Bigmackwithfries Posted July 16, 2018 Share Posted July 16, 2018 I'm looking to buy this 1956 Mack dump truck for my property. I was wondering if anyone can give me some info on the cummins engine. It's supercharged that much I know. Thanks, Dan Quote Link to comment https://www.bigmacktrucks.com/topic/53823-info-needed/ Share on other sites More sharing options...
HeavyGunner Posted July 16, 2018 Share Posted July 16, 2018 Post the info which should be on a tag on the door or stamped in the frame behind the passenger side spring hanger. Then someone could tell you everything about the truck as long as it has not been changed.

12V71 Posted July 16, 2018 Share Posted July 16, 2018 That is an old J series Cummins, With the blower it could be anywhere from 180 to 210 HP. Haven't seen one of those for many years. They were commonly called the C-180, C-190... etc. depending on the HP rating. I saw one once with a gigantic oil cooled turbo that only had a 160 HP rating.

Bigmackwithfries Posted July 17, 2018 Author Share Posted July 17, 2018 Are they 12 or 24 volt? Quote Link to comment https://www.bigmacktrucks.com/topic/53823-info-needed/#findComment-402587 Share on other sites More sharing options...

It was a screaming mother loud as hell Worked for a company that gave me a White Compact with a C-180 with a blower for a service truck, man that thing could howl. Had a 510 roadranger with a loooong stick (no linkage), on bumpy roads you had to be in a forward hole with the stick or it would jump out of gear. I remember hot and noisy was the best description of the cab.

Those, I don't even mess with anymore they get a new 12V starter, cables, and batteries. And an alternator if they had a Generator. Did an old Kenworth farm truck 4 years ago, zero problems starting to this day.

Freightrain Posted July 17, 2018 Share Posted July 17, 2018 Look under the passenger bench seat. If there is a big contactor still bolted in, then it is 24v start. Does it still have (4) 6v batteries? Sometimes you can use 12v and just wire it differently. The s/p system works well, when it is kept up. It can be a NIGHTMARE also....so if you have to do anything with it, just put a 12v starter in it and change it over. 1 Quote Larry 1959 B61 Liv'n Large......................

12V71 Posted July 18, 2018 Share Posted July 18, 2018 One thing to remember on these old engines is that there were many combinations of starters and ring gears. I have seen the fine tooth ring with a small 13 tooth pinion, coarse tooth rings with the big 11 tooth pinion, actually saw one with an old inertia drive Bendix starter (57 IH). Do your research changing out a starter for another style. I'm sure there are others here that can add to that.

Bigmackwithfries Posted July 18, 2018 Author Share Posted July 18, 2018 Welp I brought it home last night. Does anyone know where I can source a radiator? Hopefully I have time to mess with it after work today and check the tags.

Freightrain Posted July 18, 2018 Share Posted July 18, 2018 I know of two different sized radiators, not sure if that was only for diesel.? Need to see which one you have.

yarnall Posted July 19, 2018 Share Posted July 19, 2018 I have several radiators that would fit behind your shell. I'm in PA. Where are you? Quote Link to comment https://www.bigmacktrucks.com/topic/53823-info-needed/#findComment-402659 Share on other sites More sharing options...
Bigmackwithfries Posted July 19, 2018 Author Share Posted July 19, 2018 Welp looks like I need more than a radiator. I went to start it only to find out the engine is stuck. I tried turning it by hand, it turns very little one way and comes to a dead stop. Turns back a little and same thing comes to a dead stop. So I'm on the hunt for an engine. Anyone have a cummins c160 or c180? Quote Link to comment https://www.bigmacktrucks.com/topic/53823-info-needed/#findComment-402674 Share on other sites More sharing options...

Maddog13407 Posted July 21, 2018 Share Posted July 21, 2018 i dare say that truck is probably a B42 or a B62. both commonly repowered with 160 and 180 cummins motors years ago when the gas jobs let go. hard tellin if your radiator is original to either model. they were different between a B42, B62 and the original B61 diesel radiators came in a small one or the larger radiators that completely filled the horse collar was fittin to B61 turbo trucks or trucks with 711 motors Quote Link to comment https://www.bigmacktrucks.com/topic/53823-info-needed/#findComment-402773 Share on other sites More sharing options...

Bigmackwithfries Posted July 24, 2018 Author Share Posted July 24, 2018 A memeber on here suggested that something is stuck in the blower. I pulled it off today and sure enough the engine turned right over. I couldn't start it because I have the oil cooler off. I'll put it on hopefully tomorrow and give her a go.

Maddog13407 Posted July 25, 2018 Share Posted July 25, 2018 that's a B62 radiator btw. mice love old Macks. we had a b61 we bought that wouldn't turn over, turns out the mice went up the exhaust, found and open valve and built a nest on top of the piston!. turned it one way then the other, didn't have enough clearance to outdue the nest without pulling the head. they love air cleaners to, have had to clear out a few after sittin for years and glad i did before we tried to start the engine Quote Link to comment https://www.bigmacktrucks.com/topic/53823-info-needed/#findComment-402994 Share on other sites More sharing options...
