I have a 1928 engine with new pistons/ bearing.
The original starter # 710-c will not turn the engine.Battery and cables are in good condition.
I have try many # 710 starter, but they will not turn,or very slow. Then I put in a # 714 starter.
This starter turn the engine very easy.This starter have 10 teeth ,and the original have 11 teeth bendix.
Are the # 714 starter stronger, or do the 10 teeth bendix a stronger rotating? :rolleyes:

Regards Arvid

Both my 1928 starter motors are original 1928 starter motors. They are Model 943B Delco-Remy with 10 teeth bendix. They both work well.

Model 943-B is a 1928 Generator, not a starter.

I have to laugh. Must be too many Christmas parties! My starters are # 710-c with ten teeth bendix.

Hello Arvid,
The correct model starter motor for a 1928 Chev is a Delco-Remy 710-D.The 714-L fits Chev's from 1929 to 1932,as well as 1933 & 1934 Std model 6 cyl Chev's.
The 710-C starter is the same as the 710-D,
except the 710-C is a Remy starter.With either the 710-C or D starter you can run an 11 or 10 tooth bendix pinion gear,as the flywheel ring gear has 110 teeth,all that changes is the cranking ratio,10:1 or 11:1.
With using the 714-L starter,the front
mounting housing that bolts to the flywheel housing is a different length from the barrel to the mounting flange,and the pinion gear could either not engage properly with the ring gear teeth,or engage too deeply,and smash off the pinion gear counterweight,as well as possibly damage the flywheel ring gear teeth.
Added to all this,you have a mechanically operated starter switch mounted on top of the 714-L barrel,which you would have to replace with a terminal stud to connect the field leads into,as well as your switch lead.
If the starter still turns over slowly,it probably needs an overhaul.The shafts on these can bend,as well the drive end housing bush wears out too.The commutator endplate has no bush originally,the shaft runs straight in the cast iron endplate,and if not oiled,as per the owners manual,it can wear badly as well.All this can lead to the armature "poling" ie.the armature rubs against the field pole pieces.
This will cause the starter to crank very slowly,as will leads of insufficient size.

Hello Kevin.
You are correct.The 714-L starter are different.
This can not be used in a 1928 engines. It's longer and have a mechanically operated starter switch mounted on top. But not the 714-C. This one has the same measurements as the 710-C and with a terminal stud to connect the field leads. I have several overhaul 710-C starters but they will not turn the engine proper. I think I will use the 714-C. It's work very well.
The engine are very tight after drilling and new pistons. Do you know what car the 714-C was used?

Could not find a listing for the 714-C. Did find 714-B was used on Federal and White trucks. The interchange on the starter armature for the '27-34 Chevy Delco starters is:
'29-30 Auburn, '29 Chrysler, '29 DeSoto, '29 Elcar, '29-31 Gardner, '29-30 Graham-Paige, '29-30 Kissel, '29-32 Marmon, '29 Moon, '29 Oakland, '29 Peerless, '29 Plymouth, '28-29 Pontiac, '32-35 Reo, '29-30 Roosevelt, '29 Studebaker, '29 Windsor. Maybe that will give a clue.

Hi Arvid and Chipper,
I had alook through my reference books,and found three listings for the 714-C starter motor.
This model starter motor fits:

1926 Pontiac

1927 Pontiac 6-27

1930-31 Marmon-69

The DELCO-REMY P/No. for the armature to suit the cars Chipper listed is:816163.This number is stamped on the laminations of the armature core.Hope this information is of some help.

Thank you Chipper and Kevin
It was great information to know.
A Merry Chistmas to you
