1940 Ford
The Green Bible on page 303 shows part # 78-7085- B as the retainer (trans. main shaft bearing) at the rear of the 3 speed transmission used in 1937-40 90 HP cars and also 1939-41 commercial trucks. This is also commonly called the rear transmission mount.
On the same page of the Green Bible is shown part # 21A-7085, retainer (trans. main shaft bearing) used in 1942-48 8 cylinder 90 and 100 HP v-8 cars. Also called rear trans. mount. QUESTION: Are parts 78-7085-B and 21A-7085 retainers interchangeable? The center to center measurement of the bolt holes is 8 inches. They both look like the one shown here except for the center to center distance on mine is 8 in., not 10. https://www.jalopyjournal.com/forum/...-7085.1205073/ Last edited by 19Fordy; 02-08-2024 at 04:56 PM. |

Re: 1940 Ford
They will both bolt up to the rear of the transmission. The 21a part has a shorter center to center distance than the 78 part.
The 21a part will not match your '40 chassis.

Re: 1940 Ford
Kube, Thank you very much for answering my question. I have attached a photo of my OEM 1940 transmission that is still in the car. Do you happen to know what the center-to-center distance is on the 1940 retainer shown in photo of my 40 below?
I took the photo years ago but didn't check the center line to center line of the holes. Thanks, JIM |

Jim ..... The 78-7085 retainer measures 10" between holes on center. The 21A-7085 measures 8" on center. The 99A-7085 also measures 8" between holes on center. Coop . Last edited by V8COOPMAN; 02-08-2024 at 08:43 PM. |

Didn't we go through this a couple of months ago? Yours being so thick appears like 60HP. Last edited by Terry,OH; 02-09-2024 at 10:33 AM. |

Re: 1940 Ford
THANK YOU all very much for delving into my question and providing valuable measuring info. re: hole center line distance. I didn't know about the 8 in. and 10 in. difference.
The current retainer on my 40 was on the OEM transmission (still in the car) when I bought the 40 in 1963. If I ever need to replace it, I will be sure to check the part #. |

Re: 1940 Ford
Bill Schwartz, I am pretty familiar with 40 Fords, where does the brass connector you speak of go?

Re: 1940 Ford
Bill,
I found your email in my "Spam" folder and have replied. Coop, Thanks for the compliment. I am actually getting embarrassed. |
