0 JoeH Posted July 27, 2019 Share Posted July 27, 2019 I think flywheel housings and bellhousings tend to be fairly standardized. I.e. if you can put an 8ll on a Mack and a Cat, there's probably a bellhousing/flywheel housing combination that'll match a Mack 10 speed to the Cat.

0 1965 Posted July 27, 2019 Share Posted July 27, 2019 Back in the 90’s. Worked at a DD dealership. We worked on a bunch of Roadway stuff. Always thought the 3208 was kinda like the 8.2 DD’s. We did a bunch of R&R on the 3208’s for them. They were better than 8.2 for sure but always told they were throw away engines. Run till they quit & replace. Really don’t know but that’s what I was told. Quote Link to comment Share on other sites More sharing options...
0 theakerstwo Posted July 28, 2019 Share Posted July 28, 2019 A 3208 is fully rebuildable.i have did a few back when.We always bored the block and installed dry sleeves and used standard pistons.The 1100 series was not rebuildable. 1 Quote glenn akers Link to comment Share on other sites More sharing options...

Long time ago; don’t remember but I bet it was costly to bore & install sleeves. I could see on 1,cylinder but all 8? Quote Link to comment Share on other sites More sharing options...
0 theakerstwo Posted July 28, 2019 Share Posted July 28, 2019 Most people did that because the sleeve was better for wear than the cast block.You could get a over size piston but some thought the block would be thin after boring it. 2 Quote glenn akers Link to comment Share on other sites More sharing options...

0 davehummell Posted January 9, 2020 Share Posted January 9, 2020 If you ever been next to a 1160 starting up when it was cold god help you we would start them up in the shop and it would stink us out. The 3208 was a better engine design but they were put in trucks that they should never have been in. We used them in ford flat bed single axle 33,000 gross they worked good. If an engine needed 8 sleeves we figured it was better to get a block exchange. Cat had some pretty good deals years ago on reman's. You could get a reman 3406 head and 9 times out of 10 it was new for not a lot of difference money wise when doing a valve job with new valves. 2 Quote Link to comment Share on other sites More sharing options...

My MACK production papers only list model call outs, years of production and number built. Probably not one specific company as the 135 built were spread out over from 1975 to 1981. There was also a run 40 R492R models built from 1976 to 1980.

The trucks were built as 5,000 gal. refueling tankers with the 3208 and automatic transmission. The DM-492 were built between 1975-84 with 1,536 units produced. I would say that almost all the DM-492 trucks probably went to this application. 1 Quote JimIt doesn't cost anything to pay attention. Link to comment Share on other sites More sharing options...

0 Makeri_Driver Posted March 31, 2022 Share Posted March 31, 2022 From my use the 3208 is the worst Cat engine ever made and probably one of the worst diesel engines ever made! I hated them in Louisville Fords! They had no power and my 534 Gas would out pull it. The only way I would be willing to work on a 3208 would be to remove it. I would rather run a 671 Detroit in its place! At least it would sound good! Quote Link to comment Share on other sites More sharing options...
0 Popular Post theakerstwo Posted March 31, 2022 Popular Post Share Posted March 31, 2022 (edited) I went to a cat school in Peoria in 68 for that engine and another engine but the 3208 was a 1100 series then and a throw away engine.The instructor told us then the ford wanted a cheap compact engine that would burn diesel fuel and cat gave them one.I fould in the years later the 3208 was in most cases under specs for its size.I have worked on many of them and found little problems with them.We would time them about 2 degrees fast and that help some for cold diesel smoke and i found when we overhauled them to send the block to the machine shop have them bored and sleeved back to standard and the sleeve i believe was better iron than the block. I still have my tools for them.The turbo engine had a little more power.Alot of dump trucks here used them.I was working for freightliner then and we was doing cat warranty work on them for Ford dealer here and i got some of them.O i would much more be happier working on a DD or cummins.

0 67RModel Posted March 31, 2022 Share Posted March 31, 2022 Years ago at one of my first laboring jobs as a teenager we had one in a 1988 GMC Top Kick dump truck. 33,000 GVW with a 2 speed rear end. I couldn't drive it because it was a CDL truck but everyone who did abused the ever loving snot out of that truck/engine. Always overloaded. Under maintained and just down right abused. Some of the guys did it intentionally because the rest of the truck was just utter GM junk and they didn't like driving it. That thing never missed a beat. That engine would start and run no matter what. The company ended up selling it years later to a farmer who just wanted it for his property. The frame got bad rust jacking and nobody would pass the state inspection on it. Ran like a sewing machine when the guy took it away. That's my only experience with a 3208 but have always heard they were underpowered for their size (10.0L) and not "good" engines. 1 Quote Link to comment Share on other sites More sharing options...
0 mowerman Posted March 31, 2022 Share Posted March 31, 2022 I never really heard any bad stories about any of the other sizes except they were very expensive to rebuild most of the guys I talk to really liked them but I did hear their fuel mileage was lousy…..

0 mechohaulic Posted April 1, 2022 Share Posted April 1, 2022 every engine in the day had a Nickname; DD =carry 10 gallons of oil were ever you go. cummins = a boat anchor. cat == take out a mortgage if you want one. the 1160 was called a throw away; replaced by the 3208. i did a swap for a customer had a ford dump single axle. saved the best for last ;;;;Mack = now there's an engine .. before the days of electronic intervention on engines . $$ were important for owners ; it worked use it Quote Link to comment Share on other sites More sharing options...
0 doubleclutchinweasel Posted April 1, 2022 Share Posted April 1, 2022 Only Cats I remember in a truck were a 3406 and a 3408 that we had. They seemed to hold up okay. The 3408 pulled great, but the mileage was lousy. We always laughed that it seemed to use as much fuel empty as it did loaded. So, always keep it loaded! Rebuilds on them were ridiculous, though. Now the D342 in the D8 and the 3306 in the D6 and some D7s were pretty tough. But, that's a different forum... 1 Quote "Eagles may soar, but weasels don't get sucked into jet engines."

0 mechohaulic Posted April 1, 2022 Share Posted April 1, 2022 can't compare the 3406/ 3408 with the 1100/3208. cat 34 series were real truck engines. the 11/32's were cheap engines (favored by some fleets)used to make a truck move. a LITTLE difference in fuel cost then vs now 1 Quote Link to comment Share on other sites More sharing options...

0 mowerman Posted April 1, 2022 Share Posted April 1, 2022 I drove at 4:35 for a short while that thing was amazing again I got knocked out of it by somebody with sonority. but it was great while it lasted drove it a couple of months..
