicator on the dash, by the steering wheel shows red at about 20 inches...
K&N filters are a no no, Lucas is a no no, slick 50 is a no no. synthectic oil is a no no, letting an engine idle to warm up is a no no, using the phrase "no no" is a no no.k&N filters on any turbo diesel is a no no

Oh wait, I mean they are all awesome!
For every engine that supposedly blew up because of one of the above one was supposedly saved by one of the above.
For EVERY OPINION on any of them there is an opposite opinion, some actually even show so called FACTS and INDEPENDANT lab studies. I saw it on T.V. or read it online so it must be true. I know this guy who is an engine builder by trade and he swears by/against it so it must be true. On and on and on.
Thank you for the detailed write up and pictures recht71your info and effort is appreciated
Cummins made a statement on their website specifically recommending AGAINST using KnN type filters. Good enough for me.you may be right on that sir, although i have yet to hear any diesels techs say any of what you mention is a no no. They do however show how reusable k&n's allow lots of dust and dirt through more so than other diesel filters. i ran a k&n on my old dodge 12 valve for a few years until i started noticing the excessive amounts of dirt and grit in the intake boot.

It was on one of their European web pages. I found it several years ago but could not recently.Where? Can't find it.
