here is a pic of the nipple off the side of the housing. looks like just a push on hose. i found a threaded hole on the side of the valve cover i am assuming thats where it goes. so can i add a new nipple at the valve cover and just push both ends of the hose on or should the valve cover end have a secured hose? thanks
-
had my oil change last week and noticed that on one side of the oil filter housing there is a small nipple on the side closest to the cab. looks like either the hose fell off or the mechanic pulled it off for the oil change and did not put i back. any ideads where this goes to. i think its a vent. its a 96 mack mech e7 350. thanks

speedo fine but no odometer?
macattack replied to macattack's topic in Electrical, Electronics and Lighting
thanks. no its not digital. only 6 plug connector and a line of dip switches. order a new speedo today. should have it in about a week. -
my 96 mr688s speedo is working fine ,but the odometer and mileage meter are not working at all. is there a seperate fuse for the odometer? any idead which fuse? the speedo cluster has a six wire connector. looks fine but will check more later. thanks

thanks guys. gonna try slicing the hose and see if a socket helps. thanks again
-
thanks guys. i will try turning, (the steel around the hose) but not too sure if it will take a wrench. the steel around the hose seems pretty round.
-
thanks for the pic,but mine looks different. here it is. and she seems damn tight too.. should i try some heat??
-
i tried again today and no luck. i was told to try some heat, but kind of scared because of its closness to the filters etc... to me its a swivel at the turbo end, but not at the oil filter housing end. i will try to get a pic.
-
got a chance to take a better look. its not a swivel at the housing end. i got some nut blaster on it to see if it helps to loosen that up. she is dam tight. anybody else turbo oil line that tight at the filter housing?? i am afraid i will pull the threads out or break something.
-
thanks. yes a mack e7, sorry for missing that. what it looks like is the swivel end is on the filter housing. and on the turbo end of the hose its a swivel. so i guess i was turning it the wrong way. duh!! thanks again
-
need to replace my oil line from my turbo to the top of the oil filter housing. does the hose have a special connection at the oil filter housing? the reason i ask is i quickly tried to take it off at the housing but damn dont know if it a special fitting or i am just weak. could not get it to move. ran out of time, but gonna try again tommorrow and see whats up. any tips?

med duty hydrolic breaks/electric over hydo park break
macattack replied to Ezrider's topic in Air Systems and Brakes
check power steering fluid. hydro boosts run off your power steering pump. with your key on and engine off you should hear a buzzing coming from your hydro boost. park break switch?? -

hey great pics and great explaination of what you did!!!! my mack mr is not set up like that, but still great info. -
took a look at my king pins today and my pass side needs adjustment. calls for .005 to .027 for upper knuckle clearence mine on the pass side is much more than that. gonna try adjusting it. the king pins were replaced a little over a year ago.
-
thanks. no issues the one reason i wish to change it is my tranny cooler was leaking for some time. i replaced that and flushed the sytem. i just thought maybe my engine oil cooler may be gummed up and should also be replaced. thanks
-
hey gang. i am about to replace the oil cooler in my 96 mr688s truck. it has the e7 300 engine non electronic. i changed my tranny cooler a few months ago and would like to replace the oil cooler also just for piece of mind and easier now with nice temps. my question is. do i need to drop the oil? any tips on replacing the cooler? also in the pic i believe the cooler is located inside the long cylinde just below the filter and above the alternator. attachment=58897:Engine pictures 006.jpg]

hi. not too sure. its on a mr688s truck and the sound seems to be coming from the center near the front close to where the power inverter connections are. took a peak noticed 3 circuit breakers and a large solenoid. the breakers seemed fine and none were tripped. gonna check the connections at the solenoid. thanks
-
sounds like a solenoid or circuit breaker clicking. seems to happen when i stop the truck and shift from gear to neutral. the truck has an auto trans. when the clicking happens it does not seem to hurt anything. everything still works and no visible signs of trouble. tha sound is coming from under the dash near the circuit breakers and solenoid. thanks
-
thanks gang. gonna double check those tie tods. i checked the tire for out of round. seems good. will recheck though. what is the best way to check the tie rods and draglink.? i should also mention i have balance beads installed. thanks again
-
hey gang. yah i have been checking this out for a while now. just when it looked like i may have won the battle it seems to return, but this gets weird. my wobble issue got to a point where it seemed to diminish, but i went a lubed up my front end king pins and now it seems my wobble is back. wtf. king pins are brand new. do you think its possible they are not installed correctly. the wobble only occurs at 35mph and is gone at 40 mph. kind of pisses me off. anyways have a great day.

probably oil cooler. check your oil level if she is going down. its the cooler
-
well out she came. actually quite easy. no crossmemeber just a skid plate to remove. 34 bolts on the bottom tank and out she came. gonna have the rad shop check it out and rebuild. what do you guys suggest using to flush the cooling sytem.
