41mack Posted September 1, 2023 Share Posted September 1, 2023 Hello, new to the forum hopefully someone can help. I need a rebuild on my 1941 Mack continental 6cyl flathead. It was in storage for over 30 years. Though a mechanic about 15 years ago when it was froze up. Instead of the normal things to do to get the motor moving again he took the head off and then left the head off. Therefore cylinder walls were rusty and and number 5 was pitted. So I need a rebuild and or a replacement. I took this truck to my prom in 91 and I really want it back on the road. Any help would be appreciated.

mowerman Posted September 1, 2023 Share Posted September 1, 2023 Lots of parts available. Keep trying specially fire engine equipment section. I’m sure you could find that entire engine. Good luck and welcome aboard… bob Quote Link to comment Share on other sites More sharing options...
BOBWhite Posted September 1, 2023 Share Posted September 1, 2023 Im definitely tuned it. Thats a cool rig! Sends some pics of the engine. You might be able to bring it back if nothings cracked up too badly. 2 Quote Link to comment Share on other sites More sharing options...
BOBWhite Posted September 2, 2023 Share Posted September 2, 2023 You said it has a continental engine in it? After thinking about it some I remembered that a lot of the Massy Equipment used those engines. I've seen some in combines so you might try there. Best of luck 1 Quote Link to comment Share on other sites More sharing options...
Brocky Posted September 3, 2023 Share Posted September 3, 2023 Also Brockway used Continental Engines.. There are probably some take out to be repowered.. Check Tom Millard (Olsdpwr) on here as he repowered one a few years ago... 1 Quote Brocky Link to comment Share on other sites More sharing options...

mattb73lt Posted September 3, 2023 Share Posted September 3, 2023 The fire truck forums here should be helpful. Joining SPAAMFA could also be a good resource for obtaining parts and fire equipment. Easiest solution would be to find a good running takeout to replace it. Rebuilding can get very expensive, depending on the work involved to bring it back. Be prepared for some significant payout of resources to get it back into an operational state. 1 Quote Link to comment Share on other sites More sharing options...
mowerman Posted September 4, 2023 Share Posted September 4, 2023 I don’t know Bubba I grew up a New England and I have never heard of it but if somebody would’ve offered me the shot to drive it, I don’t know what I would’ve said, except for. I’m sure the chick won’t go for it. I had a 55 Chevy convertible at the time which was kind of out of place. Quote Link to comment Share on other sites More sharing options...
Popular Post steve s. Posted September 7, 2023 Popular Post Share Posted September 7, 2023 Ty, you have a lot of good advice already, I will offer a different approach. We don't know what your expectations for the truck are, or what kind of timeline, budget or skills you can put into this project, but.... Possibly the easiest and quickest way to get the truck to run again is to pull the pistons, hone the cylinders,install new rings, lap the valves and put the head back on. if the rust is not too bad, you can probably live with the pits in number 5. You won't ruin anything by trying this method, and you may just find out that the engine you have runs good. If it doesn't, at least you can move the truck around while you search for a rebuilder or another engine. I am assuming that the engine was not exposed to the weather with the head off. It's worth a try. Steve 3 Quote Link to comment Share on other sites More sharing options...
41mack Posted September 10, 2023 Author Share Posted September 10, 2023 Thank you to all. The truck was always in storage not in the weather. The rest of the truck is great no rust. I have time to play with and budget to get fixed. I have been looking up ED model macks and they seem to be quite rare. I will try the motor since #5 is on the downstroke I will hone as much as I can and keep pushing Kroil lubricant on it. I am thinking I am going to have to pull it though but he'll I will try. And as for the prom I had a 67 chevelle ss or the mack and the girl at that time chose the mack because it was cool and different. I am in Jim Thorpe Pa if anyone knows a good reasonable machine shop. 2 Quote Link to comment Share on other sites More sharing options...
Brocky Posted September 10, 2023 Share Posted September 10, 2023 PM / Email Steve S above.. He is in the north Scranton area and is active in ATCA.. He might know of a machine shop in north east Pennsy or know someone who does... Quote Brocky Link to comment Share on other sites More sharing options...
mowerman Posted September 10, 2023 Share Posted September 10, 2023 After reading your last post you might just have a shot. I did the same thing weather slant six years ago just kept spraying the cylinders and tapping the pistons. I freed it up after a lots of patience. Good luck bud. lots of times all it is is the rings rusted to the cylinder walls 67 Chevelle that was right there with the 55 Belair back in the day. My best friend had a 66. Again, good luck bud.

41mack Posted September 14, 2023 Author Share Posted September 14, 2023 So with tons of patience white vinegar and Kroil and hitting the pistons with a wood block and slight pressure on the crank back and forth it broke slightly. Though my bad #5 I will try to hone in place since that cylinder is all the way on the bottom stroke. I will still need a machine shop and pull the motor. I did message Steve S if he knew of a machine shop since I am about an hour away from Scranton. The guys from the Schuylkill fire museum are helping me out alot as well. Is this motor easy to pull? 1 Quote Link to comment Share on other sites More sharing options...
