I always use a gallon of Lucas...some people hate it ,some people love it.. usually no in between..lol.

it's on an isx...but same principle applies.

I second that... I think low threshold oil psi for that year is 15psi....so your good there . besides for the amount of run time you've given it in 6 years , that amount of blowby is no concern...but if you do plan to run it constant, wouldn't hurt to get a manometer test done to see how bad your engine wear is..clear hose with a u shape and some water in it connected to a crankcase pressure source with a pressure relief.. there's a good video on YouTube about this...I'll try to find it.

When I swapped my t2090 to eaton, I got an aluminum bell housing..over time the steel rivets cast in the aluminum busted off because of torque I believe.being a dump truck and off-road all the time didn't help it none.Long story short ,it broke off the passenger side transmission mount and whole engine leaned to the side..it broke the econovance fitting and engine ran itself mostly out of oil until the low oil pressure shut her down...I guess what I'm trying to say is when converting to eaton , look for the steel bell housing..

First let me start out by saying that if you're coming from a cat or a Cummins, a 12 liter Mack engine will feel like a mut. Someone correct me if I'm wrong but I don't think the XT program was offered an RD chassis.the s400 is stock yet there could be reasons why truck would be lagging. Dirty fuel filters, low fuel pressure to the injector unit pumps or could have fault codes hindering power.

o ring in side cover 2000 rd688 rearend
R.E.D replied to Moparmike's topic in Driveline and Suspension
Yea I figured.. cutting corners..I bet they figured the aluminum last too long , therefore they made plastic which becomes brittle and brakes while removing.then they charge an arm and leg at the stealership for another plastic one.lol.only way they get us to stop rebuilding and repairing our older equipment is to make replacement parts with lower quality and prices higher than giraffe 🦒 p***y... excuse my French.

o ring in side cover 2000 rd688 rearend
R.E.D replied to Moparmike's topic in Driveline and Suspension
Yea it's some kind of plastic..has brass spacers molded at the four bolt holes as to not crush the cover by over torquing them...the fill hole plug is rubber and snaps in like the plug on a front axle wheel hub..they get brittle and brake while removing...I changed mine to aluminum about ten days ago wheel I had my rear end rebuilt. -

Can't help with part number, but there are two kinds of covers plastic and aluminum.. plastic cover oring is thicker than aluminum.which one do you have? -
Do Mack Trucks Comes With Cummins From Factory?
R.E.D replied to Kunle's topic in Engine and Transmission
CL had longer hood as well to accommodate these bigger engines. CL733 Cummins engine CL753 Cat 😸 engine CL743 Detroit engines...but these are rarer than a honest politician. Also .. different frame Red -
E7 350 has warm egt’s with 4” turbo back exhaust
R.E.D replied to rhinoo's topic in Engine and Transmission
Absolutely, 5" will flow more cfm, therefore lower back pressure and lower egt's.But I don't think the drop in egt would be substantial.If your not running a straight pipe, check your muffler for obstructions ,it could be plugged up from years of use...but never the less in my opinion, it's never a good idea to give a driver a modified truck..that's just asking for trouble...just my .02¢ -
Yea ..the deer 🦌 in the headlights look is all too common in my area.. specially in the mack motors , I think macktechnician used to call it gray engine amnesia ... around here, taking your truck to the dealership is as useless as tits on a boar hog.lol

Trying to figure out an EUP without software
R.E.D replied to zeault's topic in Engine and Transmission
Yes , etechs are clackier than the later ami / ac motors..I had the same nagging clack not long ago, used a mechanic's stethoscope made my Lyle to zero in on the damage eups, 3 had loose springs.i took them all off and had them tested....ended up replacing 2.

Absolutely, everyone had been preparing for a while..the county I live in ( montgomery) is big supporter of Mr.trump.
-
I was told as well that they stock mack parts , specially for common gear ratios like 4.17 and 4.42.i have 4.42 so I was in luck...

Back one...I did the front one end of June 2021... Thursday I finished my day at around 5pm.yesterday morning took it off and had it rebuilt by 430pm...put it on today.. Houston has a truck hub, off mcarty street.. endless Miles of anything semi truck related.. including 4 or 5 gear train rebuilders..they work fast ...work has warranty as well so they work with diligence in order not to have warranty returns.

I pump untill new grease shows , except scams, because as mechaulic suggested they fill , the brake shoe with grease and could create unwanted problems.
-
Yes sir, that's why I favor them ,the stop and go abuse wears them out.

Thank you sir..Euclid is what I bought in the past. Just couldn't remember.

My s cam bushings are shot..I plan on doing an rear end complete overhaul pretty soon..I go to the mack dealer for an unrelated part and ask for a quote for all the brake components for the two drive axles.i ask for the metal s cam bushings not the plastic..guy at the counter says he has never heard of metal s cam bushings..and he has been working for mack for 14years...I didn't want to sit there and argue with the guy so I played dumb and got my part and left...but I remember I installed brass or bronze s cam bushings on my Rd before .does anyone have the part number for the bronze bushings?crd92 93 I believe.. thanks Red

2000 rd688 e7 Eaton fuller 8 speed help
R.E.D replied to Moparmike's topic in Engine and Transmission
When you replaced clutch, did you take the flywheel to get resurfaced?if so , did you make sure you got your flywheel back and not someone else's? Also I could have sworn there was some post here or service bulletins about the depth of those sensors , and shims.. someone correct me if I'm wrong. -
#1 and #6 are on the same Tdc stroke,just something to note
-
I'm not to educated on mp engines but if they are like any other diesel engine, I would assume that a cylinder balance or contribution test with failed compression will cause the engine to speed up where the compression stroke happens in the dead cylinder , it's an audible speed change when cranking.did you test compression with a known good analog gauge or just electronically?
