Just put in my New LED headlights and I noticed when removing my panels that they mount a little diffrent from what I see are sold today. Mine are held in with 4 screws (one at each corner) where the panels I see for sale on Ebay have a tab that sticks out on one side that looks like it locates into a slot and then on the other side of the panel there are 2 screw holes next to the headlight for what I assume is to hold it in place. was there a update to the panels between the Mack westerns and the R models. this is new to me?

is there a 2nd part number . It looks like that was the upper filter number. I need both filters thanks in advance

always on top of it. Thank you sir

Im getting her back in shape for the road this season. Its been about 6 long years sense she left the yard for a walk. She needed new tires and a radiator. The radiator I had replaced 2 years ago but it had 15 year old tires on it so never took her out. a month ago I swap to some new/used tread off my old company truck. installed some new LED headlights as I plan on some night runs to a few shows this year. Found some that look fairly stock when off and then can light up the road great on low beam without blinding traffic. Hi Beam I can see 1/8 mile like the sun is out... You can see the comparison in LED vs Bulb. I decided that seeing at night is better than driving by candle light just to claim its more period correct. (why is the pic sideways?) The paint is shot as its spent all 15 years out side in the Chicago weather but she still can turn some heads.

Looking for the correct part numbers for the air filters that go in a Donaldson twin outlet housing . it has a upper and lower filter and I would like to replace them but I cant see a part number on the ones in the truck. Also is there a radial seal upgrade to the standard original style? The Truck Vin is a RS78632474LST its a 77 Mack with a tip turbine engine/ duel outlet housing Thank you for the help Trent Blasco

first look to see if its leaking at the roof vent or A/C unit. My 77 western had a roof mount AC unit and I ended up having to replace the whole roof sheet metal because of the rust issues it caused. if no signs of water from the roof I would suspect the rain rail has rusted out someplace and water is running down the A pillar. I have also seen water get in thru the cowl vent and fire wall with all the cables and such that run thru the wall and dont have properly sized grommets. Driver side kick vent is also suspect as it had s rubber seal when the vent is closed

it says 13'.4" but I see some of the more brave, or experienced sneak under it. the scuff marks tell the truth of your hight LOL

what were her spec's? it was a good looking Dog

WELCOM BACK DAN... I look forward seeing the new build... sorry to hear about how Mack treats one of their Iconic trucks. some times people are just that ignorant. I hope someone higher up at Mack sees this. if anything just to make them think a little harder in a attempt to save the brand..

4014 came thru town last month. Took the wife and kids to go is chug thru town. it only had about 10 cars in tow and it was not hammering the ground like I had thought it would. In fact is sounded more like a air pump as it went past as it was not under heavy throttle with such a short train. Im sure when they put some weight behind it she will come to life and put on a good show. The the next day a friend and I went to where they parked it for the weekend. its most impressive when you can view it without people standing in the way. you can see the craftsmanship that was put into getting her rebuilt. amazing to think I was able to see "the worlds largest" steam locomotive in operation.

I think they are gone. they had a few trucks running around hauling scrap in to general last year but have not seen them doing any work around town in a few years. their yard was sold to Lorig recently

sorry but that looks Dismal to drive and even worse to live in.....

Who the hell is this guy with this ridiculous first post LOL???? coming to a mack truck forum to bitch about us "Mack guys" enjoying a pic of a mack locomotive pic you supposedly took ? A pic that was posted to the World wide web for all to see and share? . Not the brightest crayon in the box are ya? Just for that rant I'm going to share it to Facebook and if I'm bored I might hit up Instagram too ..... Let me know how the legal proceedings go so I can adjust my schedule...I have been real busy lately stealing online pictures ya know...make a killing selling them but that's another story. 10-4

Pure example of a big company trying to force the little guys out and throw a wrench into their larger competitors

https://www.shapeways.com/shops/ssmcollection?section=MACK+R+(1%3A16)&s=0 I have built 3 Mack R models with this guys stuff from shapeways.

if it has the period correct luberfinder it likely has to fill up that whole filter assembly before you start to see any oil pressure. thats how it was on my END711. you might be able to pull the turbo oil feed hose and pressure the block with oil first if you want to play it safe? I think there are some aux ports on the side of the block as well where you could force oil into it?

correct me if Im wrong but the disc brake pad does not have as much working surface area as drum brake shoes do. ? if that is true that can be why they wear out faster.

saw this one in Dolton IL yesterday. Is this a HME?

did you check the water pump to see if its pushing water? if its moving water and the belts are tight next. pressure test the system to see if you have a bad head gasket pushing air into the coolant? you would see soot and bubbles in the coolant. the weep hole is to allow air to bleed out of the system. it also helps keep the t-stat housing always full of water so that the t-stat will open and close at the correct temps. some t-stats have a small hole drilled in the ring. others may have a check ball. the reality is I have never noticed a car overheat because of the weep hole location. once the T-stat opens it lets out any air and the turbulent water should carry any air out of the housing.

This was my Dads 76' R model with a fancy paint job pic was taken in 1980

Well Cat is out of the class 8 market. so the reality is that Cummings is the next mfg that offers a big bore big HP engine. Mack and cummins have had a good history between each other thru the years and I see no reason why the option is not offered for big HP in a Mack. the thought that a company (volvo) is removing the whole big HP option is just a shot in their own foot. I still cant wrap my head around their thought process on this

“We actually outpulled a 600-hp Cummins with a 505-hp Mack,” I think he meant we out geared the truck with a 600 cummins. A 600 cummins has 2050ftlbs of TQ where a Mack 505 only has 1860ft lbs. them automatics are fast but I dont see a 505 mack out pulling a 600 cummins on a long steady grade. I will believe it when I see it....

another missed opportunity for Mack to be part of... Looks like Dan is doing just fine. good to hear.

4.64 rears with 43.4" tall tires with a .78 overdrive in 12 gear at 2100 RPM you will be at 74.95 MPH 1800RPM = 65mph https://spicerparts.com/calculators/transmission-ratio-rpm-calculator

I wonder if the Allison is better than the Mdrive as far as performance and reliability?
