10A3 on the A plus head fitted is the date stamp 10th January 1983--if it had 12G940B on heater valve end of head it would be a 1993 head

G'day Mike:

Despite its age, the original request for information was left unanswered... until now. Somebody finally got an answer to his question. Sometimes it takes a long time to find information.

.

"Hang on a minute lads....I've got a great idea."

g'day

Are you aware you just responded to a 2yr old thread to a person who has posted exactly twice to this board?

Hi,
i would like to know the differences between this gold seal unit (BHM1209E) and original 12h719 or 832.
this engine actually is fitted in an innocenti 1300 export but i am not sure that the head is the correct one.

  • As i can see other 2 gold units were avaible:
  •  

38G559E       1275cc - Gold Seal unit with Simplex cam drive gears for engine numbers prefixed

                               12H719 and 12H832, for 1300GT (ADO16) and Innocenti 1300, 11-stud

                                 cylinder head


GSE1109E    1275cc - Gold Seal unit for 1300GT (ADO16) and Innocenti 1300, 11-stud cylinder

                               head
And for theese units it is specified that they have an 11 stud head (like the 12h719 or 832).


But in my case :

BHM1209E   1275cc - Gold Seal unit, replaced all Innocenti 1300 engines from engine numbers

                               prefixed 12H610, 12H635 and 12H832
                      
                       it is not specified if this refurbished engine have a "classic" 9 or 11 stud head.


The innocenti i was talking about, fits a BHM1209E but the head is only 9 stud, so .. is it wrong?
On the head is stamped "10A3", anyone knows something about that?





Thank's to everyone and sorry for my bad english
