Title: Bumpers on 28-29 Plymouth
Post by: SD Glenn on December 06, 2010, 09:10:53 PM
Would someone tell me....  Are the bumpers on the 28-29 Plymouths Chromed? or painted with aluminum paint? or what?
Also, anyone know of a place, or site, to get connecting rod brgs for the same vehicle?
Thanks for the help

By the way, I have been following the thread about the starter button/foot pedal.. I bought my car only a few month ago, however, the gent had both systems, starter button/solinoid and the foot pedal on this car, and both systems work... which ever one you want to use. cheers.

The judging guide available off the main site here may shed some light on the bumpers. I strongly suspect chrome plating with nickel plating also possible.

The rod bearings on the 1928-32 four cylinder engines were all, so far as I know, poured babbit. So you won't just be able to buy replacements and pop them in. There are still some specialty shops that can pour and ream babbit bearings. Not sure about Plymouth but it was fairly typical "back in the day" to have a couple of shims between the rod and the cap when they poured and reamed the bearings so that the bearings could be tightened up if they became loose in service. Simply remove a shim and recheck the clearance. I don't know if that type of adjustment is recommended by modern babbit pouring shops or not.

Hmmmmm.... I can't picture having both systems. When you say foot pedal, are you talking about the type that mechanically pushes in the bendix or a foot button that completes the solenoid?

Like I said, I can't imagine how you could have both systems. One would get in the way of the other. ???

Until you made the comment that you did not understand how this could work, I took another look at the system that is in mine.  I have never seen what a "original" starter pedal system looks like, on the 29 model, but I will try to explain how this one is hooked up.

There is a button on the floor, about 4 inches to the right of the foot feed. This button I have seen on other old cars years ago, when it is depressed it completes the electrical circuit to the starter (the starter is a spin-up starter) From the battery to this button, depress the button completes the circuit to the starter. (The starter is a Delco Remy, Mod 714J, serial # 476036) and I don't know if this is original to the car or not. But it all works, thats all I care. lol
 
The other cirduit has the solenoid, press the starter button on the dash activates the soleniod completing the circuit to the starter. Neither circuit interfers with the other (unless you physically activate both and then it should just activate the starter.)  Does this make sense to you.
I sometime do not explain things right. lol. I'm sure someone will tell me this is nuts, but.....

Sounds like a typical Bendix system.

On the slightly later cars like my 1933, the starter pedal is connected to a mechanical linkage that engages the pinion gear of the starter with the flywheel ring gear then presses on a switch on the top of the starter to turn the engine over. It seems like JimCno and I were thinking of that type of system and wondering how you could make it work both ways.

Tod and JimCno,
Thank for the help.  I have seen starter systems like that and am familiar with that type, didn't know what Plymouth was using. Also, Tod, I dropped the Rod Brgs and they seem to be babbit with shims. I guess I am headed to the parts store to see if anyone sells Plasti-gage anymore, and shim stock. lol  Thanks again
