No adjustments, but the owners manual says a major overhaul of the motor is needed @350,000. Not sure what that consists of.

 

well then i gots a ways to go, "major overhaul" is complete engine rebuild according to my teacher. Thanks for the information guys!! =D

 

the PSD uses a hydraulic lifter which doesn't require the valves to have the lash adjusted. the hydraulis lift is an automatic adjuster of sorts. the reason you need to set the vavle lash is because those engines all have solid lifter which wear along witht he push rods and rocker arms. that wear makes the gaps get larger therefore needing periodic adjustment.

 

So is there even anything to tune up or do if i have some free time and not enough money to go buy new parts and stuff?

 

only "tune up" stuff would be fuel filter every 15k, air filter when needed, oil change ever 3-5k depending on usuage and filters, and glow plugs when they go out. These pretty much just have maintence and not tune up's.

 

There are always maintenance items that need to be done on these trucks - for example: clean screen and shim FPR, check all air line clamps and tubes to make sure air only gets to turbo through the filter, clean valley on engine with degreaser and air pressure and look for any fluid leaks with flashlight, check all under valvecover wiring connector clips to make sure they are clean on the inside of connector and firmly connected, check auto tranny fluid for clean-ness and level, check ZF stick tranny for fluid level, jack up front of truck and wiggle,push,pull,pry whole front end to see if there is any play in any of the suspension or steering components, while front is up put transfer case in neutral and engage hubs and spin front wheels using the driveshaft by hand to see if there is any binding in any of the in-line parts in the axle, service front and rear differentials(remove covers, clean out and refill with new gear oil), of course grease all zerk fittings on the truck as often as you change the oil or everytime you go in water, jack up rear of truck and adjust rear brakes with brake spoon or screwdriver through slot, maybe even pull the rear wheels and brake drums and have two cans of brake cleaner on hand so you can spray,brush,wipe,clean out the brake area and also lubricate the three rub areas and the adjuster threads with lithium grease to keep your brakes working tip-top, pull VSS off top of rear diff and clean it off and put it back on, check all lights on truck and make sure third brake light is working up on top of cab, lubricate all your door hinges and check your door latch posts to make sure they have the little gray plastic bushings on them, check all battery cables and connections for clean-ness and tightness, check your coolant for SCA's, clean out the insides of fenders and bottoms of bumpers and spring perches and tops of fuel tanks of all mud and road debris, check a couple of lug nuts on each wheel, and just spend time checking her out. I guarantee that if you do all of these things you will be surprised by at least one thing that you find along the way and you will be much better acquainted with your truck, you'll have more peace of mind and you may even possibly avoid a major problem that may be developing unbeknownst to you. You don't always have to spend money to improve and work on your truck. Oh yeah, go ahead and check your tire pressure and make sure they're all correct. It helps with road handling, braking, load carrying and fuel economy. While you're under there, check them all for nails or damage or uneven tire wear, too especially in the front. If your rears are really flat and your fronts are rounded, side to side then rotate them front to rear and vice-versa. The owners manuals have a lot of good information in them too. Reading/studying them can make you a better and wiser owner/operator.

 

Thank you so much!!! Wow! I've got a list of stuff to do, i didn't even think about half of the stuff u took the time to list for me!!! Greatly appreciated! I'll start checking these off and i'll post back to see what I find
