hey guys any of you have the part number for the oil sensor that's on the top of the oil filter housing 2000 rd688s e7 400hp I called my local dealership 4 auto slack and this sensor came up to 730.00 no way slacks are 120.00 each there so there is no way this sensor is that expensive thanks guys also I did a Google search but get alot if different 1

ran it about 45 minutes to a hr I open the cap and put my finger in there at that temperature not hot at all

ok guys got everything apart took all hoses off from reservoir tank took hoses from top bottom of radiator took hose from side of motor to transmission cooler flushed everything out with water put all hoses back on filled it with cascade let it run til it was blowing hot heat inside around 150 temp on gauge now I open reservoir cap the water is still cold I can put my finger in the water not hot at all I'm thinking of changing out the thermostat what do you guys think I figured try the cheapest part first or should I just do water pump and thermostat at the same time thanks guys you'll been a great help

pic of said cooler with big orange hose and 2 hoses coming off the back

ok guys I said oil cooler it's the transmission cooler that runs off the bottom hose on the radiator my apologies I haven't had much time to really mess with it but I'm going to have to make so.e time I really appreciate you all

took belts off no bubbles took drain out of the bottom of the cooler no water comes out of there even refilled it with drain ran it still nothing comes out Jojo if your not to busy I'd like to bring it down to you have a few things I'd like to get you to do to it if possible

ok guys I have a 2000 rd688 e7 . I changed the water and antifreeze bout yr or 2 back . checked it now it's rusty so I open the drain on the oil cooler nothing comes out . so I pull the thermostat housing and the water is bubbling like crazy ..why I have no idea the truck is cold .. any help would be appreciated I have a video but can't seem to load its to large I guess

when my truck did that I just changed the shocks problem solved try to push your wheels from side to side shouldn't be able to if so your shocks are bad mines would get the truck to wobbling scary

my old truck sold it bout a yr ago has code 3/3 any help is appreciated trying help the people I sold it to out if possible e7300hp Allison auto 4560hd trans

I unplug the sensor on the top of the oil filter light hasn't been back on yet no oil in the plug plug looks great going to try a new sensor see what happens thanks guys will keep you informed

nothing in oil just changed it to be sure

no sire I've just watch gouge and its at 60psi

I just did about the Samething as you I purchased a excavator but I got my gladhand kit from anything trucks haven't Installed it yet but seem to be everything I need bunch of good videos on YouTube I just need to figure out the trailer wiring now before the gladhands

when I unplug the oil sensor on top of the filter shouldn't the shut down light come on or shut the truck off sorry 2000 rd688 e7 400 my shut down ligh. comes on randomly and shuts down sometimes not all but fires right back up I've changed water level sensor water is full oil is full I could really use some help I haul asphalt for a living and I'm afraid it might shut down not start back up thanks

ok guys my shut down light got where it comes on when I hit breaks hard at a stop or if I have to stop suddenly I changed the water level sensor still no change . what can cause this where should I look every now and then it shuts down but only when I'm stopping both tanks are full thanks guys

2000 rd688s e7 400 hp Eaton 8ll transmission truck is a great truck works everyday I have a new truck ordered and don't plan to deal with drivers anymore I've had enough rear bushing will need replacement soon truck has new floats on the front new clutch and flywheel demolition body with high lift gate I've replaced the turbo yrs ago and 1 eup everything else has been basic maintenance done I'm asking 40000 cause Bushing will need replacement there not walking but I feel a vibration or bump in the rear and a pay attention to the Rear-end

I replaced the vent a while back that could have been the problem it was leaking before I got hit but I was thinking it was the side cover

I see my bushing are about gone or gone I feel a little vibration I'm sure it's coming from the rear I was hit in the side front to back about 8 months ago and I could see where the spring had hit the saddle it was put on the freak machine and alignment machine was told in spec but I see the bushing the rear is moving back and forth not alot but it's there all tq rods was replaced bout a year ago is this a tough job or can be done at home with normal tools if possible I'd like to replace with greaseable set up

ok guys looking my truck over I see the grease is coming from the seal that's behind the big nut holding the rear yoke in the rearend is this something I can do or need to be done by shop I know on my race care it helps with the lash specs but not to sure on this

yes sir mack rears just trying not take them off miss work before I get some to swap out

2000 rd688s anybody have a good part number I'm trying to order some online but wanna be sure I get the right parts mack said they couldn't give out part numbers imagine that 😳
