furiousgeorge Posted August 22, 2018 Report Share Posted August 22, 2018 Hello! I’m having an issue finding the proper main and rod bearings for my 251. I don’t know the year of the engine, which doesn’t help any, engine number is T 193, on the t137 page it just says 251, but not a year. The search and google didn’t help, there are numbers on the old bearings, but the local NAPA couldn’t cross them. Do all 251’s use the same bearings over all years? does anyone have the right part #’s for both main and rod bearings? Thanks! Quote Link to comment Share on other sites More sharing options...
P15-D24 Posted August 22, 2018 Report Share Posted August 22, 2018 Casting number on the block? Terril or Vintage Power Wagon should be able to help. Quote Link to comment Share on other sites More sharing options...
furiousgeorge Posted August 22, 2018 Author Report Share Posted August 22, 2018 Vintage power wagon only had a truck id, I couldn’t find an engine id section? The number stamped into the block is T193, like I said, it decodes as a 251 on t137.com, but it’s one of the very few engines on their list with no year.

Dodgeb4ya Posted August 22, 2018 Report Share Posted August 22, 2018 (edited) I think a T193 is a Fargo according to my Federal Mogul book... no other info I can come up with. Here's the T-193 Federal Mogul book showing the old mid sixties rod and bearing #'s Also shown is a set on Ebay..https://www.ebay.com/itm/Federal-Mogul-Main-Bearings-Set-485-M-30-1949-Desoto-1958-Fargo-/232698702356 Edited August 22, 2018 by Dodgeb4ya Quote Link to comment Share on other sites More sharing options...

Should have a casting number towards the rear on the distributor side. In the downloads section is a list of block/casting numbers. 1 Quote Link to comment Share on other sites More sharing options...
furiousgeorge Posted August 22, 2018 Author Report Share Posted August 22, 2018 The only number cast on that side/half of the block is a single 1. Quote Link to comment Share on other sites More sharing options...

Dodgeb4ya Posted August 22, 2018 Report Share Posted August 22, 2018 A T192 and a T194 are both 1950 H series 2 ton US Dodge trucks. But are the smaller 236 engine. Your T193 would be a 1950 engine if US made ... Canadian... might be anything. A 1948-52 long block should use all the same bearings Quote Link to comment Share on other sites More sharing options...
Dodgeb4ya Posted August 22, 2018 Report Share Posted August 22, 2018 One note... They did supply a H-Duty main set for engines with the Fluid drive coupling... same dimensions though. Here is info out of my old 60's Michigan bearing parts book... Quote Link to comment Share on other sites More sharing options...

Dodgeb4ya Posted August 22, 2018 Report Share Posted August 22, 2018 I figured it didn't have FD. Those bearings are a different heavier load type bearing and of course could be used. Quote Link to comment Share on other sites More sharing options...

furiousgeorge Posted August 23, 2018 Author Report Share Posted August 23, 2018 Well, I ended up just taking the crank in the be turned, so I gave them the old bearings and told them what I know. They seemed pretty confident that they can get the right ones for me. Quote Link to comment Share on other sites More sharing options...
furiousgeorge Posted September 20, 2018 Author Report Share Posted September 20, 2018 Ok, the crank got turned down .020. Though they're pretty convinced its from a 218 industrial based on the part numbers stamped on the bearings that were in it. Is there a way to id the crank? He wrote the casting number down for me on the receipt (955194), I'll measure the rod length in the morning. This engine has been rebuilt at least once in its life, so not a stretch to think that the crank/rods got switched out. The block has been bored .060 already, and could use it again, what is the maximum it can be taken? I've read that the small bore blocks can be bored out to the larger 3 7/16 bore, so I may end up doing that with the original 228 (it had spun a rod bearing, leading me to buying the 251), and using the 251 crank and rods (if that's what they actually are) and get a 251 with the original block.

furiousgeorge Posted September 20, 2018 Author Report Share Posted September 20, 2018 The rods are roughly 8 1/4” center to center, has 954418 on it. Quote Link to comment Share on other sites More sharing options...
