nc plumber Posted September 10, 2020 Report Share Posted September 10, 2020 Are these 2 starters interchangeable ? I pulled the rusty one from a '47 Dodge coupe, has ps291 on the nose, no tag. The other from a '47 Plymouth, has ps1253 on the nose, tag MZ-4133. The rusty one turns very slow and draws a large amp load. I will rebuild it if I can figure out what it is.

Go Fleiter Posted September 11, 2020 Report Share Posted September 11, 2020 (edited) You may carefully check and compare dimensions: -hole distance and diameter, -Distance flange - top of starter -number of teeth (left one seems to have less - may work anyhow but turn flywheel slower!) of the pinion -diameter of the pinions -Pinion axle vs. flange holes -travelways of pinions (reeled out / in) If matching, make "field test" in the car. If it fits, timidly try to power the new starter... Good Luck! Go Edited September 11, 2020 by Go Fleiter Quote Link to comment Share on other sites More sharing options...

pflaming Posted September 11, 2020 Report Share Posted September 11, 2020 The dirty one is too long. I have a rebuilt starter I don’t need. Quote Link to comment Share on other sites More sharing options...
nc plumber Posted September 11, 2020 Author Report Share Posted September 11, 2020 The dirty starter is the one I removed from my Dodge. I was wanting to install the other one. Quote Link to comment Share on other sites More sharing options...

nc plumber Posted September 12, 2020 Author Report Share Posted September 12, 2020 Turns out that the starters do interchange, ?. I would still like to find out the brand and model of the rusty starter so that I can get some rebuild parts for it. Quote Link to comment Share on other sites More sharing options...
