air buzzer on when signals on
Joey Mack replied to Brad Carpenter's topic in Electrical, Electronics and Lighting
This is a multi buzzer, it buzzes for air, oil pressure, coolant level, and ....yes the dang turn signal... its annoying, there is a triangular bracket left of the clutch pedal, there is a wide plug that goes to it, you can unplug it...however you need to watch gauges, because now its like an old timey truck where you have to watch the gauges, because there wont be a warning buzzer, also.. if the D.O.T. man pulls you over... plug it back in...JOJO -
RD688S diag port

above the clutch pedal...under the dash -
I understand... No one wants to do this WORK anymore.. Young;ins are told they can fix them with a laptop at a starting wage of $22/hr... Forget getting greasy,, I tried going back to a Mack dealer to work up into management, I was told that my 20+ years as a Mack mechanic, and I have 5+ years O.T.R. and construction , driving late 70"s Mack RD's and DM's.... was not what they were looking for.. They need a computer person, who can talk to customers... Anyway, this kind of thinking is part of the reason why there are less new mechanics... I have also had people hang up on me when I tell them my Price.... ok, I'm done now..... Merry Christmas.. Jojo

427 ASET coolant in oil and air intake manifold
Joey Mack replied to Brad Carpenter's topic in Engine and Transmission
Have you looked inside the EGR cooler? pull the exh. pipes off of it and see if its wet with coolant... pressurize the cooling system to 20psi and look for a leak or bubbles , in the cooler... im scratching my head right now,,,,, just for kicks, pull the air compressor intake tube off and look for coolant there, mabey coming from the air compressor,,, i think the intake for the compressor is before the turbo, in the intake pipe off the air cleaner, older models got the air feed from the intake manifold, which was boosted by the turbo. good luck, Jojo -
exactly!!!!

I forgot to ask if you have mack rears,, also, was there a wear ring on the spindle and you installed 393-0173 stemco, that is why it was tight... the wear ring needs to come off, buff the spindle and if it is not damaged you can use the stemco seal, if it ha light damage, the 2 piece stemco seal kit is what you need... there are specific drivers to do the installs, can you post the stemco seal you used, I have a chart and can cross it that way....
-
check out a 370022A or 380022A seal.... see if thats the cross....

I do not have a counterbore cutter, YET... In my area there are a few shops that will come out to cut shelves if I need that service.... My rate is $60/hr. from the time i leave my house, to the time I get back.. I try to stay within 30 miles away from jobs.

Im in Salisbury, am I close to you?? I understand if you dont want to say... I just thought if you were close i could come by and help take a look.. Jojo

If the liners arent leaking, you can check the air compressor,,, It may be a longshot... Mabey another "poster" here as another idea.... Good luck, Jojo

I am a Mobile Mack mechanic, I built an E-7 mechanical 3 months ago. I used PAI parts, RE-man heads (not from Mack) and a new radiator, (also not from Mack), new water pump, PAI, air compressor, i re-used the 6 month old turbo ,per customer request,,,, $10,500.00. He called me sunday to say all is good, Pulled his rubber tire backhoe loader 70 miles to a job site... says it cranks and runs good, no issues.... anyway my point is you can re-build it at a reasonable cost... the dealers here would charge $30,000.00 if they even have someone who knows how..

The EGR cooler just has coolant flowing through it to cool exhaust gasses. Keep in mind, oil pressure is higher than coolant pressure, you have a plate type oil cooler on the left side. I have seen these fail, oil usually gets in the coolant. What I have seen many times, was liners leaking into the crankcase. Of course, I havent seen it all..... For the cost of an oil change and 2+ hours of youre time, you can do what I suggested... If theres no liner leaks, smile BIG and check other places... Jojo

Hey there, That looks like coolant mixed with the oil. If you can let the truck sit for a day or 2, loosen the oil drain plug and see if water comes out first. no need to pull the plug, just get it very loose, coolant will run out around the threads... you can also drain the oil and drop the pan, pressure test the "full" cooling system to 20psi, and watch the bottom of the liners for coolant dripping.... good luck, I hope I'm wrong... Jojo...

yes sir... i was... Next time,,, I will pay closer attention to the question.... Merry Christmas, Jojo

engine mounts are different.. the front on an e-6 is a yoke that fits around a snout on the timing cover.. the e-7 is a larger yoke that mounts behind the balancer, it sits on a hard rubber block or 2 rubber round mounts.... the rear mounts are on the tranny, and i cant remember the e-6 type... sorry... The e-7 will have ears that mount to the tranny that sit on 2 'figure 8' shaped frame mounts with rubber bushings sandwiched between them... thats all i have right now... the throttle linkage may need some tweeking... ... Jojo

just a thought,,,, yes non mack spinners can fail... i witnessed a napa filter explode once,,, i couldnt belive it... anyway, check the spinner spindle... the filter has brass bushings, however,,, these filters spin out grit,,, anyway, like I said, just a thought.. i have only replaced a few metal housings due to spindle wear, usually they are crushed from over tightening and become egg shaped. Merry Christmas.. Jojo

E7 460 Jake Brake Oil Pressure Loss?
Joey Mack replied to longshipconstruction's topic in Engine and Transmission
8 Ball/ Mack tech has a real fix..... I'm assuming you checked the core plugs on the ends of the rocker shaft also... they pop out, but also can get canted... Jojo -
E7 460 Jake Brake Oil Pressure Loss?
Joey Mack replied to longshipconstruction's topic in Engine and Transmission
Hello, Mainah,,, The .021 lash is correct... When the update was done, The Jake reset screw were replaced with an armolly pin set... 215SB321 kit... Then the lash was set to .021... they tried .017 before that.... P/S. I lived in ME. for 25 years,, graduated from Gray New Gloucster high school, in cumberland county... Merry Christmas -
E7 460 Jake Brake Oil Pressure Loss?
Joey Mack replied to longshipconstruction's topic in Engine and Transmission
sounds to me like a 690 brake that wasnt drilled for the top oil feed update.... I wonder who still has the drill jig to bore the oil gallery right... ??? i did a bunch of these about 18 years ago.. this plus a high pressure oil pump was the cure... however... mack got it right with "Powerleash" after that... as far as the check valve.. the others are correct... there was 5 pieces that had to be removed from the jake head, all replaced by the one check valve that replaced the allen headed delivery valve......Phhewwww. I just pulled that out of my.....A@#s.... correct me if im wrong... Go Bulldog!! Jojo.. Merry Christmas! -

Howdy, Diesel man..... I'm also new here,,, ,, Bring the knowledge on the Volvo/Macks... There are a lot of folks needing guidance on them...... Of course it's all about the exhaust system, starting at the turbo, or is it 'in Sweden'?// anyway, just having fun ... Welcome to the show, Jojo

"F" is right.... I have done these "in-chassis" on RD's.. DM's.... and 1 MR concrete pumper with dual steering... It's hard work.... Of course i've done plenty in CH'S and CL's... dual exhaust adds to the challenge.... anyway,,, listen to "F" from Canada... He/She has a boatload of knowledge..... Merry christmas.. Jojo
