49 Special Deluxe Posted March 2, 2019 Report Share Posted March 2, 2019 Hello wise forum. My 1949 P18 has been converted to 12v at some point in its life. It currently has a 12v Lucas M45G starter. The starter has decided that it doesn't want to play the game any more and is kaput. My question is, is there an 12v aftermarket starter available for the 218 230 that bolts straight in? Thanks in advance. Quote Link to comment Share on other sites More sharing options...
plymouthcranbrook Posted March 2, 2019 Report Share Posted March 2, 2019 I have read that for a starter you can run a 6 volt one on 12 volts without harm if you don't crank a lot. Have no personal experience with it but you might want to look into it. 1 Quote Link to comment Share on other sites More sharing options...
Andydodge Posted March 2, 2019 Report Share Posted March 2, 2019 I'd be very surprised if there was an aftermarket starter available in the same manner as the various Hi Torque starters that exist for various V8's...........could be wrong but have you tried any local older established auto electricians?......also suggest you try Castle Auto Electrics, CAE in Castlemaine, Vic, 03 5472 1442 and Jim Robinson also in Vic, 03 5461 4619.......just checked my 1946-53 Manual, 1954 Supplement and 1957-62 Chrysler Royal Manuals and the M45G starter is the one listed from 1953 when 12 volts was introduced into Oz cars, thru to 1962 for all the Oz sixes, which seems like both the 23 and 25 inch engines used the same starter............dunno if this helps........andyd Quote Link to comment Share on other sites More sharing options...
ptwothree Posted March 2, 2019 Report Share Posted March 2, 2019 Yeah, I'm not too comfy with my 6 volt starter drive slamming the flywheel on 12 volts. Seems like a '56 12 volt starter is the fix vut are hard to find and $$$$ wdhen found. Maybe a shop could install 12 volt field coils but I haven't looked into that yet.

kencombs Posted March 3, 2019 Report Share Posted March 3, 2019 Just a point of information. Dad and I converted a 54 chev 1t to 12v back in 61. It was used as our shop truck and tow rig for 12 years or so. Many starts 6 days per week. Never had a failure. But, boy it it crank over! 1 Quote Link to comment Share on other sites More sharing options...

Looks like it can be done as described. A friend with his flat 6 mopar was talking to our local electrical shop- -Modesto Electric, Modesto, Ca. said to him a change 6volt field winding's to 12 volt windings was no issue- -No Problemo. ?

schwy Posted April 11, 2019 Report Share Posted April 11, 2019 When using a 6v starter with a 12v system are you getting a grinding of teeth right away. I get a grind pull off the floor push and slowly allow the teeth to mesh when it slows but still spins.? I Quote Link to comment Share on other sites More sharing options...
Cold Blue Posted April 11, 2019 Report Share Posted April 11, 2019 I am using the original Autolite starter, 6 volt, on my 1948 Plymouth P15 with the 218 flathead motor, which has been converted to 12 volts. Had a problem with the starter clashing into the flywheel teeth. It finally broke the cast iron housing assembly. Fortunately for me, it did not damage the flywheel teeth. I found a NOS housing on Ebay, and reinstalled the starter. Still it whacked when first engaging. I found a fix. I replaced the original starter bendix with a bendix from the 1952 thru1954 Plymouth cars. It is called a "follow-thru drive assembly" in my manual. The manual says it can be used on all 1946-1954 Plymouth cars. Installation of the "new" bendix fixed my problems. Don't know if it can be used on a Dodge, but just maybe??? Hope this helps.. 1 Quote Link to comment Share on other sites More sharing options...
Young Ed Posted April 12, 2019 Report Share Posted April 12, 2019 I believe someone on the forum sourced via ebay a modern starter that was adapted to the flatheads. Quote Link to comment Share on other sites More sharing options...
