oil pump
I read that there is a different oil pump for the b engine. How can I tell the difference? I was given a pump along with the b block and the guy that gave me the block got them in a yard cleanup.

Re: oil pump
The model B pump shaft with the gear on the bottom is less diameter than an A shaft . The body is cast and has a rough finish . The oil outlet are two vertical slits each side . I think the A has round holes not sure I dont have one to compare .

Re: oil pump
Somewhere I saved a photo of 7 or 8 different "Earl" pumps side by side from early 28 to 1933.

Otherwise, there is no telling what could have been mixed around or modified over the years. I have found various modifications: enlarged intake and outlet ports and pumps modified for pressure by brazing in passages at the upper end, fabbed-on pressure relief valves, etc. |

Re: oil pump
The "turned down" section of pump shaft was 1/2 turned down to .410 as I remember.
Note: Berts stocks the A-6600 .500 shafts which are turned down to .410 per original Service Bulletin dimensions. Last edited by Benson; 07-02-2021 at 07:45 AM. |

Benson, Thanks for the "B" owners manual info. I've been looking for the instructions it provides for timing "B" distributors for some tine now! Bob-A Skirts are for women and not car fenders! |

Re: oil pump
Fit and functionally, the Model "A" oil pump with all service bulletins incorporated and Model "B" oil pumps are the same.
One telltale feature is that the Model "B" pump has a rectangular oil outlet in contrast to the Model "A" oil pump which has a round outlet.
