Buttiman53 Posted February 20, 2017 Report Share Posted February 20, 2017 I noticed today, while troubleshooting my generator bearing issues, that the crankshaft on my '53 B3B has a noticeable wobble, mostly at idle. I took the fan belt off and tried to moved the pulley but it seemed snug. Wanted to know if this is "normal" for a 64-year old truck, and if anybody else has ever noticed the same thing. Hope it's not an indication of things (bad) to come. Quote Link to comment Share on other sites More sharing options...
Reg Evans Posted February 20, 2017 Report Share Posted February 20, 2017 The pulley on the 50 Chrysler 251 installed in my 52 1/2 ton has been wobbling since I installed it in 1997. I'm not going to fix it until it breaks. Quote Link to comment Share on other sites More sharing options...
wallytoo Posted February 20, 2017 Report Share Posted February 20, 2017 same pulley wobble on the 237 in my 1.5-ton since purchase in 2007. Quote Link to comment Share on other sites More sharing options...
The Oil Soup Posted February 20, 2017 Report Share Posted February 20, 2017 Mine wobbles slightly, seems to work fine. '53 should be a B4B. Quote Link to comment Share on other sites More sharing options...
Buttiman53 Posted February 20, 2017 Author Report Share Posted February 20, 2017 Thanks for the info. It's a late B3B made in San Leandro in 1953. Quote Link to comment Share on other sites More sharing options...
DJ194950 Posted February 20, 2017 Report Share Posted February 20, 2017 Have you made sure the big nut that holds the pulley/balancer on "if it has a balancer" is tight?? Some balancers were made in two pieces with rubber molded between the two parts that often gets bad with age and can come apart. The worse that can happen? - a part comes off and destroys the radiator. You can try with a mirror and light take a look at least. Actually hope that it not your issue and someone got crazy with a hammer or other tool at some point and it's just bent! Livable for now.

Mine's an early B4B made in San Leandro in late '52. What rear fenders are on the truck? Quote Link to comment Share on other sites More sharing options...
Fernando Mendes Posted February 25, 2017 Report Share Posted February 25, 2017 My canadian truck B3-B(serial number 90099559) wobbles its crankshaft pulley too. Quote Link to comment Share on other sites More sharing options...
lonejacklarry Posted February 25, 2017 Report Share Posted February 25, 2017 As quickly as I get mine running, I'll let you know. Quote Link to comment Share on other sites More sharing options...
Buttiman53 Posted February 25, 2017 Author Report Share Posted February 25, 2017 (edited) I know this is getting "off-post," but..... My B3B-108's serial number is 85320376. The "Model Chart and Serial Number Guide" found on the DPETCA website lists 85313701 as the first number for 1952, and no ending serial number for that year. The "Deciphering your 1948-53 Dodge truck code" guidance also found on the DPETCA website lists serial numbers starting at 85313701 as 1952-53 model year B3Bs made in San Leandro, and 85322001 as the starting serial numbers for B3Bs built in 1953. This overlap has always confused me. The registration for my truck states 1953 as the year, so I always figured it was either built later in the production run, or shipped in 1953. It has the round rear fenders. Edited February 25, 2017 by Buttiman53 Quote Link to comment Share on other sites More sharing options...
