rokonworld Posted April 6, 2012 Report Posted April 6, 2012 New guy. What brought me here is I am trying to find out what's up with this 230 engine serial number. I have asked around at the HAMB and a couple other spots and no one knew, but a couple guys pointed me here to the experts. The engine is in a truck. 1942 Dodge Carryall. Originally it would have had a T214 stamped engine and I am at least a bit familiar with these engines. I know a lot of these engines have been swapped over the years and there are a few engine serial numbers I wouldn't have been surprised to find, even IND, but I have never seen one with a number like this. What was this engine originally used in? I was thinking maybe it was a military rebuild, but why would they go to the trouble to restamp the i.d. number? Any help is greatly appreciated. Thanks.

greg g Posted April 6, 2012 Report Posted April 6, 2012 military manufacture based on a mopar factory non umbered casting is my guess. Quote
Don Coatney Posted April 6, 2012 Report Posted April 6, 2012 Rebuilt by the motorpool??? I believe the "US" prefix indicates the engine was built by a (MOS 63B20) draftee. Were the prefix "RA" this would have been built by an enlistee. Quote
rokonworld Posted April 6, 2012 Author Report Posted April 6, 2012 but do you own a Rokon? Hey, someone who knows what a Rokon is! Yeah, I have a few. http://www.rokonworld.com Quote
greg g Posted April 6, 2012 Report Posted April 6, 2012 Chrysler stamped when the engines were assembled. Blocks cast in one year may not have been assembled in the year they were cast. Chrysler parts dept sold unnumbered blocks to several after market rebuilders like Jasper for instance. I would also believe they sold them by the thousands to the military for their needs as many vehicles and other equipment like welders, compressors, aircraft ground support stuff, like APC, tugs, stairs, loading conveyors, etc were powered by chrysler engines. The rebuilder was supposed to assign their own number when a block was used to remanufacture an engine. In many cases this was not doen but a tag was instead riveted onto the block indication the serial number, and what was done during the rebuild as in oversize pistons/rings, and undersized bearings etc. You might want to check out the distributor side of the block for such a tag, or evidence of rivets the held one on. There were usually in the area near the oiler filer pipe. Quote
Guest P15-D24 Posted April 6, 2012 Report Posted April 6, 2012 With that info you can figure out what is is suppose to be for displacement. Quote
austinsailor Posted April 6, 2012 Report Posted April 6, 2012 (edited) I believe the "US" prefix indicates the engine was built by a (MOS 63B20) draftee. Were the prefix "RA" this would have been built by an enlistee. Don, a 63B20 was a company level wheeled vehicle mechanic. They would replace components only, like generators, carbs and starters, as well as pack the wheel bearings. they would not replace motors or tear into them. A 63b30 would be a higher rank, with more supervisor duties, like spec 5. A 63C20 would be a similar track mechanic. I was both. Tank guy would remove motors as a unit, but that was a stage of the maintanance. They also would not be able to tear a motor down. The guys who would do that would be at the depot level, I don't know their mos code, but in reality all the guys doing this peacetime would be civilians. Part of the confusion may come from the prefix of your serial # as a soldier. A draftee started with US, as in US 55869xxx ( You don't need to know my whole #!), and a guy who enlisted started with RA. For regular Army, I think. Sometime after I got out in 1967 and went back in in 1971 they went entirely to your ssan. Edited April 6, 2012 by austinsailor Quote
Don Coatney Posted April 6, 2012 Report Posted April 6, 2012 (edited) I was a 63B20 in Vietnam 66-68. I can tell you I did a lot more than swap parts. US51874313 Edited April 6, 2012 by Don Coatney Quote
Plymouthy Adams Posted April 7, 2012 Report Posted April 7, 2012 Rokon's are very special..and very hard to come by...I have never owned one but my close friend does..took him a long time to find his.. Quote
T120 Posted April 7, 2012 Report Posted April 7, 2012 (edited) Okay Tim,Rokon's are new to me,but...always curious, I did a search and came up with this..? Edited April 7, 2012 by Ralph D25cpe Quote
Plymouthy Adams Posted April 7, 2012 Report Posted April 7, 2012 and what have you really learned from that search..Rokon's can be fun..!!!!! ??????? never but never just take anyone's word..go check it out for yourself...it can be enlightening Quote
greg g Posted April 7, 2012 Report Posted April 7, 2012 the guys across the street had a tote goat for use on the farm. Hauling salt licks out to pasture chasing the occasional wayward heifer. I remember rokons. I believe they were called trail breakers. We called the tote goat a Ball Breaker. Quote
rokonworld Posted April 7, 2012 Author Report Posted April 7, 2012 Not to drift too far, but for anyone curious about Rokons.....they are a 2 wheel drive motorcycle. The front wheel is driven just like the back wheel, with a chain. They are US made since 1962, and you can still buy a new one, they are still in production. Oh, and they float. And thanks for the great info on my odd 230 serial number. I am guessing it was a bare block used by the government. Here's the truck: Quote
greg g Posted April 7, 2012 Report Posted April 7, 2012 Nice looking lash up. Were are you located? Quote
T120 Posted April 7, 2012 Report Posted April 7, 2012 rokon,Your truck looks great - any more photos? Quote
T120 Posted April 8, 2012 Report Posted April 8, 2012 Thanks for posting the photos.I'm sure it gets a lot of attention - just begging to be driven off road Quote
Young Ed Posted April 8, 2012 Report Posted April 8, 2012 Awesome! Somehow the trailer doesn't seem quite able to keep up with the offroad capabilities of the truck. Quote
wayfarer Posted April 10, 2012 Report Posted April 10, 2012 Great truck. Any chance you drive it to the 'steam-up' in Brooks? . Quote
rokonworld Posted April 11, 2012 Author Report Posted April 11, 2012 Great truck. Any chance you drive it to the 'steam-up' in Brooks?. Heck yeah I will be there! Steam up is one of the highlights of the year. I have a 1946 Trail Beetle dozer I will be bringing. Are you dragging something out there? Trail Beetle dozer. 25 built for the US Forest Service for cutting fire lines and building hiking trails. They were built in wide and narrow guage. This one is a narrow guage, it is only 28 inches wide. Powered by a little 61 cubic inch 4 cylinder, water cooled Waukesau ICK. Quote
greg g Posted April 11, 2012 Report Posted April 11, 2012 cool little dozer, gotta be fun to play around with. Quote
Andydodge Posted April 11, 2012 Report Posted April 11, 2012 After looking at all the pics & reading the info, I've decided that RalphD25's Rokon in the one I prefer............ especially with that pale blue upholstery and red top...............is it possible to get one home delivered?...........is paypal o/k?............yeh I know.......back in the corner Andy.........lol......andyd Quote
