Like skydawg stated a surface grinder would probably work better I hadn’t thought of that

sorry i thought your first post was a B model mack,,bob

truck is gorgeous,,,i think i mentioed i hadda 67 IH scout,,with the same door handles

Or a surface grinder if it`s too thick,doesn`t sound like the OD needs to be turned down.

Thank you to all who responded . Robert

Believe it or not we had quite a few Mack’s running around LA. I could think of about eight companies that had them off hand. OK now I’m stepping on Barry’s thread.

Well, I think I had a 500 horse V8 in it. I think it was sometime somewhere around 87. Bob

I don’t think I’ve ever seen one without spoke wheels lol

That thing is immaculate wow… and 10-4 on the simple times … they used to be everywhere.. pops company had a buncha box trucks with those beacon fast freight… have a ball with it and thanks for the cool photo

Larry I remember back in the dark ages when I first started at the place that ran all R's and F models and one or two had the three filters. My 260 hp was made in 1980 and it had a cartridge filter I swapped it out for the filter setup off a 285 hp and a little bigger pan off another engine that was setting in the junk yard the junkers put a big hole in the oil pan when they pulled the engine that 300 should do you very well I drove an R with a 285 hp that I in chassis over hauled and it did pretty good in that triaxle dump

This engine has ESI so bigger pan and three oil filters. The deep pan won't clear my front axle. It is 7" deeper sump.

I realize that it would be a little bit to the extreme but if the one listed above is to thick would it be possible to tack weld it to a piece of round stock and chuck it into a lathe and turn it down and then remove the round stock and dress the welded area as needed

Thanks for the followup. I just bought a 1992 Mack RD688s and I am working on the interior lights.

Try reaching out to this group: https://harvesterhomecoming.com/contact-us for information on your truck. Fort Wayne was once called the truck capital of the world due to International Harvester. They have a big show each summer and there is a lot of info available from this group of former employees and collectors.

No I haven't I get a eup 4 code every now and then when its cold but goes away at operating temp but a month or so ago the engine was hanging in the rpms to the point it was hard to shift but was intermittent I sprayed some lube on the bottom of the pedal and it went away but it has always had the dead pedal issue it dont completely go away when it happens but its like you are holding at half throttle and some times it last longer than others some tims its back to back some days it may only happen once or twice

Do you have a photo of that White. I believe George Tackaberry has a Gerosa White flatbed.

Thanks PMC, talked to Kevin he might be able to help us, and was great to talk to, truck is just about gone , but we are going up to hang out and talk......Jack

I think you can... Besides,,, if you put the hub back on with new bearings and seal and do clean work, you wont ever need to do it again. Hell, trace it out on a peice of cereal box cardboard to make a template, and make one from some thin steel later on. You wont 'f' it up, and you will have an extra. Just sayin'....

I'm going to see how much I can salvage. I think there is enough to make it work.

Well its taken me along time to give an update. But here we go .Sorry for the wait 😀 I did lots of polishing , some painting and some fixing . Can you believe that it needed a lower rad hose and the International dealer could still look up the part number and FIND it . I couldn't believe it . I've had it to some shows and was able to find one of the previous owners . He had it in the 90's and had a fertilizer tender on it . Thats why it had a hydraulic tank and pump. I still don't know who bought it originally . So its still a mystery why it was spec'd the way it was . The trans works good and the transmission retarder works amazing. Thanks again to everyone that helped me figure it out . Other than keep history alive it doesn't really have a purpose. But I love starting it up and cruising around a bit in it . Takes me back to a very simple time.

Are you getting a throttle pedal code ? I think its 6-5. And yes, the TPS on the pedal can be the issue.

now why wouldn't it be impressive !!!!:: IT'S A MACK. LOL

Well, you and Mech responded.. 🍻
