we have about 100 haul trucks running around, not to mention about htat many in support vehicles, like water trucks, blades and rubber tire dozers, and they all have nitrogen in them. but when a single tire for a haul truck cost anywhere from 50 to 100 grand each, times 6 per vehicle, you do...

i wouldnt like the coversation to change on this thread, but i have seen in my own oa's that my kn filter was pretty useless... it is what they say it is... a RACE filter.

im not sure on that one. We use nitrogen, so the contractor that takes care of the haul truck tires, takes car of ALL tires. i know that they are recaps on factory rims! But they fo thru a set of tires in about 2000 miles on account of the scoria!

WOW! theres so darn much good info in this last post! i knew that about the 5w20, but it just didnt dawn on me about going to a thicker oil to save the cams and stuff... my Boss said whats haoppening is its just hammering the ________ outa the valves, and its dropping a valve and blowing the...

I GET TO WORK IN THE OA LAB TOMORROW!!! i get to learn to run the analysis machines! Ive taken lots and lots of samples, and have been trying to learn to interpret the results, but im finally gonna get to work in the lab! Oh one more thing.. they dont get it... you cant just let them run till...

We have a donaldson contract, and i can get the donaldson filters easier then anything, but i need the time to sit down and see what might fit without it being a hack job. the new 5.4 liter 3v's are going to be easy to put a centrifugal filter under the hood, and keep the factory fitler, but...

i agree. But it IS so hard, and i have racked my brain to try to figure it out. But when it comes down to production, the mining industy's thought is 'get it done no matter what the cost' If it blows up a new diesel engine to look good for some visitors that are investors, soooooo what. Whats a...

We hire about 125 people a month! but we lose about 124 people a month! starts out at 21 bucks an hour. i had a big ol safety meeting today, and i guess we now have about 1200 people hired on here! And out of those 1200 1/3 are people that have been there less then 3 months. thats a LOT of...

I will have the OAs for the strokes posted tonight! One has a new enigne in it, it still has its first oil and oil filter on it.

It is very possible that these vehicles are runing with a totally blocked radiator. not blocked in coolant flow, but blocked in air flow. These roads flip up dirt and rocks, and literally pound the radiator slats closed! and whats not pounded closed gets packed with coal dust. you cant even...

What should a 'regular' silicons be for a 5000 miles oci on a regular everyday vehicle? how come the BG additive has 13ppm of silicons already in it?!?!

i have a few UOA's in on the 'strokes.. it takes the oil sample girl maybe 45 minutes to get me my print out! HA! TAKE THAT! Its so cool to have 2 or 3 personal oil assistants around!!!LOL!

Ok, heres some UOA's One of a 2006 5.4 triton is got acouple thousand miles on it, and its got 1200 miles on this OIC ( the pics i posted up) the other three are base line oil samples, and a BG additive sample. whats up tith all that magnesium, and 13ppm of SILICON?!?! WTH?? thanks guys!!!

Some of the smaller mines run Chevys.. I dont want this to turn into a chevy VS ford discussion, but honestly and coming from a GM guy... chevys last maybe half as long. They crack frames like they were made of glass....., diff housings explode, spring mounts tear off easy, they are just not cut...

Oh dude..... you have NO IDEA!! We CONSTANTLY put brakes, wheelbearings, they break springs maybe one a day F350 SPRINGS!!! We replace all the brakes and shocks about everyother PM, the drive shaft, u joiunts and yolks every couple PM's.. This is a no dooky story... When hummer first got the...

no way to keep track. It would be a literal act of ________ to be able to track whos in what. i mean, just for the haul trucks we have, we had a system called Minestar installed, and it cost us over 3 million dollars, and we had to hire two fulltime employess that fork every day, and they...

ps.. our oil we use is Chevron supreme in 5/20 10/30 and 15/40 diesel oil

compression mught be a little low, but they smoke, and cam and all the other bearings are completely shot....

THANKS GUYS YOU ROCK!!!!!!!
