Re: New baby 1953 Merc
When I went looking for replacement fluids and lubricants for my 1956 Ford 850 tractor some years ago, I ran in to the same thing. Lots of difference from on person to the other. I've been doing my own research ever since.
Any fluid or lubricant is better than none at all. The days of the old whale oil ATF, GL-3 gear lube, and easily sourced single viscosity motor oils are long gone. |

Re: New baby 1953 Merc
When did they start putting filters in transmissions? The Merc-O-Matic, doesn't have a filter in the transmission.

Re: New baby 1953 Merc
They are a cleanable screen, they didn't have replaceable filters like they do in the more modern era. If a lot of metal gets generated due to a clutch or bearing failure then they get all kinds of crap past the screen and into the system. Cleaning all that out of a valve body is not an easy task.

For some reason I had 56 MERC caught in my mind. Don't order the filter kit yet.

Re: New baby 1953 Merc
Lycoming engines have come with oil screens for years. Clean them every 25-hours & no problems. Replace if you want but it's not absolutely necessary as long as a person knows how to clean them. What ever gets through a screen will come back out.

Re: New baby 1953 Merc
OK, I got nervous and jerky thinking you went to a later drive-train. Old Man Jitters.
Any-who, the actual mid-case was not introduced until the 1955 model run. The trans MERC used before was the small case but was named the MERC-O-MATIC for their advertising reasons. The ad you showed threw me also as it says 1952-53 and 56. I see where a small case may have been used in some 56 MERC's. Let's just hope the kit it is quality. I was never really interested in anything much before 1957 so bear with me.

Now I remember why I was having an issue with the screen filter. The book assigns it a number (77488) but when to go to look up the number, it doesn't exist, it jumps right over the number. I have had that issue with other parts too. Last edited by Merc Cruzer; 06-22-2021 at 08:39 PM. |

Re: New baby 1953 Merc
LINC-MERC used basically the same PN SYSTEM during this period as FORD. Some BASIC PN's were the same as FORD, some were unique to the LM car lines. FORD began the P&A SYSTEM in 1959 and LM was brought into FORD after the demise of the EDSEL (1960) (MEL).
You will not find any references to that cataloging today as everything was superseded or changed. Early Case MERC-O-MATIC Filter/Screen - 1P 77748-A You will find BPN 77748 later in sequence as it is a five character BASIC PN (the 5th character being an expansion number) in the MERC-O-MATIC AT section. I doubt you would find a NOS and everything now is outside vendor

Re: New baby 1953 Merc
Kultulz knows his Ford part numbers. I'm pretty sure the small case air cooled transmission was used up until early in 1959 for certain light duty applications while many of them were changed over to radiator cooling in 1956. The superseded number is dropped from the parts line if a new numbered part shows up.
Some of the numbers were Borg Warner numbers too so that can cloud the issue some. Fatsco and likely several other suppliers have the screens but I don't know what their part number may be. The latest OEM part number I could find is B9AP7A098B but there a more in the aftermarket range that don't resemble any of the old OEM numbers. |

FORD-O-MATIC HISTORY - 1951-55 and 1955/

So there is the early history and explains the 1951-54 and 1955/ differences. No BW vendor numbers as FORD actually owned the trans unlike the BW manual transmissions.

Re: New baby 1953 Merc
KULTULZ,
Thanks, I am getting a better feel for the trans with each passing post. It appears, the Ford-O-Matic and the Merc-O-Matic were the same from 51'-53'. Later the Merc-O-Matic got a larger case and a different valve body, due to increased HP. |

Re: New baby 1953 Merc
Correct - 1955 the game changed somewhat. FORD was allowed to do its' own engineering at that point and I guess corrected some of the original BW design. I always thought the 1951-1960 F/M was the same basic unit. Like I said, I never really got into pre-1957 so this was a learning exercise for myself also.
- Any ID TAG beginning with 1P was the early F/M (MODEL YEAR 1951 THRU 1954). - 1955/ ID began with a four character prefix, similar to a PART NO prefix. - EDIT - Above not quite true/concise - Detail to follow. *********************************************** Now there is a continuation to this as FORD supposedly bought out the BW design and came out with the FMX for the 1968 model year. OH! While you are under the car, can you try and measure just the main case length? This will give me closure ... EDIT - Main Case Size Chart Shown Below (Hopefully) ...G-R-R-R-R One of these days I may get my act together. Look for upcoming EDIT - PART 2
