help with motor type

22 posts in this topic

we are not restorers but boss wants us to find parts for his 1954 Dodge panel truck - so glad to find site - numbers on head are DN 4.39.54 and 15544674-8 - what motor is this? so far no Pre-VIN number found but maybe when we get rust off some - is it on fame someplace ?

suggestions on where to get mostly engine parts??

Carburetor gas M25 DTG1 - who can sell us rebuild parts

thanks and sorry for being a newbie - but boss wants to get it running

The engine number should be stamped into a flat pad just above the generator, at the top edge of the block. Also, measure the length of the head. If it's 23" long it's either a 218 or 230 (assuming flat head 6). 25" long could be several different displacements. Many parts are still available through your local parts stores. I have good luck at Napa. Or you can check the Resources area above for a list of other venders that supply parts. 

Even carburetor kits can be purchased through Napa and etc. Or check online sources such as Mikes Carburators.

As Merle said the engine number can be found on a "boss" above the generator. Most factory numbers start with a letter such ad D for Dodge, P for Plymouth etc. However some engines that have been rebuilt may have altered numbers.

yes...stroke is difference in the 23 inch 218/230 look on the head, number 6 cylinder.....removable plug...a long rod will allow you to gage the travel... 218 is 4 3/8 stroke....230 is 4 5/8 stroke......rods if disassembled will be 7 15/16 for 218  and 7 13/16 for 230

Do a dry and then a wet compression test.  No sense pulling down an engine that doesn't need to be opened.  Typical problems from sitting are stuck open valves.  Compression test will show if any are stuck open.

we are leaving the block alone for now - managed to get plugs out so new head gasket and give it a try

how about parts like the thermo housing - called local used places and they just laughed - NAPA no help - anyone online that has those kind of pieces for sale??

 

thanks again - we are a lamp making company so none of us have much experience in this restoration stuff

Vintage Power Wagons is another good parts source.  Next time the Napa guys laugh at you speak to the manager about getting some one at the counter who knows  how to use their old paper parts books.  These engines were still being built for trucks and stationary power plants through the late 60's. Also for airport ground support like Clark tugs, Aux Power Units, baggage conveyors etc.  Lots of them still out there.  Also Massey Harris harvest ing equipment so check out ag. parts suppliers as well.
