Here's some more on starters...Scroll down to read all emails between me and John Grady. Hope that helps or at least brings more info ... 300'ly Jean-Yves ----- Original Message ----- From: Jean-Yves Chouinard To: John Grady Sent: Thursday, April 01, 2010 12:08 PM Subject: Re: [Chrysler300] Battery/Starter-300F Yes stock F and G starters do not have solenoid on top. They do not fit 62 up 727 trans. And the 727 starters do not fit the pre 62 cast iron trans. No interchange possible there. Physically will not fit. I never had a 318 cast iron car so i can't tell you if that starter is interchangeable with the big block cars. If they do, maybe that is why there is two part #'s in the Chrysler book and maybe that is the reason for the "regular" winding and the "heavy duty" winding. I could be wrong here , but if I remember right, on my first 60 Polara( cast iron trans.), the starter gears are in contact with the flywheel or torque converter gears, and the starter gears "backs up" inside starter and out of the way as the car starts. On 62 up 727, the gears on the starter drive are pushed out of starter to meet gears on torque converter and then back inside as you release the ignition key back to normal. I say that because I remember I had to bring the starter back to the rebuilder on my 60 Polara because the "tension in a spring inside" had to be adjusted. Not enough tension on that spring made the starter release out before the car was started. The engine would just spark but not quite start and the starter would disengage even if I kept the ignition key on!! That is how they work, spped of the started engine disengages the starter drive... So that is the difference between the pre 62 and post 62 starters...they operate differently. Does that make any sense? I was going to ask you if I should post your responses on the list server...I will...

Maybe I am mixing stuff up myself, and there are in fact two different Bendix drive starters ?? It someone put in a 318 starter, and it fits cast iron trans, it definitely would not crank 413..or 392. The 318 starter would have been far more common in auto parts stores of the day, if it fits and looks alike, may explain some of this??-- someone put in a wrong, commonly available starter at some point in past 50 years, in some C300 to G's? . There is a lot of confusion around this . My point on F is the correct stock starter works fine, rewinding it with heavier wire is not needed, but maybe there is more to this? Yes, the later "ministarter " has a gear reduction, it is smaller because later permanent magnet needs no winding, but it spins faster, so more gear down is needed. I think that was an "across the board" upgrade at some point by MOPAR in 70's or 80's? You can tell easily by looking if a gear down design, the motor axle is not in line with the drive pinion, as the gears offset it? I remember when it came out, it made a strange loud noise, but cannot remember what year . They must interchange with 62 up older solenoid on starter style, as 727 did not change , and current MOPAR performance mini fits all aluminum case trans ( I think) ? It makes sense that the starter was upgraded or changed with 62 aluminum 727; that says 62 up big one with solenoid may be totally different in overall starter design. Maybe that is what Bob is talking about? Do we know it if fits the earlier cast iron mount pattern, independent of one wire or two(that change is easy) ; big difference would then be solenoid on top or not? Did pre 62 Chrysler ever have a solenoid on top? I though HD did have it, but that is usually two wires (it can be one) .. Maybe pass this on too; this discussion helps all of us. I did not want to , or mean to add to confusion on design changes; I only know for sure that 318 Bendix drive starter, no solenoid on top, on stick shift flywheel will not crank the big engines, but stock correct 300F starter is OK. Pass on, lets see what others know about interchange aspect..?

Probably 55-59 too...But 1962 saw the appearance of the aluminum case torqueflite (727), and the starter for those is different than the previous years. No interchange here. I don't know if you call it "gear reduction" but I know Chrysler kept that basic starter design for years after that. Then you go to like the 80's and 90's on Dakota trucks(with V6!) and cars too like the 80's 5th avenue 318 cars... they have what I call a mini starter. That starter will fit on a 1962 Torqueflite!! And will crank that engine up real fast!! That is probably what you call a "geared starter"??

One has a Bendix type drive, the light duty one, and an input stud only, without a solenoid on top. That was used on lighter engines than hemi and 413, I am not sure of how it was broken down. I think the light one was on 57 D500 325 hemi's . It will not crank a large 392 engine against normal spark advance, I DO know that; I had it on a 392 300D engine, with a Plymouth 301 or Dodge 325 hemi flywheel in a 57 Dodge D500 convert, 3:70 rear, Packard OD trans, all this about 1961-2. (Ate 57 chev 283 FI daily for lunch! Got a new 62 or so 421 Pontiac Ventura 4 spd coupe too! Top end pull away ! ) Starter came from a 325/318,/301; A Chrysler sourced aluminum adapter plate was needed then to hold the starter, space back clutch bellhousing, about 1" thick, that may have come from Plymouth or Dodge too, or possibly an early hemi , forcing the small starter w stick. I used a dodge 11" oil truck clutch, B&B type, I think 3200 lbs of springs! I knew no better, thought a starter is a starter (I was 18 or 19!) ; 392 from a junked wreck had no starter with it (That Packard stick OD w 392 D ,would be a hot setup today!). Paid 250$ for 300D engine in late 61... I should have gotten the starter for that huge amount! I tried to find out more at the time about stick shift 392 in late 50's big Dodge trucks, but rare piece. Only 392 factory stick? I had to drill into crank for pilot bearing clearance , shorten trans input shaft etc. Started with late 50's MOPAR stick trans, blew about 12 of them; could not take it, crummy pin syncros snap off, drop down, blow countershaft gears. Packard was a huge upgrade, gears are huge, as are cone type syncros , 2-3 only. That ~ 4" stroke of 392 is not kind to stick transmissions.. One good idea I came up with was a machined ring pressed into TF 392 crank end pocket to actually hold a shortened pilot bearing on perfect center ; hole behind was clearance only.. I have no idea what a rebuilder is selling "for hardly any extra $" but the stock F 413 starter started the cars,--- if the battery and starter are good and unmolested. The original starter typical problems are probably worn brushes, worn bearings, stuck brushes, burned commutator(all somewhat normal wear) ; contact burn/failure in solenoid ; winding shorts / faults would typically come from thermal overheating, why they tell you to crank 30 sec max and then rest, stuff like that. Or stuff like wet/splash/flooding, poor storage etc. Also, these failures are why the original that did not work was fixed by any suitable rebuilt or NOS replacement. As I mentioned, you have a 5 pound bag, in terms of winding space, you cannot put a 10 pound winding in it. Maybe a later, larger OD field frame exists? Heavier wire will of necessity have fewer turns in same space, draw more current, may make it better or worse. With a diesel size battery, maybe better. Certainly better than an obviously known to be defective stock one. But we know absolutely the stock one worked fine in 1960. I have had a lot of D's and F's, never had starter problems, maybe just lucky. I do not remember when gear starter came in on 440 `B block..do they fit? Was this F one still in J?? that is one tough cranking job; I sold my J long ago, but remember rapid cranking..

I would just like to make a few comments though, if I may. If there was only one (non-gear reduction) starter available, why did my rebuilder tell me I had a light duty winding in my starter, and then offer to obtain and subsequently install the heavy duty version in my starter? Why did the problem go away once the newly rebuilt starter was installed? I changed nothing else but the starter. Why does the 1961 parts book show two starters? Shown is a p/n 1889100 for the 318, and the 1889200 for the larger engines. For troubleshooting purposes, the AEA Tune-up spec sheet shows the Chrysler starter, p/n 1889200 Free Running Speed current draw @ 78 amps max 11.0 volts; Lock Torque (stalled) current draw @ 350 max amps, 4.0 volts. This information may help with diagnosing the problem. 300ly, Bob J From: Chrysler300@xxxxxxxxxxxxxxx [mailto:Chrysler300@xxxxxxxxxxxxxxx] On Behalf Of Jean-Yves Chouinard Sent: Tuesday, March 30, 2010 8:52 AM To: Chrysler300@xxxxxxxxxxxxxxx Subject: Fw: [Chrysler300] Battery/Starter-300F Hi to everyone.

As an EE ,and PE, I have a perspective on it. Maybe you can pass this on... First the starter as designed started thousands if not millions of B blocks and hemi's over the years , (at 10 below zero, too! ) and does not need redesign or new windings of heavier wire. Heavier wire draws more current, which drops the battery volts even more, and needs the same # of turns to get the same magnetism, which is what makes the force. The force is proportional to turns, as well as to current. As more turns of larger wire will not fit in the same space , it is the wrong way to go and may make it worse. The resistance of the wire does not change or deteriorate over time; it does increase a little when hot, but that is normal and was accounted for when the unit was designed. Anecdotal talk of how heavier wire improved things has more to do with just rebuilding the starter , new brushes etc. Heavier wire means an 8 volt starter is now used on 12v; pros and cons to that. Works great , fast spin on a nice warm day... may not turn at all when cold. You can separate this into two problems1) the engine is hard to turn 2) the starter is not providing full force . It is critical to CLEARLY find out which it is (!) before doing anything, or you waste money and time. Hard to turn, but starter OK, is usually timing too advanced (distributor weights did not return, or wrongly timed, or "turned up' timing in pursuit of performance-this has a characteristic cranking sound, quick turn followed by almost stall at TDC, repeat .) , a mechanical bind in starter drive (tolerance of starter pinion to ring gear-it must not jam-loosen starter and move back etc; damaged or off center ring gear.) or something in the engine, transmission or belt drive is dragging(unlikely, if car idles and runs OK). A too tight piston or ring fit in a rebuilt engine can REALLY aggravate things when hot... If starter is good, and you measure starter current draw, it will go way up when hot if engine bind is loading it down. Current draw on a good starter is always proportional to how hard it is to turn, if starter and battery are OK. . So, you really need to know that number; you must have a starter ammeter to say anything about what is wrong. Second problem, not enough force from starter, is actually easy to troubleshoot. The service manual provides a starter no load speed and 'locked rotor " torque value...do what it says, to find out the story! --and sometimes gives an ampere draw at locked rotor and free spin. You do need a starter ammeter; !!! check the draw IN the car is job # 1 !!!, while cranking hot and cold and measure battery volts at the same time. The battery should stay at 10.5-11 or more , no matter what you do; if not, battery is in question..most common problem, or a cheap toy battery. Winter storage allowing it to die and then a spring charge cuts 50% out of a battery; a carbon load pile can find that.(Harbor tool) . Always buy batteries by weight, not sales bullshit; the bigger / heavier the better; store inside on wood surface (no concrete) and trickle charge once a month for a 24 hour day. Leaving trickle charger on , even fancy 'self turn off" ones, can wreck battery by evaporating the water. . Cables must be heavy gauge, in good shape and tight. Cheap thin cables loose power, but any problems in cables or ends will be accompanied by getting hot when trying to start for extended times. Feel the ends for heat after cranking for a minute or so. It is not generally necessary to scrape paint etc, as bolt has no paint and current goes through that side into block too. ..but it cannot hurt. The free spin test in service manual checks for shorts in armature, as it will not rev up to high speed with a shorted armature; you also can check resistance from commutator bars to shaft, should be an open circuit...most shorts are from winding to shaft or core, but turn to turn shorts happen too...and slow down rev test. Test field winding for shorts to frame too. There is a free spin rated current, it should be within 5-10%.The locked rotor test is a little tricky to do, but checks torque output vs. current draw; it draws very high current for that, which will find bad brushes or open windings in armature. Worn brushes imply a lower spring pressure, and I have seen brushes 'frozen" to the brush holders by long storage and so not pressing on the commutator; that leads to low torque and bad burning which destroys the commutator. Always free up brushes in slides, check them when rebuilding a stored car( generator, too) . Problems with armature can usually be found visually..a shorted turn will be burned, or commutator burned etc. = look carefully. In the realm of weird things, I had a situation like this, it turned out to be the wire lead attachment / big bolt on the starter frame of a 60 Dodge. It was OK and tight on the cable, but the nut UNDER the lug was loose, (!) which allowed the stud to move sideways in the steel and touch the starter frame, (sometimes......!)drawing huge current and barely turning,, intermittently. This, from factory. Loose starter bearings or off center ends can let armature touch field poles, but only when starter is on, magnetism pulls it sideways. --that will totally kill output torque. New battery, generator , regulator , battery cables etc did nothing on that 60 Dodge, and a jump would start it , deflecting blame from the starter. Correctly tightening the under nut fixed it. So, I empathize.... Drove me crazy. Starter Ammeter is what found it. How much the headlights dim at cranking is a poor man's ammeter! The solenoid MUST make the main contact solidly and be correctly assembled, as it will spin weakly while engaging, but full torque doe not come until solenoid shorts out the pull in winding , which happens after pinion is almost all the way in. Tolerances in this are critical, someone may have rebuilt wrong. There is no need to run a ground right to the starter, as the engine block has a very low electrical resistance. In fact shorter, heavier cables and a big fresh battery matter most . The thinking should be: the stock setup is fine, something is wrong somewhere..they knew what they were doing. . At a bare minimum , you need a starter ammeter, and a voltmeter..and compare with a good car. 300F does not crank easily, but stock works fine. Hope this helps, John Grady PS, gear reduction or "geared mini starters" non stock are better, but original is fine too. They are better as they have permanent magnets, no field winding, gear down gives it more torque at same current draw.

J.Y. ----- Original Message ----- From: Thomas Cox To: Chrysler300@xxxxxxxxxxxxxxx ; parts@xxxxxxxxxx Cc: donbelton313@xxxxxxxxx Sent: Monday, March 29, 2010 10:14 PM Subject: [Chrysler300] Battery/Starter-300F Thanks to the many folks that have given advice. A summary of the suggestions: 1. Make certain the ground connection is to clean metal giving a good ground. 2. Have the rebuilder use heavier winding materials. 3. Ground the battery to the starter (with clean, unpainted connection). 4. Cool the starter with water to see if a reduced temperature makes the problem lessen to confirm the starter problem. After all these, I contacted Jeff Carter who has bailed me out of many difficult issues with the 300F build. He indicated, in agreement with all the above, that it is likely a starter problem that may be due to multiple starter rebuilds (or just age) where the field windings have deteriorated to the point that they have too much resistance and are not funcioning properly and when the starter gets hot, it does not provide the electrical boost needed. That, and the probability that the windings of the armature are not the heavier-duty variety. He no longer knows of a shop that has the knowledge or the parts to do a proper rebuild with new field windings and armature rewinding. Do any of our members have a starter shop that has this experience and parts to do a complete and proper rebuild? It seems that may be the best solution to the problem at hand. I imagine other folks are having, or will have, a similar need. Louie Barrie indicated that he had a fellow with a great deal of knowledge about these things. Any leads would be greatly appreciated.
